The C-2 Greyhound is a twin-engine cargo aircraft, designed to carry mail and supplies to and from aircraft carriers of the United States Navy. Its primary mission is Carrier onboard delivery (COD).
The fact that this aircraft has four vertical stabilizers is due to aircraft carrier hangar deck height restrictions. Only three of these stabilizers have working rudders. For adequate directional control of an aircraft of this size, a single rudder would have been too tall. It also places the outboard rudder surfaces directly in line with the propeller wash, providing effective yaw control even as the plane's airspeed approaches zero, as during takeoff and landing.
The U.S. Navy celebrated its 100-year anniversary in San Diego, where its aviation program began, in "Parade of Flight" above San Diego Bay Saturday February 12, 189 aircraft, ranging from slow-flying vintage planes to modern supersonic jets, took off from North Island Naval Air Station and paraded along the San Diego Bay Area.
Approximately 75 additional planes were parked at the static display area for visitors' viewing
