ALQ-251 RFCM systems aboard AC-130J Ghostrider aircraft are designed to protect against EW systems and radar-guided weapons in contested environments.
The ALQ-251 RF countermeasure (RFCM) system from Northrop Grumman has been delivered to US Special Operations Command (USSOCOM) as part of an AC-130J aircraft upgrade led by Sierra Nevada Corporation.
The ALQ-251 ‘will provide superior situational awareness and protection against electronic warfare systems and radar-guided weapons in contested and congested electromagnetic spectrum environments’, Northrop Grumman noted in a 1 March announcement.
USSOCOM in July 2020 awarded Sierra Nevada Corporation a $700 million contract to act as prime systems integrator for the RFCM upgrade on AC-130J Ghostrider gunships and MC-130J Commando II tanker aircraft, to help protect aircrew from air- and land-based enemy radar and missile systems.
The deal includes RFCM system engineering services, logistics support and spare parts.
BAE Systems was the previous RFCM system provider for the AC-130J and MC-130J, having been awarded a contract in January 2016.
