The Navy recently completed contractor trials of the Knifefish unmanned underwater vehicle (UUV). Once operational, Knifefish will be capable of conducting autonomous anti-mine missions. Its payload would allow Knifefish to detect, classify, and identify mines at various depths, Seapower Magazine reported Oct. 26. The trials took place off the Massachusetts coast. They simulated hundreds of realistic missions, during which Knifefish would find and identify underwater targets. The Navy and Knifefish’s manufacturer, General Dynamics Corp., plan to put the vehicle through sea acceptance trials sometime next year. Once operational, Knifefish would be deployed from littoral combat ships and other Navy vessels, Seapower reported.
