IAR 471

The IAR 471 was a Romanian World War II prototype of ground attack aircraft and dive bomber aircraft built in 1943 by Industria Aeronautică Română (IAR).

The IAR-81 had not proved a great success as an improvised dive bomber and experience with the IAR-47 showed that the IAR K14 would not be up to the demands of powering a full-sized dive bomber. Thus by early 1943 the Royal Romanian Air Force still lacked an effective ground support aircraft. In November 1942, IAR had at last secured a license for the manufacture of the German DB 605 engine and planning now centred on this powerplant. On January 16, 1943, a new dive bomber project, the IAR-471, was commissioned which was to be powered by the DB 605. Although the Germans lent Romania numerous Stukas from mid-1943, they would not sell any. Therefore, the design of the IAR-471 was persevered with for reasons of self-sufficiency.

Despite its designation, the IAR-471 bore little resemblance to the smaller IAR 47 and was essentially a different aircraft. It was designed with a superior performance to the Stuka, much helped by the retractable undercarriage, but a lighter bomb load, and on May 7, 1944, the Stuka's two underwing 37mm cannons were ordered to be included in its specification. It was planned to order 100 IAR-471s and 136 engines from IAR in 1944/1945, but IAR was in the throes of dispersing its factories and beginning production of the Bf 109G and declared itself incapable of simultaneously producing the IAR-471. This halted the project even before Romania's defection to the Allies on August 23, 1944. No prototype flew.^[1] There were (at least) one IAR 471 prototypes built.
