The PB-7 (ПБ-7) is a Soviet amphibious armoured car developed in the 1930s from the PB-4.
The PB-7 was developed for the amphibious reconnaissance role. The PB-7 was developed from the PB-4, with a major redesign of most of the hull and superstructure to improve its swimming capability and reduce overall weight.
The 45mm cannon in the PB-4 was replaced with a new turret fitting a 12.7mm ShVAK aircraft machine cannon, as other vehicles in this role were fitted with 12.7mm or 37mm guns. The penetration power was similar to the 37mm guns in service, so it was deemed an acceptable change.
The swimming ability was improved on the PB-7 by fitting 'all-over' tracks to the rear wheels, which gave the vehicle an appearance of a half-track. These tracks helped the vehicle move through water more efficiently.
The PB-7 entered trials through testing in the field, however the results of these trials have not been recovered. Overall, the PB-7 was not accepted into mass production, as its only improvement over other amphibious light vehicles was that it maintained a higher on-road speed.
