The Be-6 was a Soviet multi-purpose flying boat designed with the intent of carrying out various maritime missions. The primary purposes for which it was designed were anti-submarine warfare, transport operations, and reconnaissance missions. It was developed in the late 1940s by Beriev OKB and first flew in 1949. The Be-6 was equipped with powerful ASH-73 engines and a large fuel capacity, allowing it to fly for an extended period of time and possibly cover more than 4,000 kilometres without refuelling. It was remarkably well protected for its time, with five powerful NR-23 cannons mounted in the nose and tail turrets, providing effective defense against possible aerial threats. The aircraft served for quite a long time, considering the rapid technological advancement during that era, and wasn't retired until the late 1960s.

The Be-6 was introduced as a premium pack in Update 1.71 "New E.R.A" and was discontinued from the store after the 2018 Victory Day sales, but returned during War Thunder's 6th Anniversary as a premium purchasable with Golden Eagles. One of its most notable features is its defensive armament, which consists of five NR-23s, making it one of the most heavily armed bombers in the game. Furthermore, its maximum payload can take out two bases in air realistic battles, which is quite impressive given its other capabilities.
