The Lancaster B Mk I is a rank IV British bomber with a battle rating of 5.0 (AB), 5.3 (RB), and 5.7 (SB). It was introduced in Update 1.43.
The Avro Lancaster B Mk. I is a long-range heavy bomber optimised for destroying stationary targets such as pillboxes, bases, and airfields with bombs from high altitude.

Usage in battles
The Lancaster carries the heaviest bomb load of any bomber before the American Boeing B-29 Superfortress, at a fantastic 14,000 lb (6,363 kg), and the heaviest of any British bomber in the game. It can quickly end games if left to go about its business. The Lancaster also has relatively good performance and agility for a four-engined heavy bomber, significantly better than both the American B-17 and B-24 bombers.
Unfortunately, the Lancaster is extremely vulnerable if intercepted by enemy fighters. Its defensive armament consists only of .303 in Browning machine guns; while they have a high rate-of-fire, they are not very lethal to enemy fighters outside of a lucky fire set by the incendiary bullets. In addition, the Lancaster has no ventral turret covering attacks from below due to H2S radar unit (a useless feature in the game). The aircraft itself is not very durable as well and is extremely vulnerable to cannons of 20 mm calibre and larger.
The safest way to use this bomber is to attack bases from around the map. Do a big circle-around, go to the corner, and aim the nose to the remaining enemy bases. Side climbing is not recommended because of the Lancaster's terrible climb rate; not to mention the ease that enemy fighters like German and American ones can easily reach the bomber even at 7,000 metres altitude. Instead stay between 2,500 and 4,000 metres and build up speed. Use the Lancaster's amazing payload and drop three of the 1,000 lb bombs onto each base. In the airfield bombing scenario, get altitude not less than 3,000 meters and drop all the bombs onto the main runway for better accuracy. Try to stay near friendly fighters for air cover.

Pros and cons
- Massive bombload of up to 6 tons
- Powerful Merlin engines providing good performance
- Excellent handling and manoeuvrability
- Has a total of 4x 7.7mm MG facing upper rear area which can be lethal to some targets with careful aiming
- 4 engines means that it can maintain flying ability despite damage to some engines
- H-tail means that if one rudder is shot off, the other one still works
- Very low durability
- Is a big and slow target
- No armor plates protecting gunners
- Pathetic defensive armament due to their small caliber and bad damage. Cannot effectively hurt heavily armored interceptors such as Me 410.
- No turret coverage for the belly
- Easily damaged elevators and tail controls
The Lancaster first Lancasters were built and designed by A.V.Roe and Company (or Avro) as a long-range heavy bomber. It was developed as an "upgrade" from the Avro Manchester which was disliked by crews for its difficulty to fly and underpowered engines.
The Lancaster was designed by Roy Chadwick and first flew on 9th January 1941; entering service in 1942. It was produced by Avro, Armstrong Whitworth, Austin Motors, Metropolitan-Vickers, Vickers Armstrong and Victory Aircraft (for the RCAF)
The Lancaster's long, unobstructed bomb bay enabled it to carry the largest bombs the RAF used (including, 4000, 8000, 12,000 and - when modified - 22,000lb bombs). Because of this, it soon became the most widely used British bomber of the 2nd World War.
No. 617 squadron famously used modified Lancasters during Operation Chastise in raids dams in the Ruhr Valley using Barnes Wallace's Upkeep Mine (or "Bouncing Bomb" as it became known as). This gave 617 squadron the nickname "The Dambusters", sparking the creation of a film by the same name.
With RAF Bomber Command's focus being centred on the strategic bombing campaign against German industry, the RAF desperately required a force of heavy bombers to increase the capability provided by their medium bomber fleet. A twin engine Avro Manchester bomber was converted to be powered by four engines and first flown in January 1941. This and subsequent prototypes were deemed to be so successful that the first production variant of the new bomber, now named the Lancaster, was flown in October 1941.
Powered by four Rolls Royce Merlin XX engines rated at 1280 hp, (later upgraded to Merlin 22 or 24s) the Lancaster B.I was capable of reaching speeds of up to 275 mph. With a standard fuel load it could carry 10,000 lbs of bombs over 1000 miles. The maximum ordinance capacity of the Lancaster was one of the highest of any heavy bomber in World War II: 14,000 lb (6,356 kg). Besides standard bombs, the aircraft could carry an 8,000 lb (3,632 kg) "blockbuster" or two 4,000 lb (1,816 kg) high-explosive "cookie" bombs. Special modifications of the bomber could carry even larger bombs, such as the 22,000 lb 'Grand Slam' bomb. For defence, the Lancaster had eight 0.303 inch Colt-Browning Mk.II machine guns located in three turrets: two guns were located in the nose, two in the dorsal turret, and four in the tail turret. This defensive armament was considerably lighter than that of the Lancaster's US counterparts; it relied on darkness for protection rather than firepower. However, even though on paper the Lancaster was an impressive strategic asset, it still had its weaknesses: whereas the Halifax and Stirling could both claim a crew survival rate of 25% in the event of destruction, the Lancaster could only claim a survival rate of 15% for its crews. 58% of all RAF Lancasters were destroyed in combat; a higher loss percentage than any other British aircraft during the entire war.
The Lancaster was first used operationally in March 1942 by No. 44 Squadron. It soon became the backbone of RAF Bomber Command's offensive against the heart of Germany, but was also used against targets all across occupied Europe. The majority of Lancaster operations took place at night due to RAF Bomber Command's policy of night bombing whilst the bombers of the United States Army Air Force tackled targets by day. The Lancaster became legendary on the night of May 17th 1943 when bombers of No 617 Squadron breached the Mohne and Eder dams in Germany with Barnes Wallis' genius 'bouncing bomb'. Lancasters of Nos 9 and 617 Squadrons also sank the German battleship 'Tirpitz' with 12,000 lb 'Tallboy' bombs, also designed by Wallis.
Over 3400 Lancaster B.Is were manufactured between November 1941 and March 1946, making it the most numerous of the Avro Lancaster variants. In addition to RAF operations, the Lancaster was also used by the RAAF and RCAF.
