USAF Contracts Northrop Grumman for SiAW Development

Lockheed Martin and L3Harris Also Competing

The US Air Force has issued contracts to Northrop Grumman, Lockheed Martin and L3Harris for development of the Stand-in Attack Weapon (SiAW) missile. Contract period of performance is three months, with three competitive gates for the prime contractors to validate their missile capabilities, under a digital acquisition approach that emphasises agility and innovation.

Northrop Grumman has invested to mature and test its missile design, which meets USAF requirements for SiAW and other programmes. Harnessing in-house digital engineering capabilities, the company 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.

As a missile leader, Northrop Grumman has a proven history of developing and rapidly delivering long range, highly capable and survivable weapons,” said Mary Petryszyn, President, Northrop Grumman Defense Systems. “We continue to advance our offering to stay ahead of threats and help ensure our mission-enabling capability will be technologically mature, tested and affordable.”

During Phase 1 of the competition, the USAF 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, using a digital engineering methodology and model-based systems engineering best practices.

To date, Northrop Grumman has flown and successfully validated its capabilities against relevant, integrated air defence targets. The company will continue to assess its offering through the use of digital engineering, and prove its capabilities with more stressing flight test scenarios, culminating with a missile launch this year. 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. The capabilities demonstrated by the company are relevant, and support rapid fielding across multiple missions and platforms.
