PteroDynamics Inc.
"Game Changing Autonomous VTOL Systems"
Colorado Springs developer of the Transwing folding-wing VTOL UAS, flown at sea for U.S. Navy ship-to-shore logistics and sold to the Royal Australian Navy.
PteroDynamics Inc. is a U.S. developer of autonomous vertical takeoff and landing (VTOL) uncrewed aircraft built around its patented Transwing configuration. It was founded in 2017 by Dr. Val Petrov, who came up with the Transwing concept in 2016 and is the company's chairman. Matthew Graczyk is CEO. The company was first based in Southern California and now names Colorado Springs, Colorado as its headquarters, with a second office in Los Angeles.
On a Transwing aircraft the wings fold dihedrally. On the ground and in hover they stand upright, so the propellers lift like a multirotor. In flight they unfold into a conventional low-drag fixed-wing layout, using the same propulsion system in every flight mode. PteroDynamics says this gives fixed-wing speed, range and endurance together with VTOL stability and gust tolerance. Because the aircraft is stored fully assembled and launches and recovers without catapults or nets, the company says it needs a third or less of the ground footprint of comparable VTOL aircraft. The design is protected by four granted and 15 pending patents in 11 jurisdictions. The company has flown four generations of airframes, from a 4 ft wingspan first prototype to the 13 ft fourth-generation aircraft, and is building a fifth generation with a 21 ft wingspan.
The P4 (shown as XP-4/X-P4) has a published maximum takeoff weight of 89 lb (41 kg) and a maximum payload of 15 lb (6.8 kg). The larger P5 is being developed for the U.S. Navy. Its stated figures are 330 lb (145 kg) maximum gross takeoff weight, 50 lb (23 kg) payload, at least 400 nautical miles range with that payload and a 70-knot cruise. It uses a hybrid-electric powertrain that can burn JP-5 fuel, satellite communications for beyond-visual-line-of-sight operation, detect-and-avoid, and autonomous multi-aircraft operation. It can be carried in C-130, C-17, CH-53 and CH-47 aircraft.
Defense maritime logistics is the main market. The Naval Air Warfare Center Aircraft Division (NAWCAD) has worked with PteroDynamics since 2019. In August 2021 it awarded an Other Transaction Authority contract under the Blue Water Maritime Logistics UAS (BWUAS) program, which evaluates drones for carrying repair parts and supplies between ships and shore. NAWCAD took delivery of its first XP-4 in September 2022. The Transwing flew from the deck of USNS Burlington and took part in RIMPAC 2024. In February 2025 NAWCAD expanded the BWUAS agreement for the sixth time to fund two P5 prototypes for maritime testing. The U.S. Air Force has awarded SBIR/STTR work and a $1.9 million TACFI contract for the fourth-generation aircraft. PteroDynamics also teamed with Leidos on DARPA's Ancillary program.
In May 2026 PteroDynamics announced a competitively awarded Royal Australian Navy contract for P4 Transwing aircraft, training and technical support, to support distributed maritime logistics. Deliveries were set for 2026, with an option for P5 systems from 2027. The company calls this its first international defense sale. It has distribution relationships covering Australasia, Japan (Cornes Technologies), the UK, the UAE and Saudi Arabia. Outside defense, it pitches the aircraft for offshore resupply, oil and gas, wind farm and rail or power-line inspection missions.
PteroDynamics announced a $7.5 million seed round in February 2023. Kairos Ventures, Lavrock Ventures and CS Venture Opportunities Fund led the round. The company's timeline also lists a later second venture round and additional venture financing, without amounts.
