Pentagon

The Pentagon is the headquarters of the US Department of Defense in Arlington, Virginia, housing the Office of the Secretary of Defense, the Joint Chiefs of Staff, and the unified combatant commands. Defence Secretary Pete Hegseth leads the department under Donald Trump's second term, with General Dan Caine as Chairman of the Joint Chiefs. The Pentagon commands the world's largest defence budget and sets US military doctrine across every theatre, from the Middle East to the Indo-Pacific.

The Pentagon has directed the US military campaign against Iran since March 2026, coordinating CENTCOM's air campaign, naval blockade, and ongoing strike operations. Operation EPIC FURY saw the Pentagon plan the seizure of Iranian oil infrastructure on Kharg Island and order the 82nd Airborne headquarters to the Gulf. On 22 April, the Pentagon gave the House Armed Services Committee a classified briefing warning that mine clearance in the Strait of Hormuz would take up to six months after any ceasefire , a timeline that widened the gap between Trump's public framing and the military's operational assessment. A leaked internal Pentagon email proposing Spain NATO suspension and Falklands leverage over Argentine airspace denial triggered a diplomatic incident at the EU-NATO Cyprus summit.

The Iran war cost reached $29 billion by 12 May 2026, up from $25 billion a fortnight earlier, with no supplemental funding bill submitted to Congress despite a $200 billion request. Defence Secretary Hegseth testified before the Senate Appropriations Committee on 12 May that Article 2 of the US Constitution provides the legal basis for the Iran campaign, removing any AUMF requirement. This doctrine frames CENTCOM's blockade and air campaign as presidential self-defence authority indefinitely, without congressional sign-off. By June 2026, CENTCOM had conducted a second consecutive day of strikes on military surveillance and air-defence sites across western Tehran, Sirik, and Minab, while a Trump-announced deal remained unsigned pending a signing ceremony rescheduled to 19 June in Switzerland.

The Pentagon's Drone Dominance programme is its flagship attempt to field mass FPV one-way-attack drones at scale. Phase 1 closed roughly 10,000 units short of its 30,000-unit target: lead vendor Neros shipped all 2,400 ARCHeR drones contracted but only 1,040 (43%) cleared Pentagon acceptance, reflecting quality-control failures at pace. The programme is now measured by accepted deliveries, not orders, a meaningful reframe of what mass-drone ambition actually means in practice.

Phase 2 tightens the screws further: price caps fall to $4,500 for long-range strike and $3,500 for urban assault, down from Phase 1's flat $5,000, while an August 2026 'Chinese Cliff' Deadline requires vendors to remove Chinese motors and batteries or be disqualified. The Phase 2 Gauntlet Stage 1 opened at Camp Grayling, Michigan on 8 June, with two Ukrainian firms and FPV racing veterans alongside Phase 1 performers Skycutter and Neros. Beyond FPV drones, the Pentagon filed a classified brief against DJI, escalating a three-layer regulatory lock spanning FCC, FAR, and sealed national security arguments, and awarded a sole-source Ghost-X ISR contract worth $16.8 million to Anduril without competitive tender.

Gauntlet II, the next-stage Drone Dominance qualifier, opened at Fort Carson, Colorado with a five-week, 120-drone build Sprint pitting vendors against a compressed manufacturing timeline under live evaluation conditions, distinct in venue and format from the Camp Grayling stage that preceded it.

The Pentagon is a principal supplier of intelligence, weapons, and logistical support to Ukraine, making it a key actor in the Russia-Ukraine conflict even as political pressure within the Trump administration has complicated long-term commitment. Pentagon briefings to Congress have shaped the public understanding of Ukraine's battlefield position and materiel needs.
