The Bell UH-1Y Venom[3] (also called Super Huey)[4] is a twin-engine, 4-blade, medium-sized utility helicopter built by Bell Helicopter under the H-1 upgrade program of the United States Marine Corps. One of the latest members of the numerous Huey family, the UH-1Y is also called "Yankee" for the NATO phonetic alphabet pronunciation of its variant letter.[5] Bell was originally to produce UH-1Ys by rebuilding UH-1Ns, but ultimately used new built airframes.
In 2008, the UH-1Y entered service with the Marine Corps and also began full-rate production.[6] The new UH-1 variant replaced the USMC's UH-1N Twin Huey light utility helicopters, introduced in the early 1970s. The helicopter (and related Bell AH-1Z Viper) were ordered by the Czech Republic and the helicopter is in production in the early 2020s. Visually, some features that differentiate the Y model are a slightly longer cabin and larger twin engine exhaust vents compared to the earlier N model.
Development
[edit]![](http://upload.wikimedia.org/wikipedia/commons/thumb/9/99/UH-1Y.jpg/220px-UH-1Y.jpg)
Over the years, new avionics and radios, modern door guns, and safety upgrades have greatly increased the UH-1N's empty weight. With a maximum speed around 100 knots (190 km/h) and an inability to lift much more than its own crew, fuel, and ammunition, the UH-1N had limited capabilities as a transport.[citation needed]
In 1996, the United States Marine Corps launched the H-1 upgrade program. A contract was signed with Bell Helicopter for upgrading 100 UH-1Ns into UH-1Ys and upgrading 180 AH-1Ws into AH-1Zs.[7][8] The H-1 program modernized utility and attack helicopters with considerable design commonality to reduce operating costs. The UH-1Y and AH-1Z share a common tail boom, engines, rotor system, drivetrain, avionics architecture, software, controls, and displays for over 84% identical components.[9][10]
Production
[edit]Originally, the UH-1Y was to be remanufactured from UH-1N airframes, but in April 2005, approval was granted to build them as new helicopters.[6][11] Bell delivered two UH-1Ys to the U.S. Marine Corps in February 2008,[12] and full-rate production was begun in September 2009.[13] The Marine Corps purchased 160 Y-models to replace their inventory of N-models.[14] The final UH-1Y for the U.S. Marine Corps[15] was delivered in January 2019.[16] In 2021, the production line restarted to produce the UH-1Ys for the Czech Republic's order.[17] 160 have been produced with 8 more being made for the aforementioned Czech order as of 2022.[2]

The UH-1Y variant modernizes the UH-1 design. The Y-model upgrades pilot avionics to a glass cockpit, adds further safety modifications, and provides the UH-1 with a modern forward-looking infrared system. Engine power was increased. Its most noticeable upgrade over previous variants is a four-blade, all-composite rotor system designed to withstand up to 23 mm rounds. By replacing the engines and the two-bladed rotor system with four composite blades, the Y-model returns the Huey to the utility role for which it was designed.
A 21-inch (530 mm) fuselage extension just forward of the main door was added for more capacity. The UH-1Y features upgraded transmissions and a digital cockpit with flat-panel multifunctional displays. Compared to the UH-1N, the Y-model has an increased payload, almost 50% greater range, a reduction in vibration, and higher cruising speed.[9][18][19]
The weapons used on the UH-1Y includes a variety of rocket and machine guns. This includes 2.75-inch (70 mm) rockets on the external hardpoints, and LAU-68, LAU-61, M260, and M261 launchers with Mk 66 rockets (Hydra 70). Machine guns include M240D, GAU-16 and GAU-17A.[20]

The UH-1Y and AH-1Z completed their developmental testing in early 2006.[21] During the first quarter of 2006 the UH-1Ys were transferred to the Operational Test Unit at NAS Patuxent River, where they began operational evaluation testing.[22] In February 2008, the UH-1Y and AH-1Z began the second and final portion of testing.[23] On 8 August 2008, the Marine Corps certified the UH-1Y as operationally capable, and it was deployed for the first time in January 2009 as part of the aviation combat element of the 13th Marine Expeditionary Unit.[24][25] The UH-1N Twin Huey was retired by the Marines in August 2014, making the UH-1Y the Marine Corps' standard utility helicopter.[26]
On 11 October 2017, the Defense Security Cooperation Agency notified the United States Congress of the potential sale of 12 UH-1Ys and related systems and support to the Czech Republic for a cost of US$575 million.[27] In December 2019, an order for eight UH-1Y helicopters was approved.[28][29] The first Czech UH-Y was delivered in 2023.[30]
