Kubus

Kubuś (Polish for "Little Jacob") was a Polish World War II armoured car and armoured personnel carrier (APC), made by the Home Army during the Warsaw Uprising. A single copy was built on the chassis of a Chevrolet truck and took part in the fights. Currently the "original" Kubuś is restored after the war and held in the Polish Army Museum. There is also a full-scale replica built for the Warsaw Uprising Museum. The latter is in perfect condition and frequently takes part in various open-air fests and reenactment shows.

The construction of the original Kubuś took only 13 days from the decision to handing over to fighting units. Work started on 8 August 1944 in a car repair shop belonging to Stanisław Kwiatkowski in Warsaw's borough of Powiśle, at the corner of Tamka and Topiel Streets. The main engineer was Walerian Bielecki (nom-de-guerre Jan), who was also the designer of the car. However, as a matter of fact the car had no design prepared on paper and instead all construction was improvised in situ. The name was taken in an honour of wife of one of constructors (pseudonym Globus) - she had a pseudonym Kubuś (Polish for "Little Jacob", but also the Polish name for Winnie the Pooh) and was killed in early August.

Kubuś was based on the chassis of a civilian Chevrolet 157 truck, license-built in pre-war Poland by the Lilpop, Rau i Loewenstein company. The chassis was fitted with steel plates for protection of the crew. The plates were bolted to a steel frame and then welded together. The armoured car could carry between 8 and 12 soldiers and was armed with a Soviet-built DP machine gun, underground-built K pattern flamethrower and hand grenades, in addition to personal armament of the soldiers.
