Bell UH-1Y Venom
The Bell UH-1Y Venom (also called Super Huey) is a twin-engine, 4-blade, medium-sized utility helicopter built by Bell Textron 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. 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. 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.
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. 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.
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. Bell delivered two UH-1Ys to the U.S. Marine Corps in February 2008, and full-rate production was begun in September 2009. The Marine Corps purchased 160 Y-models to replace their inventory of N-models. The final UH-1Y for the U.S. Marine Corps was delivered in January 2019. In 2021, the production line restarted to produce the UH-1Ys for the Czech Republic's order. 160 have been produced with 8 more being made for the aforementioned Czech order as of 2022.
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.
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, GAU-21, and GAU-17A.
