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 exhibits exceptional firing speed, remarkable accuracy, and impressive velocity. However, its lower calibre and the absence of HE filler in its armour-piercing shells require a strategic and precise approach to fully exploit its potential in inflicting maximum damage to the internal components of your adversaries.

Comparison with analogues

The gun is similar to the Soviet 57 mm guns and can be played similarly, but 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:

• The weapon exhibits an impressive reloading rate, allowing for more efficient engagements and quicker follow-up shots.
• The rounds fired from the weapon travel at a commendable speed, enhancing accuracy and reducing the time it takes for projectiles to reach the target, resulting in a lower requirement to account for the lead of the target
• The weapon's handling characteristics are noteworthy, offering ease of manoeuvrability and control during engagements.

Cons:

• Unfortunately, the weapon lacks armor-piercing (AP) shells that incorporate explosive filler. This limits its effectiveness against heavily armored targets, requiring precise shots to inflict significant damage.
• The weapon's calibre is relatively low, which restricts its penetration capabilities and may reduce the overall damage potential against certain opponents.

History

The 6-pounder Ordnance QF Mark V was a tank-mounted variant of the British anti-tank gun. Budget cuts in the British Army during the Great Depression required a level of standardization where British tanks had to use the same weapons as the Royal Artillery anti-tank regiments. The 6pdr OQF Mk.III was an earlier application of this rule with the 6-pounder Mark II simply being mounted in a tank such as the Crusader III. However, after the development of the 6-pounder Mark IV with a single baffle muzzle brake and a longer L/50 barrel, the new gun was fitted into tanks such as the Churchill III and even some armoured cars such as the AEC Mk II as the Mark V. To provide anti-tank support for infantry during beach assaults, the Fairmille H mounted the turret from tanks such as the Churchill III, creating the Fairmile H LCS(L)(2) which used the 6-pounder Mark V also. The 6-pounder was eventually phased out for the OQF Mk.V which was re-chambered to use American 75 mm ammunition, and later the more powerful QF 17-pounder during the later stages of the war.
