Satellite imagery tracks US military build-up near Iran

The United States has significantly increased its military presence in the Middle East amid heightened tensions with Iran, satellite imagery and defence analysts tracking warships and aircraft movements suggest, even as officials from both nations prepare for diplomatic talks.

Satellite tracking by independent observers indicates that a carrier strike group centred on the USS Abraham Lincoln and several destroyers is operating in waters near Iran. The group is led by the nuclear-powered aircraft carrier and includes F-35 fighters and other aircraft, and was recently seen in the Arabian Sea off the coast of Oman. Another carrier, the USS Gerald R. Ford, is reportedly en route to the region and expected to arrive within weeks, says the BBC.

The United States has also positioned destroyers in the Red Sea and the eastern Mediterranean, while military airfields in Jordan have seen an increase in fighter, cargo, refuelling and communications aircraft.

Analysts tracking the deployments said the current build-up "has more depth and sustainability" than earlier US operations such as the seizure of Venezuelan leader Nicolás Maduro or last year's strikes on Iranian nuclear sites. They said the combination of naval and air assets could support a high operational tempo if required.

In Washington, defence officials have framed the deployments as a deterrent. They have highlighted that a stronger presence is meant to dissuade potential hostile actions and to protect US forces, bases and regional partners.

The build-up has unfolded alongside preparations for diplomatic discussions in Switzerland aimed at addressing Iran's nuclear programme and economic sanctions. A US official said both sides are seeking to manage multiple tracks — military readiness and diplomatic engagement — amid broader concerns over Iran's missile programme and regional influence.

In Tehran, the Islamic Revolutionary Guard Corps has conducted maritime drills in the Strait of Hormuz, a strategic waterway through which a significant share of the world's oil supplies transit. The exercises included missile launches and inspections of vessels near Kharg Island, Iran's primary oil export terminal.

Iranian state media cited the drills as a response to what it termed a "show of military prowess" by the United States. Iran has maintained that it seeks to resist pressure and defend its territory.

The scheduled talks in Switzerland reflect sustained diplomatic engagement even as both sides underscore their security concerns. Iran has repeatedly said it seeks relief from economic sanctions, while US officials have said broader issues including regional stability and arms programmes will be discussed.

Reuters could not independently verify all details of the military movements, and US defence officials have declined to comment on specific force posture.
