The Aestrup EF-105 Gripen is a series of single-engined air superiority fighters designed by Aestrup Luftfahrtsselskab AB for the Acrean Air Force. First entering service in 1959, the Gripen formed a core component of Acrea's air defence forces until the 1970s. With its double delta wing and Mach 2 capability, it was revolutionary at the time of its introduction and was one of the first true supersonic fighters in service.

Although it began its service life in 1959, constant upgrades to the Gripen's peripheral and core systems, avionics, airframe, and powerplants kept it competitive well into its long service life. Owing to its delta wing, the Gripen earned a reputation as a supremely agile and formidable dogfighter, capable of extreme angles of attack. The later EF-105C variant first produced in the mid-1960s was the first aircraft in Acrean service to be fitted with a turbofan engine, drastically increasing the fuel efficiency of the aircraft. The Gripen was continuously updated with new avionics and weapons systems throughout its service life, and thus remained arguably the most capable air-to-air fighter in Acrea's inventory until the introduction of the EF-137 Valkyr, its replacement, in the early 1970s.
