[Client Values; Actual values in
Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

The M53/M55 is an American tier 9 self-propelled gun.

SPG on a modified chassis of the M47 medium tank. The prototype was produced in 1952, and in 1956 the SPG entered service in two variants: the M55 for the Army and the M53 for the Marines.

The M53/M55 is an unique vehicle in the American SPG branch. The most noticeable features are the turret and the mobility.

The turret has an impressive gun arc of 60°, which helps aiming without moving the vehicle itself. The mobility is very good, having a high top speed and a nice power to weight ratio. This gives the M53/M55 the mobility to relocate, flee from danger or bring support where needed. Futhermore, the gun has a nice mixture of accuracy, reload, and alpha damage. Also the gun has a good gun depression and elevation in comparison to the other SPG's. The main downsides of the M53/M55 is that it's quite large, which makes it easy to hit and having a bad camouflage. Another downside is when coming from the M40/M43, is that the radioman is replaced by a second gunner, resulting in breaking the Brothers in Arms perk.

The M53/M55 leads to the T92 HMC.

Player Opinion

Pros and Cons

Pros:


  • Gun range: stock: 1400 m, top: 1290 m.
  • Very wide firing arc; gun is mounted on a "pseudo-turret" much like the GW Panther.
  • Very good speed, acceleration, and traverse, inferior only to French artillery.
  • Good mix of accuracy, reload, and alpha, along with high shell arc on the upgraded gun.
  • Upgraded gun weighs less than the stock gun, meaning researching the suspension is not required to mount it.


Cons:


  • Poor alpha damage with the stock gun. It's only competitive against tier 8 and below.
  • Large profile and horrific camouflage.
  • Different Crew setup than the rest of the line (radioman replaced for a second gunner).
  • No longer fires AP rounds on the 8" howitzer.


Performance

Initially, moving from the M40/M43 to the M53/M55 is very disappointing, as you have to re-research the 203mm howitzer, so stock you are a faster-reloading, more mobile M12. When fully upgraded, however, the M53/55 becomes a highly mobile, hard hitting artillery piece that is able to greatly influence the game. It has enough mobility to outrun some slower mediums and is able to easily re-position in order to fire on targets that are safe from other positions. Due to it's outstanding all-around performance, the M53/55 sees use in Clan Wars over the T92, which was rendered obsolete by the Conqueror Gun Carriage.

With the SPG rebalance, the stock gun is a viable alternative to the 203mm. While it features lower alpha damage and pen, the DPM is the same, and the improved rate of fire, aim time, and accuracy may help you keep targets tracked and stunned for longer, allowing your teammates to finish them off.


Early Research

  • Nothing carries over from the M40/M43.
  • The AN/PRC-25 radio carries over from the M44.
  • First, research the 8-inch Howitzer M47, as it is lighter than the stock gun.
  • Next, research the Suspension.
  • Finally, research the Continental AV-1790-7B Engine.

Historical Info

M-55 8-inch Self-Propelled Howitzer (right) with the M53 155mm Self-Propelled Gun

The M55 was an American fully enclosed and armored self-propelled artillery based on the M53 155 mm assault gun. It had a 203.2 mm howitzer which could traverse 30° left or right, carrying only 10 rounds of ammunition. The gun had a maximum range of 16,916 meters (10.51 miles) with a rate of fire of one round every two minutes. The M55 armor was light, 25 mm maximum, but sufficient to protect the crew from indirect artillery hits or small arms fire.

Development history

M53 & M55 self-propelled howitzers were quite unique vehicles. While borrowing the chassis, hull and automotive components of the M46/M47 Patton tanks, its internal arrangement was reversed to accommodate a rear-set fully-enclosed turret emplacement. The engine and transmission were now fitted to the front of the hull (as opposed to the rear) with the driver being relocated to the front-left of the turret (as in the M53). The track-and-wheel system involved seven double-tired road wheels per side along with the drive sprocket which was mounted at the front of the hull. One notable feature of the running gear was its lack of a track idler at the rear which gave the track link system of the M55 a very identifiable quality. Three track return rollers guided the upper track sections. The gunner crew operated under the protection of an enclosed armored structure which provided security against small arms fire or artillery spray as the steel armor protection was 25mm at its thickest. The complete crew numbered six and included the driver, vehicle commander, gunner and at least two loaders. The primary design characteristic of the M55 was its boxy turret emplacement, which was a turret in name only. Traverse was limited to 30-degrees to the left or right and little else, requiring the vehicle to be itself turned in the direction of fire more often than not. The 203mm M47 howitzer was of good strategic value, able to lob all manner of shells at the enemy position up to 17,000 meters.
M55_howitzer,_rear_view. Note the stabilising dozer
However, due to the large projectiles, the rate-of-fire was limited to just one round per two minutes and stowage aboard the vehicle meant that only 10 rounds could be carried - thusly limiting its tactical value (the M53 managed 20 x 155mm shells). Defense was through a Browning .50 caliber M2HB anti-aircraft/anti-infantry heavy machine gun mounted on a pintle at the commander's cupola.


Power for the M55 vehicle was served through a Continental AV-1790-5B 12-cylinder gasoline-fueled engine outputting at 810 horsepower. This was mated to an Allison CD-850-4 transmission system that featured two forward and one reverse gears. The vehicle, therefore, could manage up to 30 miles per hour on ideal surfaces and featured an operational range out to 160 miles. As improvements were brought into the Patton tank lines, the M53 and M53 vehicles adopted some of these measures including the AV-1790-7B engines and CD-850-4B transmissions. Similarly, the original stick steering control arrangement later gave way to a conventional steering wheel design. Some M55s were utilized operational during the American involvement in the Vietnam War (1955-1975) though they were eventually removed from inventory within time. The M53 and M55 shared some commonality of parts themselves, able to utilized the same ammunition racks and M86 gun mounts which made for some logistical friendliness. Beyond its use in the United States military, the Belgian Army became the only other notable operator of the M55 vehicle. The last M55 was retired from active service (with the Belgian Army) in the 1970s.
