Marine Corps F/A-18 Hornet squadron will be the first forward-deployed unit with the AGM-88E. In September 2013, ATK delivered the 100th AARGM to the U.S. Navy. The AGM-88E program is on schedule and on budget, with Full Operational Capability (FOC) planned for September 2014. The AGM-88E was designed to improve the effectiveness of legacy HARM variants against fixed and relocatable radar and communications sites, particularly those that would shut down to throw off anti-radiation missiles, by attaching a new seeker to the existing Mach 2-capable rocket motor and warhead section, adding a passive anti-radiation homing receiver, satellite and inertial navigation system, a millimeter-wave radar for terminal guidance, and the ability to beam up images of the target via a satellite link just seconds before impact. This model of the HARM will be integrated onto the F/A-18C/D/E/F, EA-18G, Tornado ECR aircraft, and later on the F-35 (externally). In September 2015, the AGM-88E successfully hit a mobile ship target in a live-fire test, demonstrating the missile's ability to use antiradiation homing and millimeter-wave radar to detect, identify, locate, and engage moving targets. In December 2019, the German Air Force ordered the AARGM. On August 4, 2020, Northrop Grumman's Alliant Techsystems Operations division, based in Northridge, California, was awarded a $12,190,753 IDIQ contract for AARGM depot sustainment support, guidance section and control section repair, and equipment box test and inspection. On August 31, 2020, the same Northrop Grumman division was allocated roughly $80.9 million to develop new technology for the AARGM. AGM-88F HCSM Although the US Navy/Marine Corps chose the Orbital ATK-produced AGM-88E AARGM, Raytheon developed its own update of the HARM called the AGM-88F HARM Control Section Modification (HCSM), tested in conjunction with and ultimately for the US Air Force. It incorporates similar upgrade features as the AARGM, and although it is not yet listed for export, existing HARM users have shown interest. AGM-88G AARGM-ER The Navy's FY 2016 budget included funding for an extended range AARGM-ER that uses the existing guidance system and warhead of the AGM-88E with a solid integrated rocket-ramjet to double the range. In September 2016, Orbital ATK unveiled its extended-range AARGM-ER, which incorporates a redesigned control section and rocket motor for twice the range and internal carriage on the Lockheed Martin F-35A and F-35C Lightning II; internal carriage on the F-35B is not possible due to internal space limitations. The new missile utilizes the AARGM's warhead and
