AST SpaceMobile Commits $1.3 Billion to Blacklift Rocket and Engine Development

AST SpaceMobile has entered into agreements with Firefly Aerospace totaling approximately $1.3 billion to develop its reusable Blacklift rocket and establish in-house manufacturing of Firefly’s Miranda and Vira engines. The package combines an approximately $800 million perpetual license for AST to manufacture the engines, $250 million for engines for the first three Blacklift rockets, and $250 million for engineering services. AST plans to begin launches in late 2028, making the arrangements a substantial commercial investment in launch-vehicle development and propulsion capability.

For government contractors, the announcement is relevant as an indicator of potential future launch capacity and supply-chain demand, rather than as a near-term federal procurement opportunity. AST says the capability will support government customers and missions under its DPAS-rated program; the signal also links that support to Golden Dome. Those statements describe the company’s intended mission support, but the agreements disclosed are commercial arrangements between AST and Firefly. They do not establish a funded government requirement, an open competition, or a government award to either company.

The agreement structure also points to distinct areas of potential industry engagement. The perpetual license is intended to enable AST to manufacture Miranda and Vira engines in-house, while the first three rockets’ engines are covered by a separate $250 million commitment. A further $250 million covers engineering services over a three-year period. This combination could create downstream needs in manufacturing equipment, components, quality assurance, testing, production support, and launch operations as the program moves from development toward planned launches. Companies considering entry should validate requirements with AST or Firefly rather than treating the reported investment as evidence of a federal solicitation.

The decision to partner with Firefly on propulsion is strategically important because engine development is a high-risk, schedule-critical part of building a new rocket. Firefly CEO Jason Kim said, “When a company sets out to build its own rocket, the engine is the hardest, highest-stakes decision they make, and AST SpaceMobile has chosen to partner with Firefly for its most powerful rocket engines.” For GovCon firms, the key watchpoints are execution against the engineering and manufacturing plans, progress toward the late-2028 launch target, and any separately announced government requirements or awards. The current signal is best classified as company-focused commercial development with possible future relevance to government missions—not as a present bidding lead.

• Total announced value: AST SpaceMobile’s agreements with Firefly Aerospace are approximately $1.3 billion.
• Engine manufacturing license: Approximately $800 million for a perpetual license allowing AST to manufacture Firefly’s Miranda and Vira engines.
• Initial engine commitment: $250 million for engines for the first three Blacklift rockets.
• Engineering services: $250 million for a three-year period of engineering services.
• Launch schedule: AST plans to begin Blacklift launches in late 2028.
• Government relevance: AST says the capability will support government customers and missions under its DPAS-rated program; the signal also associates that support with Golden Dome.
• Opportunity status: The disclosed arrangements are commercial supplier agreements, not an open government solicitation or a disclosed government contract award.
• Potential supplier areas: Firms may monitor AST and Firefly for emerging needs in propulsion manufacturing, components, testing, quality assurance, engineering, and production support.
• Contractor action: Distinguish AST’s commercial investment and stated government-mission plans from a funded government requirement; confirm any future opportunities through formal agency notices or company announcements.
• Execution watchpoints: Track engineering progress, engine-manufacturing readiness, and movement toward the late-2028 launch target before making assumptions about delivery schedules or government demand.
