Boom’s one-third-scale prototype supersonic jet finally takes off
The private startup Boom has finally flown its third-scale prototype supersonic jet, dubbed XB-1, on its first short flight, taking off on March 22, 2024 from the flight test facility in Mojave, California.
Following behind was Test Pilot Tristan “Geppetto” Brandenburg in a T-38 chase plane to observe the flight and confirm altitude and speed. With a length of 62.6 feet (19 m) and a wingspan of 21 ft (6 m) , the XB-1 achieved an altitude of 7,120 ft (2,170 m) and speeds up to 238 knots (273 mph, 440 km/h) under the force of its three GE J85-15 engines generating a maximum thrust of 12,300 lbs.
According to Boom, once its aerodynamic characteristics and flight worthiness are confirmed, the XB-1 will increase speed until it is flying on later tests in excess of Mach 1.
This prototype supersonic test plane was first unveiled in 2020, four years ago, but runway taxi tests did not begin until 2023. I suspect the Wuhan panic contributed to the three year delay between unveiling and first tests, though this is speculation.
The goal is to build the first commercial superonic passenger plane since the Concorde. At present Boom has a contract from United for fifteen Boom 12-passenger planes, plus development deals with Boeing, and Japan Airlines.
