Comparison with analogues

  • 2pdr QF Mk.IIc (40 mm) - The original Vickers 40 mm AA gun, this one fires shells at a much higher velocity, but lacks any fused shells, and a larger magazine at 56 rounds.
  • 40 mm/39 Vickers-Terni mod.1915/1917 - Only equipped on large ships, this Italian pdr QF Mk.II has 25 rounds per magazine and only has access a single shell type, HE-TF. It also fires at a slightly higher velocity, but only has about half the explosive mass of the 40mm/62 Vickers.
  • 40 mm/39 Vickers-Terni mod.1915/1917, Modif.1930 - A modernized variant of the above, this one has 50 round magazines, but only access to HEF shells, which like the Italian HE-TF, has less explosive mass and higher velocity.
  • Bofors L/60 Mark 1 (40 mm) · Bofors L/60 Mark 2 (40 mm) · Bofors L/60 Mark 3 (40 mm) - The 40 mm Bofors has a much higher muzzle velocity, making it easier to aim and the ability to fire continuously, though it has a lower rate of fire.
  • 37 mm/67 70-K - Soviet AA gun similar to the Bofors, has a higher muzzle velocity and lower rate of fire. Its HEF shells have a slightly lower explosive mass.
  • 3.7 cm FlaK-Lafette C/36 - German AA gun, again similar to the Bofors. Has a higher rate of fire, but a much weaker HEF round.
