6pdr OQF Mk.V (57 mm)

Description

The 57 mm 6pdr OQF Mk.V is the tank-mounted version of the 6pdr OQF Mk.IV anti-tank gun, and as with the Mk.IV it features the longer L/50 barrel length. For this reason it has slightly better velocity and penetration to its close sibling the 6pdr OQF Mk.III. The gun features excellent reload speed and good ballistic properties, but as with most British guns will lack HE filler in their AP ammunition.

Vehicles equipped with this weapon

• AEC Mk II
• Churchill III
• Fairmile H LCS(L)(2)
• ▀Pz.Kpfw. Churchill

General info

The 6pdr fires quickly, accurately, and with good velocity, but due to low calibre and lack of HE filler in armour-piercing shells, you will have to shoot intelligently and precisely to maximise damage to your opponent's internal components.

Comparison with analogues

The gun is similar to the Soviet 57 mm guns and can be played similarly, but it should be noted that the Soviet 57 mm uses ammunition with greater amounts of propellant and as such has better penetration and velocity in general, your advantage over this is a slightly faster reload.

Usage in battles

The gun is low calibre and low damage but features good handling, reload speed and penetration for the battle rating it is found at.

Pros and cons

Pros:

• Good reload speed
• Good velocity
• Good gun handling

Cons:

• No AP shells with explosive filler
• Low calibre

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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 />.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
