Vehicular SINCGARS Radios
The SINCGARS familiy of tactical radios has a range of optional configurations to provide for multiservice requirements. This page briefly describes some of the available models for installation in vehicles. The differences are described, using material from FM 44-48, Tactics, Techniques, and Procedures For The Sensor Platoon, Appendix F, Communications Planning and Troubleshooting.

Vehicular SINCGARS AN/VRC-87
The AN/VRC-87 is a short-range, vehicle-mounted radio set with a solid-state, securable transceiver intended for VHF-FM tactical operations. The AN/VRC-87 is used where the communications range is normally 8 kilometers or less. The configuration is used by the ADA platoon, headquarters battery, and similar applications. The capabilities are the same as the AN/PRC-119 manpack radio, except the AN/VRC-87 cannot be used in a dismounted role. The AN/VRC-87 replaces the AN/VRC-64 radio. In the photo to the left, John Crosby, a civilian contractor from Fayetteville, NC, installs a SINCGARS mount in a Wisconsin Army National Guard HMMWV.
Vehicular SINCGARS AN/VRC-88
The AN/VRC-88 is a vehicle-mounted radio that has a manpack antenna, and a battery case as additional components. The radio can be removed from the vehicle, and by installing the antenna and battery case, can be reconfigured as an AN/PRC-119 manpack radio. The AN/VRC-88 has a 4-kilometer range and may be operated from a vehicle or in a dismounted configuration. It provides more channels, reduces operator burden, and increases equipment reliability. The AN/VRC-88 is used by soldiers to communicate from vehicles or from dismounted positions. It is the replacement for the AN/GRC-160 radio.
Vehicular SINCGARS AN/VRC-89
The AN/VRC-89 is a vehicle-mounted, dual-configuration radio consisting of one short-range and one long-range, solid-state, securable transceiver intended for VHF-FM tactical operations. The AN/VRC-89 provides long-range (up to 35 kilometers) and short-range (up to 8 kilometers) operation in two nets simultaneously. The AN/VRC-89 is a dual-radio configuration mounted on a single vehicular mount. It replaces existing AN/VRC-47 configurations, as well as separate configurations of AN/VRC-64 or AN/VRC-46 in a single vehicle. The AN/VRC-89 is basically two vehicular-mounted, short-range radio sets with an added power amplifier that provides one of the radio sets with a long-range communications capability up to 35 kilometers.
Vehicular SINCGARS AN/VRC-90
The AN/VRC-90 is a long-range, vehicle-mounted radio set with a securable transceiver intended for VHF-FM tactical operations. The AN/VRC-90 is used where the communications range must normally operate over long distances (up to 35 kilometers). The AN/ VRC-90 vehicular configuration is used by individuals and crews that require continuous, long-range communications in a net. The radio configuration is used throughout the Army at all echelons from corps through platoon. The AN/VRC-90 replaces the AN/VRC-46 radio.
Vehicular SINCGARS AN/VRC-91
The AN/VRC-91 is a vehicle-mounted, dual-radio configuration consisting of one long-range and one short-range dismountable, solid-state, securable transceiver intended for VHF-FM tactical operations. The AN/VRC-91 provides long-range (up to 35 kilometers) and short-range dismountable (up to 8 kilometers) operation in two nets simultaneously. The AN/VRC-91 vehicular, long-range/short-range man-pack configuration provides maximum flexibility. The AN/VRC-91 basically combines the features of the AN/VRC-88 and AN/VRC-90 into a single-vehicle installation. The AN/VRC-91 replaces the AN/ GRC-160 radio when teamed with the AN/VRC-46 in a single vehicle.
Vehicular SINCGARS AN/VRC-92
The AN/VRC-92 is a vehicle-mounted, dual-radio configuration consisting of two long-range, solid-state, securable transceivers intended for VHF-FM tactical operations. In the photo to the right, a SINCGARS retrans has been installed in an S-250 shelter, well-equipped with an M-249 SAW, Global Positioning System, AN/GRC-193, AN/PSC-5, two AN/VRC-92s, AN/PRC-119, two power supplies and a multimeter.
The AN/VRC-92 also has an automatic retransmission capability. It is used to meet dual, long-range (up to 35 kilometers) communications requirements. The AN/VRC-92 is also used for VHF-FM retransmission operations. It is basically a AN/VRC-88 with an additional power amplifier mount to provide communications range up to 35 kilometers to the second radio system. This configuration replaces two separate AN/VRC-46 radios in a single vehicle and the AN/VRC-49 radio. Because of the automatic retransmission capability found in each SINCGARS, all AN/VRC-92 configurations are capable of automatic transmission.
Vehicular SINCGARS AN/MRC-145
The AN/MRC-145 is a vehicular-mounted SINCGARS with power amplifier and two radios per vehicle. It is used by the Marine Corps in a similar role to the dual radio AN/VRC-91 or -92 Army SINCGARS.
