The Bofors L/70 Mk.1 (57 mm) is a naval autocannon designed to engage both air and surface targets. It was developed form the earlier Bofors 57 mm L/60, a twin-barrel naval autocannon, basically a scaled-up version of the [[Bofors L/60 Mark 1 (40 mm)]].

The Bofors L/70 Mk.1 (57 mm) on the Begleitpanzer 57 gun mantlet.

Description

The 57 mm Bofors L/70 Mk.1 is a naval autocannon designed to engage both air and surface targets. It was developed form the earlier Bofors 57 mm L/60, a twin-barrel naval autocannon, basically a scaled-up version of the 40 mm Bofors L/60 Mark 1.

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

The 57 mm Bofors L/70 cannon will face MBTs and heavy tanks, but it can still make work of its capabilities. When dealing with other ground units, the key here is to be on the flank of the enemy as most side armour of MBTs, NATO and Soviet can be pierced with the 57 mm AP rounds. As the 57 mm does not have an explosive filler with its AP shell, and SAPHEI being near useless, the cannon requires to aim at key components such as ammo rack or general area where the crew sits. With your high rate of fire rate, you can disable most targets and not worry where to aim for the most part with the APCBC shell. Although the 57 mm has access to SAPHEI and can overpressure enemies, it's mainly only effective against lightly-armoured vehicles.

Against aircraft, HE-VT is very effective, having a good velocity and damage to disable targets. Helicopters will stand no chance against the 57 mm once they are spotted, and a few volleys of HE-VT will heavily damage them at least to hinder their combat capabilities. Against jets and other aircraft, the 57 mm has just enough rate of fire to disable jet aircraft, though you will have to lead more the faster they are.

Pros and cons

Pros:

  • Good rate of fire for its calibre
  • Good anti-tank capabilities with the APCBC
  • Access to HE-VT shells

Cons:

  • SAPHEI is near useless except on light vehicles
  • No APFSDS unlike its 40 mm variant

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.
