billion to buy more existing tactical radios, such as the U.S. Marine Corps' Integrated, Intra-Squad Radio, the AN/PRC-117F and the AN/PRC-150. On June 22, 2007, the Joint Program Executive Office issued the first JTRS-Approved radio (not JTRS-Certified) production contract. It gave Harris Corporation $2.7 billion and Thales Communications Inc. $3.5 billion for first-year procurement and allowed the firms to compete for more parts of the five-year program. Harris could make up to $7 billion; Thales, $9 billion. In July 2008, the head of OSD AT&L conducted a 10-hour program review after costs continued to grow. Additionally, the JTRS Ground Mobile Radio program, originally funded at around $370 million, has now exceeded $1 billion despite reduced requirements. In 2012, after the first 100 General Dynamics Manpack radios showed "poor reliability", the US Army placed a $250 million order for nearly four thousand more of them. History CONDOR (Command and Control on the Move Network, Digital Over the Horizon Relay) During the Iraq War, the USMC developed their own system using commercial off the shelf technology, combining satcoms with wifi, that has worked ever since. Ground Mobile Radios GMR - formerly Cluster 1, run by the Army, was to equip Marine and Army ground vehicles, Air Force Tactical Air Control Parties (TACPs), and Army helicopters. Cluster 1 also included the development of a Wideband Networking Waveform (WNW), a next-generation Internet protocol (IP)-based waveform designed to allow mobile ad hoc networking (MANET). In 2005, the cluster was renamed Ground Mobile Radios (GMR) with the Air Force TACP and Army helicopter radios deleted. Handeheld Manpack & Small Form Fit HMS - formally Cluster 5, led by the Army, developed handheld, man-portable, and smaller radios. In 2006, it was renamed HMS, for Handheld, Manpack, and Small Form Factor. Airborne & Maritime/Fixed Station AMF - formerly Clusters 3 and 4: Cluster 3 aimed to develop a maritime / fixed radio. It was led by the Navy and grew out of the Navy's previous Digital Modular Radio program. Cluster 4, led by the Air Force, aimed to provide radios to Air Force and Navy fixed-wing aircraft and helicopters. In 2004, Clusters 3 and 4 were combined into the Airborne and Maritime / Fixed-Station program. In 2006, the Army helicopter radio was added to this cluster. In early 2008, JTRS AMF attained Milestone B after it received an additional $700 million. Cost estimates conducted by OSD's CAIG determined
