The United States Air Force, Navy, and Marine Corps have long maintained tactical fighter forces that provide capabilities for air-to-air combat and air-to-ground attack. The three services are in the process of replacing the bulk of today's fighter aircraft, most of which were purchased in the 1980s, with new F/A-18E/F, F-22, and F-35 (Joint Strike Fighter) aircraft. Although current procurement plans call for the purchase of about 2,500 aircraft over the next 25 years, the services are projecting that those purchases will not keep pace with the need to retire today's aircraft as they reach the limit of their service life. The study also compares the advantages, disadvantages, and costs of seven alternative approaches that DoD might adopt to modernize its fighter forces -- three that satisfy today's inventory requirements, two that maintain aggregate weapons capacity with fewer aircraft, and two that replace portions of the fighter force with longer-range aircraft. In keeping with CBO's mandate to provide objective, impartial analysis, this study makes no recommendations.
"The Congress created the Arsenal Support Program Initiative (ASPI) to help maintain the functional capabilities of the Army's three manufacturing arsenals, which are located in Rock Island, Illinois, Watervliet, New York, and Pine Bluff, Arkansas. A primary goal of the program is to enable commercial firms to lease vacant space at the arsenals once that space has been renovated, thereby encouraging collaboration between the Army and commercial firms as well as reducing the costs the government incurs to operate and maintain the arsenal facilities. Since the ASPI's inception, a number of commercial tenants have leased unused property at the arsenals; however, the financial benefits that the program has generated for the government have proved to be small relative to the program's funding. In response to a directive from the Congress, the Congressional Budget Office (CBO) conducted a 'business case' analysis of the ASPI, examining the program's costs, return on investment, and economic impact. In keeping with CBO's mandate to provide objective, nonpartisan analysis, this report makes no recommendations."--Preface.
This study "examines the Navy's missions, its modernization plans, and the budgetary implications of supporting the service's current and planned fleets through 2020. It also looks at four alternative force structures that the Navy might be able to sustain at roughly its current funding level of 90 billion ... Eric J. Labs of CBO's National Security Division wrote the study under the general supervision of Christopher Jehn and R. William Thomas"--Pref.
"The United States Navy and Marine Corps operate a fleet of tactical fighter aircraft that provide air-to-air and air-to-ground combat capabilities. Although current procurement plans call for the purchase of about 700 new fighter aircraft over the next 15 years, the Department of the Navy is projecting that purchases planned for the next 5 to 10 years will be unable to keep pace with the retirement of today's F/A-18A-D Hornets as they reach the limit of their service life. This Congressional Budget Office (CBO) report---prepared as directed by the House Armed Services Committee's Report on the National Defense Authorization Act for Fiscal Year 2010 (H. Rept. 111-166)--compares several alternatives for maintaining the Navy's and Marine Corps' fighter inventory levels. The alternatives include different combinations of extending the service life of Hornets and purchasing new aircraft in addition to those already planned. In keeping with CBO's mandate to provide objective, impartial analysis, this report makes no recommendations"--Preface.
Currently available launch vehicles have the capacity to lift payloads into low earth orbit that weigh up to about 25 metric tons, which is the requirement for almost all of the commercial and governmental payloads expected to be launched into orbit over the next 10 to 15 years. However, the launch vehicles needed to support the return of humans to the moon, which has been called for under the Bush Administration's Vision for Space Exploration, may be required to lift payloads into orbit that weigh in excess of 100 metric tons and, as a result, may constitute a unique demand for launch services. What alternatives might be pursued to develop and procure the type of launch vehicles necessary for conducting manned lunar missions, and how much would those alternatives cost. This Congressional Budget Office (CBO) study-prepared at the request of the Ranking Member of the House Budget Committee-examines those questions. The analysis presents six alternative programs for developing launchers and estimates their costs under the assumption that manned lunar missions will commence in either 2018 or 2020. In keeping with CBO's mandate to provide impartial analysis, the study makes no recommendations.
