Northrop Grumman has delivered its Stand-in Attack Weapon (SiAW) test missile to the US Air Force, a weapon specifically designed to engage rapidly relocatable threats. This test missile will be used to verify the safe carriage and separation of the weapon from its launch aircraft. The delivery follows a $705-million contract awarded to Northrop Grumman by the US Air Force in 2023 to integrate the new SiAW onto its F-35 combat jet fleet. As part of this agreement, Northrop Grumman is also responsible for testing and ensuring the SiAW’s integration with the fifth-generation fighter, with an initial operational capability target set for 2026.
