The Be-12 was powered by 2 x Ivchenko Progress AI-20D turboprop engines mounted high on a high-wing monoplane assembly. The wings were notably cranked upwards from the fuselage in a "gull-wing" type arrangement. As with other flying boat designs, the use of high-mounted wings aided in lift as well as clearing the engines from the surface of the water. To prevent tipping, pontoon floats were affixed under each wing. The Be-12 was typically crewed by four to six personnel. Beyond its water-based landing and take-off, it also held an inherent amphibious quality thanks to its wheeled undercarriage - a feature retained from the preceding Be-10 design. As such, it could function as a traditional land-based aircraft from prepared runways. Beyond that, the Be-12 accommodated a MAD (Magnetic Anomaly Detection) system in the tail, a radar housed in the nose section and a glazed observation position also in the nose.
Dimensions included a length of 98.8 feet, a wingspan of 98 feet, and a height of 26 feet. Empty weight was listed at 52,800lbs with a Maximum Take-Off Weight of 79,200lbs. Performance from the twin-turboprop engines included a maximum speed of 330 miles per hour, a range out to 2,100 miles and a service ceiling of 26,250 feet.
The Be-12 bettered the outgoing Be-10 - which it succeeded in Soviet Naval Aviation service - by improving its operational ranges. Its payload included up to 3,300lbs of externally-held stores in the form of torpedoes, depth charges, mines, or conventional drop bombs.
The series was exported to Egypt, Syria, and Vietnam while ex-Soviet stocks fell to the Ukrainians. Additionally, ex-Soviet Navy models were reconstituted into the reborn Russian Navy after the fall of the Soviet Empire in the early 1990s.
