F-15E demonstrates new display system



Boeing demonstrated an improved display computer system on a US Air Force F-15E Strike Eagles earlier this month, uniting the host of upgrades the service will implement on its F-15Es and F-15Cs.

On 8 July , the F-15E recorded its first flight with the Advanced Display Core Processor. The high-speed processor can handle new capabilities on the fighter including a long-range infrared search and track capability and an improved electronic warfare suite called the Eagle Passive/Active Warning Survivability System, a July 20 air force press release states.

Last August, the Defense Department also awarded a contract to IEE to upgrade the cathode-ray tube displays on the F-15E to a modern multi-purpose display.

Boeing is equipping the improved F-15E with the Raytheon APG-82(V)1 active electronically-scanned array (AESA) radar, friend or foe identification and a joint helmet mounted cueing system (JHMCS). That technology represented an impressive improvement for the fighter jet, but their full capability could not translate to the pilot without new displays and processors.

AN/APG-82(V)1 AESA Radar


Radar: It is one of the most important differences between the F-15E and F-15SE models. The F-15SE is equipped with Raytheon’s APG-82 radar, the newest of their ultramodern AESA line. Raytheon’s AESA radar versions got a bit confusing in the last years. APG-63(V)4 is yet another improved version of the APG(V)3 (the same radar that can be found in the F-15K Slam Eagle or in the F-15SG), but got a new designation: it’s officially called APG-82, mainly because USAF has selected this radar for its F-15E Strike Eagle radar modernisation programme. This new radar combines the F/A-18E/F Super Hornet’s APG-79 forward antenna with a newly developed backend processor unit derived from the APG-63(V)3. Its designation number is 1 greater than APG-81, theJSF‘s intended AESA radar unit developed by Northrop Grumman, which might come handy for Raytheon for marketing purposes. Source @f-15e.info

Digital Electronic Warfare Suite (DEWS)

Electronic Warfare: Instead of the TEWS used in the Strike Eagle, the F-15SE features a digital electronic warfare system (developed by BAE Systems), dubbed as DEWS. DEWS was developed by leveraging F-22 and F-35 EW program results and replaces 4 legacy systems of the Strike Eagle. It is fully digital (hence its name) and works in close integration with wideband RF systems, including the APG-82 AESA radar, giving the jet a very sharp edge in the electronic warfare arena.

DEWS offers full quadrant detection and response control, containing aft receiving antennas on top of the tails, aft RF transmitters and antennas built in the tailbooms, forward RF transmitters and antennas built in the leading edge of the wing roots, forward receiving antennas built in the wingtips and a low band Rx knife antenna placed on the underbelly of the jet below the cockpit.

DEWS includes a digital RWR, digital jamming transmitter, ICS and an interference cancellation system. According to Boeing, the system enables the Silent Eagle to jam enemy radars while its own radar and RWR continues to operate. Source @f-15e.info
