Ilyushin Il-30

The Il-28 was upgraded in the Il-30 of 1951 with the Lyulka AL-5 turbojet and 35 degree swept wings to produce a speed of more than 621 mph (1000 km/h), but this had not been ordered into production. The Ilyushin design bureau then moved to a scaled-up version of the Il-28 as the Il-46.
