Northrop Grumman Delivers Stand-in Attack Weapon Test Missile to the US Air Force

LOS ANGELES, November 18. Northrop Grumman Corporation has delivered the Stand-in Attack Weapon (SiAW) test missile, which is designed to verify that the launch aircraft can safely carry and separate the weapon.

SiAW is an air-to-ground weapon that will provide strike capability to defeat rapidly relocatable targets as part of an enemy’s anti-access/area denial environment.

The US Air Force awarded the SiAW contract to Northrop Grumman in September 2023. The company is continuing to develop the weapon, conduct platform integration and complete the flight test program for rapid prototyping and fielding by 2026. For more information about SiAW, click here.
