Source measurement	Compared to the Galeb, the Jastreb has a strengthened structure, allowing more weapons to be carried, including three 12.7 mm (0.5 in) Browning AN/M3 machine guns, mounted in the nose of the aircraft. Also, the Jastreb is able to carry up to 800 kg (1,800 lb) on under-wing pylons, two inner pylons having a capacity of 250 kg (550 lb) for bombs, rocket launchers, and additional tanks, while the six outer pylons can carry VRZ-157 127 mm (5.00 in) rockets.^[source]Soko J-21 Jastreb · Design and development; only the objects and conditions stated in this passage The first Yugoslav Air Force attack on Croatian troops took place on July 9, 1991 near Ilok, when two J-21 Jastreb attacked the base of the 1st Brigade of the Croatian National Guard .
