Description

The Gun, Air Defence Artillery, Self-Propelled, 40-mm, M247 is a Rank VI American self-propelled anti-aircraft gun with a battle rating of 8.0 (AB/RB/SB). It was introduced in Update 1.81 "The Valkyries".

General info

Survivability and armour

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat?

If necessary use a visual template to indicate the most secure and weak zones of the armour.

Mobility

Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability as well as the maximum speed forward and backward.

Armaments

Main armament

Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.

Additional armament

Some tanks are armed with several guns in one or more turrets. Evaluate the additional weaponry and give advice on its use. Describe the ammunition available for additional weaponry. Give advice on how to use them and how to fill the ammunition storage. If there is no additional weaponry remove this subsection.

Machine guns

Offensive and anti-aircraft machine guns not only allow you to fight some aircraft, but also are effective against lightly armoured vehicles. Evaluate machine guns and give recommendations on its use.

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 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:

  • Twin L/70 40mm Bofors guns have a better rate of fire compared to the M42 Duster.
  • The 40mm's pose a serious threat to lightly-armored vehicles.
  • Uses the M48 Patton's hull (armor included) = one of the best-protected SPAA in the game.
  • Benefits in RB from aim assist thanks to the radar.

Cons:

  • As with all high-rank SPAA, very thin turret armor; a shell strike could instantly end the vehicle.
    • Turret is also vulnerable to strafing aircraft + rockets.
  • Armor advantages are nullified due to the inclusion of the Hull Break mechanic

History

Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an 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>, as well as adding them at the end of the article.

Media

An excellent addition to the article will be video guides, as well as screenshots from the game and photos.
