Pursuant to a congressional request, GAO reviewed the evolution of the Navy's AN/BSY-1 Combat System, focusing on: (1) the extent to which AN/BSY-1 program requirements differ from those established for the Submarine Advanced Combat System (SUBACS) program; (2) status and results of AN/BSY-1 developmental testing and evaluation; and (3) impact of combat system development problems on the Los Angeles class nuclear attack submarine (SSN-688) construction program.

GAO found that: (1) in 1980, the Navy began developing SUBACS for SSN-688, but when SUBACS experienced difficulties, the Navy divided it into AN/BSY-1 for SSN-688 and AN/BSY-2 for the Seawolf class nuclear attack submarine; (2) due to an accelerated ship installation schedule, AN/BSY-1 is less capable than SUBACS, since it does not distribute data as quickly, does not have as many data processing units, and lacks redundancy and expansion space to overcome malfunctions; (3) in October 1990, the Navy completed developmental testing and evaluation of AN/BSY-1 and concluded that, in most areas, it met or exceeded its expected performance; (4) AN/BSY-1 performance varied from the expected performance in such areas as sonar variance, longevity, firing system variance, and problem identification variances, but the Navy planned to correct those performance deficiencies; and (5) SUBACS and AN/BSY-1 design and development problems increased the Navy's costs by about $218 million and delayed SSN-688 completion by an average of 19 months.
