The Messerschmitt Me 262 A-1/U4 Pulkzerstörer (lit. "bomber destroyer"), also known as the Narwal (Narwhal), was a prototype interceptor variant of the Me 262 initially conceptualized in 1943. It was specifically ordered by the Luftwaffe to counter Allied bombing raids, as the already heavy four 30 mm MK 103 autocannons were deemed still not enough to "efficiently" destroy a bomber. To accomplish this task, the Narwal was equipped with a large 50 mm Mk 214 autocannon derived from the 50 mm Pak 38 anti-tank cannon, intended to destroy the bomber with few shots. Due to the weapon being overly complicated to produce, along with the need to modify the airframe to endure the recoil of such a large cannon, it underwent refinement until February 1945. During this time, the two prototypes was outfitted with a similar-calibre BK 5 autocannon (that already served with the Me 410 A-1/U4 and Me 410 B-2/U4) as a placeholder until the refined version of the Mk.214 autocannon, now designated Mk.214a, was equipped. The Narwal then underwent testing between March-April 1945. As the war in Europe came to a close, the need for a specialized bomber-hunter version of the Me 262 was deemed unnecessary as it would further drain the already dwindling resources that Germany had left, and as such the aircraft was not accepted for production.
