?The M40/M43 has an excellent traverse speed compared to the [[GW Tiger]] and [[Object 212]] and its top speed is good as well. The M40/M43 has a lower damage output than both those SPGs but makes up for this with its mobility, giving it the ability to relocate quickly if it is spotted by enemy tanks. +The M40/M43 has excellent mobility compared to the other hard hitters in tier 8, [[Tank:GW_Tiger_P|G.W. Tiger P.]] and [[Tank:SU-14|SU-14-2]]. It is on the higher end for shell damage in its tier, with higher shell damage than the [[Tank:Lorraine155_51|Lorraine 155 51]] and [[Tank:GB79_FV206|FV207]], tied with the SU-14-2 and only outclassed by the G.W. Tiger P. However, it has lower mobility than the Lorraine 155 51 and FV207. Due to its high damage combined with adequate accuracy, reload, and good mobility when fully kitted out, the M40/43 is arguably the best tier 8 artillery piece, and thus sees Clan Wars use during events with a tier 8 cap. Brothers in Arms and Snap Shot are highly recommended crew skills to train. Also worth mentioning is the lowish 241mm penetration of the AP round, making it unreliable at best, and only worthwhile to use if you intend to troll people, though if you choose to use it, expect to miss many shots and bounce even more.

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.

Player Opinion

Pros and Cons

Pros:


  • Gun range: stock: 1400 m, top: 1330 m
  • Relatively fast and mobile
  • Good horizontal gun arc
  • Good damage for its tier


Cons:


  • Mediocre accuracy and slow aim time (can be mitigated with a strong crew and premium food consumable)
  • Slow RoF
  • Low Camouflage Rating
  • Unreliable AP round on upgraded gun
  • Low vertical shell arc


Performance

The M40/M43 has excellent mobility compared to the other hard hitters in tier 8, G.W. Tiger P. and SU-14-2. It is on the higher end for shell damage in its tier, with higher shell damage than the Lorraine 155 51 and FV207, tied with the SU-14-2 and only outclassed by the G.W. Tiger P. However, it has lower mobility than the Lorraine 155 51 and FV207. Due to its high damage combined with adequate accuracy, reload, and good mobility when fully kitted out, the M40/43 is arguably the best tier 8 artillery piece, and thus sees Clan Wars use during events with a tier 8 cap. Brothers in Arms and Snap Shot are highly recommended crew skills to train. Also worth mentioning is the lowish 241mm penetration of the AP round, making it unreliable at best, and only worthwhile to use if you intend to troll people, though if you choose to use it, expect to miss many shots and bounce even more.


Early Research

  • Both upgrade engines and both upgrade radios carry over from the M12 if researched there.
  • The suspension upgrade is necessary to handle the weight of the top engine and gun.
  • Research the 8 in howitzer ASAP
  • Not necessarily tank research, but train "Brothers in Arms" and "Snap Shot" on your crew. these skills greatly help this artillery piece.

Historical Info

M40 in the US Army Ordnance Museum

The 155 mm Gun Motor Carriage M40 was a US self-propelled artillery vehicle built on a widened and lengthened Medium Tank M4A3 chassis, but with a Continental engine and HVSS (Horizontal Volute Spring Suspension) that was introduced at the end of the Second World War. Equipped with a 155 mm M2 gun, it was designed to replace the earlier M12 Gun Motor Carriage. Its prototype designation was the T83, but this was changed to the M40 in March 1945.

A single pilot vehicle was used in the European Theatre in 1945 by the 991st Field Artillery Battalion, along with a related 8-inch Howitzer Motor Carriage T89, which was sometimes also equipped with a 155 mm barrel.[1] From there, it was deployed during the Korean War.

After World War II, the M40 was used by the British Army, who designated it the 155mm SP M40.


A version on the same chassis mounted an 8-inch (203 mm) howitzer and was designated the M43 Howitzer Motor Carriage. It was standardized in August 1945, 48 were built. The M43 saw action in the Korean War.

Variants

The Army planned to use the same T38 chassis for a family of SP artillery:

  • Cargo Carrier T30- a few built before cancellation in December 1944 to make more chassis' available for GMCs.
  • 8 inch Howitzer Motor Carriage M43- 8 in (203 mm) HMC, standardized August 1945, 48 were built.
