Sukhoi Su-4 Dive Bomber
The Sukhoi Su-4 dive bomber was the first and only retractable-gear monoplane dive bomber adopted by Russian Naval Aviation for carrier-borne use. Designed by the Sukhoi Design Bureau (OKB), the Su-4 first flew in March 1938, and entered service with the Russian Navy in October of 1940. The Su-4 was never more than moderately successful in its intended role, with lackadaisical speed and payload in comparison to designs fielded elsewhere. However, the range was good, making the Su-4 a useful carrier-borne search and antisubmarine aircraft, a role it performed even after dive bombing fell out of favor in Naval Aviation. Although level-flight performance was mediocre, during dive bombing the aircraft behaved in a satisfactory manner.
The Russian VVS (Military Air Forces) also purchased a quantity of Su-4s as land-based dive bombers, although they failed to displace the Ilyushin Il-2 and Il-10 Shturmoviks, and were instead used as target tugs.

Beriev Be-5 Naval Strike Aircraft
The Beriev Be-5 naval strike aircraft entered service with the Russian Naval Aviation forces (AV-MF) in late 1943, displacing obsolete Ilyushin Il-2K "Sturmovik" aircraft. The Beriev functioned primarily as a torpedo bomber, although it could carry bombs and rockets for particular missions.
The aircraft was not particularly advanced for its day, but acquired a reputation for ruggedness and reliability equivalent to the Sturmovik it replaced. Throughout its lifetime, the Be-5's loss rate due to mechanical accidents was 35% lower than any other type of aircraft in the Russian inventory. It also was well-regarded for being extremely hard to stall, and easy to recover. This made it the aircraft of choice for training naval aviators in carrier operation, a role it served until 1959.
The primary version manufactured was the Be-5K, which was designed for carrier operations.
