ONE Bow River National Defense Fund has made a strategic investment in PteroDynamics Inc., an innovator in autonomous vertical takeoff and landing (VTOL) aircraft systems. The investment will enable PteroDynamics to accelerate development and flight testing of the company's novel Transwing VTOL unmanned aircraft systems (UAS) and scale manufacturing to meet growing global demand in the defence and commercial sectors.

ONE Bow River's National Defense Fund invests in critical technology companies that aim to advance U.S. national security and strengthen the industrial base. PteroDynamics' Transwing is a revolutionary VTOL aircraft system that folds its wings to transition between configurations optimised for vertical and winged horizontal flight.

"The need for next-generation VTOL UAS platforms to automate surveillance and contested logistics operations to remote locations in harsh environments is growing every day," said Kevin O'Neil, Chief Investment Officer at ONE Bow River. "That is exactly the area where PteroDynamics excels. We're committed to helping PteroDynamics scale its engineering, operations, and manufacturing to take advantage of a growing market opportunity."

"PteroDynamics is at an exciting inflection point. The Transwing's unique performance capabilities and compelling multi-mission flexibility are attracting increasing interest from defence and commercial operators in the U.S. and around the world," said PteroDynamics CEO Matthew Graczyk. "The strategic partnership with ONE Bow River allows us to leverage their deep operational expertise and industry and government relationships to seize these opportunities while delivering more value to the market."

The strategic growth investment will support the buildout of PteroDynamics engineering operations, further development of the Transwing VTOL UAS platform, flight testing, and scaled manufacturing. PteroDynamics Transwing UAS platform aligns with the ONE Bow River's focus on differentiated technology platforms that support contested logistics, aerospace, and national defence readiness.

The autonomous fourth-generation P4 Transwing VTOL UAS has a take-off weight of 89 pounds with a maximum payload of 15 pounds. In 2025, the U.S. Navy awarded PteroDynamics a contract to design and develop the company's larger fifth-generation P5 Transwing, which will have a maximum take-off weight of 330 pounds and a range of over 400 nautical miles carrying a 50-pound payload at 70 knots. Initial flight testing begins later this summer.
