Acquisition of the Navy Surface Mine Countermeasure Unmanned Undersea Vehicle (Knifefish) Needs Improvement [open pdf - 4MB]
"We determined whether the Navy effectively established requirements and planned testing to support procuring the Surface Mine Countermeasure Unmanned Undersea Vehicle (Knifefish). The Knifefish is a self-propelled, untethered, autonomous underwater vehicle designed to find underwater mines. The Knifefish is capable of operating independently in shallow ocean water, and is launched and recovered from the Littoral Combat Ship-a fast, agile ship designed for operations in environments near the shoreline. The Navy did not effectively establish capability requirements and plan and execute testing to procure the Knifefish. Specifically, the Knifefish requirements developer (Expeditionary Warfare Division, N95) did not fully define requirements to support the communication interface and launch and recovery operations between the Knifefish system and the Littoral Combat Ship."
