Joint Tactical Radio System (JTRS) Cluster 3
Joint Tactical Radio System (JTRS) Maritime/Fixed

The JTRS program was developing software-defined radios that would interoperate with existing radios and also increase communications and networking capabilities. A Joint Program Executive Office provided a central acquisition authority and balanced acquisition actions across the services. Program/product offices were developing radio hardware and software for users with similar requirements. The original Cluster 3 (Maritime/Fixed domain) was the primary responsibility of the Navy. The Navy was responsible for the development and fielding of the product. These radios were to be used on US Navy ships and in fixed base stations by all services.

As of an August 2003 GAO report on the risks associated with the overall program, Cluster 3 was reported as having a planned Milestone B in first quarter FY04, Milestone C in fourth quarter FY06, followed by a full-rate production decision in the first quarter of FY09.

In September 2003 the Office of Naval Reserach reported that HYPRES Inc, was building new digital receivers. Deborah Van Vechten, program officer in ONR's Electronics division, said that this company would deliver a demonstration receiver that simultaneously "digitizes" all the signals in the most critical over-the-horizon military communications bands (HF and VHF) and used a technique called software-controlled digital filtering to select the signals to output. HYPRES at the time had already teamed with Boeing, winner of the JTRS "Cluster 1" contract for the Army. The company was reported as hoping to get selected for Cluster 3, the maritime JTRS, which was then managed by the Space and Naval Warfare Systems Command.

Cluster 3 was outlined in the US Navy's 2004 edition of Vision, Precense, Power, a Program Guide to the US Navy as a Navy-lead ACAT 1D program with program initiation expected in the second quarter FY04.

As part of restructuring, Cluster 4 was merged with Cluster 3, forming a joint USAF/USN program office for what was then renamed JTRS Airborne, Maritime-Fixed Station (JTRS AMF).
