Flight times from London to New York could be slashed to just 3 hours 15 minutes by 2025, thanks to a $10 million (£7.45 million) investment from Japan Airlines.
Boom Supersonic is developing a 55-seat passenger plane that it says will halve flight times and will be faster, quieter and more affordable to fly than Concorde.
As part of the deal Japan’s number two carrier has the option to purchase up to 20 Boom aircraft and will provide its knowledge and experience as an airline to hone the aircraft design and help refine the passenger experience.
Boom Supersonic has said its jetliner, expected to enter service by the mid 2020s, will fly at speeds of Mach 2.2, 10 per cent faster than Concorde, which popularised supersonic jet travel in the 1970s.
The aircraft is expected to produce a sonic boom that would be at least 30 times quieter than Concorde’s, which was dogged by high operating costs and fuel consumption and low capacity utilisation.
The Denver-based startup estimates that fares for its aircraft would be 75 per cent lower than Concorde’s and comparable to current business class tickets, due to its better fuel efficiency.
