According to the flight international network, on March 16, the U.S. Army awarded bell and Boeing / Sikorsky teams the competitive demonstration qualification for the next phase of the “future long range assault aircraft” (flraa) project.

Flraa is a project under the framework of the future vertical takeoff and landing vehicle (FVL). It plans to develop a medium-sized tactical general-purpose high-speed rotorcraft to replace the active UH-60 Black Hawk helicopter. In August 2014, the U.S. Army awarded the SB-1 of Boeing / Sikorsky team and the v-280 prototype development and test contract of Bell company. Among them, the v-280 prototype made its first flight at the end of 2017 and the SB-1 made its first flight at the beginning of 2019.

According to the requirements of the U.S. Army, the winning design should be able to carry out multiple tasks such as air attack, maritime interception, medical transportation, humanitarian assistance and tactical supply. The maximum cruise speed should reach 280kt (519km / h), the non refueling combat radius should be 300 nautical miles (556 kilometers), and the one-way non refueling range should be at least 2440 nautical miles (4520 kilometers).

In addition, the U.S. Army also said that before the flight competition, the two teams need to improve the aircraft design and provide the first batch of aircraft for the flraa project by 2030.
