U.S. GAO - Defense Acquisitions: Strategic Airlift Gap Has Been Addressed, but Tactical Airlift Plans Are Evolving as Key Issues Have Not Been Resolved

U.S. GAO - Defense Acquisitions: Strategic Airlift Gap Has Been Addressed, but Tactical Airlift Plans Are Evolving as Key Issues Have Not Been Resolved: "DOD has recently revamped airlift investments due to modernization cost increases and requirement changes. For strategic airlift, the number of C-5s that will be fully modernized were cut in half because of substantial reengining cost increases and C-17 quantities were increased from 180 to 213 aircraft. These twin changes resulted in a net cost increase of about$3 billion. Additional costs and force structure changes are possible pending decisions on C-5 retirements, other modifications, the potential need for more C-17s to meet tactical airlift needs, and the planned shutdown of C-17 production. For tactical airlift, substantial cost increases for modernizing C-130 avionics tripled unit costs, delayed its schedule, and resulted in almost 60 percent fewer aircraft being modernized. There have been large increases in the C-130J quantity to replace older C-130s, but modest increases in unit costs. The joint Army-Air Force C-27J program was recently transferred to the Air Force and quantities were cut from 78 to 38 aircraft, with an uncertain effect on the Army's airlift missions. The Army and Air Force must also resolve fundamental differences in operating requirements and employment strategy for the Joint Future Theater Lift (JFTL). DOD appears to have addressed its strategic airlift gap, but there is a potential future tactical airlift gap for moving medium weight equipment."
