The United States (US) Army remains committed to modernizing its field artillery formations through the acquisition of mature and available 155mm, self-propelled howitzer systems. Over the past 12 months, the US Army re-evaluated its objectives for modernization and adjusted those objectives to best support the Army Transformation Initiative (ATI). Comprehensive analysis has confirmed the importance of 155mm self-propelled artillery system-of systems to the Army. In the interest of supporting the Secretary of Army’s vision of transformation; SPHS intends to release a Request for Prototype Proposal (RPP) in the Second Quarter of Fiscal Year 2026 for the US Army’s self-propelled howitzer solution to replace the towed M777 howitzers initially within the Stryker Brigade Combat Teams, followed by the Mobile and Infantry Brigade Combat Teams. The Government intends to award one contract to a single vendor via a competitive technical evaluation.

In support of this objective, SPHS will host a virtual Industry Day on or around 21 January 2026 to describe the organizational vision and to field industry questions. In addition to fielding questions on the overall strategy, SPHS will address special topics to orient industry and obtain feedback on the following topics:

1. Intellectual Property

2. Onshoring to the Continental United States (CONUS)

3. Prototype delivery in support of Safety Release testing
