The UH-1Y Venom (also called Super Huey) is a twin-engine medium size utility helicopter, part of the United States Marine Corps' H-1 upgrade program. This helicopter is design and manufactured by the Company Bell. The UH-1Y is currently in full-rate production to replace the USMC's aging fleet of UH-1N Twin Huey light utility helicopters first introduced in the early 1970s. The UH-1Y was to have been remanufactured from UH-1Ns, but in 2005 it was approved for the aircraft to be built as new. The UH-1Y share a common tail boom, engines, rotor system, drive train, avionics architecture, software, controls and displays with AH-1Z for over 84% identical components. The UH-1Y and AH-1Z completed their developmental testing in early 2006. During the first quarter of 2006 the UH-1Ys were transferred to the Operational Test Unit at the NAS Patuxent River, where they began operational evaluation (OPEVAL) testing. In February 2008, the UH-1Y and AH-1Z began the second and final portion of OPEVAL testing. On 8 August 2008, the Marine Corps certified the UH-1Y as operationally capable and was deployed for the first time in January 2009 as part of the aviation combat element of the 13th Marine Expeditionary Unit. |

The UH-1Y variant modernizes the UH-1 design. Its most noticeable upgrade over previous variants is a four-bladed, all-composite rotor system designed to withstand ballistics up to 23 mm. A 21-inch (530 mm) insert just forward of the main door has been installed for more capacity.

||||||||||||||||||||||
|
The Bell UH-1Y Venom upgrades pilot avionics to a glass cockpit, adds further safety modifications and provides the UH-1 with a modern FLIR system. The Bell UH-1Y is fitted with Lockheed Martin target sight system (TSS) which incorporates a third-generation FLIR sensor. The TSS provides target sighting in day, night or adverse weather conditions. The system has various view modes and can track with FLIR or by TV. Each crew station has two 8in×8in active matrix liquid crystal colour multifunction displays and a 4.2in×4.2in dual function display and data entry keyboard on the central console. Thales Avionics is to supply the TopOwl Helmet Mounted Sight and Display (HMD). The lightweight sight and display includes advanced visor projection with image intensifiers and forward-looking infrared. The communications suite includes the US Navy standard AN/ARC-210 radio, UHF/VHF communications, COMSEC, an APX-100(V) IFF identification friend or foe, a satellite communications interface with a high power amplifier and tactical data modem. The primary navigation system is the US Navy embedded GPS inertial navigation system with an ARN-153 TACAN system and VHF/UHF direction finder. The cockpit is equipped with a digital map for navigation, threat display and in-flight mission planning. The Bell UH-1Y is also equipped with a suite of self-protection and electronic warfare systems including the Northrop Grumman APR-39B(V)2 radar warning receiver and ATK AAR-47(V)2 missile warner and laser detection system. The helicopter also has a BAE Systems Integrated Defense Solutions (formerly Tracor) ALE-47 countermeasures dispenser.

The Bell UH-1Y Venom can be armed with 70mm rockets. The pilot launches the rockets by a trigger squeeze for single, pairs or salvo firings. The helicopter can be fitted with the seven-tube LAU-68, the 19-tube LAU-61 and, with additional software, the seven-tube M-261 or 19-tube M-260 for remote set fusing. The helicopter supports all Mk 66 rockets with unitary, airburst and training warheads. The machine guns selected for the UH-1Y are the M-240D, GAU-16 and GAU-17A. The 7.62mm GAU-17A aircraft machine gun can be fired by either member of crew when in the forward fixed position. The GAU-17A is air-cooled, multi-barreled and electrically powered with a firing rate up to 3,000 rounds a minute. The 0.50-calibre Browning GAU-16A gun is belt fed, recoil operated and air-cooled. The rate of fire is from 750 to 850 rounds a minute. The 7.62mm M-240D is a belt fed, recoil operated, air-cooled machine gun with a rate of fire of 750 to 950 rounds a minute.
- 2 external stations for 70 mm (2.75 in) Hydra 70 or APKWS II[27] rockets - 2 pintle mounts for 7.62 mm M240D machine guns, .50 BMG GAU-16/A machine guns, or 7.62 mm GAU-17/A Gatling guns |
