GarageImage Stirling B Mk I.jpg

The Stirling B Mk I is a rank III British bomber with a battle rating of 4.3 (AB) and 5.0 (RB/SB). It was introduced in Update 1.55 "Royal Armour".

The Stirling B Mk I plays as a standard long range bomber. Climbing to high altitudes and using alternative routes to bomb targets to prevent engagement is recommended as the Stirling B Mk I likely wont survive any. It is not well defended at all with low calibre machine guns, which is less effective at the battle rating of 4.3/5.0. It is extremely flammable and fragile when engaged with cannons, although it may survive machine gun fire lower than 10 mm calibre.

Survivability and armour

Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.

  • 8 mm Steel plate in the left pilot's seat.
  • 9 mm Steel plate in front of engine cooling systems.


Suspended armament

The Stirling B Mk I can be outfitted with the following ordnance:

  • 27 x 250 lb G.P. 250 lb Mk.IV bombs (6,750 lb total)
  • 27 x 500 lb G.P. 500 lb Mk.IV bombs (13,500 lb total)
  • 9 x 1,000 lb M.C. 1,000 lb Mk.I bombs (9,000 lb total)

Defensive armament

The Stirling B Mk I is defended by:

  • 2 x 7.7 mm Browning .303 machine guns, nose turret (1,000 rpg = 2,000 total)
  • 2 x 7.7 mm Browning .303 machine guns, dorsal turret (500 rpg = 1,000 total)
  • 4 x 7.7 mm Browning .303 machine guns, tail turret (1,000 rpg = 4,000 total)
  • 1 x 7.7 mm Browning .303 machine gun, ventral turret (1,000 rpg)

Usage in battles


The Stirling B Mk I is very large and very heavy. It has multiple loadout options of bombs, which can get 3 bases with its heaviest bombload. This is also the heaviest bombload at its tier.


Its onboard LMG defensive armament most probably will not be effective against targets at BR 4.3/5.0. Defensive armament does not have 360° coverage, although it is somewhat effective against attacks from behind, where you can fire the dorsal/ventral and tail guns in unison.


The Stirling B Mk I has 4 engines with enormous wing surface area, It makes for a good climb rate but it also struggles with heavier bombloads. Fortunately, the control surfaces are extremely large as well, which helps a lot with controlling the plane.


The Stirling has a huge payload but delivering it may be challenging. This is because the plane is very weak for a BR 5.0. Going straight to bomb and enemy base as soon as you spawn is suicide. Keep in mind that if an enemy plane finds you, you are dead. It is much bigger than a Wellington and catches fire easier; a short burst from a Bf 109 or La-7 and you go down in flames. Stay away from any enemy plane if possible as your defensive armament is almost useless and you can only rely on stealth (WWII Stirlings were used primarily on night missions). Depending on the map, you can choose to go at tree top level, or take a long route away from the combat zone, hidden in the clouds. When attacking ground targets at low altitude, pay attention to anti-aircraft guns and trucks, they can set you on fire easily.

Specific enemies worth noting

Any fighter is very dangerous for the Stirling B Mk I. The Bf 109, La-5, La-7, A6M, and the C.205 are the most lethal opponents. If any risk of engagement is present, the player should seek fighter support.


Directly firing and not using any tactics is enough to kill the Stirling B Mk I. Its defensive armament can be ignored, although attacking from the top will minimize damage. Aiming at wings where the fuel tanks are is recommended, as it will most probably result in a fire.

Pros and cons


  • Rear gunner and top fuselage gunner can fire in unison (If the rear gunner gets knocked-out, The top gunner will still be able to defend)
  • Best payload at rank III, enough to destroy 3 bases


  • Not "short" at all
  • Cannot take many hits
  • Flammable
  • Mediocre LMG defence
  • Almost no armour
  • Vulnerable fuel tanks
  • Very bad climb rate with full payload
  • Sways very heavily in RB when trying to climb
  • Huge glass cockpit means near-certain death from head-on attacks


Describe the history of the creation and combat usage of the aircraft 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: 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 === Encyclopedia Info ===, also if applicable).


Excellent additions to the article would be video guides, screenshots from the game, and photos.
