The Marine Corps Operational Test and Evaluation Activity (MCOTEA), the independent test agency for the Marines, conducted initial operational testing and evaluation of the EFSS from May to July 2007, and reported in September 2007, among other things, that it experienced several safety, performance, reliability, and mechanical problems. We briefed you on these and other issues related to the EFSS in September 2007. Subsequently, at your request, the Marine Corps delayed full-rate production of the EFSS until after GAO reported on the system. In December 2007, we issued our report,' which described the system's safety, performance, reliability, and mechanical problems. MCOTEA retested the system in February and March 2008, focusing on determining whether the problems identified in 2007 were resolved. It reported its analysis of the test results in May 2008. In October 2008, you asked us to provide you with a brief assessment of the Marine Corps' conclusions regarding whether the concerns we reported have been addressed. To do so, we reviewed MCOTEA's May 2008 Independent Evaluation Report from the EFSS' Follow-on Operational Test and Evaluation as well as documentation of the system's insensitive munition certification, and compared the results with the concerns we reported in 2007. We also reviewed documentation of EFSS' full-rate production decision. We interviewed EFSS program officials, a Marine Corps Combat Development Command official, and the MCOTEA official who oversaw EFSS testing to obtain their 1 GAO, Defense Acquisitions: Status of the Expeditionary Fire Support System, GAO-08-33IR (Washington, D.C., Dec. 21, 2007). 2 Certification that a munition will not detonate under any condition other than its intended mission.
