ONR awards Lockheed Martin $15.8M to study improvements of E-2D Radar
E-2D Advanced Hawkeye | E-2C, AN/APY-9, Budget/Costs, Specs
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.
Lockheed Martin Airborne Early Warning Radar Helps Coordinate Haiti Relief Effort · Lockheed Martin
Recently Lockheed Martin announced that it had been awarded a
low-rate initial production contract valued at $171.8 million from
Northrop Grumman Aerospace Systems for four AN/APY-9 Airborne Early
Warning (AEW) radar systems and spare parts. Designed and developed by
Lockheed Martin, the AN/APY-9 is a two generation leap-ahead in AEW
radar, and features both a solid-state transmitter with higher power
than its predecessor for extended range, as well as digital receivers to
increase sensitivity. The UHF radar can “see” smaller targets -- and
more of them -- at a greater range, particularly in coastal regions and
over land. Its electronically scanned array provides critically
important, continuous 360-degree coverage. As a new capability, flight
operators also can now focus the radar on select areas of interest. Lockheed Martin expects to produce the APY-9 radar systems for all 75
of the U.S. Navy’s new planned E-2D Advanced Hawkeye aircraft.

The
E-2D Advanced Hawkeye (AHE) program develops, demonstrates, tests, and
procures the replacement of the AN/APS-145 radar system and other
aircraft system components including Cooperative Engagement Capability
Pre-Planned Product Improvement and Dual Transmit Satellite
Communications that modernize the E-2 weapon system to maintain open
ocean mission capability while providing the United States Navy with an
effective littoral surveillance, battle management, Naval Integrated
Fire Control - Counter Air (NIFC-CA) and Theater Air and Missile Defense
(TAMD) capability. Key radar technologies are Space-Time Adaptive
Processing, Electronically Scanning Array, solid state transmitter, high
dynamic range digital receivers and Identification Friend or Foe
(IFF)/radar aperture integration. The resultant detection system will
provide a substantially improved overland performance by correcting
current sensor shortfalls and enhancing all current required mission
areas, while simultaneously contributing to the emerging TAMD mission
requirements. Mode 5/S is an upgrade to the existing IFF System
providing the warfighter positive, secure and reliable identification of
friendly aircraft, surface and sub-surface platforms. Mode 5/S
replaces the National Security Administration de-certified Mode 4 IFF
capability, which is no longer effective or suitable for modern military
operations. Mode 5/S will support the Joint Initial Operational
Capability (IOC) as defined by the Joint Requirements Oversight Council.
The U.S. Navy's Secret Counter-Stealth Weapon Could Be Hiding in Plain Sight - USNI NewsThe key to that capability is the aircraft’s powerful UHF-band hybrid
mechanical/electronically-scanned AN/APY-9 radar built by Lockheed
Martin. Both friend and foe alike have touted UHF radars as an effective
countermeasure to stealth technology.
One example of that is a paper prepared by Arend Westra that appeared in the National Defense University’s Joint Forces Quarterly academic journal in the 4th quarter issue of 2009. “It is the physics of longer wavelength and resonance that enables
VHF and UHF radar to detect stealth aircraft,” Westra wrote in his
article titled Radar vs. Stealth.
