Firefly agrees to supply engines for AST's first three rockets

On Nov. 6, 2026 Firefly said it will deliver 27 Miranda engines and nine Vira vacuum engines to AST SpaceMobile, license the engine intellectual property, and provide engineering support for three years, for AST's first three heavy-lift rockets. AST will pay more than $1.3 billion in cash and Class A shares, and the release does not split the two. Firefly retains ownership of the engine IP, and it said Miranda has more than 175 hot-fire tests and more than 4,200 seconds.
