General Dynamics Completes Successful Critical Design Review for Knifefish Mine Countermeasure Unmanned Undersea Vehicle

FAIRFAX, Va. - GeneralDynamics Advanced Information Systems has successfully completed the critical designreview for Knifefish, the surface-mine countermeasure unmanned undersea vehicle(SMCM UUV), one month ahead of schedule. The General Dynamics team will nowbegin the development of the system hardware and software to integrate theapproved design via the fabrication of three engineering development modules. Knifefishis an essential component of the Littoral Combat Ship (LCS) mine countermeasure(MCM) mission package, providing U.S. Navy commanders and sailors with enhancedmine-hunting capabilities.

Expected to attain initial operational capability in 2017, Knifefishis the first heavyweight-class mainstream mine countermeasure (MCM) UUV that willaddress the Navy's need to reliably detect and classify mines resting on theseafloor and buried mines in high-clutter environments and areas with potentialfor mine burial. Knifefish also gathers environmental data to provideintelligence support for other mine warfare systems.

Knifefish will help greatly reduce risk to Navy personneland ships by operating in minefields as an off-board sensor, while the hostship stays outside the minefield boundaries. The modular, open Knifefish hasbeen designed to integrate with both variants of LCS via the common LCSinterface control document.

'Knifefish is designed to be compatible with an openarchitecture platform, ensuring that the Navy's mission systems will keep pacewith technology and continue to evolve to meet current and future mission

requirements,' said Lou Von Thaer, president of GeneralDynamics Advanced Information Systems. 'The ease of the 'plug and play' integrationwith ship systems and mission modules allows for platform flexibility and quickreconfiguration of the whole mission package in response to the dynamicrequirements the fleet will encounter day to day.'

The U.S. Navy's Naval Sea SystemsCommand (NAVSEA) awarded General Dynamics Advanced Information Systems acontract to design and build Knifefish in September 2011. The General DynamicsAdvanced Information Systems team on the Knifefish program includes BluefinRobotics (Quincy, Mass.), Ultra Electronic Ocean Systems (Braintree, Mass.),Oceaneering International, Inc. (Houston, Texas), Metron (Reston, Va.), AppliedResearch Laboratory at Penn State University (State College, Pa.), 3 Phoenix(Hanover, Md.), General Dynamics Information Technology (Fairfax, Va.) and ASRCResearch Technology Solutions (Greenbelt, Md.).
