DARPA Awards Redwire $20 Million for Subscale VLEO Demonstration

The Defense Advanced Research Projects Agency (DARPA) awarded Redwire a $20 million contract under its Otter program to conduct a precursor mission for very-low-Earth-orbit (VLEO) spacecraft. The mission will use a scaled-down version of Redwire’s SabreSat spacecraft and air-breathing electric propulsion (ABEP). DARPA’s longer-term objective for Otter is to develop propulsion technology that could support satellites operating between 90 and 250 kilometers above Earth. The subscale flight is targeted for late 2027 and is expected to operate in VLEO for less than a day, testing technology under flight conditions before a full-scale demonstration. DARPA has not announced a date for that later mission.

VLEO offers potential operational advantages from flying closer to Earth, but it also presents engineering challenges. Atmospheric drag can shorten spacecraft lifetimes, making propulsion, vehicle design, and mission operations important parts of the technology problem. Redwire says ABEP is intended to address the low-altitude environment and support maneuverable, energy-efficient spacecraft. Redwire Senior Vice President of Missions and Platforms Spence Wise described the goal as a new class of spacecraft able to support “persistent operations in critical orbital regimes,” with potential advantages in “rapid orbital agility” and “enhanced tactical responsiveness.” These are stated objectives, not demonstrated mission outcomes; the precursor flight is intended to gather data and reduce uncertainty before the full-scale effort.

For GovCon companies, the award is an indicator of continued federal investment in VLEO and propulsion research, rather than a currently available bid. Potential areas of relevance include spacecraft and propulsion components, systems integration, digital engineering, modeling, testing, and mission support. Redwire said the subscale flight will provide data that cannot be fully recreated on the ground and help the program “learn faster” before the full Otter mission. The signal does not identify a new solicitation, a named subcontracting requirement, or a timetable for follow-on procurement, so companies should treat it as a technology and market-development signal rather than a near-term capture notice.

The $20 million award follows a separate $44 million Redwire award under Otter in November 2025, described in the source as a Phase 2 award. Redwire is also prime contractor for the European Space Agency’s (ESA) Skimsat effort, which aims to develop VLEO capability for Europe and is targeting a first flight no earlier than 2027. The two programs are being developed in parallel, but Redwire notes that not all subsystems are transferable because of regulatory constraints. Wise said the company is pursuing efficiencies “where permitted,” including potential use of enterprise digital-engineering tools across both efforts, subject to applicable laws and export-control requirements. Companies considering cross-border participation should account for those restrictions. The source also reports Redwire’s third-quarter 2026 results: quarterly revenue increased 5.4% year over year, gross margin reached a record 32.3%, and net loss decreased by $18 million; it does not provide the resulting net-loss figure in the supplied text.

• DARPA’s $20 million Otter award funds a subscale Redwire VLEO precursor mission using air-breathing electric propulsion.
• The flight is targeted for late 2027 and is expected to spend less than one day in VLEO.
• Otter’s stated long-term operating range is 90–250 kilometers above Earth.
• The precursor mission is intended to test technology in orbit, gather data unavailable from ground testing alone, and reduce risk before a full-scale demonstration.
• DARPA has not announced a date for the full-scale Otter mission; the source identifies no open solicitation or specific subcontract opportunity.
• Redwire previously received a separate $44 million Otter-program award in November 2025.
• Redwire is prime contractor for ESA’s Skimsat effort, which targets a first flight no earlier than 2027.
• Cross-program efficiencies may include digital engineering, but collaboration is constrained by applicable laws and export-control requirements.
• Redwire’s reported Q3 2026 highlights include 5.4% year-over-year revenue growth, record 32.3% gross margins, and an $18 million decrease in net loss; the supplied source does not state the resulting loss figure.
