"The Omega tanker flying contract is administered by NAVAIRSYSCOM PMA 207.5. The tanker is funded for its flying hours through PMA 207.5 to support Navy and Marine Corps Aviation. Thus, there is no direct cost to the military units for requesting and flying with Omega. All flights are approved by a government representative. Omega Aerial Refueling Services, Inc. receives compensation per flight hour flown, regardless of how much fuel is offloaded. Fuel offloaded by the tanker is allocated and charged to the appropriate squadron in the same way that fuel received anywhere is allocated and charged, just like fuel in the hot pits, at transient operating bases, at transient government-approved civilian FBO's, or from USAF tankers. The cost is the same as government fuel anywhere. As part of the contract, Omega does not pay for its fuel, but rather uses the same government credit card that military units use to pay for fuel. Omega must also use government-approved sources for fuel."
