Rock Island Arsenal Joint Manufacturing and Technology Center

Rock Island Arsenal Joint Manufacturing and Technology Center is a U.S. Army government manufacturing center at Rock Island Arsenal in Illinois. It supports the Army and Department of Defense through conventional and advanced manufacturing, foundry work, armor fabrication, mobile maintenance systems, and sustainment of artillery systems including the M119 105 mm howitzer.

RIA-JMTC is part of the Army's organic industrial base rather than a private defense contractor. Its public record ties the center to Rock Island Arsenal's long-running ordnance manufacturing role, while modern Army reporting describes it as a vertically integrated manufacturer that can take raw material through finished military components under one roof.

Army sources identify Rock Island Arsenal-Joint Manufacturing and Technology Center as the original equipment manufacturer for the M119 and M198 howitzer families, and as a continuing source of parts, upgrades, and production support. Broader Army sources also document its foundry, add-on armor, mobile maintenance, and advanced manufacturing missions.
