Firefly’s $1.3 Billion Engine Deal Gives AST SpaceMobile a Path Toward Its Own Rockets

November 7, 2026 — Satellite broadband operator AST SpaceMobile is moving toward building its own launch vehicle, signing an engine-supply and technology agreement with Firefly Aerospace worth more than $1.3 billion. The announcement, made November 6, illustrates a strategic shift: a satellite company seeking greater control over the rockets that carry its network into orbit.

What the agreement actually covers

According to Firefly’s November 6 announcement, the three-year arrangement includes 36 engines for AST’s planned Blacklift rocket: 27 Miranda engines and nine vacuum-optimized Vira engines, intended for the first three vehicles. Firefly will also provide engineering support and license engine intellectual property, allowing AST eventually to manufacture engines itself. The consideration comprises cash and AST Class A shares, subject to lock-up provisions.

These are contractual plans, not evidence that Blacklift has already flown. Firefly says the Miranda engine has completed more than 175 hot-fire tests, but a tested engine is not the same as a flight-proven new rocket.

Why a mobile-satellite company wants rockets

AST is developing a direct-to-device satellite network designed to connect ordinary mobile phones. Its Blacklift project description says the rocket is intended to carry up to five BlueBird satellites per launch. Owning a dedicated launch system could eventually give AST more influence over deployment timing, instead of relying entirely on available third-party launch slots.

That ambition brings a trade-off. Designing, qualifying and repeatedly operating a launch vehicle demands substantial capital, specialist talent and years of engineering execution. An engine supply agreement can address one major bottleneck, but it does not eliminate risks involving structures, guidance, launch facilities, regulatory approvals or schedule delays.

What investors and customers should watch

The key milestones are engine deliveries, integrated vehicle tests, a demonstrated launch capability and ultimately reliable repeat flights. The size of the deal should not be confused with revenue already recognized, nor should AST’s stated ambitions be treated as guaranteed deployment capacity. Reuters reported the agreement on November 6, noting AST’s effort to reduce reliance on outside launch providers.

Bottom line: Blacklift could make launch access part of AST’s competitive strategy, but the commercial advantage will depend on whether an announced rocket program becomes an operational, economical transportation service.
