Military Aircraft: Considerations in Reviewing the Air Force Proposal to Lease Aerial Refueling Aircraft
Abstract
While numerous military aircraft provide refueling services, the bulk of U.S. refueling capability lies in the Air Force fleet of 59 KC-10 and 543 KC-135 aircraft. These are large, long-range aircraft that have counterparts in the commercial airlines, but which have been modified to turn them into tankers. The KC-10 is based on the DC-10 aircraft, and the KC-135 is similar to the Boeing-707 airliner. Because of their large numbers, the KC-135s are the mainstay of the refueling fleet, and successfully carrying out the refueling mission depends on the continued performance of the KC-135s. Thus, recapitalizing this fleet of KC-135s will be crucial to maintaining aerial refueling capability, and it will be a very expensive undertaking. There are two basic versions of the KC-135 aircraft, designated the KC-135E and KC-135R. The R model aircraft have been re-fitted with modern engines and other upgrades that give them an advantage over the E models. The E-model aircraft on average are about 2 years older than the R models, and the R models provide more than 20 percent greater refueling capacity per aircraft. The E models are located in the Air National Guard and Air Force Reserve. Active forces have only R models. Over half the KC-135 fleet is located in the reserve components. The rest of the DOD refueling fleet consists of Air Force HC- and MC-130 aircraft used by special operations forces, Marine Corps KC-130 aircraft, and Navy F-18 and S-3 aircraft. However, the bulk of refueling for Marine and Navy aircraft comes from the Air Force KC-10s and KC-135s. These aircraft are capable of refueling Air Force and Navy/Marine aircraft, as well as some allied aircraft, although there are differences in the way the KC-10s and KC-135s are equipped to do this.
