From 2011 through 2015, DOD plans to spend over $336 billion to operate, maintain, modernize, and recapitalize its tactical air forces. Since DOD projects tactical aircraft inventory shortfalls over the next 15 years, it must effectively balance resources between an increasingly expensive Joint Strike Fighter program and the need to keep its legacy aircraft viable. GAO was asked to assess DOD's tactical aircraft requirements, the extent to which plans for upgrading and retiring legacy aircraft and acquiring new aircraft are likely to meet the requirements, and how changes in strategic plans and threat assessments have affected requirements. GAO analyzed tactical aircraft requirement and inventory data, key plans and threat assessments.
Matter for Congressional Consideration
|To ensure that DOD's future Aircraft Investment Plans are more complete, balanced, and comprehensive, Congress may wish to consider modifying the reporting requirements of future Plans to include not only acquisition costs for new procurements, but also investments for modernizing and sustaining legacy aircraft, including service life extension programs.||This matter for congressional consideration was initially drafted as a recommendation for executive action, and was included in the draft GAO report that was sent to DOD for official comment. In its comments, DOD noted that the annual Plans were directed by Congress and therefore any changes in the reporting parameters would have to be required by Congress. As a result the draft recommendation was converted to a matter for congressional consideration in the final GAO report. DOD's March 2012 Annual Aviation Inventory and Funding Plan discusses Air Force and Navy plans to invest in modernizing and sustaining legacy aircraft including service life extension programs, in addition to discussing investments in new aircraft development and procurement. DOD's previous Plans (2010 and 2011) focused on investments in new aircraft and did not discuss the considerable amount of funding needed to upgrade legacy systems. However, the March 2012 Plan, notes that the Air Force expects to invest in legacy fighter modernization and preferred munitions to help bridge the gap between legacy fighter platforms and the delayed F-35 Joint Strike Fighter program. It also states that the Air Force will conduct a service life extension program and capability upgrade for approximately 350 F-16 Block 40-52 aircraft beginning in fiscal year 2016. In addition to the Air Force, the Plan also addresses the Navy's expected investments in legacy aircraft. It states that the Navy is addressing the delays in the F-35 program with several management and investment measures: adding to the service life of approximately 150 legacy strike fighter aircraft (F/A-18A-D) and accelerating the transition of legacy F/A-18C squadrons to F/A-18E/F Super Hornets. The addition of this information in the 2012 Plan makes the plan more robust and provides greater transparency, which meets the intent of our recommendation.|
Recommendations for Executive Action
|Department of Defense||1. To address the uncertainty surrounding projected tactical aircraft shortfalls, the Secretary of Defense, working with the Secretaries of the Air Force and the Navy, should more clearly explain the department's requirements and the size and severity of anticipated tactical aircraft shortfalls, identify the key assumptions underlying shortfall projections, and identify alternatives and associated costs to mitigate the impact.|
|Department of Defense||2. The Secretary of Defense should more directly and clearly articulate how the complementary capabilities provided by unmanned aircraft, bombers, missiles, and other weapon systems are accounted for and quantified when calculating tactical aircraft requirements.|
|Department of Defense||3. To ensure that upcoming investment decisions are fully informed, the Secretary of Defense when reassessing tactical aircraft requirements and potential shortfalls should also complete a comprehensive tactical aircraft analysis that compares and contrasts the costs and benefits of extending the lives of legacy aircraft with the costs and benefits of procuring additional new aircraft including the F-22, JSF, F/A-18E/F, F-15E, and newest block F-16. This analysis should be provided to the Congress with the defense budget in February 2011 and include 1) an assessment of the technological and manufacturing feasibility of each option; 2) an evaluation of the pros and cons for each option in terms of combat effectiveness and desirability from the warfighter's perspective; and 3) identification of data sources and explanation of underlying assumptions; and identification of potential sources of funding for the various options including the deferment of JSF procurements into the future.|
