Navy Northrop Grumman E-2C Hawkeye Airborne Early Warning (AEW) from Naval Air Station Fallon NV

Navy Northrop Grumman E-2C Hawkeye Airborne Early Warning (AEW) from Naval Air Station Fallon Fallon NV Salinas California International Airshow 2012 -10 Full Playlist the Hawkeye will continue in its role as the Navy's primary AEW aircraft for years into the future in the E-2D version. The latest version of the E-2, the E-2D Advanced Hawkeye, is currently under development and the first two aircraft, "Delta One" and "Delta Two" remain 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 AN/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 either one of the pilots to act as a Tactical 4th Operator, who will have access to the full range of the mission's acquired data. The E-2D's first flight occurred on 3 August 2007.[6] On May 8, 2009, an E-2D Advanced Hawkeye used its Cooperative Engagement Capability system to engage an overland cruise missile with a Standard Missile SM-6 fired from another platform in an integrated fire-control system test.[7] Deliveries of initial production E-2Ds to Navy began in 2010.[8] On 4 February 2010, Delta One conducted the first E-2D carrier landing aboard the USS Harry S. Truman as a part of carrier suitability testing.[9] On 27 September 2011, an E-2D was successfully launched by the prototype Electromagnetic Aircraft Launch System (EMALS) at Naval Air Engineering Station Lakehurst.[10][11] AN/APY-9 (United States), Airborne surveillance, maritime patrol and navigation radars Type 300 MHz to 3 GHz band Airborne Early Warning and Control (AEW & C) radar. Description Designed for installation aboard the E-2D Advanced Hawkeye AEW & C aircraft, the Lockheed Martin AN/APY-9 (formerly known as the Advanced Hawkeye Radar - AHR) is an electronically/mechanically scanned AEW & C radar that is described as being 'two generations' ahead of the AN/APS-145 radar installed aboard E-2C/E-2C Hawkeye 2000 platforms and as weighing approximately 998 kg. Other system features include:digital beam forming and excitationSpace-Time Adaptive Processing (STAP)use of monopulse techniques (to improve accuracy)in-beam stagger (to eliminate blind speeds)simultaneous air and sea surface target detectionuse of an open, commercial-off-the-shelf architecture (with modular hardware design)use of a solid-state, silicon carbide-based transmission chainported functionality (maintaining domain knowledge)use of an 'advanced' detection data processor (based around CSP Inc FastCluster 2942 blades and offering increased time on threat, flexible beam management and 'enhanced' target tracking)use of an L-3 Communications Randtron Antenna Systems-sourced Rotodome Antenna Group (RAG)use of an Applied Aerospace Structures Corporation (AASC)-sourced composite rotodomeuse of Northrop Grumman-sourced solid-state power amplifiersuse of a Raytheon-sourced, low-noise, digital receiveruse of a BAE Systems-sourced, co-aligned, active scanning array, Identification Friend-or-Foe (IFF) interrogator.Looking at some of these in more detail, the AN/APY-9's RAG incorporates an 18-channel Advanced Detection System-18 (ADS-18) antenna and a 36-element IFF array, with the whole being housed in the cited AASC rotodome. Here, the ADS-18 antenna is scanned electronically in elevation and both electronically (offering instantaneous 120° sector coverage) and mechanically in azimuth and makes use of an 18-channel rotary coupler as the interface between itself and the radar's inboard electronics.
