In the early to mid 1950s' the ORAF needed a new aircraft for fighter/interceptor roles and thus the Iris was made. The Iris was a mostly experimental aircraft that makes use of a rocket engine rather than a conventional jet or turbo fan, but with only 231gals of fuel it could only fly for about 8-10mins at max. Although, with its powerful engine and light construction (being 9,636lbs loaded and only 8,087lbs empty) it could take off at about 170kts and reach a max speed of around 630kts or nearly mach 0.95 making it OR's fastest of the time. Some other stats of the Iris is that it has a wingspan of 25.8ft, a length of 31.6ft and it was also equipped with a drag chute. To control the plane there was a single pilot that would sit low and enclosed near the front of the aircraft. Lastly, as the Iris was a fighter it was equipped with dual OG-42 12.7mm machine guns, both with a fire rate of 15rps or a rpm of 900. Sadly due to the Irises unconventional way of power only a limited amount of around 500 were made and added to the fact that it was both costly to make and maintain as well as it being outclassed by most jets of the time whilst being prototyped in 1951 and having mass production starting in 1953 by 1954 it was deemed obsolete and production was stopped.
