Overview
- An inert Stand-In Attack Weapon was released from an F-16 to verify safe separation, aerodynamic behavior, and flight characteristics.
- Engineers will use the results to refine integration models for multiple aircraft, including internal carriage on the F-35.
- SiAW remains in Phase 2 under the Middle Tier Acquisition pathway, with a guided flight test planned before additional trials and prototype deliveries.
- The Air Force is targeting initial operational capability as early as 2026, with the F-35 as the first platform and later integration planned for F-15E/EX and potentially B-21.
- Designed for time-sensitive, high-value targets in A2/AD environments, the missile employs digital engineering and an open architecture, and its speed has not been disclosed by Northrop Grumman.
