Game Aerospace GB2 Stormbird Completes First Flight

Game Aerospace successfully completed the first flight of its GB2 Stormbird prototype on September 23, 2026, advancing the development of the first purpose-built aerial firefighting aircraft designed in the United States.

Flown from Louise Thaden Field (KVBT) in Bentonville, Arkansas, the all-composite aircraft completed all planned initial evaluations. In a press release issued by the company, Game Aerospace confirmed the milestone moves the program into its formal flight-test phase aimed at Federal Aviation Administration (FAA) Part 23 standard-category certification.

Design and payload specifications

The GB2, designed specifically for initial attack firefighting missions, features a two-seat cockpit to support both operational flexibility and training. The prototype recorded an empty weight of 6,050 pounds against a maximum gross weight of 19,000 pounds.

This weight profile allows for a mission payload capacity of 1,200 gallons of water or fire retardant, alongside a 400-gallon fuel capacity. According to background specifications reported by AOPA, the aircraft is estimated to achieve a cruise speed of 200 knots.

Market positioning and development history

The aerial firefighting sector has historically relied on Single Engine Air Tankers (SEATs), which are typically modified agricultural aircraft such as the Air Tractor AT-802. Aerospace Global News notes that standard SEATs generally carry up to 800 gallons of payload. The 1,200-gallon capacity of the GB2 places it in the larger Type 3 airtanker classification.

Game Aerospace CEO, co-founder, and test pilot Philipp Steinbach piloted the first flight.

“The GB2’s successful first flight is the result of years of engineering, craftsmanship, and dedication from our entire team, as well as great collaboration with the FAA,” Steinbach said in the company statement. “Our goal is to provide the world’s most cost-effective aerial firefighting solution, an aircraft designed from the outset around the mission.”

The company, formerly known as Game Composites, accelerated the GB2 program following its January 15, 2025, acquisition of Grove Aircraft Landing Gear Systems. This acquisition prompted the corporate rebranding to Game Aerospace, as reported by Aviation Week.

AirPro News analysis

We view the GB2 Stormbird as a potential disruptor in the initial attack firefighting market. By designing a clean-sheet, all-composite airframe specifically for fire retardant drops rather than retrofitting agricultural sprayers, Game Aerospace can optimize the payload fraction and drop characteristics. The transition from a 6,050-pound empty weight to a 19,000-pound maximum gross weight demonstrates a highly efficient structural design. If the company successfully navigates FAA Part 23 certification, the GB2 could offer state and federal forestry agencies a higher-capacity alternative to legacy SEAT platforms without requiring the infrastructure of large multi-engine airtankers.
