ABSTRACT (maximum 200 words) 



The U.S. Marine Corps concept for the projection of naval power ashore is Operational Maneuver From 
the Sea (OMFTS). OMFTS calls for movement of Marines from ships at sea directly to objectives deep inland 
without requiring a pause to build-up combat power on the beach. Support for ground forces is expected to 
come from the sea, and be delivered primarily by air. This demands that sea-based logistics assets remain 
sufficiently close to shore to allow air assets to conduct resupply operations directly to the battlefield. The 
implication of this is that Navy ships may sacrifice operational and perhaps tactical mobility while sustaining 
the Marine operation. 

This thesis determines the distance from the coastline sea-based Combat Service Support (CSS) assets will 
be able to maintain and still support operations of a given magnitude, and how tactically constrained Navy ships 
will be in order to support this concept of expeditionary warfare. It focuses on the time-distance-weight/volume 
relationships involved, and takes into account characteristics of the resupply assets, such as aircraft availability 
capacity, method of employment, and the effects of combat attrition. Three methods of employing a Marine 
Expeditionary Unit are studied, ranging from a traditional force mix to the use of small infestation teams. The 
analysis shows that the available CSS assets will not support a traditional ground force mix at the distances 
envisioned, but will support the use of small teams. To fully realize OMFTS and still allow ships to maintain 
the desired standoff from shore will require a shift to more lethal Marine forces with much smaller logistical 
demands. Until such a force is feasible, the Navy should plan on providing support to Marines from close to 
shore.

ABSTRACT 

The U.S. Marine Corps concept for the projection of naval power ashore is 
Operational Maneuver From the Sea (OMFTS). OMFTS calls for movement of Marines 
from ships at sea directly to objectives deep inland without requiring a pause to build-up 
combat power on the beach. Support for ground forces is expected to come from the sea, 
and be delivered primarily by air. This demands that sea-based logistics assets remain 
sufficiently close to shore to allow air assets to conduct resupply operations directly to the 
battlefield. The implication of this is that Navy ships may sacrifice operational and 
perhaps tactical mobility while sustaining the Marine operation. 

This thesis determines the distance from the coastline sea-based Combat Service 
Support (CSS) assets will be able to maintain and still support operations of a given 
magnitude, and how tactically constrained Navy ships will be in order to support this 
concept of expeditionary warfare. It focuses on the time-distance-weight/volume 
relationships involved, and takes into account characteristics of the resupply assets, such 
as aircraft availability, capacity, method of employment, and the effects of combat 
attrition. Three methods of employing a Marine Expeditionary Unit are studied, ranging 
from a traditional force mix to the use of small infestation teams. The analysis shows that 
the available CSS assets will not support a traditional ground force mix at the distances 
envisioned, but will support the use of small teams. To fully realize OMFTS and still 
allow ships to maintain the desired standoff from shore will require a shift to more lethal 
Marine forces with much smaller logistical demands. Until such a force is feasible, the 
Navy should plan on providing support to Marines from close to shore.

EXECUTIVE SUMMARY 

The U.S. Marine Corps concept for the projection of naval power ashore is 
Operational Maneuver From the Sea (OMFTS). Like Forward ... From the Sea, it 
emphasizes the world's littoral regions as areas for potential conflict, and the role of the 
Naval Expeditionary Force (NEF) in those conflicts. The availability of inexpensive 
advanced weapons and sensors to potential adversaries will make traditional amphibious 
methods of ship-to-shore movement and lodgement ashore more risky. To reduce this 
vulnerability, OMFTS calls for movement from ships at sea directly to objectives inland 
without requiring a pause to build up at a beachhead. To accomplish this, assault forces 
must be lighter and faster, and a great deal of command, control, communications, 
computers, intelligence (C4I), combat service support (CSS), and fire support (Naval Surface 
Fire Support and Close Air Support) must be sea-based. 

The U.S. Marine Corps Commandant's Warfighting Laboratory was established in 
October, 1 995 to develop and test advanced technologies and operational concepts to support 
OMFTS. The developmental process is known as Sea Dragon. One of the concepts under 
development envisions small, highly mobile teams dispersed over a battlefield up to 200 x 
200 nautical miles in size. These teams would infest an area, identify critical targets, and 
engage selected targets by calling in precision fires. The desired capability is to achieve the 
combat power of a large force spread over the entire battlefield while not presenting a large, 
fixed target to retaliate against. Major support for these units, in the form of command and 
coordination, fires, and sustainment, will all remain at sea. 

One of OMFTS's goals is to reduce the buildup of forces and equipment ashore. 
Delivery and sustainment of ground forces is expected to come directly from the sea. 
primarily by air. This demands that sea-based logistics assets remain sufficiently close to 
shore to allow air assets to conduct resupply operations directly to the battlefield. One 
implication of this is that Navy ships may have to sacrifice operational and perhaps tactical 
mobility to sustain the Marine operation. 

The thesis determines the distance from the coastline that sea-based CSS assets will 
be able to maintain and still support MEU-sized OMFTS operations using either traditional

forces or small infestation teams. It focuses on the time-distance-weight/volume 
relationships involved in the delivery and sustainment of forces ashore, and takes into 
account characteristics of the resupply assets, such as aircraft availability and capacity, and 
the effects of attrition. The objective is to provide pragmatic quantitative estimates as to 
how tactically constrained the Navy ships will be while supporting this new form of 
expeditionary warfare under a wide variety of circumstances. 

OMFTS, as envisioned, precludes surface resupply. Surface resupply over land 
requires secure land lines of communication and ground transportation. The distances 
involved require defense of these lines of communication, just as a beach CSS area would. 
CSS must be provided by air. This thesis measures the outer limits of airborne CSS of a 
MEU(SOC) based on the airlift assets in a future MEU as it is now planned. 

The analysis shows that when OMFTS is conducted using traditional forces, the 
envisioned amphibious ship standoff of 50+ NM is difficult, and is not possible in a non- 
permissive air environment. Shifting to a non-mechanized force does not ease the problem 
because of the increased airborne troop movement requirements. Shifting to the use of 
infestation teams helps somewhat. However, the current practice of sending a two-aircraft 
section severely limits the possible range capability, because their payload is so light. If 
only one aircraft is sent to resupply or move a team, there is a huge increase in range. 
Increased capability could be achieved by a number of different measures, such as increasing 
the number of aircrews, increasing the number of aircraft, reducing the number of aircraft 
used per mission, and exploiting the combat power of an accompanying carrier battle group. 

To realize the full value of OMFTS, there must be a shift to more lethal forces with 
smaller logistical demands, or a sizable increase in airlift capability. To maintain a safe 
standoff from shore, maintain operational flexibility, and still support OMFTS, the Navy will 
need to push development of inshore combat tactics through means similar to those 
undertaken by the Commandant's Warfighting Lab. Influencing events ashore is more than 
being able to strike deep inland with precision weapons and aircraft. It is the ability to affect 
the campaign deep inland with forces on the ground. Until a lighter, more lethal Marine 
force is feasible, the Navy should plan on providing support to Marines from close to shore. 



I. INTRODUCTION 

A campaign plan that cannot be logistically supported is not a plan at all, but simply an 
expression of fanciful wishes. John F. Meehan III (Meehan, 1993). 

And it ought to be remembered that there is nothing more difficult to take in hand, more 
perilous to conduct, or more uncertain in its success, than to take the lead in the introduction 
of a new order of things. Because the innovator has for enemies all those who have done 
well under the old conditions, and lukewarm defenders in those who may do well under the 
new. This coolness arises partly from fear of the opponents, who have the laws on their side, 
and partly from the incredulity of men, who do not readily believe in new things until they 
have had a long experience of them. Nicollo Machiavelli (Machiavelli). 

A. OBJECTIVE OF THESIS 

The U.S. Marine Corps concept for the projection of naval power ashore is 
Operational Maneuver From the Sea (OMFTS). Like Forward ... From the Sea, it 
emphasizes the world's littoral regions as areas for potential conflict, and the role of the 
Naval Expeditionary Force (NEF) in those conflicts. The availability of inexpensive 
advanced weapons and sensors to potential adversaries will make traditional amphibious 
methods of ship-to-shore movement and lodgement ashore more risky. To reduce this 
vulnerability, OMFTS calls for movement from ships at sea directly to objectives inland 
without requiring a pause to build up at a beachhead. To accomplish this, assault forces 
must be lighter and faster, and a great deal of command, control, communications, 
computers, intelligence (C4I), combat service support (CSS), and fire support (Naval Surface 
Fire Support and Close Air Support) must be sea-based (U.S. Marine Corps, 1996). 

The U.S. Marine Corps Commandant's Warfighting Laboratory was established in 
October, 1 995 to develop and test advanced technologies and operational concepts to support 
OMFTS. The developmental process is known as Sea Dragon. One of the concepts under 
development envisions small, highly mobile teams dispersed over a battlefield up to 200 x 
200 nautical miles in size. These teams are referred to by several different names. One that 
is commonly used is reconnaissance assault platoons (RAPs). and this will be used in this 
thesis. The RAPs would infest an area, identify critical targets, and engage selected targets 
by calling in precision fires. The desired capability is to achieve the combat power of a large 



force spread over the entire battlefield while not presenting a large, fixed target to retaliate 
against. Major support for these units, in the form of command and coordination, fires, and 
sustainment, will all remain at sea (Commandant's Warfighting Laboratory, 1997). 

One of OMFTS's goals is to reduce the buildup of forces and equipment ashore. 
Delivery and sustainment of ground forces is expected to come directly from the sea, 
primarily by air. This demands that sea-based logistics assets remain sufficiently close to 
shore to allow air assets (CH-53E, MV-22) to conduct resupply operations directly to the 
battlefield. One implication of this is that Navy ships may have to sacrifice operational and 
perhaps tactical mobility to sustain the Marine operation. 

The thesis will determine the distance from the coastline that sea-based CSS assets 
will be able to maintain and still support MEU-sized OMFTS operations using either 
traditional forces or RAPs. It will not explore the validity of the RAP concept itself, or the 
other issues (prominently C4I and fire support) involved with its employment. The thesis 
will focus on the time-distance-weight/volume relationships involved in the delivery and 
sustainment of forces ashore. It will take into account characteristics of the resupply assets, 
such as aircraft availability and capacity, and the effects of attrition. The objective of this 
thesis is to provide pragmatic quantitative estimates as to how tactically constrained the 
Navy ships will be while supporting this new form of expeditionary warfare under a wide 
variety of circumstances. 

It must be remembered that the Marine Corps will continue to be prepared to conduct 
traditional amphibious operations, Sustained Operations Ashore (SOA). and Operations 
Other than War (OOTW), as well as Operational Maneuver from the Sea. But, some forms 
of OMFTS are drastic departures from traditional operations in the demands placed on 
logistics, C4I, and fire support in return for the greatly expanded area of influence of a 
Marine Air-Ground Task Force (MAGTF). For this reason, OMFTS is the focus of this 
thesis. 
B. SHIP TO OBJECTIVE MANEUVER (STOM) 

Traditional amphibious maneuver from the sea is a three-step process: (1) maneuver 
in ships; (2) transition ashore; (3) maneuver ashore. Step (1) allows much more flexible 



positioning of forces than can be achieved by forces ashore. While the defending forces 

must cover all possible avenues of entry, the sea-borne forces may choose when and where 

to attack. Step (2) is the movement of land combat units ashore, and requires an assault to 

secure a lodgement on the beach from which to execute step (3). The time required to 

complete step (2) often offsets the advantage gained by step (1). By the time sufficient 

combat power is on the beach, a support area secured, and units are ready to commence 

maneuver on land, the enemy often will have had time to prepare a defense or counter attack 

(Lyons and Magwood, 1994). OMFTS, using STOM, seeks to eliminate step (2), the 

transition ashore. This will be made possible by technological advances in mobility- as well 

as advances in fire support and C4I. 

The goal of Ship-to-Objective Maneuver is to apply the principles and 
tactics of modem land maneuver to amphibious battlefields. Specifically, we 
will conduct combined arms penetration and exploitation operations from 
over the horizon at sea directly to the accomplishment of objectives ashore, 
without stopping to seize, defend, and build up beaches, landing zones, or 
other penetration points (U.S. Marine Corps, 1995). 

C. SEA DRAGON 

Sea Dragon is the development process for new, high-risk concepts to support 
OMFTS. The Commandant's Warfighting Laboratory (CWL) is tasked with field testing 
advanced technologies and concepts in order to identify those with promise as well as those 
that should be pursued no further at present. One of the concepts to emerge from this 
process is the use of light, dispersed, foot mobile teams empowered with advanced C4I and 
remote, on-call fire support to engage an adversary indirectly. The intent is to provide the 
massed weapons effects of a large force while not presenting a massed target. These units 
have very little combat power of their own, and rely on improved, timely fire support more 
than do traditionally organized units executing STOM. The dispersion and size of these 
units require that they be stealthy and mobile in order to survive and be effective. This 
requirement for speed and stealthiness also applies to their means of deliver}' and support. 
The CWL is exploring resupply methods that will enable an aircraft to deliver support 



without compromising the location of the supported units (Commandant's Warfighting 

Laboratory, 1997). 

D. NAVY LITTORAL CONSIDERATIONS 

OMFTS requires C4I/fires/logistics to be based at sea to the maximum extent 
possible. Thus, Navy vessels must remain close enough to supply the just-in-time support 
entailed. This task is complicated by dangers associated with the littorals: 

• Mines. The inability to rapidly detect and clear mines forces ships to remain 
further away from shore. 

• Anti-ship missiles (ASMs). Low-observable, high speed ASMs leave a very 
small time window in which to defend. Even with Cooperative Engagement 
Capability (CEC), depth of fire is required for safety. 

• Diesel submarines. These operate close to shore, and shallow-water 
antisubmarine warfare (ASW) is difficult. 

• Small coastal craft. The U.S. Navy is comprised of blue water warships and is not 
well suited for defending against small craft. 

Traditional amphibious operations require amphibious shipping to approach within 
10.000 yards of the beach. STOM envisions a minimum standoff of 25 NM for deployment 
of AAAVs, 40 NM for LCAC operations, and 50 NM or greater for aircraft operations (U.S. 
Marine Corps, 1995). Ideally, capital ships (CVN, LHD/LHA, and Arsenal ship) would 
remain more than 100 NM from shore. 



II. ASSUMPTIONS AND METHODOLOGY 

A. SCOPE OF THE PROBLEM 

This analysis is limited to a Marine Expeditionary Unit, Special Operations Capable 
(MEU(SOC)) Marine force, the Navy ships and aircraft present in a typical Amphibious 
Ready Group (ARG), and a 15-day duration of operations with no external support. Only 
the logistical aspects (Combat Service Support) of OMFTS are considered. The required 
advances in C4I and fire support have not yet been achieved, but a sufficient capability is 
assumed for the time frame of this study, 2010-2015. 

Combat Service Support has six functional areas: Supply, Maintenance, 
Transportation, General Engineering, Health Services, and Other Services (U.S. Marine 
Corps, 1993). This analysis is concerned primarily with the supply and transportation 
functions, with some consideration to the transportation requirements for health services. 
The other areas are assumed to remain at sea and are not considered. 

B. METHODOLOGY 

This analysis is broken into two main components: the determination of support 
requirements and an analysis of the ability to satisfy those requirements. Chapter III deals 
with the determination of requirements, and has three steps: 

• Identification of the forces to be supported. 

• Identification of the supporting assets and their characteristics. 

• Determination of support requirements based on this information. 

Chapter IV details the supportability analysis, which has two steps: 

• Determine the maximum distance at which assets can satisfy force delivery 7 and 
support requirements. 

• Assess the effects of aircraft attrition on maximum support distance. 



III. DETERMINATION OF REQUIREMENTS 

A. IDENTIFY FORCES TO BE SUPPORTED 

The Marine Corps deploys its combat assets as a MAGTF, a combined arms force 
consisting of a Command Element (CE). an Air Combat Element (ACE), a Ground Combat 
Element (GCE). and a Combat Service Support Element (CSSE). A Marine Expeditionary 
Unit Special Operations Capable (MEU(SOC)) is the smallest MAGTF, with the following 
typical composition: 

• CE - Has detachments of the following: 

Force Reconnaissance Company 

Radio Battalion 

Air and Naval Gunfire Liaison Company (ANGLICO) 

Communications Battalion 

Intelligence Company 

• ACE - A reinforced helicopter squadron and a Marine Air Control Group 
detachment consisting of: 

12 CH-46E medium lift helicopters 
4 CH-53E heavy lift helicopters 

3 UH-1N light utility helicopters 

4 AH-1 W light attack helicopters 

6 AV-8B VTOL fixed-wing light attack aircraft 

2 KC-130 tankers (on standby in CONUS) 
5+ Stinger missile teams 

• GCE - A Battalion Landing Team (BLT) consisting of a reinforced infantry- 
battalion: 

3 Rifle Companies 

1 Weapons Company 

1 Artillery Battery with six Ml 98 155mm Howitzers 

1 Light Armored Reconnaissance Platoon with seven LAVs 

1 Assault Amphibian Platoon with 12 AAVs 

1 Combat Engineer Platoon. 



B. IDENTIFY SUPPORTING ASSETS 
1. Shipping 

A MEU(SOC) deploys embarked on an Amphibious Ready Group (ARG). An ARG 
may have three to four ships, but usually consists of an LHD or LHA, an LPD, and an LSD. 
Table 1 summarizes the Landing Craft-Air Cushion (LCAC) and aircraft capacities of these 
ships (Betaque, 1995).

Table 1. ARG component LCAC/aircraft capacities 

The LHA or LHD is the primary aviation ship and carries the Command Element 
of the MEU. The LPD has both a well deck and limited aircraft capability. LPD- 17 is 
currently under development. It will be more survivable and stealthy than current 
amphibious ships and will be the best suited member of the ARG to come in close to shore, 
if needed. The LSD is primarily a well-deck ship. All of the ships will carry some 
components of the embarked MEU(SOC). 

2. Aircraft 

The medium-lift aircraft in 2010-2015 will be the MV-22 tiltrotor. It replaces the 
CH-46E and CH-53D. It doubles the speed of the CH-46 and quadruples the range. The 
MV-22 has an internal capacity of 10,000 pounds at a radius of up to 500 NM (Turley, 
1989). While the MV-22 has a substantial external lift capability (15,000 lbs. vs. 4,000 lbs. 
for the CH-46E), it comes at the expense of speed. The MV-22 cruises at 240 knots with an 
internally carried load, while external load operations require an airspeed of 150 knots or 
less. 1 



'This is not due to the flight characteristics of the MV-22, but of the external load. 



The USMC heavy lift helicopter is the CH-53E. With an external load capacity of 
32.000 lbs., it is the only helicopter that can transport the LAV or the M198 155 mm 
howitzer. The CH-53E can also provide a forward refueling capability using the Tactical 
Bulk Fuel Delivery System, CH-53E (TBFDS, CH-53E). This is a quick install and uninstall 
fueling system which is carried internally. It can provide up to 2,400 gallons of fuel and has 
the necessary fueling equipment to act as a forward refueling site for aircraft or land vehicles 
(U.S. Marine Corps, 1997). Table 2 summarizes the characteristics of the MV-22 and 
CH-53E.

Table 2. Aircraft Characteristics 2 

The projected ACE composition for 2010-2015 has the CH-46Es replaced one-for- 
one by MV-22s. This results in a footprint of 48 CH-46E-equivalent spots. This equals the 
maximum spots available in an LHA-based ARG, and only leaves three extra spots in an 
LHD-based ARG. 

3. Surface 

The LCAC is designed primarily to cany wheeled or tracked vehicles, artillery, and 
heavy equipment. It can carry up to 60 tons at more than 40 kts, and has a range of 300 NM 
at 35 kts (Naval Surface Warfare Center, 1997). Although highly mobile, the LCAC is fairly 
large and is unarmored. It would be difficult to use in the face of a defending force, and 
would generally come ashore after the Advanced Amphibious Assault Vehicles (AAAVs). 
An ARG will have six to eight LCACs 

The AAAV will enter service around 2006. It replaces the AAV7A1, and offers a 
greatly increased capability. It will travel over water at 25 kts vs. 6-8 kts, providing a truly 
over-the-horizon capability. Over land it will move at more than 45 kts. which will allow as

much mobility as the M1A1 tank. The AAAV will carry 18 fully-equipped Marines or up 
to 5,000 pounds of cargo, and will be armed with a 25 mm Bushmaster gun and a 7.62 mm 
machine gun (General Dynamics Land Systems, 1997). A typical MEU will have twelve 
AAAVs (Ashinhurst, 1997). 

4. New Technologies 

The Guided Parafoil Air Delivery System (GPADS) is a GPS-guided Parafoil capable 
of delivering loads of up to 42,000 pounds from altitudes of up to 25,000 feet. The parafoil 
has a 2.5 to one glide ratio to allow up to 12 miles of offset from the delivering aircraft 
(Kean, 1995). Smaller versions of this could be deployed from the MV-22. 

The Semi-Rigid Glider is a semi-rigid deployable wing and has been field tested by 
the CWL. The system resembles a hang glider and has a 30' wingspan. Weighing 1,200 
pounds, it can carry a payload of 500 pounds out to 20 NM from its launch point. Using 
GPS, it is accurate to within 100 meters (Evans, 1996). This system would allow some 
degree of stealth to the supported unit and also put the delivering aircraft at less risk. This 
system, as well as the GPADS, would allow resupply in weather precluding landing or direct 
ground delivery. 
C. DETERMINE SUPPORT REQUIREMENTS 

1. Force Mixes 

For a MEU(SOC) conducting OMFTS, three schemes of employment are analyzed, 
two using STOM and one using the Sea Dragon concept of RAPs. 
a. STOM Air and Sea Mix 

The first is an Air- and Sea-borne assault. The air component consists of two 
of the Battalion Landing Team's three rifle companies inserted by MV-22. The sea 
component consists of a Light Armored Reconnaissance platoon deployed by LCAC. and 
an AAAV platoon deployed directly from the ARG, carrying the remaining rifle company. 
The rifle companies would each be augmented by two Weapons Company HMMWVs, 
inserted by air. 

A notional deployment scheme for this mix would have the main body of the 
ARG close to 40 NM offshore to deploy LCACs and aircraft, while an LPD came to 25 NM 



10 



to deploy the AAAVs. Once surface units had been deployed and LCACs recovered, the 
ARG could withdraw to 50 NM or more offshore, possibly leaving an LPD or other flight 
deck capable ship to act as a Forward Arming and Refueling Point (FARP). The artillery 
battery would remain at sea, to be inserted and extracted by CH-53E for raids as needed. 
Implicit in this type of operation is that there would be no CSS area established at a 
beachhead. Because of this, the of the LCACs' heavy lift capacity could be used to move 
forces ashore, but not for the sustainment of those forces once deployed. Substantially all 
sustainment would be delivered by air. In addition, since two of the rifle companies are foot 
mobile only, there is a requirement for enough airlift to move at least one company up to 25 
NM per day. The daily support requirements of this force would be for the sustainment of 
the three individual rifle companies and the two armored units, and sufficient troop lift to 
move one of the rifle companies up to 25 NM (Blasiol, 1997). 

The high speed and mobility of the AAAV will see AAAV employments that 
resemble helicopter operations. FARPs will support AAAVs as well as helicopters 
(Ashinhurst, 1997). The scheme is for a MEU(SOC)s Battalion Landing Team, and for this 
force size, FARPs and other CSS areas will not be based ashore. Sustainment for AAAVs 
and LAVs will be delivered directly to the units, and aircraft fuel and ammunition support 
will come from the LHA or LHD, or from a sea-based FARP, such as an LPD brought closer 
to shore than the main body of the ARG. 

b. STOMAirMix 

The second scheme is an entirely air-inserted assault. The three rifle 
companies are inserted by air, with no mechanized component or HMMWVs. This scheme 
could be driven by lack of safe surface delivery routes, or an objective requiring too great 
a standoff from the beach. As in the first scheme, artillery would remain at sea and be 
delivered by CH-53E on demand. The support requirements for this force would be to 
sustain the three individual companies and provide airlift to move at least two of them per 
day.

c. Sea Dragon RAP Mix 

The third case is the most drastic departure from traditional operations and 
makes most use of the new Sea Dragon concepts. In this case the BLT organization would 
consist of 27 reconnaissance assault platoons and a mobile combined arms company 
(MCAC), made up of LAVs, AAAVs, and HMMWVs, as required. The RAPs are squad- 
sized units which would engage critical targets with remote fires. Fires could come in the 
form of naval surface fire support, close air support, or artillery raids. Nine of these units 
would be ashore at any time, with the remainder either preparing for insertion or recovering 
from the field. The MCAC would remain at sea and come ashore as needed, then quickly 
return to the ARG. The support requirements for this force assume that each of the nine 
teams will require one MV-22 movement or resupply action daily. 3 

2. Calculation of Requirements 

The supply requirements of each unit are for Class I (Food and Water), Class III 
(Petroleum, Oil, and Lubricants), and Class V (Ammunition). Class I (Food) is based on 
three Meals, Ready-to-eat (MREs) per Marine per day, weighing 1 .46 pounds per MRE. 
Class I (Water) is based on five gallons per Marine per day. Requirements for Classes III 
and V are obtained from the AAAV program office and a Center for Naval Analyses study, 
Project CULEBRA: Sea-Based Combat Service Support for Ship-to-Objective Maneuver 
(Supply and Transportation Analysis) . Table 3 summarizes the supply requirements for each 
of the GCE components (Adapted from Magwood, Lyons, and Nance, 1995 and Ashinhurst, 
1997). 
D. SPECIFY HOW SUPPORT ASSETS WILL BE USED 

1. MV-22 

As the medium-lift replacement aircraft, the MV-22's primary mission will be the 
movement and sustainment of troops. The preferred method used to resupply units in the 
field is to carry cargo externally, which allows for easy pickup and drop-off. and minimizes 



3 Note that this is a conservative estimate of RAP support requirements. These 
units are expected to be capable of operations for several days without resupply. Also, in 
some scenarios, some aircraft could resupply more than one unit per sortie.

the time the aircraft is at risk to enemy fire. While this requires that the aircraft fly slower 
than it could without an external load, in the past the added time was usually offset by the 
speed of loading and unloading. For the MV-22, however, the speed penalty for external 
loads is much larger (90 knots vs. 20 knots for the CH-53E). Unfortunately, unless materiel 
handling equipment or a large landing zone is available, large internal loads are time 
consuming to unload. In this analysis, only the small cargoes for the Sea Dragon RAPs are 
treated as internal payloads. All others are external loads. 4 Food, water, and ammunition 
are packaged on pallets, and fuel is transported in 500 gallon bladders, which the MV-22 
can carry two of at one time. 

Deception is a significant component of OMFTS (U.S. Marine Corps, 1996). In 
addition to the required sustainment and troop movement missions, MV-22s will also be 
used for decoy missions to deceive the enemy. This analysis looks at two cases: zero 
deception missions and one deception mission for every three actual missions. 

2. CH-53E 

Due to the small number (4-8) of CH-53Es and their relatively low operational 
availability (-60%), they would be dedicated to providing mobility' to the artillery battery 
and any emergent heavy lift requirements (e.g., recover}' of an LAV). Although the TBFDS. 



4 As a sensitivity analysis, supportability calculations were also performed using 
all sustainment except fuel transported internally. The results differred by less than 6%. 
While internally loaded cargo is preferred, it does not appear to be a driver for the forces 
analyzed. 



13 



CH-53E provides a forward refueling capability, it is not considered in this analysis due to 
the requirement for artillery movement. 

3. Daily Lift Requirements 

Tables 4 and 5 show the insertion and daily sustainment requirements for each of the 
force mixes. In the first three mixes, a minimum of two aircraft are required per mission. 
It is coincidental, but fortuitous, that the insertion and sustainment requirements are so 
similar. The extra two sorties required to insert the Air mix have a negligible effect on the 
results of the analysis.

IV. SUPPORTABILITY ANALYSIS 

A. DETERMINE MAXIMUM DISTANCE AT WHICH ASSETS CAN SATISFY 
SUPPORT REQUIREMENTS 

1. Equations 

This section describes the formulas used to calculate the maximum separation 
distance between units ashore and the sea-based sources of logistical support. The basic 
equation to determine this distance is 

D= c (1) 



where D = round trip distance in nautical miles, 
H = operational aircraft hours per day, 

T = total unusable time (on deck, loading, unloading, or refueling) in hours, 
V = aircraft speed in knots, 
S = number of sorties (Edwards 1993, 173). 

The following equations are used to take into account differing sortie types, times, 
and airspeeds: 

Number of available aircraft (N A ): 

N.-iNxAJ-N,, (2) 



where N = total number of a type of aircraft, 

A = average operational availability of aircraft type. 
N R = number of aircraft held in reserve. 



15 



Number of sorties required per aircraft per day (S): 



S= 7 E M D {RoundedUp) (3) 

"A 



where S, = total number of internal load sustainment sorties per day, 
S E = total number of external load sustainment sorties per day, 
S M = total number of troop movement sorties per day, 
S D = total number of deception sorties per day. 

(Rounding up prevents an aircraft from flying a fractional sortie.) 

Total number of sorties required per day (S T ): 

S T =S*N A (4) 

Extra time required for particular missions: 

Additional time per external load sortie (T E ), assuming one-way transport of 
external load: 



T - D - D - D -( l - l ) 

E 2V E 2Vj 2 V E V l ^ 



where D = round trip distance per sortie, 

V E = aircraft speed with an external load, 
V, = aircraft speed with an internal load.

Additional time per troop movement sortie (Tm): 



T =° M

where D M = average distance to transport troops.

where T D = Average on-deck time per sortie. 
Total operational aircraft hours per day (H T ). 



H T =H*N A 



(8) 



where H = operational hours per aircraft per day. 



To integrate the above equations, we start with the equation for round-trip distance 
per sortie (D): 






17 



Expanding T T gives 

{H T -(T D -S T )-{T^S M )-(T E -S E )yV I

Solving for D gives

18 



The final step is to solve for the effective one-way distance from ship to supported 
unit: 

D'=(^)*E (15) 

where E = Percentage of range that is effectively used. This allows for range 
reduction due to different ingress/egress routes, flight paths to avoid air defenses, and any 
other necessary maneuvering. 

2. Inputs 

This analysis uses the following as baseline inputs to the above equations, including 
some variations: 



• N A = 12 MV-22s. Present plans are to replace the CH-46E one-for-one on the 
LHDs and LHAs. 

• Aq= 0.85. This is the anticipated operational availability for the MV-22 (Morgan 
1996). 

• N R = 0, 2. At present, most MEU(SOC) operations do not hold back any aircraft 
for contingency missions, such as Tactical Recovery of Aircraft and Personnel 
(TRAP), MEDEVAC, or emergency extraction of ground combat units. A section 
(usually two aircraft) is designated as the TRAP section, but will go about normal 
operations until a mission requirement arises. The distances involved in OMFTS. 
the lack of ground transport or facilities for casualty evacuation and treatment, 
and the vulnerability of dispersed, small units provide some justification for a 
dedicated, on-call section for emergent missions. 5 This analysis looks at both 
cases, and 2. 

• S,, S E , and S M are self-explanatory. 

• S D = 0, (S ] +S E +S M )/3. OMFTS, especially the dispersed unit concept, advocates 
the use of deception and feints. This analysis looks at two cases. The first has no 
deception missions, as a baseline, and the second has one deception mission flown 
for every three real sustainment or troop movement sorties. 



5 In Vietnam. 8-10% of small reconnaissance patrols required some form of 
emergency extraction (West 1996). 

19 



• T D = 30 minutes. The expected operational refueling time for the MV-22 is 10-15 
minutes. External load pickup or release is approximately one minute. Internal 
cargo times vary, but can range from five to 30 minutes. Troop loading and 
unloading is approximately two minutes. We assume a notional 30 minute on- 
deck time for turn around. 

• H = eight hours per day per aircraft. This is a limit based primarily on the aircrew 
maximum flight hours, but also reflects aircraft maintenance requirements. 

• E = 80%. From interviews with Marine helicopter pilots, this figure was 
considered a fair estimate of the amount of range lost due to flight path routing. 

3. Baseline Results 

Table 6 summarizes the results for the different force mixes. The distance shown is 
the total separation distance possible between supporting ships and supported units. Three 
cases are looked at for each mix: using all available aircraft for troop movement and 
sustainment; holding two aircraft in reserve for TRAP or MEDEVAC; and adding deception 
missions while holding two aircraft in reserve. Note that these figures assume a permissive 
air defense environment. 



B. ASSESS EFFECTS OF AIRCRAFT ATTRITION ON MAXIMUM SUPPORT 
DISTANCE 

1. Approach 

The preceding section provides the maximum separation from sea base to ground 
units in a permissive air environment. To examine the impact of a non-permissive 
environment and the effects of aircraft attrition, a circulation model is used, shown in 
Figure 1.

2. Equations 

The following assumptions are made: 

• There is a fixed probability of an aircraft being shot down for every 100 NM 
flown over land, and the probability does not change with distance or time, i.e., 
the probability is the same crossing the beach as it is 200 NM inland, and is the 
same on D+l as it is on D+15. 

• Extra missions required to recover downed aircrew are not taken into account. 

• The MEU(SOC) operation will not fundamentally change as a result of aircraft 
losses. 

• Aircraft losses are binomially distributed (ie., independent and identically 
distributed) 6 with parameters n and/? 5 , where 

n = Total number of aircraft sorties per day, and 

p s = probability of shootdown per sortie. 



p s =l-(l-pf' (16) 



where p = Probability of shootdown per 1 00 NM traveled over land, and is 
assumed to be .01. 

D s = Average distance flown over land per sortie (100s of 
NM). Fractional values of D s are used when appropriate. 

The expected losses of all operating aircraft for the above equation each day are 

E[A ircraftLosses] =np s ( 1 7) 



6 Thus the effects of "hot spots*' of air defenses, operational attrition due to 
sandstorms, torrential rain, snowstorms and the like are disregarded, although in such 
cases p s tends to be higher than "on the average." 

22 



The expected losses are calculated for the end of each day, and the number of 
aircraft available for the following day is decreased by this amount. This may be a fractional 
number of aircraft because it is the expected number of aircraft remaining. The distance 
calculations in the previous section are recomputed based on this number and the new 
maximum separation distance determined. Figure 2 shows the decrease in operating 
distance as aircraft losses increase.

Table 7. Supportable ship/unit ranges in a non-permissive air environment 

4. An Example from the OMFTS Concept Paper 

The OMFTS concept paper gives an example of a hypothetical amphibious force 
conducting STOM against the eastern seaboard of the United States. Based on 24 hours of 
maneuvering at sea, the amphibious force requires the U.S. to defend the beaches from 
Charleston, South Carolina, to New Jersey. Richmond, Virginia, is selected as the objective 
and the force attacks the city directly from the sea (U.S. Marine Corps, 1996). 

From the preceding calculations, Richmond, at 95 NM inland, would require the 
ARG to stay within 45 NM of the Delaware/Maryland/Virginia coastline to conduct STOM, 
while Sea Dragon units could be inserted from a distance of more than 100 NM at sea. 
These distances apply only for a permissive air environment. In a non-permissive air 
environment, neither of the STOM force mixes could even be supported from the beach itself 
after one week of operations. The only force mix that could be sustained in this environment 
is the Sea Dragon mix, and then only if the units are supported by individual aircraft instead 



24 



of flights of two. To support this mix for an additional week would require the supporting 
ships to close from 1 00+ NM from the beach to within 43 NM. 



25 



26 



V. CONCLUSIONS 

A. SUMMARY OF RESULTS 

OMFTS, as envisioned, precludes surface resupply. Surface resupply over land 
requires secure land lines of communication and ground transportation. The distances 
involved require defense of these lines of communication, just as a beach CSS area would. 
CSS must be provided by air. In this thesis we have measured the outer limits of airborne 
CSS of a MEU(SOC) based on the airlift assets in a future MEU as it is now planned with 
twelve MV-22s. CH-53Es will be used for heavy lift support, including vehicles and 
artillery, in special circumstances. LCACs and AAAVs will be used for the delivery of 
equipment and Marines only - not sustainment. 

When OMFTS is conducted using traditional forces (without artillery permanently 
ashore, moving troops by air and surface means and sustaining troops. LAVs, and AAAVs), 
the envisioned amphibious ship standoff of 50+ NM is difficult if employing any deception 
missions or holding any aircraft in reserve, and is not possible in a non-permissive air 
environment. 

Shifting to a non-mechanized force does not ease the problem because of the 
increased airborne troop movement requirements. 

Shifting to the use of RAPs helps somewhat. However, the current practice of 
sending a two-aircraft section severely limits the possible range capability, because their 
payload is so light. If only one aircraft is sent to resupply or move a team, there is a huge 
increase in range. After 7 days of attrition (and the loss of 1/4 of the aircraft) it is still 
possible to conduct operations more than 200 NM from the ship. But, this decreases to 1 38 
NM by day 15. 

B. RECOMMENDATIONS 

Increased capability could be achieved by a number of different measures: 

• Increase ACE aircrews. This would allow more than eight hours per day aircraft 
utilization. However it is not certain how this would affect the operational 
availability of the aircraft or whether more severe maintenance requirements 
would result. 

27 



• Increase the number of MV-22s in the ACE. Making use of the spots on the LPD 
would allow 3 additional aircraft. Replacing the UH-ls with an additional MV-22 
would increase lift capacity, at the cost of not having a light helicopter capability. 
While not as valuable in OMFTS as the MY -22, the UH-1 is still a useful aircraft 
for sustained operations ashore or operations other than war. 

• If a MEU is to sustain OMFTS operations for more than a week, anticipate the 
need to replenish the ACE with additional MV-22s. 

• Small units could be supported at greater distances if one MV-22 was sent on 
each mission instead of the two-plane section that is the standard for helicopter 
operations today. The analysis shows that two-plane sections suffer a particularly 
onerous penalty in range because of their light load. 

This thesis considers an amphibious ready group operating independently of a carrier 
battle group (CVBG). A CVBG, whether part of a Naval Expeditionary Force or not, would: 

• Reduce attrition to MV-22s by providing escort or suppression of enemy air 
defenses. 

• Provide some additional lift or reserve lift capability if some MV-22s were 
assigned to the CV. 

To realize the full value of OMFTS, there must be a shift to more lethal forces with 
smaller logistical demands, or a sizable increase in airlift capability. To maintain a safe 
standoff from shore, maintain operational flexibility, and still support OMFTS, the Navy will 
need to push development of inshore combat tactics through means similar to those 
undertaken by the Commandant's Warfighting Lab. Influencing events ashore is more than 
being able to strike deep inland with precision weapons and aircraft. It is the ability to affect 
the campaign deep inland with forces on the ground. Until a lighter, more lethal Marine 
force is feasible, the Navy should plan on providing support to Marines from close to shore.
