Two hundred customers — airlines, cargo operators, and military buyers — have signed up to buy an autonomous aircraft system from Reliable Robotics. The FAA has not certified that system to fly. The customers signed anyway.
Reliable Robotics announced a $160 million funding round this week, the company's largest to date, putting total funding near $300 million at a near-$1 billion valuation, according to TAMradar. The company says it is pressing for Federal Aviation Administration certification by 2028 and has logged over 200 commitments from commercial and military customers for its autonomous flight system — a level of pre-order demand that the company points to as evidence the market is ready, Morningstar reported. It may be. But the system does not yet exist in a form the FAA has signed off on, and the 2028 target is the company's own projection, not a regulator-assigned deadline, Aviation International News noted.
That gap — between what customers are buying and what the law currently permits — is where Reliable Robotics has built its business model. The company has been selected for the Department of Transportation's Enhanced Special Class Authorization for Innovative Concepts (eIPP) pilot program, a regulatory pathway that lets it operate commercially before full certification through agreements with the FAA called Operational Technology Application authorizations, or OTAs, Morningstar reported. This is not a workaround bolted onto the edges of a proven product. For the foreseeable future, the OTA agreements are the product.
The funding will go toward scaling production and accelerating the certification process. Since its last funding round, the company has nearly tripled its employee base, according to Morningstar, reflecting the labor intensity of the FAA certification process — a multi-year, document-heavy effort that requires proving every failure mode and recovery procedure to the agency's satisfaction. The company declined to specify how many of the 200 commitments involve binding deposits versus non-binding letters of intent.
Robert Rose, Reliable Robotics' CEO, spent seven years at SpaceX as Director of Flight Software and two years at Tesla as Senior Director of Autopilot, experience the company markets as directly applicable to building an aircraft system that needs to make decisions without a human in the loop, The AI Insider reported. The company's autonomous system flew its first uncrewed Cessna in November 2023, a milestone that demonstrated the technical base but did not by itself produce a certificated aircraft, TAMradar noted.
The United States Air Force has separately contracted with Reliable Robotics for a $17.4 million integration deal to develop autonomous cargo operations for contested Indo-Pacific logistics — a use case where the military's appetite for uncrewed logistics aircraft is being driven by strategic competition with China rather than by what the civilian regulatory framework has approved, Morningstar reported. The USAF and FAA programs like eIPP and the similar TACFI pathway are designed to accelerate adoption for regional cargo and Indo-Pacific logistics, in part by giving the military a way to operate autonomous aircraft outside standard civilian certification routes.
The deeper question is whether 200 commitments represents genuine market validation or a strategic bet by customers locking in positions with the first mover. The autonomous cargo market — aircraft that fly cargo routes without a pilot on board — has been perpetually almost-ready for a decade. The technology has advanced substantially. The regulatory path has not kept pace, and the 2028 certification target remains the company's own projection rather than the FAA's.
What Reliable Robotics has that previous attempts did not is both a working prototype and a regulatory seat at the table through the eIPP program. Whether that combination is enough to deliver on 200 pre-orders before the market loses patience is the question hanging over the funding.
