Firefly Aerospace & AST SpaceMobile signed a three-year agreement valued at over $1.3 billion to support AST's new heavy-lift rocket program.
The deal includes delivery of 36 rocket engines: 27 Miranda engines & 9 Vira vacuum-variant engines for AST's first three rockets.
Firefly will provide a license for AST SpaceMobile to manufacture the engines itself while retaining full ownership of the intellectual property.
Firefly will receive funding in the form of cash & AST Class A Common Stock subject to lock-up periods to accelerate its own launch vehicle production.
AST SpaceMobile gains control over its launch schedule by securing access to powerful liquid engines from Firefly.
Firefly plans to use the funds to expand hiring, procure long-lead materials, source equipment, & build new test bays at its Rocket Ranch in Briggs, Texas.
Firefly's Miranda engine has completed over 175 hot fire tests totaling more than 4,200 seconds, including a flight-like test at 110% performance.
Both companies are headquartered in Texas & have non-competitive business portfolios with complementary missions.
Firefly will discuss the agreement during its Third Quarter 2026 Earnings call scheduled for November 10, 2026.
