U.S. Navy Awards $3.2B to E-2D Advanced Hawkeye
The U.S. Navy has awarded a multi-year contract modification for an additional 24 E-2D Advanced Hawkeye aircraft to Northrup Grumman. Under the US$3.2 billion fixed-price-incentive-firm contract, the company is expected to produce and deliver 24 aircraft by 2026. The contract also includes an option for nine additional foreign military sales aircraft.
The E-2D is the U.S. Navy’s airborne early warning command and control aircraft system, providing expanded battlespace coverage, a wider range of capabilities, and an enhanced ability to work in the littoral and over land. Its two-generation leap in radar technology allows the E-2D to work with the ship, air and land-based combat systems to track and defeat air, ship and cruise missiles at extended range.
The multi-mission aircraft can be used in humanitarian assistance and disaster relief capacity for civilian emergencies, as well as in combat systems.

The computerised radar and electronic surveillance with Friend or Foe Identification System in E-2D provide early warning and threat analysis against potentially hostile air and surface targets. The E-2 is a twin-engine, five crew member, high-wing turboprop aircraft with a 24-foot diameter radar rotodome attached to the upper fuselage. It is one of the best multi-mission platforms capable of coordinating airborne strike, land force support, rescue operations, drug interdiction operations support and managing a reliable communications network between widely dispersed nodes.
According to Jane Bishop, vice president and integrated product team leader, manned airborne surveillance programs at Northrop Grumman, E-2D has continuously demonstrated its strategic value with early warning, and command and control. She is hopeful that under the new contract Northrop Grumman will deliver innovative solutions that will outpace advancing threats over the life of the fleet.
The company has delivered 37 E-2d aircraft to the U.S. Navy to date. In addition to the production and sustainment of E-2D, Northrop Grumman will deliver a series of capability upgrades on the existing units with aerial refuelling capability, which will significantly extend the aircraft’s endurance.
Advanced Hawkeye
The E-2D Advanced Hawkeye features state-of-the-art radar with a two-generation leap in capability and upgraded aircraft systems that will improve supportability, and increase readiness. In August 2003, Northrop Grumman and Team Hawkeye committed to delivering Delta One, the first system development and demonstration (SD&D) aircraft and on August 3, 2007, it delivered on that promise conducting its successful first flight.
Advanced Hawkeye plays a key role in U.S. Navy’s air and missile defence architecture with many new features. Some of the important improvements in E-2D are the new radar featuring both mechanical and electronic scanning capabilities, fully integrated ‘all-glass’ cockpit, advanced identification system, new mission control workstation, and modernised communications and data link suite. These features allow E-2D to have true 360-degree all-weather radar coverage and makes it a true force multiplier and multi-mission flexible platform. The open architecture compliant, commercial-off-the-shelf (COTS)-based hardware and software enable rapid, cost-wise technology refresh for consistent leading-edge mission tools.
Hawkeye Upgrades
Global Positioning System: On February 11, 2019, the U.S. Air Force awarded Northrop Grumman Corporation a US$59 million contract for the engineering and manufacturing development (EMD) phase of the Embedded Global Positioning System (GPS) /Inertial Navigation System (INS)-Modernisation, or EGI-M, technology.
The EGI-M system will support the rapid insertion of new capabilities and adaptability based on unique platform requirements. Additionally, the modernized navigation system will incorporate new generation GPS receivers, which will be capable to securely and accurately transmit the new military signals for space (M-Code). The EGI-M will be integrated into multiple platforms across all of the services and exportable versions will be developed for international customers. The lead platforms for EGI-M are F-22 and E-2D. EGI-M will also comply with the Federal Aviation Administration’s NextGen air traffic control requirements that aircraft flying at higher altitudes be equipped with Automatic Dependent Surveillance-Broadcast (ADS-B) Out transmitter by January 2020.

Aerial Refuelling: The U.S. Navy is expected to field an aerial refuelling (AR) capable E-2D Hawkeye in 2020. With AR, E-2D will be able to remain airborne to the limits of the aircrew and airframe endurance. Aerial refuelling increases the range and persistence of the E-2D Hawkeyes. Under a 2013 engineering, manufacturing, and development (EMD) contract award, Northrop Grumman designed, developed, manufactured, and tested several sub-system upgrades necessary to accommodate aerial refuelling capability.
Production cut-in and retrofit for aerial refuelling programme began after three aircraft were retrofitted for testing in 2018. These retrofits include adding the fuel probe plumbing, formation lighting, long-endurance seats, as well as flight control software and hardware changes. The long endurance seats enhance the field of view in the cockpit and reduce fatigue over longer missions.
