Description
Following the battle experiences in North Africa, there was a need among Churchill tank crews for a better armament in order to support the infantry. Early Churchill tanks were armed with cannons that had relatively lackluster high-explosive capabilities like the 2-pounder and 6-pounder guns. An enterprising REME (Royal Electric and Mechanical Engineers) Captain, Percy Morrell, recognized that there were many M4 Shermans slated to be scrapped with still functioning 75 mm armament. In a bid to upgrade the Churchill tanks for combat, he suggested and proved the feasibility of taking the M34 gun mantlet and 75 mm M3 cannon off the M4 Sherman tanks and installing them onto the turret face of the Churchill tanks. The modified Churchills, mostly Mark IVs, were given top priority with 200 modified with the M4 Sherman mantlet prior to June 1944. The modified tank was designated "NA75" (for North Africa 75 mm) and was sent to the Italian theater to fight, most notably during the assaults against the Gothic Line.
Introduced in Update "Sky Guardians", the Tank, Infantry, Mk IV, Churchill NA75 can be seen as a sidegrade grade of the Churchill III, but with a 75 mm gun and a different turret design. This leads to somewhat lower penetration values compared to what the 6-pounder on the Mk III can provide, but the post-penetration damage on the NA75 is much stronger than what the 6-pounder can deliver. Another minor change to the NA75's benefit is stronger turret front armour due to the usage of the M4 Sherman mantlet in the turret front. However, with the same weight and engine as the Mk III, the Churchill NA75's manoeuverability on the battlefield will be very similar, if not exactly identical.
General info
Survivability and armour
The Churchill NA75 has the ability to angle the tank to improve overall frontal armour and thus survivability.
Armour type:
- Rolled homogeneous armour (Hull, Cupola doors)
- Cast homogeneous armour (Turret, Hull machine gun area)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 89 mm Front plate 89 + 89 mm Front plate (MG Port) 38 mm (70°) Front glacis 76.2 mm (20°) Lower glacis |
64 mm 76.2 mm Side hatch 38 mm Edges 26 + 38 mm Rear |
50.8 mm 25.4 mm (71°) Bottom |
15.87 mm |
| Turret | 89-104 mm (1°-38°) Turret front 76.2 mm (5°-65°) + 50.8 mm (10°-63°) Gun mantlet |
76-80 mm | 76-80 mm | 35-45 mm |
| Cupola | 19.05 mm | 19.05 mm | 19.05 mm | 19.5 mm Front 25.4 mm Back |
Notes:
- Suspension wheels and chassis construction are 20 mm thick while tracks are 30 mm thick.
- Air inlets have a 63.5 mm plate modelled.

Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- The cheek area of the turret is significantly reduced and well sloped sideways (previously a major weak spot of Churchill III)
- The 75 mm gun offers a significant improvement in firepower
- The M61 APHE shot makes engaging and destroying enemies much easier than with solid shots
- A great gun depression of -12 degrees makes fighting in mountainous terrain easy
- Excellent armour for its BR range; can withstand multiple enemy shots (except the German long 75 mm guns)
- Has smoke grenades to lay a smoke screen
Cons:
- Vehicle difficult to manoeuvre in tight and narrow streets, and with a terrible and slow reverse speed (-3 km/h)
- Slow top speed and poor mobility are inherent weaknesses, requiring extra caution in close quarters engagement.
- No primitive gun stabiliser for the 75 mm gun, sudden stopping of the tank causes the gun to wobble
History
Describe the history of the creation and combat usage of the vehicle 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 vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-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 />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
