GAO provided information regarding the Air Force's progress in achieving and sustaining full operational capability for the Peacekeeper missile force.GAO found that the Air Force: (1) delayed its plans to start full operational capability testing, citing congressional directions, basing mode redirections, gaps between developmental and operational flight testing, and production delays; (2) believe...
Space Shuttle: NASA's Major Changes to Flight Hardware
NSIAD-88-173FS: Published: Jun 27, 1988. Publicly Released: Jul 6, 1988.
In response to a congressional request, GAO identified the types of changes that the National Aeronautics and Space Administration (NASA) made to the space shuttle's flight hardware, focusing on enhancements: (1) it made to flight hardware; (2) that cost at least $5 million each; and (3) it implemented from 1981 through 1987.GAO found that NASA: (1) made 56 changes to the space shuttle; (2) initia...

In response to a congressional request, GAO provided information on the space shuttle program's Vandenberg launch site (VLS) in California, specifically: (1) the Air Force's cost estimates for various VLS operating levels and VLS technical issues identified in a congressional report; (2) plans for manned spaceflight from VLS; (3) the President's rationale for replacing the space shuttle Challenger...
Carrier Landing Systems: Replacement of the Navy's Automatic Landing System May Be Premature
NSIAD-86-214BR: Published: Sep 22, 1986. Publicly Released: Oct 2, 1986.
Pursuant to a congressional request, GAO reviewed the Navy's plan to replace the AN/SPN-42 automatic carrier landing system (ACLS) with the AN/SPN-46 ACLS. ACLS allows pilots to control aircraft during their final approach and landing aboard a carrier.GAO found that: (1) the Navy has not been able to achieve its automatic landing goal of 70 percent for ACLS due to problems with aircraft-related su...
Planning for Navy Shore Facilities: Improvements Possible
NSIAD-85-6: Published: Nov 5, 1984. Publicly Released: Nov 5, 1984.
GAO reviewed selected Navy activities' use of the Shore Facilities Planning System (SFPS) to determine whether the activities' use of the system resulted in accurate determinations of facility requirements and optimum use of existing facilities.GAO found a number of instances where the use of SFPS by activities resulted in inaccurate facility requirements causing the construction of some unneeded,...
Department of Defense's Space Laser Program Plan--Status and Issues
NSIAD-84-132: Published: Aug 9, 1984. Publicly Released: Aug 9, 1984.
GAO reviewed the Department of Defense's (D0D) Space Laser Program Plan to evaluate the plan's progress and potential.GAO found that: (1) the 6-year, $908.3 million effort presented in 1982 increased to 7 years and $1,558.3 million in 1983; and (2) DOD was not able to adequately monitor the plan's status because the management and funding structure is too diffuse to be effective. Further, no singl...
