Defense Acquisitions: Status of the Expeditionary Fire Support System
Abstract
The EFSS met all of its key performance parameters and 13 of 14 critical requirements during the operational test. The only critical requirement not met was the mortars maximum rate of fire. The EFSS also experienced several safety, performance and reliability problems during testing, which led the test activity to conclude that the EFSS was operationally effective with limitations and operationally suitable with limitations. Testing identified " safety issues, including potential injury to a crew member riding in the ammunition support vehicle s rear seat; " performance issues, including how fast the weapon can be fired and moved, and the vehicle's equipment-carrying capacity; and " reliability issues, including mechanical failures, such as the inability to sufficiently cool the engine and vehicle-starting problems at altitude. Also, because of delays getting test assets, cold weather testing that was planned for February 2007 was not conducted. Recently, the program office discovered a problem with the primer for the propellant section of the mortar s ammunition. If this problem is not resolved in time, the cold weather testing could be missed again.
