The U.S. Navy’s Air Test and Evaluation Squadron VX-9 “Vampires” has been observed testing the RIM-174 ERAM (SM-6) missile on one of their F/A-18 Super Hornets once again. Stationed at Naval Air Weapons Station (NAWS) China Lake, VX-9 operates a diverse fleet including F/A-18E/F Super Hornets, EA-18G Growlers, and F-35C Lightning IIs.
Previously, in 2021, a VX-31 F/A-18F was seen carrying an inert SM-6 without its MK72 first-stage booster, leading to speculation about the missile's potential as a new long-range air-to-air weapon. This idea was reinforced by Raytheon’s classified Long-Range Engagement Weapon (LREW) program for the U.S. Air Force and Navy, which aims to develop advanced long-range air-to-air missile technology. The LREW program incorporates proven components from existing systems with new technologies to enhance performance, involving system design validation, wind tunnel testing, engineering assessments, and kill chain investigations.
Although the LREW project transitioned entirely to the U.S. Air Force in 2019, with Raytheon receiving a contract in 2022, the U.S. Navy has continued its efforts to integrate a long-range air-to-air weapon for its fighter fleet. Recently, a VX-9 Super Hornet was spotted carrying an inert SM-6 missile, as captured by aviation photographer @StinkPlove on social media platform X. The orange and gray SM-6 was mounted on the Super Hornet’s number 7 pylon.
This push for air-launched SM-6 capability aligns with the development of new long-range air-to-air weapons by the PLA Air Force, such as the PL-15 and PL-17, which surpass the range of current U.S. Navy air-to-air weapons. The surface-to-air version of the SM-6 achieves ranges of 130 nautical miles (240 km), with estimates suggesting potential ranges up to 250 nautical miles (463 km) for an air-launched variant. This enhancement would significantly extend the reach of a Carrier Air Wing (CAW), enabling it to engage distant targets more effectively.
The SM-6 utilizes an X-band receiver for guidance, making it compatible with the AN/APG-79 radar on the F/A-18E/F and the AN/APG-81 AESA radar on the F-35C. In operational scenarios, forward-based F-35C fighters could guide the missiles to their targets, while Super Hornets, launching from safer distances, could provide the firepower. The Super Hornets can also transmit fire control data via the Navy’s Naval Integrated Fire Control–Counter Air (NIFC-CA) datalink system.
An air-launched SM-6 capability would add another high-speed, long-range strike option for surface and land targets, enhancing the versatility of the U.S. Navy’s CAWs. This addition to the weapons portfolio would offer more flexibility for time-sensitive land attacks and maritime strikes, expanding the operational capabilities of fighter aircraft.
