E-2 Hawkeye Grumman
E-2 Hawkeye
Airborne Early Warning
And Control Aircraft

DESCRIPTION:
Although the US Navy had long desired an airborne surveillance platform, it took several years for electronics to sufficiently decrease in size to be fitted within an aircraft that could operate from an aircraft carrier. Even so, it took several more years for computers to become powerful enough that they could track and process more than a few targets at once. These conditions were finally met, however, culminating in Grumman being named the winner of a Navy contract to develop an airborne early warning and control (AWACS) aircraft.
The Grumman design featured twin turboprop engines fitted beneath a high-mounted wing. The long fuselage housed a crew of five, including three mission specialists, and featured a large rotating radome mounted on a pylon above the wing juncture. To compensate for the airflow around the radome, the tail assembly incorporated four fins on a horizontal tail with significant dihedral. This design, first flown in 1960, was originally known as the W2F-1 but was later redesignated the E-2A Hawkeye before entering service.
The Navy took delivery of 59 E-2A airframes by 1967, but these were quickly upgraded to the E-2B standard with the installation of a more powerful processing computer and inflight-refueling equipment. Shortly thereafter, Grumman began production of the E-2C model with far superior avionics and more powerful engines. These aircraft have been continuously upgraded with new radar and sensors, improved avionics, more powerful processing equipment, and software upgrades allowing the E-2C Hawkeye to track over 250 targets and control 30 interceptors at once.
In addition to protecting the US fleet, the E-2 has also been used in cooperation with law enforcement agencies to interdict drug trafficers. The E-2 has also proven popular with the French Navy and a variety of foreign air forces.
As production of the E-2C has wound down, development of a new variant called the E-2D with improved electronics is underway. The US Navy currently plans to purchase 75 of the E-2D model with deliveries beginning in 2010.
