variants with their own articles=The Beriev Be-4 (originally designated KOR-2) was a reconnaissance flying boat built to operate from Soviet warships during World War II. Its development was a direct result of the failure of the Beriev Be-2 design. The Be-4 was an elegant, parasol-winged monoplane with a slight inverse-gull wing. The large radial engine was mounted in a nacelle above the fuselage. This aircraft had none of the vices of the Be-2 and was quickly put into production. However, not many had been completed before the fall of Sevastopol and the over-running of the Beriev factory. Production was resumed in 1943 at Krasnoyarsk, which is where most of the roughly 100 examples were constructed.
