The Bell UH-1Y Venom is an American medium size utility helicopter.

The Venom is currently in low-rate production to replace the United States Marine Corps aging fleet of UH-1N Twin Huey light utility helicopters first introduced in the early 1970s. Originally the UH-1Y was to have been remanufactured from UH-1N airframes, but in April 2005 the aircraft were approved to be built as new helicopters. [ [http://www.news.navy.mil/search/displaybbs.asp?bbs_id=1332&cat=5 UH-1Ys to be built new starting in 06 ] ]


In 1996, the USMC launched the H-1 upgrade program by signing a contract with Bell Helicopter for upgrading 100 UH-1Ns into UH-1Ys and upgrading 180 AH-1Ws into AH-1Zs.Donald, David. "Modern Battlefield Warplanes". AIRTime Publishing, 2004. ISBN 1-880588-76-5.] Bishop, Chris. "Huey Cobra Gunships". Osprey Publishing, 2006. ISBN 1-84176-984-3.] The H-1 program created completely modernized attack and utility helicopters with considerable design commonality to reduce operating costs. The UH-1Y and AH-1Z share a common tail boom, engines, rotor system, drive train, avionics architecture, software, controls and displays for over 84% identical components. [http://www.bellhelicopter.com/en/aircraft/military/pdf/UH1Y_PG_3-06_web.pdf Bell UH-1Y pocket guide] , Bell Helicopter, Retrieved 16 August 2008.] [http://www.bellhelicopter.com/en/support/pdf/rb/rb_oct18.pdf "Rotorbreeze Magazine"] , Bell, October 2006.]

The Y model updates an airframe that has been central to the Marine Corps aviation in Iraq. The Huey has many mission requirements including command and control (C2), escort, reconnaissance, troop transport, medical evacuation and close air support. Typically detachments of 2-4 Hueys have been deployed with detachments of 4-8 Cobras. The forward mounted weaponry of the Cobra combined with the door guns of the Huey provides a 240° field of fire.

Over the years new avionics and radios, in addition to modern door guns and safety upgrades, have greatly increased the UH-1N's empty weight. With a maximum speed of approximately 100 knots and an inability to lift much more than its own crew, fuel and ammunition, the UH-1N, while useful, is limited in its utility.

The Y model upgrades pilot avionics to a glass cockpit, adds further safety modifications and provides the Huey with a modern FLIR system. However, the biggest improvement is an increase in engine power. By replacing the engines and the two bladed rotor system with four composite blades the Y model will return the Huey to the utility role it was designed for.

According to Bell the Y model will have 125% higher payload than the UH-1N, and almost 50% greater range and maximum cruise speed than the UH-1N. [ [http://www.bellhelicopter.com/en/aircraft/military/bellUH-1Y.cfm UH-1Y page] , Bell.] The Venom can keep up with the other helicopters it is supposed to be escorting rather than slowing them down and making them easier targets. The UH-1Y will have the power needed to maneuver aggressively and evasively. Ground forces commanders riding in the Venom will have all the radios and fire power they need and the range of the transport helicopters carrying their men.

On November 18, 2006, the first production model UH-1Y completed its first flightFact|date=March 2007 and is currently being tested by the US Marine Corps. UH-1Y deliveries began in February 2008. A full-rate production decision is expected later in 2008. [http://www.bellhelicopter.com/en/company/pressReleases/PR_08_0305_threeH-1Delivered.cfm "Bell H-1 upgrade program delivers two UH-1Y and one AH-1Z in February"] , Bell Helicopter, March 3, 2008.]


The UH-1Y variant modernizes the UH-1 design. Its most noticeable upgrade, as compared to previous variants, is a four-bladed, all-composite rotor system designed to withstand ballistics up to 23 mm. A 21 inch insert just forward of the main door has been installed for more capacity. The UH-1Y has upgraded engines and transmission, 170% increased payload over UH-1N, almost 50% greater range and maximum speed, a digital cockpit with flat panel multifunctional displays, and an 84 percent parts commonality with the AH-1Z.

Operational history

Bell delivered a UH-1Y to the U.S. Marine Corps on February 26, 2008, for February's third H-1 Upgrade delivery. The previous February deliveries were an AH-1Z on February 8, and an UH-1Y on February 13. The H-1 program began Phase II of its Operational Evaluation on Feb. 13.

On August 8, 2008, the Marine Corps certified the UH-1Y as operationally capable and will deploy it for the first time in January 2009 as part of the aviation combat element of the 13th Marine Expeditionary Unit. The Marine Corps plans to eventually buy 123 of the Y-model Hueys to replace their inventory of N-models [cite web
