Electronic Warfare: Laser Warning System Production Should Be Limited
NSIAD-93-14: Published: Jan 25, 1993. Publicly Released: Jan 25, 1993.
GAO evaluated the Army's test program for the AVR-2 laser warning system and a newly modified version designated as AVR-2A, focusing on whether the testing justified the systems' full-rate production status.GAO found that: (1) the performance capability of AVR-2 and AVR-2A has not been proven, since neither system has been subjected to operational tests to ensure satisfactory performance; (2) the...
Weapons Acquisition: A Rare Opportunity for Lasting Change
NSIAD-93-15: Published: Dec 1, 1992. Publicly Released: Dec 1, 1992.
GAO reviewed the Department of Defense's (DOD) major weapons acquisition issues, focusing on the cultural aspects of acquisition problems.GAO found that: (1) despite attempts to improve the acquisition process, weapons still cost more, take longer to field, often encounter performance problems, and are difficult to produce or support; (2) cost growth, schedule delays, and performance shortfalls ca...
High Risk Series: Defense Weapons Systems Acquisition
HR-93-7: Published: Dec 1, 1992. Publicly Released: Dec 1, 1992.
GAO reviewed the Department of Defense's (DOD) annual expenditure of billions of dollars to acquire new weapons systems, focusing on DOD determination, planning, budgeting, and acquisition of major weapons requirements.GAO found that: (1) while the services conduct considerable analyses to justify major acquisitions, these analyses were narrowly focused, and did not fully consider alternative solu...
Strategic Defense Initiative: Some Claims Overstated for Early Flight Tests of Interceptors
NSIAD-92-282: Published: Sep 8, 1992. Publicly Released: Sep 16, 1992.
Pursuant to a congressional request, GAO provided information on the accuracy of Strategic Defense Initiative Organization's (SDIO) claims concerning flight test results.GAO found that the: (1) Kinetic Kill Vehicle Integrated Technology Experiment (KITE) utilizes a shroud to protect the optical window sensor at the missile's front; (2) Army Strategic Defense Command inaccurately claimed that the K...
Navy Torpedo Program: MK-48 ADCAP Propulsion System Upgrade Not Needed
NSIAD-92-191: Published: Sep 10, 1992. Publicly Released: Sep 10, 1992.
GAO reviewed the Navy's MK-48 Advanced Capability (ADCAP) torpedo propulsion system upgrade program, focusing on whether the: (1) Navy needs an upgraded propulsion system; (2) upgrade would meet Navy noise reduction requirements; and (3) Navy is conducting research in alternative noise reduction technology.GAO found that: (1) the current system would meet the Navy's requirements for the SSN-21 Sea...
Arms Control: Improved Coordination of Arms Control Research Needed
NSIAD-92-149: Published: Apr 14, 1992. Publicly Released: May 14, 1992.
Pursuant to a congressional request, GAO reviewed the effectiveness of coordination of research being performed to verify arms control agreements between the United States and the former Soviet Union, focusing on: (1) how the executive branch decides on the research needed to provide verification instruments to on-site inspectors; (2) whether research and development mechanisms exist to ensure tha...
Weapons Codevelopment: U.S. National Issues in the MLRS Terminal Guidance Warhead Program
NSIAD-92-55: Published: Apr 21, 1992. Publicly Released: Apr 21, 1992.
GAO reviewed how the Army's Multiple Launch Rocket System (MLRS) Terminal Guidance Warhead (TGW) Program protects U.S. interests.GAO found that: (1) although the United States is to pay 40 percent of the MLRS TGW development cost and France, Germany, and the United Kingdom are each to pay 20 percent, the Memorandum of Understanding (MOU) limited the U.S. development work share under the prime cont...
Strategic Defense Initiative: Estimates of Brilliant Pebbles' Effectiveness Are Based on Many Unproven Assumptions
NSIAD-92-91: Published: Mar 27, 1992. Publicly Released: Mar 27, 1992.
Pursuant to a congressional request, GAO reviewed the Strategic Defense Initiative Organization's (SDIO) assessment of the effectiveness of Brilliant Pebbles, a proposed space-based weapon for the Global Protection Against Limited Strikes (GPALS) Strategic Defense System.GAO found that: (1) as of December 1991, SDIO had not evaluated through computer simulations Brilliant Pebbles' performance agai...
Electronic Warfare: DOD Did Not Meet Test Criteria Before Production of the Airborne Self-Protection Jammer
T-NSIAD-92-22: Published: Mar 25, 1992. Publicly Released: Mar 25, 1992.
GAO discussed the Navy's Airborne Self-Protection Jammer (ASPJ) Program, focusing on the Department of Defense's (DOD) compliance with recommendations allowing further ASPJ procurement only if it meets its reliability growth criterion. GAO noted that: (1) the ASPJ reliability growth criterion specifies that the system must achieve a minimum mean time of 75 hours between failures; (2) ASPJ reliabil...
