(DRAFT) Request for Prototype Proposal_181115DEC25.docx

The document is a Draft Request for Prototype Proposal (RPP) related to the U.S. Army's Self-Propelled Howitzer-Modernization (SPH-M) Mobile Tactical Cannon (MTC) program. The Army intends to release a competitive solicitation in the Second Quarter of Fiscal Year 2026 to replace towed M777 howitzers with a new 155mm self-propelled howitzer system, initially targeting Stryker Brigade Combat Teams and subsequently Mobile and Infantry Brigade Combat Teams.

The procurement strategy includes a virtual Industry Day scheduled for approximately 21 January 2026, where the Project Manager Self-Propelled Howitzer Systems (PM SPHS) will discuss organizational vision and seek industry feedback on three key topics: intellectual property, onshoring to the Continental United States (CONUS), and prototype delivery for Safety Release testing. The government plans to award a single contract through a competitive technical evaluation, with interested parties required to submit written questions by 16 January 2026 and electronic responses in searchable Microsoft Word format by the same date.
