About Arcane Thunder

Arcane Thunder 26 highlights the U.S. Army’s continued refining multi-domain operations and demonstrates how U.S. forces operate alongside NATO Allies and partners to deter adversaries across Europe. The exercise validates the employment and qualification of Multi-Domain Company Teams (MDCTs), integrating cyber, space, electronic warfare, and conventional capabilities to create synchronized multi-domain effects.

Arcane Thunder 26 is a geographically distributed exercise conducted across the United States, Germany, and Poland that links sensors and shooters across domains to enable rapid decision-making and precision effects. The exercise supports NATO regional defense plans and reinforces the Eastern Flank Deterrence Initiative (EFDI), demonstrating the Alliance’s ability to deter aggression and defend the Euro-Atlantic region.

Through Arcane Thunder 26, U.S. and Allied forces rehearse the integration of kinetic and non-kinetic capabilities to penetrate and disintegrate adversary anti-access/area denial (A2/AD) systems, enabling freedom of maneuver for the joint force and strengthening NATO’s deterrence posture.

Did you know a single river is responsible for moving 35% of all U.S. waterborne commerce? The Ohio River is the 981-mile backbone of our nation's economy, transporting over 270 million tons of cargo annually and supporting more than half a million American jobs. This massive economic engine depends entirely on a network of locks and dams, many of which are aging . In this video, discover why this inland waterway is vital to America’s economy and see how the U.S. Army Corps of Engineers is working to modernize this critical infrastructure. We are guided by a clear principle: Build Infrastructure, Not Paperwork. Our mission is to cut delays and deliver projects faster to strengthen our national economy and supply chains for generations to come .
