BRDM-1
The BRDM-1 (Bronirovannaya Razvedyvatelnaya Dozornaya Mashina, Бронированная Разведывательная Дозорная Машина, literally "Armored reconnaissance/patrol vehicle") was an amphibious armored scout car used by Russia and the former Soviet Union. It was originally known simply as BRDM but when the BRDM-2 entered production and service with Soviet Army in 1962, it received the designation BRDM-1. The BRDM (also known as the BTR-40P) first appeared in 1957, and was in production until 1966. Total production was around 10,000 vehicles, less than 600 remain in the reserves of a number of countries.
History
During exploitation of the BTR-40 armoured personnel carrier by the Soviet Army it became apparent that the inability to cross water obstacles was a substantial problem on the modern battlefield. As a result in late 1954 work, led by designer V. K. Rubtsov, began at the A. Dedkov OKB design bureau on a new amphibious version of the vehicle. Intended simply to be an amphibious variant of the BTR-40 wheeled APC, it received the designation BTR-40P.
