Stand-in Attack Weapon

U.S. Air Force air-to-surface missile

The Stand-in Attack Weapon (SiAW) is a tactical air-to-surface missile under development for the United States Air Force (USAF) by Northrop Grumman.

## History[edit]

In May 2022, the USAF awarded contracts to L3Harris Technologies, Lockheed Martin and Northrop Grumman to begin the first phase of development for the Stand-in Attack Weapon (SiAW).[1][2]

On 28 September 2023 the USAF awarded a US$705m contract to Northrop Grumman to develop and test the SiAW. The SiAW is intended to attack relocatable targets including theater ballistic missile launchers, cruise and anti-ship missile launchers, GPS jamming platforms and anti-satellite systems. It will have a shorter range than standoff weapons, being fired by an aircraft after penetrating enemy airspace. The SiAW will fit inside the F-35 Lightning II's internal weapon bays. The design leverages work on the United States Navy's AGM-88G Advanced Anti-Radiation Guided Missile - Extended Range (AARGM-ER). The USAF plans to have an operational weapon by 2026.[3][4]
