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.

- Only 50 rounds in a magazine
History
A licensed-built version of the British 2pdr QF Mk.II "pom-poms", the 40 mm/62 Vickers was officially designated the "BI" Type 91 indicating that the licensed version began production in the year 2591 under the Imperial calendar (1931 under the Gregorian calendar). Importation of British "pom-poms" began in 1925 with 500 guns and 200 mountings being imported. Initially fed by 50 round belts, there was an unsuccessful attempt to increase the capacity to 100 round belts. They would be the standard Imperial Japanese Navy anti-aircraft gun until 1935 when the low muzzle velocity and short effective range led to a replacement being sought. Their search led them to the French Hotchkiss 25 mm AA gun which they adopted as the 25 mm/60 Type 96. That said, just about every Japanese ship made between 1925 and 1935 was armed with the Vickers "BI" Type 91.
