The Army announced in June 2015 a Request for Proposal (RFP) for full-rate production of the HMS program. Goal was set for assessment in 2015-2016 and for full rate production in 2017.
JTRS is widely seen as one of the DoD's greatest acquisition failures, having spent $6B over 15 years without delivering a radio.
Overview
Launched with a Mission Needs Statement on August 21, 1997 and a subsequent Operational Requirements Document (ORD) on March 23, 1998 (which was revised several times), the original name was simply Joint Tactical Radio (JTR). This effort was led by the Joint Staff and was represented by all four Services. Each team member reported to their Service's chief information officer and reported back to the Joint Staff J6. The ORD started with 38 Threshold waveforms/radios and 4 Objective waveforms to support operations in three domain: Airborne, Maritime, and Ground Forces. Originally the JTR ORD do not address a software defined construct. The working group looked at the Navy's SPEAKeasy program as well as the USSOCOM sponsored Thales MultiBand Inter/Intra Team Radios. The JTR became Joint Tactical Radio System when the Navy took over as the acquisition executive agent. JTRS became a family of

framework that tells designers how hardware and software are to operate in harmony. It governs the structure and operation of the JTRS, enabling programmable radios to load waveforms, run applications, and be networked into an integrated system. A Core Framework, providing a standard operating environment, must be implemented on every hardware set. Interoperability among radio sets was increased because the same waveform software can be easily ported to all radios.

evolved from a loosely associated group of radio replacement programs to an integrated effort to network multiple weapon system platforms and forward combat units where it matters most – at the last tactical mile. In 2005, JTRS was restructured under the leadership of a Joint Program Executive Officer (JPEO) headquartered in San Diego, California. The JPEO JTRS provides an enterprise acquisition and management approach to successfully and efficiently develop, produce, integrate, test and field the JTRS networking capability.
The JTRS Enterprise was composed of five
ACAT 1D programs of record - Network Enterprise Domain (NED), Ground Mobile Radios (GMR), Handheld, Manpack, & Small Form Fit (HMS), Multifunctional Information Distribution System (MIDS) JTRS, and Airborne, Maritime Fixed/Station (AMF) and one ACAT III program - Handheld JTRS Enhanced Multi-Band Intra-Team Radio (JEM).

JTRS Ground Mobile Radios (GMR)
JTRS GMR are a key enabler of the DoD and Army Transformation and will provide critical communications capabilities across the full spectrum of Joint operations. Through software reconfiguration, JTRS GMR can emulate current force radios and operate new Internet Protocol (IP)-based networking waveforms offering increased data throughput utilizing self-forming, self-healing, and managed communication networks. The GMR route and retransmit functionality links various waveforms in different frequency bands to form one internetwork. GMR can scale from one to four channels supporting multiple security levels and effectively use the frequency spectrum within the 2 megahertz to 2 gigahertz frequency range. The radios are Software Communications Architecture compliant with increased bandwidth through future waveforms and are interoperable with 4+ current force radio systems and the JTRS family of radios.
Now that the GMR contract has been completed, the Army plans to leverage knowledge gained from the GMR Program in the upcoming Mid-Tier Networking Vehicular Radio solicitation.
JTRS Handheld, Manpack & Small Form Fit (HMS)
JTRS HMS is a materiel solution meeting the requirements of the Office of the Assistant Secretary of Defense for Networks and Information Integration/DoD Chief Information Officer for a Software Communications Architecture (SCA) compliant hardware system hosting SCA-compliant software waveforms (applications).
The JTRS HMS contract was structured to address Increment 1, consisting of Phases 1 and 2. Increment 1, Phase 1 was to develop the
AN/PRC-154 Rifleman Radio sets and embedded SFF-A (one channel), SFF-A (two channel) and SFF-D (one channel) versions. The AN/PRC-154 Rifleman Radio sets and SFFs were to utilize the Soldier Radio Waveform (SRW) in a sensitive but unclassified environment (Type 2). In order to mitigate program waveform porting and integration challenges, the SRW application, which is managed by the JTRS Network Enterprise Domain, was developed on a Waveform Development Environment with HMS as the lead platform for porting.
Increment 1, Phase 2 was to develop the two channel manpack, two channel handheld, and embedded SFF-B, versions that are all Type 1 compliant for use in a classified environment. Waveforms on the phased sets include Ultra High Frequency (UHF) Satellite Communications, Soldier Radio Waveform (SRW), High Frequency (HF), Enhanced Position Location and Reporting System (EPLRS), Mobile-User Objective System (MUOS), and Single Channel Ground to Air Radio System (SINCGARS).
Multifunctional Information Distribution System (MIDS) JTRS
MIDS is a secure, scalable, modular, wireless, and jam-resistant digital information system currently providing Tactical Air Navigation (TACAN), Link-16, and J-Voice to airborne, ground, and maritime joint and coalition warfighting platforms. MIDS provides real-time and low-cost information and situational awareness via digital and voice, communications within the Joint Tactical Radio System (JTRS) Enterprise. The MIDS Program includes MIDS-LVT and the MIDS JTRS Terminal. MIDS-LVT is in full rate production and MIDS JTRS is in evolutionary development and limited production. MIDS JTRS is a “form fit function” replacement for MIDS–LVT and adds three additional channels for JTRS waveforms as required by joint and coalition warfighter.
JTRS Airborne & Maritime/Fixed Station (AMF)
AMF will provide a four-channel, full duplex, software-defined radio integrated into airborne, shipboard, and fixed-station platforms, enabling maritime and airborne forces to communicate seamlessly and with greater efficiency through implementation of five initial waveforms (i.e., Ultra-High Frequency Satellite Communications, Mobile User Objective System, Wideband Network Waveform, Soldier Radio Waveform, and Link 16) providing data, voice, and networking capabilities. JTRS AMF is software-reprogrammable, multi-band/multi-mode capable, mobile ad hoc network capable, and provides simultaneous voice, data, and video communications. The system is flexible enough to provide point-to-point and netted voice and data, whether it is between Service Command Centers, Shipboard Command Centers, Joint Operations Centers or other functional centers (e.g., intelligence, logistics, etc.). AMF will assist U.S. Armed Forces in the conduct of prompt, sustained, and synchronized operations, allowing warfighters the freedom to achieve information dominance in all domains; land, sea, air, space, and information.

Problems and restructuring
In March 2005, the JTRS program was restructured to add a Joint Program Executive Office, a unified management structure to coordinate development of the four radio versions.
In March 2006, the JPEO recommended changing the management structure, reducing the scope of the project, extending the deadline, and adding money. The JPEO's recommendations were accepted.
The program is focusing on the toughest part: transformational networking. The JTRS radio was to be a telephone, computer and router in one box that can transmit from 2 MHz to 2 GHz.

Wideband Networking Waveform (WNW), a next-generation 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 that the original amount, just over $500 million, was too little. On March 28, 2008, Lockheed Martin announced that the JTRS Joint Program Executive Office picked it to design and provide tactical communications and networking gear for the Air Force, Army, Navy and other users. The initial System Development and Demonstration (SDD) contract value is $766 million. Subcontractors will include BAE Systems, General Dynamics, Northrop Grumman, and Raytheon. Work will be conducted at Scottsdale, Ariz.; San Diego, Calif.; Tampa, Fla.; Fort Wayne, Ind.; Gaithersburg, Md.; St. Paul, Minn.; Wayne, N.J.; Charleston, S.C.; and Chantilly and Reston, Va.
* MIDS JTRS - In 2006, the JTRS program took over the effort to improve the Multifunctional Information Distribution System Low Volume Terminal (MIDS-LVT) design, which was developed by a 5-nation consortium in the 1990s. This program was renamed MIDS-JTRS and also experienced cost growth and delays.
*Special Radios
**JEM. - formally Cluster 2, was renamed the JTRS JEM program, adds JTRS capability to the existing handheld
AN/PRC-148
