20mm Zastava M-55 A2

     Notes:  This weapon is one of three similar antiaircraft guns.  The guns used are license-produced HS-804 guns, three on one mount.  The guns are placed close together to allow quicker reloading.  It is otherwise a very simple weapon.

20mm Zastava M-55 A3 B1

     Notes:  This is an improved version of the M-55 A2.  The main difference is the small gasoline engine to the right of the gunner’s seat to provide power and relieve the gunner of having to manually control the traverse and elevation.  This engine provides 5.22 kW.

20mm Zastava M-55 A4 B1

     Notes:  This is an M-55 gun system on the mount of the Swiss GAI-D01 antiaircraft gun.  In addition, an engine of the same type as the M-55 A3 B1 has been placed under the gunner seat, and a ballistic computer has been added.

20mm M-75

     Notes:  This is basically a single-weapon mount of the same M-1955 autocannon as on the M-55 series of antiaircraft guns.  It can be broken into smaller loads, the largest of which is 55 kilograms in weight.  It is a very simple, basic weapon.

20mm Zastava M-1955

     Notes:  This autocannon is suspiciously similar to the Hispano-Suiza (later Oerlikon) HS-804.  The primary use is on the M-55 3-gun antiaircraft mount, but it has also been seen on a single-gun wheeled mount.

30mm Zastava M-86

     Notes:  This Yugoslavian design is intended for mounting on armored vehicles or antiaircraft mounts.  The M-68 can feed from either side, but is not a dual-feed weapon; only one belt may be loaded in the weapon at a time.  It is designed for low-recoil operation, but its belt-pulling power is not great, limiting the potential belt length.  Firing is electrical.
