    • Soviet 14.5mm ZPU-4 Antiaircraft Gun CHARACTERISTICS Length: 14.5 feet Width: 5.6 feet Height: 7 feet Weight: 2 tons Crew: 5 ARMAMENT Type: Four 14.5 mm. Machine Guns Rate of Fire: 600 Rounds per minute (practical) 2,400 Rounds per minute (cyclic) Range: 1,400 maximum effective range. 8,000 maximum range. The ZPU-4 is a quadruple anti-aircraft version of the basic Soviet 14.5mm Machine gun. Introduced in 1949, it was later used in Korea and was later considered the most dangerous opposition to U.S. helicopters in Vietnam. It was used by Iraqi forces during Operation Desert Storm. The quad ZPU-4 uses a four-wheel carriage similar to that once used by the obsolete 25mm automatic antiaircraft gun M1940. In many units is has been replaced by the newer and more powerful twin 23mm automatic antiaircraft gun ZU-23. This weapon fires a API (armor piercing incendiary) projectile weighing 64.4 grams having a muzzle velocity of 1000 meters per second which will penetrate 32mm of Armor.

    • Disassembly
      • The Small Arms Shop Team spent approximately 180 man hours on the disassembly of this weapon. Most of the weapon and hardware was rusted through due to years of inactivity and exposure to the elements. Further complicating disassembly there were no technical manuals available for this weapon system.
    • Four 14.5 mm Guns
      • The guns themselves were removed from the weapon body, disassembled, thoroughly cleaned, dipped in acid, preserved, repainted, lubricated and reassembled. This was a daunting task as the guns were severely corroded.
    • Completed Guns
    • The Mission Continues
      • While refurbishment was a daunting task, the primary mission of supporting the troops was paramount and took precedence over all work on the AA gun.
    • PAINTING CARC paint was used on the weapon due to it’s high durability and rust preventative properties
    • Reassembly of Weapon The photo documentation of this weapon throughout the refurbishment was extremely useful during the reassembly process as there are no known technical manuals for the team to use.
