About Frontier Aerospace Corporation

Frontier Aerospace Corporation operates in the space propulsion sector, specializing in the design, development, and manufacturing of liquid rocket engines for in-space applications. The company was founded as Frontier Engineering in 1997 by Jim McKinnon, who drew upon his extensive background in rocket propulsion at Pratt & Whitney Rocketdyne to establish the firm. It was later incorporated under its current name in 2014.

The company's business model is centered on securing government research grants and contracts, alongside internal investment, to advance its propulsion technologies. It serves a client base that includes NASA, the Department of Defense, and various commercial aerospace prime contractors. Revenue is generated through contracts for research and development, as well as for the production and delivery of flight-qualified propulsion systems. Key markets include missile defense, satellite maneuvering, deep space exploration, lunar landers, and space transportation.

Frontier Aerospace provides a range of products, including booster rocket engine components, reaction control thrusters, attitude control propulsion systems, and deep space exploration thrusters. A notable product is the TALOS® thruster, developed under a NASA contract, which is designed for low-temperature operations in space. The company's engines were part of a successful flight in 2024, which also marked the first use of MON-25 cold propellant for an exploration mission. Frontier's capabilities cover the full product lifecycle from conceptual design and analysis using modern CAD and simulation tools to manufacturing and rigorous testing.

Significant milestones for the company include being selected in 2018 by Astrobotic to supply attitude control and axial thrusters for its Peregrine Lunar Lander as part of NASA's Commercial Lunar Payload Services (CLPS) program. In 2020, the company achieved an industry first with a successful hypergolic firing using propellants at -40°F. To fund expansion, Frontier Aerospace raised $5.5M in a 2021 seed round and a $10M Series A in 2023, led by AEI HorizonX, to enhance its engine development and build a modern test facility.
