Benchmarking Progress On Radar-Killing Missile Program

The US Air Force has issued a request for information to benchmark the progress of the Stand-in Attack Weapon (SiAW) program, a radar-killing missile being developed by Northrop Grumman. The RFI aims to gather information on potential alternatives or improvements to the SiAW, which is intended to strike mobile targets and integrated air defense systems. While the Air Force has stated it is not currently considering canceling the program or replacing Northrop as prime contractor, the move may signal a desire to accelerate development or explore other options. The SiAW program has been in development since 2023, with Northrop Grumman awarded a $705 million deal. The Air Force’s comments on the program were reported by Breaking Defense.
