Silicon Valley aviation technology firm Reliable Robotics has secured a significant capital infusion. Reports confirmed on Tuesday that the company completed a new funding round of $160 million, elevating its valuation to nearly $1 billion. This capital will support the acceleration of commercialization and regulatory approval processes for its autonomous flight systems.
Based in Mountain View, California, Reliable Robotics stated that the newly acquired funds will be primarily used to expand its engineering team and continue refining technical and safety documentation submitted to the Federal Aviation Administration (FAA). The objective is to demonstrate that its automated flight system meets the safety and reliability standards required for commercial cargo operations.
CEO and co-founder Robert Rose, who previously worked at SpaceX and Tesla (TSLA), emphasized that the company has a clear understanding of the certification pathway. The current focus is on scaling operations to meet regulatory milestones. Reliable Robotics is collaborating with the FAA to advance certification of its autonomous flight system, which enables highly automated control of aircraft during takeoff, cruise, and landing phases. The system is monitored by remote operators who can intervene if necessary.
To date, the company has conducted multiple test flights. Additionally, its fully uncrewed platform has received approval from the U.S. Department of Defense for military use, leading to a contract with the U.S. Air Force. Demonstration flights are expected to begin this year, with the goal of supporting military logistics missions in the Indo-Pacific region.
Reliable Robotics also disclosed that it has secured over 200 letters of intent from commercial and military clients for technical applications. The latest funding round was led by Nimble Partners, with participation from both new and existing investors, including RTX Ventures, the venture capital arm of RTX Corp. John Burbank, founder of Nimble Partners, will join the company’s board of directors.
With this round, Reliable Robotics has raised approximately $300 million in total funding. Strategically, the company is betting on automated flight systems to enhance aviation safety and address the industry's persistent pilot shortage.
Robert Rose noted that certain technologies developed during the autonomous flight research process hold independent commercial value. For instance, advanced radar systems could improve flight safety and reduce accident rates even before fully autonomous aircraft become widespread. He stressed that while "autonomous flight" remains the ultimate goal, intermediate technologies developed along the way can deliver practical and immediate safety improvements to the aviation industry.
