The Beriew Be-18 was a Soviet prototype Cold War flying boat. The design of the machine was developed in 1963, but it is difficult to say whether the machine was flown. It can be assumed that its length was to be about 30.1 meters, with a wingspan of about 29.5 meters. The propulsion would be provided by two turboprop engines cooperating with four-blade propellers. The maximum speed would probably oscillate around 500 km / h. The Be-18 aircraft was developed as a development of the Beriew Be-12 military flying boat. It was assumed that several versions of this machine would be created, including: Be-18 P (passenger version), Be-18 LR (military reconnaissance version), Be-18 T (transport version) or Be-18 FK (photo reconnaissance machine). It can be assumed that the Be-18 P version was able to transport from 35 to 40 passengers as well as luggage and mail for a distance of up to 2,000 kilometers. There are many indications that a pressurized or pressurized cabin would be used.
