The company said in a statement last week that the new contract could come to $140 million in value. The order is to "develop and integrate the maritime and fixed-site joint tactical radio capabilities and provide information assurance services" for the Lockheed Martin Airborne, Maritime and Fixed Site Joint Tactical Radio System project, General Dynamics said. The AMF JTSR is designed to function as a key component of the U.S. tactical Global Information Grid and to guarantee safe data, voice and video for U.S. mobile tactical platforms operating with joint forces, aircraft and maritime assets interacting with U.S. bases around the globe.

General Dynamic said its operations on the project will be carried out in Scottsdale, Ariz., by General Dynamics' C4 Systems business unit.

General Dynamics said it would also organize and carry out qualification testing for the joint tactical radios for Maritime and Fixed Sites. This would cover radio set certification, waveform integration and deployment of fixed-site communication equipment, the company said.

General Dynamics said it was also spearheading information assurance development for the mobile networked communications for the Lockheed Martin AMF JTRS project. This would involve producing Type 1 INFOSEC modules for airborne, maritime and fixed-site radios; and getting certification and accreditation for the AMF JTRS radios and system, as well as preparing the High Assurance Internet Protocol Encryptor services to receive classified data, the company said.

General Dynamics said it also functioned as prime contractor for the JTRS Handheld, Manpack and Small Form Fit program launched by the U.S. Army in 2004. The JTRS HMS system is due to undergo limited user tests before the end of 2008.
