The original purpose of this paper was to explore the second and third order effects of this dramatic increase in the cost of jet fuel. However, as I began to study this issue I discovered that not enough scholarship has been done to examine just how closely jet fuel prices and the Marine Corps? TACAIR capability is linked. The Marine Corps has no appreciable way to minimize its reliance on jet fuel, and, in fact, is probably the most susceptible armed service to increased energy costs. The paper will determine that there is no appreciable way to improve the efficiency of tactical fighters and with a zero sum budget, any increase in the cost of jet fuel will result in fewer flight hours available. Since Marine Corps TACAIR is funded to just meet T - 2.0 requirements, any loss if flight hours will result in a loss of capability.
