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
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 speedCeiling
