US military to send Marines and more warships to Middle East, reports say
The US is deploying thousands of Marines and additional warships to the Middle East to reinforce security and deter further Iranian attacks on shipping and regional targets.

The United States is moving additional Marines and warships into the Middle East amid the intensifying conflict with Iran, military officials and multiple media reports say. The deployment reflects growing concern in Washington over Iranian attacks on strategic waterways and the possibility of further escalation in the region.
According to US defence sources cited by ABC News and other outlets, a Marine expeditionary unit (MEU) carrying around 2,200 – 2,500 Marines has been ordered to deploy to the Middle East aboard a group of amphibious warships. The movement comes as Iranian missile and drone strikes disrupt shipping and threaten key global oil routes.
Troop and Naval Reinforcements Underway
The amphibious ready group — typically composed of several warships and a Marine expeditionary unit — will operate alongside the existing US naval presence in the region. One of the ships, the USS Tripoli, is said to be sailing from its home base in Japan toward the Middle East with its embarked Marine contingent.
The deployment order was approved by US Defense Secretary Pete Hegseth following a request from US Central Command (CENTCOM), the military command responsible for operations in the Middle East. Officials told reporters that the forces could be used for a range of missions, from force protection and rapid response to potential evacuations or defence operations, depending on how the conflict unfolds
Though the exact composition of the warship group has not been fully disclosed, Pentagon movements suggest it could include three amphibious vessels — typically transport ships capable of carrying Marines, equipment, and aircraft — forming a mobile crisis‑response force.
Why Reinforcements Are Being Sent
The deployment comes as Iran’s attacks on shipping in the Strait of Hormuz, a crucial chokepoint for global energy supplies, have effectively closed parts of the waterway, contributing to higher oil prices and international concern. Tehran’s missile and drone operations have also targeted vessels and military assets belonging to regional states and allied forces.
US officials have described the reinforcement as a show of deterrence and security assurance, aimed at protecting American personnel and interests in a highly volatile environment. The Marines’ presence, along with additional warships, also provides Washington with flexible options in the event of further escalation or threats against US facilities and allies.
Analysts say such deployments — while not necessarily signalling an imminent ground invasion — underscore the depth of US commitment to counter Iranian military pressure and secure key maritime routes. The amphibious ready group’s mobility and organic aviation capabilities mean it can support a wide range of missions without requiring fixed bases ashore.
Regional and International Context
These reports of reinforcements align with broader developments in the Middle East military landscape. The US has maintained an expanded naval presence since late 2025, with aircraft carrier strike groups, destroyers and supporting vessels operating in the Persian Gulf, Arabian Sea and Red Sea in response to threats from Iran and allied militias.
President Donald Trump’s administration has also authorised significant air and naval strikes against Iranian targets, describing them as necessary to counter Tehran’s interference with commercial shipping and attacks on regional partners. Meanwhile, Iran has threatened further measures against oil infrastructure linked to the US and its allies if its access to strategic waterways continues to be contested.
Potential Implications
Sending Marines and warships to the Middle East during an active conflict carries operational and political implications. Domestically, such moves are likely to draw scrutiny from Congress and the public amid ongoing debate over US military involvement abroad. Internationally, the bolstered presence highlights how Washington is positioning itself not just as a combatant but as a security guarantor for global energy routes and allied defence commitments.
Despite the lack of an official Pentagon announcement, the deployment reported by US media reflects the reality of an expanding American military footprint as tensions with Iran show no sign of abating. As the situation continues to evolve, further shifts in US force posture and strategic objectives are likely to be watched closely by allies and adversaries alike.
