The United States has aimed at updating its helicopter fleet in the foreseeable future. A feature of fundamentally new machines will be a higher speed than their predecessors. This is planned to be achieved by applying a new scheme, in which the aircraft will receive one coaxial rotor and one pushing screw in the tail section.
One of the expected novelties in this direction will be a promising Sikorsky-Boeing SB-1 Defiant helicopter, which should soon rise to the sky. As reported by the edition of ExecutiveBiz, the rotorcraft was registered with the US Federal Aviation Administration under the designation S-100. At the same time in the very Lockheed Martin Corporation, which owns Sikorsky, said that they will continue to use for their development the former designation - SB-1 Defiant.
As part of the project, American aircraft builders want to create a car that would replace the well-deserved helicopters UH-60 Black Hawk and CH-47 Chinook and complement the shock AH-64 Apache. Experts have already tested the software for the SB-1, as well as the engine, transmission, hydraulic and fuel systems.

According to calculations, the mass of the new helicopter is 13.6 tons. He will be able to reach speeds of up to 463 km / h and transport up to 12 paratroopers in full computation. During the design of Defiant, the technologies obtained during the development of the technology demonstrator of the high-speed reconnaissance helicopter S-97 Raider were applied. It will be the first car in the new line of high-speed helicopters of the US Armed Forces. The car is seen primarily as an alternative to obsolete light reconnaissance helicopters, such as Bell OH-58 Kiowa. Presumably, the maximum speed of the S-97 Raider will be 444 km / h. The aircraft will be able to carry up to six people, and in addition, will use various weapons.
