The Army's planned 155mm artillery loading plant in southeast Iowa now costs about $106 million more than it did 15 months ago. That raises the price of one of the service's efforts to rebuild artillery shell output, on a contract the Army awarded without competition. In its Nov. 6, 2026 contract announcement, the Defense Department said MSM Group North America Inc. of St. Petersburg, Florida, received a $105,774,000 modification (P00004) to contract W519TC-25-C-0032 for "the design, build, and commission of a modern 155mm load, assemble, and pack facility at the Iowa Army Ammunition Plant." The Pentagon said the change "brings the total cumulative face value of the contract to $740,974,000."

Work will take place in Middletown, Iowa, with an estimated completion date of Aug. 10, 2029. The Army obligated $42,887,000 in fiscal 2025 Army ammunition procurement funds when it signed the modification. Army Contracting Command, Rock Island Arsenal, Illinois, is the contracting activity.

How the Future Artillery Complex Went From $635M to $741M

The Army first announced the contract in August 2025. According to the Army release, the Joint Program Executive Office Armaments & Ammunition's Project Lead Joint Services and Army Contracting Command-Rock Island awarded "a $635M fixed-price-with-economic-price-adjustment contract to MSM Group North America to design, build, and commission the Future Artillery Complex, or FAC, at the Iowa Army Ammunition Plant."

The Army did not compete the work. The release said the contract "is being executed as a sole source undefinitized contract action" under 10 U.S.C. 3204(a)(7) and Subsection 1244(a)(2) of the James M. Inhofe National Defense Authorization Act for Fiscal Year 2023. HigherGov's record of the award notice lists a ceiling of $635,200,000.

Those figures add up exactly. The $740,974,000 total minus the $105,774,000 modification leaves $635,200,000, the original ceiling. The new money therefore increases the contract's face value by roughly 17%. The announcement does not say what the added $105.8 million pays for. An undefinitized contract action lets work start before the government and contractor settle final terms and price, and contract values often move once those terms are definitized. The DoD notice does not use the word "definitization," though, so readers should not assume that explains this modification.

Early press coverage also gave different figures. Defense Daily reported in August 2025 that the Army had awarded MSM North America "a $632.5 million contract." The Army put it at $635 million, and the award notice ceiling was $635.2 million. All of those numbers fall below today's $741 million.

What the Iowa Plant Is Supposed to Produce

The FAC is a load, assemble and pack (LAP) line. That is the stage where empty 155mm projectile bodies are filled with explosive, fitted with components and packed for shipment. According to Defense Daily, the facility "will be capable of loading 36,000 155mm artillery rounds per month." The outlet reported that MSM North America, which it identified as a subsidiary of Czechoslovak Group, "said construction of the Future Artillery Complex (FAC) is expected to be completed within 40 months and that the new load, assemble and pack facility will begin operating in September 2029."

The new DoD completion estimate of Aug. 10, 2029 is close to that timeline. It also means the plant will not add LAP capacity for nearly three more years.

The Army's 2025 release laid out the design goals. It said the plant "will feature 21st century manufacturing technology that will provide the Army with a scalable, flexible and affordable explosive load, assemble and pack facility," and that it will blend robotics and automation with integrated system control and data acquisition systems. The release said the line is meant to transition "seamlessly between products with minimal downtime" and to operate economically "at either peak capacity or reduced Minimum Sustaining Rate."

Why the Army Is Paying to Rebuild 155mm Capacity

Army leaders presented the FAC as part of a broader modernization push. "The FAC represents much-needed new technology investments to modernize the Arsenal of Democracy in order to meet the evolving demands of the warfighter in 2025 and beyond," said Maj. Gen. John T. Reim, Joint Program Executive Officer Armaments & Ammunition and commanding general at Picatinny Arsenal, in the August 2025 release.

Reim also tied the project to the money Congress has put into the base: "When the Army realized the need to modernize our production capabilities, Congress allocated $5B to add capacity and bring the defense industrial base into the 21st century." The release said most of the nation's munitions plants "were built during World War II and are operating much the same way they did 80 years ago."

Reim made the same production argument in a second statement: "It is not lost on us that victory on the battlefield starts in our production facilities. The FAC will enable munitions production at speed and scale thereby increasing Army readiness and Warfighter lethality."

What It Means for Contractors

The modification sends several signals to firms that work in the munitions industrial base and on government-owned plant construction.

  • Watch for further price movement on sole-source facility builds. This contract grew by about 17% within 15 months, before the plant is built. The sources do not say why, but subcontractors pricing work under the FAC should read their flow-down terms on economic price adjustment closely and expect that the contract value could change again.
  • Funding came in a piece. Only $42.9 million of the $105.8 million modification was obligated when it was signed. The notice does not explain the remainder, so subcontractors should confirm with the prime how and when additional money will be obligated before committing to release schedules.
  • Automation suppliers may find an opening. The Army's emphasis on robotics, integrated control and data acquisition systems, and fast product changeover suggests potential demand for industrial automation, controls integration and explosive-safe handling equipment as the plant is built through 2029.
  • Foreign-parented primes are part of the picture. The Army chose MSM Group North America, which Defense Daily identified as a subsidiary of Czechoslovak Group, as sole-source builder for a government plant. Domestic suppliers may want to consider teaming with, rather than competing against, foreign-parented primes on similar work.
  • Track the operating date, not just the dollars. Defense Daily's reported September 2029 start date and the DoD's Aug. 10, 2029 completion estimate mark the window when follow-on work for operations, sustainment and component supply at Middletown might begin.

Rock Island remains the contracting office to watch for the next action on W519TC-25-C-0032.
