Firefly signs engine and licensing agreement worth more than $1.3 billion with AST SpaceMobile

Firefly agreed to supply 36 rocket engines to AST SpaceMobile for its first three Blacklift heavy-lift rockets. The package includes 27 Miranda main engines and nine Vira vacuum engines, intellectual-property licensing and engineering support over three years. AST will receive a licence to manufacture the engines itself, while Firefly retains ownership of its engine intellectual property.

Why it matters

The agreement is a major commercial commitment for Firefly's propulsion business and could materially expand its engine production base. The licensing component also creates a pathway for AST to internalize manufacturing over time, so the long-term supplier relationship may evolve.
