A co-development programme between the Ministry of Defence and UK start-up Alloyed reported on 15 September 2026 that one turbojet engine went from initial concept to flight-ready status in less than seven months. The programme has produced a family of digitally manufactured turbojet engines, designed, built and tested in Britain, spanning a 30N to 2000N thrust range and intended for uses from small drones to larger aircraft, according to the announcement.

Two engines have entered production: a 300N-class engine that completed flight testing and is now in serial production in the UK, and the 1100N-class engine that progressed from concept to flight-ready in under seven months. The programme, led by the MOD's Strategic Capabilities Office with matched funding from Alloyed, involves more than 40 UK suppliers, mainly small and medium-sized enterprises.

More than 60 engineering and advanced manufacturing jobs have been created, with a further 45 anticipated over the next 12 months as production expands. Defence Readiness and Industry Minister Luke Pollard said the programme shows defence and industry working together at pace. Alloyed chief executive Michael Holmes credited the MOD partnership with demonstrating advanced propulsion systems quickly while building UK capability.
