Pursuant to a congressional request, GAO reviewed the Army's efforts to improve the engine recuperator used in the M1 Abrams tank, focusing on the: (1) Army's reasons for cancelling two contracts for alternate designs of the recuperator; (2) technical difficulties and cost overruns each contractor encountered; and (3) Army's current plans to develop an improved recuperator.
Recommendations for Executive Action
|Department of the Army||1. Before the Army makes a decision on whether to acquire the improved recuperator, the Secretary of the Army should collect and evaluate field data on the performance of the laser-welded recuperator on both the M1A1 and M1A2 tanks.|
|Department of the Army||2. Before the Army makes a decision on whether to acquire the improved recuperator, the Secretary of the Army should test the proposed improved recuperator on a fully equipped M1A2 tank to determine whether it has significantly greater durability than the current laser-welded recuperator.|
