Northrop Grumman has invested to mature and test its missile design, which meets U.S. Air Force requirements for SiAW and other programs. Harnessing in-house digital engineering capabilities, Northrop Grumman is completing preparations to launch its missile this year.

To address changing mission requirements, the solution features open architecture interfaces which will bridge current requirements with future upgrades.

During Phase 1 of the SiAW competition, the U.S. Air Force intends to align the SiAW missile system technical capabilities to the Air Combat Command requirements and to the Air Force Weapon Government Reference Architecture.

Tasks include the establishment of an integrated digital environment to design, develop, and test the initial increment of the SiAW missile system utilizing a digital engineering methodology and model-based systems engineering best practices.

The Northrop Grumman solution leverages the Navy’s AARGM-ER, engineering, and manufacturing development, low-rate initial production and integration work on the F-35 aircraft.
