The Spitfire Mark II, later given the name Tigershark,[2] was a utility helicopter built in the United States in the late 1970s and intended for series production.
[8] Spitfire displayed a mockup of the Mark II at the Helicopter Association of America meeting in Anaheim, California in February 1977.
[7] Competing plans by Enstrom and Spitfire to market Polish-built Mil Mi-2 helicopters in the United States might have contributed to the friction.
[10] The situation improved somewhat in the 1980s, and Spitfire president Jack Fetsko reported in May 1983 that relations with Enstrom were at the point where the two companies could "talk programs".
[2] By that time, costs for the Mark II, now dubbed the Tigershark, had increased from $185,000 expected in 1979[1] to $305,000[2] but Spitfire had a firm sale for the first production aircraft.
