Description

The Avro Shackleton is the final military version of the venerated Lancaster series of bombers. Developed in 1945 from the now-obsolete Avro Lincoln as an anti-submarine warfare (ASW) and maritime patrol aircraft, the Shackleton features more specialized armaments, such as a naval radar housed inside a distinctive "bulge" on the belly of the aircraft (which currently serve no purposes in-game), removing the tail gunner position in favor of a flexible mount 20 mm Hispano Mk.V autocannons to strafe naval targets, and a more efficient Rolls-Royce Griffin engines powering contra-rotating propellers.

Introduced in Update "Direct Hit". The Shackleton MR.Mk.2 can be best described as a "quirky" version of the Lincoln B Mk II, with overall better mobility and payload, but worse defensive coverage and survivabilty. The plane has an access to some of the most efficient payload available, being capable of taking out 3 bases with the top payload. Due to the powerful Griffon engines, the Shackleton can be played either as a traditional long range bomber by using its decent climb rate or as a fast bomber using its high WEP power.

As with the previous Lancaster family of bombers, the Shackleton has overall good flight performance. The plane is powered by four Rolls-Royce Griffon engines turning contra-rotating propellers, giving the Shackleton a very good thrust and acceleration for its weight, especially with WEP. The plane can also manoever quite well for its size, allowing the pilots to quickly turn the plane around to escape from the enemy, or to adjust the bomb sight for bombing targets.

While the Shackleton has lower wing rip speed at 575 km/h IAS, the plane can retains its speed around 600-650 km/h in a dive quite well. This allows the Shackleton to be used as a fast bomber to dive at an enemy targets. Though a Shackleton pilot should avoid doing snap turns while the plane is at a speed above 500 km/h, as the wings can be easily overloaded and rips from the plane.

The Shackleton has large wings where the fuel tank are located. There are two pilots and eight gunners in total, but only two use turrets, the top gunner and the nose gunner, if the top gunner is taken out the Shackleton becomes much easier to kill. There is only one steel armour plate of 8 mm covering the roof turret gunner. The overall structual stength of the Shackleton were mixed; the plane can endure some fire damage and can put them out using combinations of self-sealing fuel tanks and EFS, yet were incapable of taking many hits from autocannons, especially at the tail and wings.

The Shackleton MR.Mk.2 can be outfitted with the following ordnance:

• 18 x 250 lb G.P. Mk.IV bombs (4,500 lb total)
• 25 x 500 lb H.E. M.C. Mk.II bombs (12,500 lb total)

• 8 x RP-3 rockets + 15 x 1,000 lb M.C. Mk.I bombs (15,000 lb total)

While stock, the Shackleton has poor payload of 18 x 250 lb bombs, which is not enough destroy a single normal base and only sufficient to take one small base in frontline mode.

However, the Shackleton can unlock the 25 x 500 lb payload at rank 2 modification, which actually outclassed the 14 x 1,000 lbs payload found on the Lancaster and Lincoln, due to the doubled explosive mass compared to the similar bomb from its predecessor, while being significantly lighter payload. 10 of these bombs can take out large base and 5 for small base, which means it can take out at least two and a half bases. The bomb's quantity and sizable explosive mass also makes it ideal for carpet bombings.

The 15 x 1,000 lb M.C. Mk.I loadout is ideal to destroy bases and airfields. Only 5 bombs are required to destroy normal bases and 3 to destroy weaker bases. A squad of 3 Shackletons is capable of destroying all bases and the airfield without landing on some maps. Given that most Air RB maps at its BR consist of respawning bases with a prevalence of attackers, you will rarely be able to drop all 15 bombs on bases without having to wait for at least 1 to respawn.

Due to the Shackleton's ASW roles, the plane has a peculiar choice of equipping eight RP-3 rockets on the wingtips. Due to the large wingspan and the size of the plane, the rockets are woefully inaccurate and are best not to equip it.

Turret2 x 20 mm Hispano Mk.V cannon

Ammunition600 rounds

Fire rate750 shots/min

The Shackleton MR.Mk.2 is defended by:

• 2 x 20 mm Hispano Mk.V cannons, nose turret (300 rpg = 600 total)
• 2 x 20 mm Hispano Mk.V cannons, dorsal turret (350 rpg = 700 total)

The Shackleton has four 20 mm Hispano Mk.V autocannons, mounted in a pair of flexible mounts at the nose and a twin mount on ventral position as its defensive armaments. Compared to the Lincoln, the Shackleton's armament layout can be considered a downgrade due to the removal of tail turret, thus making it defenceless against any enemies coming from below.

While the flexible nose guns were intended to be used to strafe at surface targets, it has very little use in-game due to it is treated as a defensive turret and are thus very hard to aim at ground targets. The gun also has limited horizontal traverse and are thus not useful against slow-flying AI-controlled planes in which the guns can be directed at them to shoot them down.

This leaves the ventral twin turrets as the Shackleton's only "real" defensive armament. While the guns are quite accurate and hard-hitting, it only covers the upper part of the plane with blind spots at the rudder and directly behind the tail, thus forcing the pilot to pull the plane's nose up to get the guns on target. The turret can also be easily evaded by simply attacking from below, thus leaving the Shackleton with no way to fight back.

To add insult to the injury, the Shackleton's belt option for the Hispano autocannons were also quite poor. The stock belt is the only belt with tracer rounds, with only half of the belt is composed of a useful HEI ammunition, while other half were taken by tracer and useless pratice rounds. On the other hand, the upgraded belts offers high-penetrating AP rounds and more HE rounds, but lacks tracer rounds entirely. This leave the Shackleton with tough choice of either an easier-to-aim belt with only half the chance of dealing damage, or highly destructive belt that is very difficult to target at an enemy.

Usage in battles

The Shackleton offers a much-needed payload and mobility improvement over its predecessor, the Lincoln B Mk II, at a cost of worse defensive armaments.

Because of the powerful Griffon engines, the Shackleton can climb at a much better rate than the Lincoln. This allows the plane to stay out of most of the enemy fighters, though you would has a chance of facing an enemy interceptor who will usually engages from below i.e. where the Shackleton is at the weakest. Thus, the best defense for the plane is to avoid any engagements all together using the plane's good thrust power to maintain altitude and energy advantage to speed away from pursuing enemy fighters.

Meanwhile, the Shackleton can be employed in a high risk, high rewards fast bombing role. This tactics allows the Shackleton to quickly reaches the base before most enemy arrives and dispatch multiple base using good handling to adjust the bomb aiming. While this may put the Shackleton in a dangerous swarm of enemy fighters, this will also allows the plane to actually fight back as most enemies would usually engage at the higher altitudes where the Shackleton's ventral turret can engage. In addition, in a larger maps, the enemy fighters would took a longer time to reach their base to intercept, thus leaving the base an easy target for you to take before retreating.

Pros and cons

Pros:

• Decent climb rate for a heavy bomber
• Generally good flight performances, with powerful WEP helping the plane to maintain its speed
• Retains energy and handle quite well for a heavy bomber at high speed, making it usable as a fast bomber
• Self-sealing fuel tanks and overall structural integrity make it resilient to fires
• Very heavy bomb load, with more efficient bomb options
• 20 mm defensive cannons are accurate and will destroy most pursuing aircraft

Cons:

• The bomber risks ripping wings when turning at high speeds (~500 km/h)
• No armour, prone to pilot sniping
• Very poor defensive coverage; lacks defensive armament for the belly and tail, and the frontal turret has limited horizontal traverse
• Low durability; its large tail and wings in particular are very vulnerable to autocannons
• Regularly faces enemy interceptors and fighters with high climb rate and powerful armament, including early jets in an unlucky matchup
• 20 mm has no tracer rounds for the more powerful belts, making it difficult to aim

History

Devblog

Following the end of WW2 and going into the Cold War era, submarine development had picked up so much momentum that the previously used submarine counters quickly became obsolete. In addition to this, Britain was faced with a lack of capable long-range maritime patrol aircraft after it was forced to return the lend-lease B-24 Liberator bombers it received during wartime. A stopgap solution in the form of a modified version of the Lancaster bomber was created, but the need for a dedicated maritime patrol aircraft became more and more emphasized in the postwar period.

Development of the Avro Shackleton began in 1945 after the British Air Staff expressed an interest in the conversion of the Avro Lincoln bomber into a general reconnaissance as well as rescue aircraft. As a result, the Avro Type 696 was designed. The Type 696 was primarily based on the Avro Lincoln bomber, but also borrowed some design solutions from the Avro Tudor airliner, of which the latter two themselves were derivative designs of the famous Avro Lancaster. The first prototype, designated Shackleton GR.1, successfully performed its maiden flight in March 1949 and was shortly afterwards ordered into production.

The Avro Shackleton entered service with the RAF in February 1951. The aircraft performed several roles, ranging from its primary role - maritime reconnaissance - over escort and transport duties to search and rescue, whilst being employed all across the globe. However, the aircraft saw numerous modifications during its lifetime, aimed at increasing its capabilities and addressing reliability and structural problems, although at the expense of added weight. The Shackleton and its variants continued to serve throughout the Cold War era, and in the late '80s the Avro Shackleton was finally considered obsolete.
