E-2D Advanced Hawkeye:
The latest version of the E-2, the E-2D Advanced Hawkeye, is currently under development. The first two E-2D aircraft, "Delta One" and "Delta Two" are in flight testing and several other aircraft are currently undergoing Initial Operational Test and Evaluation with Test and Evaluation Squadron One at NAS Patuxent River. The E-2D features an entirely new avionics suite, including the new APY-9 radar, radio suite, mission computer, integrated satellite communications capability, flight management system, improved T56-A-427A turboprop engines, a new tactical glass cockpit and the potential capability for air-to-air refueling. The APY-9 radar features an active electronically scanned array, which adds electronic scanning to the mechanical rotation of the radar in its radome. The E-2D will include provisions for the copilot to act as a "Tactical 4th Operator" (T4O), who, by reconfiguring his main cockpit display to display radar, IFF, and Link 16 (JTIDS)/CEC, will have access to the full range of the mission's acquired data. The E-2D's first flight occurred on 3 August 2007. On 8 May 2009, an E-2D Advanced Hawkeye used its Cooperative Engagement Capabilitysystem to engage an overland cruise missile with a Standard Missile SM-6 fired from another platform in an integrated fire-control system test.These two systems will form the basis of the Naval Integrated Fire Control – Counter Air (NIFC-CA) when this is fielded in 2015. The USN is investigating adding other systems to the NIFC-CA network in the future.
The APY-9 radar of the E-2D has been suspected of being capable of detecting stealth aircraft. Fighter-sized stealth jets are typically optimized to defeat high frequencies like Ka, Ku, X, C, and parts of the S-bands. Small stealth aircraft do not have the size or weight allowances for all-spectrum low-observable features, which leaves them vulnerable to detection by the APY-9's UHF-band radar. This could give the U.S. the ability to detect foreign fifth-generation fighters like the Russian Sukhoi PAK FA and the Chinese Chengdu J-20 and Shenyang J-31. Although UHF radars have historically had resolution and detection issues that made them ineffective at providing accurate targeting and fire control, Northrop Grumman and Lockheed claim to have solved these shortcomings in the APY-9 through a combination of advanced electronic scanning together with enormous digital computing power in the form of space/time adaptive processing. According to the Navy's NIFC-CA concept, the E-2D could act as a sensor to guide the fleet's weapons onto targets beyond the launch platform's detection range. Therefore, it could direct AIM-120 AMRAAM and SM-6 missiles to intercept stealth aircraft that other aircraft or ships would not otherwise be able to locate.
The APY-9 radar onboard E2D Advanced Hawkeye features an active electronically scanned array. Advanced electronic scanning with enormous digital computing power is added to the mechanical rotation of the radar it its radome. Some sources report that it increased the area an aircraft can monitor by 300%. It is also reported that this radar is capable of detecting stealth aircraft.
This could give the US Navy the ability to detect foreign fifth-generation fighters such as the Russian Sukhoi PAK FA and Chinese Chengdu J-20 and Shenyang J-31, as well as stealthy bombers, that are currently being developed.
If this truly haapens this means all the investment of Russia and China got invain.
