In 1940 three I.A.R.47 prototypes were under construction, intended to replace the I.A.R.39 in production. Of the IAR-47 manufactured - the first for static tests, while the other two were actually flown. These two were of different design. The other prototype was a combination of the IAR-39's fuselage with the IAR-80's wings. According to the memoirs of one of the IAR plant's chief engineers, the IAR-47's crew consisted of three airmen, the powerplant was an IAR K14 1000A and the top speed reached was 304mph (490kph). None of them were destroyed during US bombings, and at least one was still flying in 1948.
