The aircraft identified by the ICAO type code GRFN and attributed to Griffon Aero (or Griffon Aerospace) lacks verifiable documentation as a certified manned landplane. Extensive research into civil aviation registries, type databases, and manufacturer records indicates that no such manned aircraft model exists in public records. While the name 'Griffon' is widely recognized in aviation history, it most frequently refers to the Rolls-Royce Griffon, a 37-litre, 60-degree V-12 liquid-cooled piston engine produced in the United Kingdom, which powered various World War II-era aircraft such as the Supermarine Spitfire and Avro Shackleton. This engine is distinct from the entity known as Griffon Aerospace.
Griffon Aerospace is an active U.S.-based aerospace firm headquartered in Madison, Alabama, where it maintains approximately 100,000 square feet of industrial manufacturing space. The company specializes in advanced composite structures and unmanned aircraft systems (UAS) rather than manned landplanes. According to corporate records, the company's early history involved support for the Lionheart kitplane, which was produced for a period of seven years by the Lionheart venture. This experience served as a catalyst for the company's expansion into the unmanned market.
In 2003, Griffon Aerospace secured its first prime contract for the MQM-170A Outlaw, also designated as the 'G1,' which served as a target for the U.S. Army's air defense training program. Over the subsequent decade, the company has delivered more than 5,000 unmanned air vehicles under three separate prime production contracts. Despite this extensive production of UAVs, there is no record of a manned aircraft model named 'Griffon' produced by the firm. Consequently, technical specifications, production numbers, and service histories for a manned GRFN aircraft remain undocumented, as the company's operational focus is centered on the UAS and defense sectors.
