About the E-2C Hawkeye
Manufactuer: Northrup Grumann Corporation.
Power plant: Two Allison T-56-A427 turboprop engines.
Horsepower: 5,000 shaft horsepower each engine.
Length: 57 feet 8.75 inches (17.60 meters).
Wingspan: 80 feet 7 inches (24.56 meters).
Height: 18 feet 3.75 inches (5.58 meters).
Radar: Group II AN/APS-145 radar system.
Diameter of the rotodome is 24 feet (7.32 meters)
Nicknames: "Hawkeye"
Primary function: The Hawkeye provides all-weather airborne early warning and command and control functions for the carrier battle group. Additional missions include surface surveillance coordination, strike and interceptor control, search and rescue guidance and communications relay. An integral component of the carrier air wing, the E-2C uses computerized sensors to provide early warning, threat analyses and control of counteraction against air and surface targets.
Operational: First Flight: October 1960. Operational: January 1964
Operators: United States Navy, Republic of Sinapore Air Force, Republic of China Air Force (Taiwan), Japan Air Self-Defence Force, Isreal Defence Force/Air Force, French Naval Aviation, Arab Republic of Egypt, Aviacion del la Armada de Mexico.
Rotodome: One interesting feature of the E-2 is its 24-foot revolving radar dish. The dish rotates at six rpm and can be retracted two feet to facilitate stowage aboard a carrier. The lift produced by the radar dish when the plane is in flight is sufficient to offset its own weight.
Weight Empty: 40,484 lb. (18,364 kg)
Internal fuel: 12,400 lb. (5,624 kg)
T.O. gross weight: 54,426 lbs (24,689 kg).
Maximum cruise speed: 325 knots (480 km. per hour).
Aircraft Ceiling: 30,000 feet (9,100 meters).
Operating Altitude: (unknown)
Endurance: (unknown)
Range: 200 nautical-mile radius with six hours on station ferry range: 1,525 nautical miles
Radar range: The current model operating in the Fleet, the E-2C, is equipped with radar capable of detecting targets anywhere within a three-million-cubic-mile surveillance envelope while simultaneously monitoring maritime traffic. Each E-2C also can maintain all-weather patrols, track, automatically and simultaneously, more than 600 targets, and control more than 40 airborne intercepts.
Armament: None
Crew size: Five: The E-2C flightcrew will normally consist of a pilot, copilot, combat information center officer, aircraft control officer, and radar officer
