Raytheon AN/APG-82(V)1 AESA Radar
The Radar Modernization Program (RMP) incorporates an APG-82 AESA antenna with more supportable radar electronics. The APG-82 replaces the APG-70 radar currently integrated on the F-15E, improving radar reliability, maintenance and performance while reducing costs. The APG-82(V)1 AESA radar [previously designated AN/APG-63(V)4] is the latest radar advancement for the US Air Force F-15E fleet. The APG-82 uses active electronically scanned array radar technology composed of numerous small solid-state transmit and receive modules. The standard radar, APG-70, is a mechanically-scanned antenna (MSA) housed in the nose of the aircraft. Although the current F-15E radar has undergone numerous updates and upgrades, it is still the same system the aircraft had on its maiden flight. One AESA-equipped F-15E can detect and track multiple targets simultaneously and gain the same battle picture and prosecute the same number of attacks that currently require several mechanically scanned radar assets.
Adding AESA multiplies the effectiveness of the F-15E. Aircraft equipped with the APG-82(V)1 AESA radar can simultaneously detect, identify and track multiple air and surface targets at longer ranges than ever before. The longer standoff range facilitates persistent target observation and information sharing for informed decision making. This superior battlespace awareness supports greater tactical mission capability. The result: greatly increased aircraft-aircrew effectiveness and survivability. The advantage AESA radar has over an MSA is its near-instantaneous ability to redirect its focus from air-to-air to air-to-ground mode. By no longer having to wait for the array to physically move to a new area of interest, the aircrew receives better situational awareness in less time.
The APG-82(V)1 optimizes the F-15E’s multirole mission capability. In addition to its extended range and improved multi-target track and precision engagement capabilities, the APG-82(V)1 offers a more than twentyfold improvement in system reliability over the legacy F-15E APG-70 radar. The new radar works as a plug-in-play system with newer, easily replaceable parts. It's expected to have approximately a 20-fold improvement in aircraft reliability. This phenomenal level of reliability and maintainability will result in significant maintenance cost savings for the U.S. Air Force - the aircraft stays mission-ready. An average failure for the radar component was previously measured in tens of hours and can now be measured in hundreds of hours. The APG-82 has fewer moving parts and the new equipment lasts longer, which cuts down on the time needed for repairs.
In November 2007, Raytheon’s AESA radar was competitively selected for the F-15E radar modernization program. In 2008, the USAF awarded Boeing a $238 million contract to modernize the F-15E radar system. Developmental testing is scheduled to continue through 2012, but the OFP CTF, being a shared unit of the 46th Test Wing and 53rd Wing, is unique in that its members can perform developmental tests while incorporating early operational testing. Officials began modifying a 53rd Wing F-15E with the new radar and they planned to begin some of the operational type of testing as early as March 2011. The next stage of testing for the radar will be conducted by Air Force Operational Test and Evaluation Center officials before being incorporated in all F-15Es beginning in approximately 2014.
By leveraging combat-proven technologies—the APG-79 and APG-63(V)3 AESA radars flying on the F/A-18E/F, the EA-18G and the F-15C platforms—Raytheon delivers a low-risk, cost-effective and superior situational awareness and attack radar to modernize the Strike Eagle. Raytheon’s ground-breaking AESA technology has consistently proven its exceptional performance, reliability and mission capabilities for the warfighter. The APG-79 AESA radar design, extended to the APG-82, is combat-proven on fielded F/A-18s, and it’s being adapted to modernize the Strike Eagle. The AESA is also the radar of choice for the F-15C, F/A-18E/F and EA-18G aircraft. Designed to integrate technology advances and adapt to evolving threats, the F-15 radars can be easily upgraded to add future operational capabilities.
