The ROV is named for Odysseus , protagonist of the Odyssey , and its maximum rated depth, 6,000 m (20,000 ft), measured as metre sea water .
The concept of a shaft-driven lift-fan dates back to the mid-1950s. [9] The lift fan was demonstrated by the Allison Engine Company in 1995–97. [10] The U.S. Department of Defense (DOD) awarded General Electric and Rolls-Royce a $2.1 billion contract to jointly develop the F136 engine as an alternative to the F135.
The rotorcraft was designed to lift a standard Department of Defense, 8 ft × 8 ft × 20 ft (2.4 m × 2.4 m × 6.1 m) MILVAN container weighing up to 22.4 short tons (20,300 kg). [15] Its widely spaced landing gear would allow it to straddle heavy cargoes such as armored vehicles, and still carry twelve troops in its slender fuselage.

The Harrier, informally referred to as the Harrier jump jet, is a family of jet-powered attack aircraft capable of vertical/short takeoff and landing operations (V/STOL). ). Named after the bird of prey, [1] it was originally developed by British manufacturer Hawker Siddeley in the 1
The two-person double chair, which for many years was the workhorse of the ski industry, can move roughly 1,200 people per hour at rope speeds of up to 2.5 m/s (8.2 ft/s). [2] The four person detachable chairlift ("high-speed quad") can transport 2,400 people per hour with an average rope speed of 5 m/s (16.4 ft/s). [ 3 ]
While the second craft was too badly damaged to recover, the first was determined to be repairable and estimated to weigh 12 tonnes (26,000 lb) with fuel, rotors, and non-essential equipment removed. That weight exceeded the maximum payload of 9.1 tonnes (20,000 lb) at an altitude of 2,600 metres (8,500 ft) of the U.S. military's Sikorsky CH-53E.
