US deploys nuclear submarine to warn Iran
The move came shortly after US President Donald Trump reportedly rejected Iran’s latest ceasefire proposal and criticized Tehran’s response as “totally unacceptable.”
The United States has deployed the nuclear-powered ballistic missile submarine USS Alaska to the Strait of Gibraltar in a rare show of strategic force amid escalating tensions with Iran over the Strait of Hormuz and Tehran’s nuclear program.
According to a report by Army Recognition, the Ohio-class submarine arrived at Gibraltar’s South Mole naval facility under heavy security escort, accompanied by Gibraltar Squadron patrol vessels, Gibraltar Defence Police units, and Royal Marines detachments.
The highly visible deployment of an operational ballistic missile submarine — assets typically kept hidden during deterrence missions — has been widely interpreted by military analysts as a direct warning to Iran.
The USS Alaska, part of the sea-based component of the US nuclear triad, is capable of carrying up to 20 Trident II D5 ballistic missiles. Its position near the strategic maritime corridor linking the Atlantic Ocean and Mediterranean Sea provides Washington with rapid access toward the Middle East during a period of heightened regional instability.

Rare public appearance
Military experts described the submarine’s docking in Gibraltar as an unusually public form of nuclear signaling, noting that Ohio-class submarines rarely make visible port calls during active deterrence patrols.
British authorities imposed a 200-meter exclusion zone around the submarine following its arrival, while additional Royal Marines personnel were reportedly deployed to reinforce security.
The report noted that this marks only the third publicly observed visit by a US Ohio-class ballistic missile submarine to Gibraltar in approximately 25 years.
Commissioned in 1986, USS Alaska underwent major modernization upgrades between 2006 and 2009, including advanced combat systems and Trident II missile integration. Powered by a nuclear propulsion system, the submarine can remain submerged for strategic patrols lasting up to 90 days.
Hormuz fears intensify
The deployment comes as concerns grow over the security of the Strait of Hormuz, one of the world’s most important energy shipping routes.
Amin Nasser, chief executive of Saudi Aramco, warned that any prolonged disruption in the strait could trigger “the largest energy supply shock in history.”
According to Nasser, global markets have already lost an estimated one billion barrels of oil supply, while a continued closure of Hormuz could remove an additional 100 million barrels from the market each week.
At the same time, Iranian naval commander Shahram Irani confirmed the deployment of Iran’s domestically produced Ghadir-class mini submarines in the Strait of Hormuz during naval drills conducted on May 10.
The submarines, designed for shallow-water and asymmetric warfare operations, are reportedly capable of launching ambush attacks using torpedoes and missiles while remaining concealed near coastal terrain.
Escalating standoff
The latest military movements follow the collapse of negotiations between Washington and Tehran over uranium enrichment, sanctions relief, and maritime access through Hormuz.
Iran has continued to reject demands to scale back parts of its nuclear program, while the United States has maintained pressure for tighter enrichment restrictions and guarantees of unrestricted commercial shipping through the strait.
Analysts cited in the report said the deployment of USS Alaska appears intended as a calibrated strategic signal aimed at reinforcing US deterrence without immediately escalating toward direct conventional conflict.
Regional security concerns have also increased following reports of drone-related incidents across Kuwait, Qatar, the United Arab Emirates, and northern Iraq.
Iran has increasingly relied on smaller submarines and fast attack craft after several of its larger naval vessels were reportedly damaged or destroyed during recent confrontations involving the United States and Israel.
