GAO reviewed the Navy's plans to upgrade both the propulsion and the guidance and control systems of the MK-48 Advanced Capability torpedo (ADCAP), focusing on the: (1) need for the propulsion system upgrade; and (2) appropriateness of approving low-rate initial production of the guidance and control system.<p/>GAO found that: (1) the Navy believes the $249 million ADCAP propulsion system upgrade will reduce the launching submarine's vulnerability in shallow water; (2) the propulsion upgrade will not improve ADCAP performance or reduce the submarine's vulnerability to enemy attack because of the short ranges at which submarines are likely to be detected in shallow water; (3) the upgrade is not needed, since ADCAP is already operational in shallow water; (4) the Navy did not establish a requirement to improve the propulsion system for use in open-ocean, deep water; and (5) low-rate initial production of the guidance and control system should not be approved until new software is developed and installed in mid-1998. https://www.govinfo.gov/content/pkg/GAOREPORTS-NSIAD-95-104/html/GAOREPORTS-NSIAD-95-104.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-NSIAD-95-104/pdf/GAOREPORTS-NSIAD-95-104.pdf GAO/NSIAD-95-104 https://www.govinfo.gov/app/details/GAOREPORTS-NSIAD-95-104 Letter Report GAO/NSIAD-95-104; Navy Torpedo Programs: MK-48 ADCAP Upgrades Not Adequately Justified; Submarines Advanced weapons systems Defense cost control Defense contingency planning Weapons research Research and development Computer software verification and validation Command and control systems Munitions Navy procurement Closed Cycle MK-48 Advanced Capability Propulsion System MK-48 Advanced Capability Torpedo MK-48 Advanced Development Torpedo Program ADCAP Torpedo Propulsion Upgrade Program Title 31 Section 720 31 U.S.C. 720
