The gathering in Carlisle, Pennsylvania, is organized by Republican Sen. David McCormick. It has also featured Defense Secretary Pete Hegseth; Gen. Dan Caine, chairman of the Joint Chiefs of Staff; Army Secretary Dan Driscoll; CIA Director John Ratcliffe; and Mike Waltz, U.S. ambassador to the United Nations.

Trump has been a frequent visitor to the critical swing state of Pennsylvania, including last month, when he went to a Mack Trucks facility in Macungie, outside Allentown — hoping to boost Republican Rep. Ryan Mackenzie’s reelection chances.

The White House said the summit is bringing together key leaders in defense and some of the largest global investors to spotlight the importance of national security and identify investment opportunities.

Summit attendees include JPMorgan’s Jamie Dimon, Blackstone President Jon Gray, Lockheed Martin CEO Jim Taiclet, General Dynamics CEO Phebe Novakovic, Boeing CEO Kelly Ortberg, SpaceX director Antonio Gracias, and Shyam Sankar, chief technology officer of analytics and artificial intelligence firm Palantir, McCormick’s office said.

Trump spoke at a similar gathering organized by McCormick last year in Pittsburgh that sought to make the city a hot spot for advancement in energy technology and robotics. Then, the senator announced $90 billion in pledged investments in those sectors across Pennsylvania.

This year’s summit began on Tuesday. Before Trump’s arrival, multi-analytics threat detection leader ZeroEyes, which is based in Conshohocken, outside Philadelphia, announced a planned $10 million investment in artificial intelligence and machine learning research and development.

Pittsburgh-based Gecko Robotics also says it plans to open a new 10,000-square-foot (930-square-meter) manufacturing facility designed to boost integration of robotics into defense manufacturing processes and better expand the nation’s defense industrial base.

An analysis released in May found that U.S. military contractors will need at least three years to replenish stockpiles of Tomahawks — used to strike targets deep inside enemy territory — as well as Patriots and THAAD interceptors, which defend against incoming missiles and drones.

China has a stated goal of ensuring its military is capable of taking Taiwan by force if necessary by 2027, which experts see as more aspirational than a hard deadline. But Chinese President Xi Jinping warned during Trump’s recent visit to Beijing that if Washington mishandles its relations with the self-governing island, the U.S. and China could end up clashing or even find themselves in open conflict.

Trump has sought to correct the shortfall by seeking a historic $1.5 trillion defense budget proposal for 2027. But a package authorizing such spending levels is stalled in Congress, and, even if it eventually moves forward, loads of additional time will still be required to expand production capabilities to accommodate such weapons systems.

Jake Loosararian, co-founder and CEO of Gecko Robotics, said U.S. defense companies have “got to supercharge supply chains” to reduce how long it takes for new technology to be ready for widespread production.

“President Trump uniquely understands the importance of pragmatic impact today,” Loosararian said. “He also understands big, beautiful things for tomorrow.”
