Key point: The Navy must pay attention to this threat.
In 2006, Iranian television showcased a peculiar sea-skimming flying boat, and four years later Tehran triumphantly announced it had three squadrons of them serving in the Iranian Revolutionary Guard Corps Navy. News commentators boasted it was one of the few countries to “design and produce such advanced flying boats,” which is technically true.
The blue-painted Bavar-2 flying boats seen in this video are examples of Ground Effect Vehicles, also known as ekranoplans, sea skimmers, or Wing-In-Ground vehicles. Basically, these are designed to fly at very low altitudes by capitalizing on “ground effect,” the phenomenon in which wing surfaces encounter less drag the closer they are to the surface. After generating lift through speed during takeoff, GEVs can stay airborne as long as they remain within that low-altitude envelope. This makes them more applicable to maritime operations, where inconvenient mountains are scarce.
