U.S. Re-onshores TNT Production as Demand Rises; Europe Locks In Supplies with New Deals

November 14, 2025 – The United States is moving to re-onshore production of trinitrotoluene (TNT), the high explosive used in artillery shells, aerial bombs, and infantry grenades, amid intensifying demand for munitions. The push was spotlighted by CNBC, which explored the growing need for TNT and featured analysis from GlobalData aerospace and defence analyst James Marques.

U.S. moves to rebuild TNT base

American efforts to restore and expand domestic TNT production are gathering pace as the munitions supply chain adapts to sustained demand. TNT remains a prime high explosive in munitions manufacturing, central to replenishing national stockpiles and meeting ongoing production schedules for artillery and air-delivered ordnance.

Earlier coverage detailed investment decisions targeting TNT capacity across the U.S. and Europe. In the U.S., projects include Repkon’s future factory in Kentucky, an example of the new industrial build-out aimed at bolstering explosive supply and shortening logistics chains.

Industry analysis on CNBC

CNBC examined the U.S. TNT market pressures and supply response, featuring insight from GlobalData’s James Marques. The segment assessed demand trajectories, production bottlenecks, and the strategic significance of re-establishing domestic explosive manufacturing.

Europe secures explosive supplies

European defence customers are also acting to shore up access to critical propellant and explosive materiel. The UK-based Astor Defence has focused on TNT availability through multi-year contracts with leading original equipment manufacturers (OEMs):

• In 2024, Astor Defence signed a deal with Norwegian-Finnish defence OEM Nammo for “thousands of tons” of TNT.
• In 2025, Astor Defence signed a TNT agreement with UK defence prime BAE Systems to support “large-scale” munitions programmes.
• Astor Defence had previously said it had “spare capacity” for TNT supply through 2025.

Why TNT capacity matters

TNT’s role at the core of munitions manufacturing makes it a strategic input for both U.S. and European defence industrial bases. Ensuring reliable access supports production of artillery shells, aerial bombs, and grenades, while reducing exposure to supply chain disruptions.

U.S. re-onshoring initiatives aim to increase resilience, shorten supply lines, and expand throughput. In parallel, European contracts are designed to lock in volumes and underpin long-term munitions programmes, reflecting a broad-based effort across NATO-aligned nations to stabilize critical explosive inputs.

Key developments at a glance

• U.S. re-onshoring TNT production to meet sustained munitions demand.
• CNBC coverage highlights market pressures and features analysis by GlobalData’s James Marques.
• Repkon advancing a future factory in Kentucky to support U.S. explosive capacity.
• Astor Defence-Nammo (2024) TNT deal for “thousands of tons”.
• Astor Defence-BAE Systems (2025) TNT agreement supporting “large-scale” programmes.
• Astor Defence previously noted “spare capacity” for TNT supply through 2025.

Conclusion

The latest moves underscore a transatlantic effort to secure TNT supply for current and future munitions output. With the U.S. expanding domestic production and European manufacturers locking in contracts, industry watchers will look for capacity ramp-ups, new facility milestones, and multi-year sourcing agreements to determine how quickly explosive availability aligns with production goals.
