From an operating altitude above 25,000ft, the Hawkeye warns the naval task force of approaching air threats and provides threat identification and positional data to fighter aircraft such as F-14 Tomcats. Secondary roles include strike command and control, surveillance, guidance of search and rescue missions and as a relay to extend the range of communications.
The U.S. Navy E-2C Hawkeye is the "eyes and ears" for US Carrier Battle Groups. They are equipped with a long range surveillance radar, and have significant communication capability. The E-2C Hawkeye is normally based aboard aircraft carriers, acting as the airborne "quarterback," or battle manager for the fleet. There currently is one squadron of four Hawkeyes in each carrier air wing (CVW). The E-2C Hawkeye is an all-weather, tactical airborne warning and control system platform.
It provides all-weather airborne early warning and command and control functions for the carrier battle group. With it's distinctive 24 foot diameter rotating radome and more than 12,000 pounds of electronics, the E-2C can monitor 6 million cubic miles of airspace and more than 150,000 square miles of ocean surface for the presence of aircraft, missiles, ships, and fixed targets. The Hawkeye's long-range radar and other electronic surveillance systems can simultaneously detect and track hundreds of ships and aircraft more than 200 miles away.
With its specialized computer and communication equipment, the E-2C can also be used for missions such as air traffic control, surface surveillance coordination, strike and interceptor control, search and rescue guidance and communications relay. Designed and built by Northrop-Grumman Corporation, the has been on active duty with the US Navy since 1973.
