      The Zastava M55, also designated 20/3-mm-M55, is a Yugoslavian/Serbian 20mm triple-barreled automatic anti-aircraft gun developed in 1955 and produced by Crvena Zastava (now Zastava Arms company) in Kragujevac, Serbia, for Yugoslav People's Army use and also for the export market. In addition to the basic towed model M55 A2, the variants M55 A3 B1, M55 A4 B1, and the BOV-3 SPAAG were also developed.


      Development


      In 1951, the Federal Secretariat of People's Defense (Serbo-Croatian: Savezni sekretarijat za narodnu odbranu – SSNO) purchased the manufacturing licence of the single-barrel Hispano-Suiza HS.804 20mm L/70 anti-aircraft autocannon mounted on the HSS.630-3 towed gun carriage. The HS.804 made by the Crvena Zastava Company entered production in 1955 as the Zastava 20/1mm M55 and the company's engineers began working in the development of a triple-barrelled version; the first prototype was completed and entered production in 1971.


      Variants




      = Ground model M55 A2

      =

      The standard towed version of the M55 introduced in 1971, is intended for infantry use.


      = M55 A3 B1

      =
      The M55 A3 B1 is an improved version of the M55 A2 introduced in 1978.


      = M55 A4 B1

      =
      The M55 A4 B1 was introduced in 1977–78, and is an M55 gun system mounted on the towed carriage of the Swiss GAI-D01 anti-aircraft gun. A new computer-controlled targeting system – the Galileo ballistic computer – was installed, which automatically monitors the gun after the target has been acquired. In addition, an engine of the same type as the M55 A3 B1 has been placed under the gunner's seat, which was moved from the lateral position found on the previous version in order to improve the weight distribution of the three barrels and prevent them from vibrating. When the cannon is put into position, the towed carriage is removed, and a small splinter-proof shield has been installed in front of the targeting device and the gunner.


      = M55 A4 M1 (BOV-3)

      =

      The M55 A4 M1 was first introduced in 1983, and consists on a modified A4 B1 system upgraded with the Galileo J171 ballistic computer, mounted on a turret installed in the top roof of a BOV armoured personnel carrier.


      Combat history




      = Africa

      =
      The Zastava M55 A2 was employed extensively by the People's Armed Forces of Liberation of Angola (FAPLA) during the Angolan Civil War (1975–2002) and the later stages of the South African Border War (1966–1990), with a number of them being captured by the South African Defence Force during their military operations launched against SWAPO/PLAN guerrilla bases at southern Angola in the 1980s. Some of the captured guns were stripped from the triple mounts and re-mounted on the Casspir APCs employed by the Koevoet on their counter-insurgency operations in Angola and South West Africa whilst others were handed over to the Armed Forces of Liberation of Angola, the armed wing of UNITA.
      The Zastava M55 was also employed by the People's Forces of Liberation of Mozambique (FPLM) during both the Mozambican Civil War (1977–1992) and the later phase of the Rhodesian Bush War, with a few guns falling into the hands of the Rhodesian Security Forces in the course of their covert cross-border raids on Zimbabwe African National Liberation Army (ZANLA) guerrilla training camps in Mozambique during the late 1970s.


      = Middle East

      =
      Lebanon received an unspecified number of Zastava M55 A2 autocannons sometime in the early 1970s from Yugoslavia, which were assigned to the air defense units of the Lebanese Army and the Lebanese Air Force. They were extensively employed during the Lebanese Civil War (1975–1990), with several guns falling into the hands of the various competing Christian and Muslim militias after the collapse of the Lebanese Armed Forces in January 1976. Main operators included the Army of Free Lebanon, Lebanese Arab Army, Al-Tanzim, Kataeb Regulatory Forces, Zgharta Liberation Army, the Tigers Militia, Arab Socialist Union, the Druze People's Liberation Army, the Al-Mourabitoun, and the Palestine Liberation Organization who mounted their Zastava M55 autocannons on technicals and M113 armored personnel carriers.


      = 2020 Nagorno-Karabakh War

      =
      Azerbaijan's Ministry of Defence reported that it destroyed two Armenian Zastava M55s 9–10 October 2020 as part of the 2020 Nagorno-Karabakh war.
