Firefly Aerospace Signs Rocket Engine Deal Valued at More Than $1.3 Billion with AST SpaceMobile

What happened

Firefly Aerospace signed a three-year agreement with AST SpaceMobile valued at more than $1.3 billion. Firefly will deliver 36 rocket engines, license the engine technology so AST can manufacture engines, and provide engineering support for AST’s new heavy-lift rocket. Firefly says the deal adds funds to accelerate its launch vehicle production.

Confirmed

Global impact / market context

The contract links Firefly’s engine deliveries and technical support to AST’s rocket program, while bringing Firefly additional funds. If delivery and licensing proceed as described, that money could help Firefly advance its own launch vehicle production and broader technology plans, connecting one customer deal to its growth schedule.

Analyst inference

The announcement describes a three-year supply and support agreement, not a reported delivery record or completed rocket program. Its value depends on Firefly fulfilling engine and support commitments and AST using the licensed technology to manufacture engines for its first three rockets.

Analyst inference

What to watch

1. Watch for Firefly’s delivery schedule for the 27 Miranda and nine Vira engines, since delays could affect AST’s plans for its first three rockets. Analyst inference
2. Look for updates on AST’s use of the engine license and whether it begins manufacturing engines as planned under the agreement. Analyst inference
3. Track whether Firefly says the additional funds are accelerating its launch vehicle production and broader technology roadmap, as the company stated they would. Analyst inference
