The J-451MM lead to development of the Ikarus T-451MM Stršljen II (“Hornet II”) single seat jet aerobatic training aircraft of which only one prototype (21002) was manufactured and this can now be seen at the Belgrade Aeronautical Museum.
Another variant was the Ikarus S-451MM Matica (“Queen Bee”) two-seat jet training aircraft which set a world air speed record for its class of 750.34 km/h in 1957.
