Karabin maszynowy wz. 36

(Redirected from PWU wz.36)

Karabin maszynowy wz. 36, also known as Karabin lotniczy uniwersalny wz. 36 (English: Machine gun Mark 1936 and English: Aerial Universal Machine Gun, respectively) was a Polish 7.9 mm calibre aerial machine gun of the 1930s. It was a further modified version of Karabin maszynowy wz. 33, itself a modification of the successful Ckm wz.30 multi-purpose HMG.

The major differences between wz. 33 and wz.36 included redesigned feeding mechanisms allowing for the weapon to be fed from both sides (and coupled on double mountings). It was fed by belt magazines of 100 bullets each.

Intended to become the main type of aerial machine gun in Polish service both as fixed wing- or nose-mounted and as turret-mounted weapon, due to the introduction of Karabin maszynowy wz. 37 it was to serve only in fixed mountings in such planes as LWS-3 Mewa, PZL.38 Wilk, PZL.46 Sum, PZL.45 Sokół, PZL.48 Lampart and PZL.50 Jastrząb. Nevertheless, a man-operated mounting was also developed and was used in PZL.43 and PZL.43A light bombers used by Bulgarian Air Force.
