E-2 HawkeyeE-2 Hawkeye

The E-2 Hawkeye, produced by Grumman, first took to the sky in 1960. The aircraft, virtually unchanged in outward appearance from the original model, continues to be produced today. Flying from its aircraft carriers, it is the primary surveillance aircraft of the U.S. Navy.

The most prominent feature of the E-2 Hawkeye is its huge radome that is its primary means of information gathering.  Inside the aircraft are a host of computers and electronics equipment. With these, information can be relayed through orbiting satellites to ships, other aircraft, and shore based stations. The Hawkeye essentially functions as a carrier borne AWACS aircraft.

E-2 Hawkeye aircraft have had numerous upgrades through the years. Except for its antennas, the most noticeable external aircraft upgrades are its eight blade props. Newer engines are more powerful and efficient.

Inside the E-2 Hawkeye is a new all glass cockpit. Computer systems have larger, clearer displays, more memory, more functions, are faster, and more powerful. Radars have been replaced and upgraded as technology has improved. We are told that the latest Hawkeye aircraft are capable of tracking and providing intercept data to an infinite number of aircraft or surface targets within their Lockheed Martin AN/APY9 four hundred plus mile radar range.

U.S. E-2 Hawkeye aircraft have served over Vietnam, Libya, and Iraq. The U.S.C.G. also flew the aircraft.

The U.S. Navy has ordered an additional 75 Grumman E-2 Hawkeye aircraft. They anticipated their continued use through 2050.  However military budget cuts may affect their procurement.

The latest E-2 Hawkeye model is the E-2D. It has the new AN/APY-9 radar, and mission computer, an upgraded communications suite with integrated satellite communications, a new flight management system, avionics and electronics which enable greater real time threat evaluation, missile defense, and asset coordination for both terrain and maritime use.  Newer E-2D models are built with air-to-air refueling capability and have improved engines.  The Navy has instituted a program to eventually fit all E-2 Hawkeye aircraft with mid-air refueling capabilities.

Feb. 6, 2019: Japan is upgrading their nine E-2 Hawkeye aircraft with the instillation of the Multifunctional Information Distribution System/Joint Tactical Radio System.  The system is a four-channel radio that runs the Link 16 waveform and up to three additional communication protocols, including the Airborne Networking Waveform.  The new system will occupy the same space as its predecessor system without increased weight or power consumption. Installations are expected to be completed by June of 2020.

April 12, 2019:  U.S. Navy orders 24 E-2 Hawkeye aircraft from Northrop Grumman for US$3.2 billion.  Deliveries are expected to be completed by August of 2026.

July 11, 2019: Northrop Grumman has received a contract in the amount of US$11,063,832 for E-2 Hawkeye aircraft power amplifier modules. Oct. 30, 2022 is the latest delivery date.

July 11, 2019: Northrop Grumman is getting US$17,045,952 for E-2 Hawkeye high voltage power supplies. Oct. 30, 2021 is the expiration date.

Oct. 1, 2019: Northrop Grumman is awarded a US$1.4 billion contract for long lead parts engineering for the production and delivery of nine Japan configuration E-2 Hawkeye aircraft.

Dec.  30, 2019: The Naval Air Warfare Center Aircraft Division awarded North Star Scientific, Kapolei, Hawaii, a US$11,955,975 order. "This order continues research and development efforts under Small Business Innovation Research Phase III topic N06-125 entitled "L-Band Solid-State High Power Amplifier for Airborne Platforms.  Additionally, it provides for the production and delivery of 55 Link-16 compatible high power amplifier Multi-Functional Information Distribution Systems – Joint Tactical Radio Systems in support of the E-2 Hawkeye aircraft for the Navy (35), Air Force (3) and the government of Japan (17)." Work is expected to be completed in December of 2021.

A total of over 300 E-2 Hawkeye aircraft have been produced to date. Over 100 have been acquired by U.S. allies around the world.
