Trump Says Proposed D.C. Arch Will Double as Military Complex
President Trump said on Sept. 20, 2026, that his planned 250-foot triumphal arch in Washington, D.C., would double as a "top grade Military Complex."
That added a military use to a project the administration had described as a commemorative and tourist structure. Trump said he had agreed to a military request to convert the proposed arch near Arlington into a military complex, according to Reuters.
In a Truth Social post, Trump said the structure will "house, store, and have the rapid ability to use large numbers of drones, plus Snipers, on both the roof and plaza areas." He said the arch would also store ammunition. Reuters reported his description as storing sniper ammunition.
Trump first unveiled the arch proposal in October 2025, according to NPR. He first told journalists the arch was being built to honor "me." The administration later described it as a tribute to America's 250th anniversary and a tourist attraction.
National Park Service drawings described the arch with an observation deck looking toward Arlington National Cemetery and the National Mall, possibly with a cafe and gift shop. The Commission of Fine Arts, the federal board that reviews design in central Washington, approved the arch designs in May 2026.
In September 2026, Interior Secretary Doug Burgum said on social media that digging would soon start at the "Great Triumphal Arch and Military Observation Deck." That announcement drew pushback and a judge's intervention reported Sept. 4, 2026. A judge ordered 48 hours' notice tied to the project in early September 2026.
The project still needs final approval from the National Capital Planning Commission, which signs off on federal construction in the capital area. That approval cannot happen until required historic preservation reviews are complete.
The National Park Service asked preservation groups in September 2026 to comment by Monday on its draft Memorandum of Agreement, the formal deal needed to advance the arch. Charles Birnbaum, CEO and founding president of the Cultural Landscape Foundation, told the Park Service and NPR that "we view this MOA as DOA [dead on arrival]."
The broader context here is procedural risk. A design cleared by the Commission of Fine Arts still must pass the Planning Commission, and the Planning Commission cannot act until the preservation review ends with a signed agreement. Adding housing, storage and operational use of drones, snipers and ammunition changes the stated purpose, even as comments on that agreement were due. That leaves the administration to match a new operational claim with a commemorative project file already in litigation and under a notice order.
