About the E-2D Adv. Hawkeye:





The Northrop Grumman E-2C Hawkeye/E-2D Advanced Hawkeye is an all-weather, twin engine, carrier-based, airborne early warning command, control and surveillance aircraft designed to extend task force defense perimeters. The Advanced Hawkeye provides improved battle space target detection and situational awareness - especially in the littorals (close to shore areas). The E-2 is the sister aircraft of the C-2 Greyhound transport aircraft.

The E-2D is powered by two Rolls-Royce T56-A-427A turboprop engines, each rated at 5,100 shp. The aircraft comes with Hamilton Sundstrand (UTC Aerospace Systems) NP2000 eight-bladed composite propellers.

The aircraft first flew on August 3, 2007 and is expected to achieve Initial Operational Capability (IOC) in FY 2015. The E-2D was cleared for full-rate production in February 2013.

Operating from Nimitz Class aircraft carriers - as part of carrier air wings, the E-2C/D provides expanded situational awareness, especially in the area of information operations, where it is responsible for battle management and air and missile defense. Each Nimitz Class carrier has four E-2C Hawkeyes/E-2D Adv. Hawkeyes. The Advanced Hawkeye is the first aircraft in the missile defense network able to detect a cruise missile launched from a ground-based mobile platform. The E-2D will utilize FORCEnet-enabled communications to respond to this time-critical threat and alert CG 47 AEGIS guided missile cruisers of the missile launch. The E-2D provides continuous cueing information until the cruisers can destroy the missile. Simultaneously, collaborating with satellite intelligence, surveillance, and reconnaissance assets, the Advanced Hawkeye will direct Unmanned Aerial Vehicles (UAV) to locate and identify the missile launch platform. The Advanced Hawkeye relays this information to strike aircraft that will then deliver precision-guided weapons to eliminate the missile launcher before it can reposition or launch a second attack.

The E-2D comes with many new features installed, including the Lockheed Martin AN/APY-9 Airborne Early Warning Radar, which provides both mechanical and electronic scanning capabilities. The AN/APY-9 can detect smaller targets (and more of them) at a greater range. The E-2D's radar and identification friend or foe (IFF) system can detect targets at ranges in excess of 345 miles (556 km). The aircraft's electronic support measure system can detect and classify targets at distances beyond radar limits. The onboard communications and data processing subsystems are capable of collecting and distributing tactical pictures and data to command centers and other assets for network-centric operations. The 24-foot rotodome contains a new electronically scanned array, which provides critically important continuous 360-degree scanning (the UHF electronically scanned array antenna was developed by L-3 Communications). Other new features are a fully integrated tactical glass cockpit (Northrop Grumman), an advanced identification friend-or-foe (IFF) system (BAE Systems), a new mission computer (Raytheon), electronic support measures enhancements, and a state-of-the-art communications and data link suite.

The E-2D has a crew of five, including two pilots and three mission systems operators with the option for the co-pilot to act as fourth mission systems operator. Being a carrier-based aircraft, the E-2D is equipped with a tail hook for landings and is capable of using the aircraft carrier's catapults for take-off.

The E-2A Hawkeye (initial model) was developed in the late 1950s/early 1960s - entering service with the Navy in 1964. In 1977, the E-2B replaced the E-1B Tracer.

In August 2013, Northrop Grumman was awarded a $617 million contract for five Full Rate Production (FRP) Lot 1 E-2D aircraft. On July 2, 2014, the U.S. Navy awarded Northrop Grumman a $3.6 billion multiyear contract for 25 E-2Ds. To date, Northrop Grumman has delivered 13 E-2D production aircraft. The DoD procurement objective is 75 aircraft with the last purchase in FY 2021.



Armament/Weapons:

None.



Price/Unit Cost:

The unit cost of the E-2D Advanced Hawkeye is $179.36 million (flyaway cost in FY 2014) of which the airframe and two Rolls-Royce T56 engines make up a total of $95.17 million. The cost of the avionics package amounts to $70.04 million.



Program Cost:

The total procurement cost of the E-2D program is $15.25 billion (estimated by the DoD) + $5.16 billion in research and development (RDT&E) funds, which means the total estimated program cost is $20.41 billion (numbers are aggregated annual funds spent over the life of the program and no price/inflation adjustment was made). This figure excludes military construction (MILCON) costs in support of the program in the amount of $44 million.



Mission/Role:

The E-2D Advanced Hawkeye provides advance warning of approaching enemy surface units and aircraft to vector interceptors or strike aircraft to attack. It provides area surveillance, intercept, strike/air traffic control, radar surveillance, search and rescue assistance, communication relay and automatic tactical data exchange. The E-2D Advanced Hawkeye provides a two-generational leap in radar technology, and will provide the long-range air and surface picture; theater air and missile defense, and is a key component of Naval Integrated Fire Control-Counter Air (NIFC-CA).



FY 2014 DoD Program:

Funds five E-2D Advanced Hawkeye Full Rate Production (FRP) Lot 2 aircraft, associated support, and funds advance procurement for four FY 2015 aircraft. Procurement funds in the amount of $1,267.0M have been allocated to the program.



FY 2015 DoD Program:

Funds four E-2D Full Rate Production (FRP) Lot 3 aircraft in the second year of a Multiyear Procurement (MYP) contract that has a total of 25 aircraft from FY 2014 through FY 2018, associated support, and funds advance procurement for five FY 2016 aircraft (the third year of the MYP). Supports follow-on test and evaluation, trainers, non-recurring engineering for the Identification Friend or Foe (IFF) system and in-flight refueling capability. Procurement funds in the amount of $1,074.4M have been allocated to the program.
