USS Converse (DD-291) testing a Flettner Rudder

USS Converse (DD-291) testing a Flettner Rudder
Here we see the Clemson class destroyer USS Converse (DD-291) in the Delaware River on 2 May 1927 after tests of the Flettner Rudder. The mechanism is visible on the main deck at the stern. The Fletter Rudder consisted of a large free moving rudder with a much smaller powered rudder in it trailing edge. To move the main rudder, the smaller rudder was turned in the opposite direction. Much less power was needed to control the large rudder than in normal systems.
