The Bishop is a [[英國|]] tier 5 自走炮.

以 Valentine 戰車作為基礎開發的車輛。標準炮塔由一座配備著 25 磅榴彈炮的盒形戰鬥室所取代。由於炮管仰角較低(15 度),最大射程只有 5,800 公尺,這只有它在牽引狀態下射程的一半遠。此自走炮投入了北非、西西里、以及義大利南部的戰鬥。根據各種消息來源指出,一共生產了 80–100 輛。

The Bishop feels like a major leap back after the versatility of the Birch Gun; you no longer have a full traversible gun mount, but are forced to deal with a very narrow gun traverse; it has a pitiful range for both guns; and it has a fatally tall silhouette. Its saving grace, however, is better protection and HP than its predecessors, being based on the hull of a Valentine, and its second gun is reasonably better than the 25-pounder. Play the Bishop like an SU-5; move up with the rear lines of your team, and bombard targets of opportunity. Even if you are spotted, you can survive a decent amount of fire while retreating.

The Bishop leads to the FV304.

Player Opinion

Pros and Cons

Pros:


  • Gun range: stock: 1050 m, top: 500 m
  • Good aim time
  • Decent rate of fire
  • Very accurate with top gun
  • Shell travels at a very high arc, making hitting enemies behind cover easier



Cons:


  • Stock gun has terrible elevation on flat terrain, you must use an upward slope to increase gun range and hence relies on map terrain.
  • Poor alpha for stock gun
  • Superstructure is not as well-armoured as the hull
  • Slow and sluggish
  • Low shell velocity, even for arty



Performance

The stock gun's poor range is actually due to the gun elevation rather than the gun's actual range. This also has the other effect of its shells travelling in a low arc, thus lowering damage. Thus, one way to get around these is to either move up with the team, or find an upward slope to position yourself. Having a high silhouette sometimes discourages the former, so it depends on how much risk the player is willing to take.

While the 25 pounder stock gun is not much different from the Birch Gun, the 4.5inch howitzer offers much more damage, but at the expense of not being able to equip AP ammo. Its shell trajectory is also noticeably lower. The heavy armour (for an arty) and high HP pool comes in handy when defending yourself in close quarters, although the slow traverse hinders that. The tall mounting of the gun lets you fire over low obstacles, making hull down an option.


Early Research

  • If you came from the Birch Gun, the WS No. 19 Mk. III Radio carries over. Mount it immediately. You should first research the Bishop suspension, followed by the engines.
  • If you came instead from the Valentine, the GMC 6004 6-71A Engine and WS No. 19 Mk. II Radio carry over. However, only the radio can be mounted. You should first research the Bishop Suspension, followed by the WS No. 19 Mk. III Radio.
  • Finally, research the Q.F. 4.5-in. Howitzer.

Historical Info

Bishop in the Western Desert, September 1942

The Bishop was a British self-propelled artillery vehicle based on the Valentine tank. A result of a rushed attempt to create a self-propelled gun armed with the 25 Pounder gun-howitzer, the vehicle had numerous problems, was produced in limited numbers and was soon replaced by better designs.

Development history

The rapid manoeuvre warfare practiced in the North African Campaign led to a requirement for a self-propelled artillery vehicle armed with the 25 pounder gun-howitzer. In June 1941 the development was entrusted to the Birmingham Railway Carriage and Wagon Company. A prototype was ready for trials by August and 100 were ordered by November 1941.[1] The result was a vehicle designated Ordnance QF 25-pdr on Carrier Valentine 25-pdr Mk 1 and universally known as Bishop. The Bishop was based on the Valentine II hull, with the turret replaced by a fixed boxy superstructure with large rear doors. Into this superstructure the 25 pounder gun-howitzer was fitted. As a consequence of the gun mounting the resulting vehicle had very high silhouette, a disadvantage in desert warfare.[1] The maximum elevation for the gun was limited to 15 degrees, lowering the range considerably to about 6,400 yards (about half that of the gun on its wheeled carriage), the maximum depression was 5 degrees and traverse 8 degrees. In addition to the main armament the vehicle could carry a Bren light machine gun. By July 1942 80 Bishops had been built, and as the last 20 were being built an order for a further 50 was placed, with an option for a further 200, but the tender was abandoned in favour of the American M7 105 mm SP gun.

Combat history

The Bishop first saw action during the Second Battle of El Alamein in North Africa and remained in service during the early part of the Italian Campaign. Due to the aforementioned limitations, compounding the Valentine's characteristic slow speed, the Bishop was poorly received almost universally. In order to compensate for insufficient elevation, crews would often build large ramps out of the earth - running the Bishop onto these tilted the whole vehicle back effectively gaining extra elevation for the gun and increasing its maximum range. It was replaced in service by the M7 Priest (105 mm) and Sexton (25-pounder) when those became available in sufficient numbers, and surviving Bishops were diverted for artillery use.
