Operational Context

Mitsubishi SpaceJet — regional twin-engine jet program

The SpaceJet first flew in 2015 under the original MRJ designation. It featured a modern narrow fuselage and geared turbofan engines. Development challenges and certification delays affected the program’s timeline.

Powered by two Pratt & Whitney PW1200G geared turbofan engines producing approximately 15,600 pounds of thrust (69 kN) each, the aircraft was projected to cruise at around 460 knots (852 km/h). Maximum takeoff weight was expected to exceed 85,000 pounds (38,556 kg). Seating would have ranged from 70 to 90 passengers depending on variant.

In 2023, the program was formally terminated after years of delays. Although it did not enter commercial service, the SpaceJet represented a significant attempt to reestablish Japan in the regional jet market.
