The U.S. Air Force has granted Northrop Grumman an approximately $705 million contract for the Stand-in Attack Weapon (SiAW). This advanced air-to-ground missile is a key component in the transition to the next generation of air power.

SiAW: The Future of Air-to-Ground Missiles

Scheduled for deployment in 2026, this cutting-edge, high-velocity missile is purpose-built to engage swiftly moving targets situated within enemy territory.

The SiAW is designed to be compatible with the F-35A Lightning II Joint Strike Fighter. Its primary mission is to infiltrate and neutralize hostile air defense systems, command-and-control centers, ballistic missile and cruise missile launchers, GPS jamming systems, anti-satellite systems, and other high-priority targets.

Targeting Excellence: SiAW’s Mission and Capabilities

Moreover, SiAW is optimized for tracking and engaging highly mobile targets that can swiftly change their position between identification and engagement, surpassing the capabilities of previous air-to-ground missiles. To achieve this, it employs enhanced sensors as well as a tail-controlled propulsion system.

Furthermore, SiAW incorporates digital engineering and Weapon Open Systems Architecture (WOSA) to facilitate rapid upgrades, ensuring its effectiveness against emerging threats.

SiAW’s Development Timeline

In the upcoming 36 months, the program will encompass a guided vehicle flight test, along with three additional flight tests. Subsequently, SiAW prototype missiles and associated test assets will be provided to the Air Force.

“Northrop Grumman’s SiAW delivers on the Air Force’s desire for its first digital weapons acquisition and development program,” said Susan Bruce, vice president, advanced weapons, Northrop Grumman. “This next-generation missile represents an adaptable, affordable way for the Department of Defense to buy and modernize weapons.”
