The United States has stepped up its military positions around Iran, deploying an aircraft carrier strike group, fighter jets, and missile defence systems to West Asia, amid heightened tensions following violent crackdowns on nationwide protests inside Iran.
US officials said the strike group led by the USS Abraham Lincoln, accompanied by guided-missile destroyers and an attack submarine, is expected to enter the Arabian Sea or the Persian Gulf region in the coming days. The deployment marks a sharp escalation in pressure on Tehran, with Washington citing concerns over civilian deaths during protests triggered by Iran’s worsening economic crisis.
The carrier group was last publicly tracked in the Indian Ocean after being redirected from the South China Sea. Its current location is no longer visible on open-source maritime tracking systems.
Fighter jets and missile defences moved to region
Alongside naval deployments, F-15E Strike Eagle fighter jets have already arrived at an undisclosed base in West Asia. US Central Command shared visuals of one such aircraft landing earlier this week. The jets are part of a broader redeployment that includes KC-135 aerial refuelling aircraft, allowing combat planes to extend their operational range.
Additional missile defence systems, including THAAD and Patriot batteries, have also been positioned across the region, particularly in US-allied countries such as Israel and Qatar, according to media reports.
Protests and human rights concerns
The military build-up comes against the backdrop of prolonged unrest in Iran, where demonstrations over economic hardship escalated into nationwide protests late last year. Iranian state-linked outlets have reported more than 3,000 deaths, including civilians and security personnel, while rights groups estimate the toll could be significantly higher.
US President Donald Trump has repeatedly warned of military consequences, claiming American pressure forced Iran to halt planned executions of protesters. He reiterated this claim earlier this week, stating that hundreds of executions were cancelled following US threats. However, his remarks have since softened, reflecting a pattern of combining military pressure with diplomatic signalling.
Iranian leaders, meanwhile, have accused the US and Israel of instigating unrest as retaliation for earlier military strikes on nuclear facilities. Tehran has warned it is prepared to respond to any further aggression.
Nuclear concerns resurface
Adding to the uncertainty is the unresolved issue of Iran’s enriched uranium stockpile. Around 400 kilograms of enriched material — enough for multiple nuclear weapons — remains unaccounted for following US strikes on Iranian nuclear sites in June 2025.
Iran is expected to report to the International Atomic Energy Agency on the status of nuclear material at affected facilities, including the Fordow site. However, inspections have not taken place for several months, despite agency guidelines recommending regular monitoring.
Trump has stated that the US would act if Iran resumes its nuclear programme, reinforcing concerns that military options remain on the table.
What action could look like
Military observers say any US response is likely to begin with limited, targeted strikes aimed at deterrence rather than full-scale conflict. Such actions typically focus on missile launch sites, drone infrastructure, and command networks, often paired with diplomatic channels to prevent escalation.
While a direct strike on nuclear facilities cannot be ruled out, analysts caution that retaliation from Iran could draw the US and its allies into a wider regional conflict.
Iran’s response options
Iran is expected to avoid direct confrontation, instead relying on calibrated responses through aligned regional groups, cyber operations, or maritime pressure. Past actions suggest Tehran prefers visible but limited retaliation to signal resolve without triggering all-out war.
One of Iran’s most significant leverage points remains the Strait of Hormuz, a critical route for global oil supplies. Even limited disruption in the area could raise energy prices and intensify international pressure on Washington.
Israel on high alert
Israel has placed its air defence systems on alert amid the unfolding situation. If the US proceeds with military action, Israel is likely to become a secondary target due to its close alliance with Washington.
While Israel possesses advanced multi-layered air defence capabilities, joining a US-led strike is considered unlikely, as it remains engaged on other fronts and faces the risk of a broader regional escalation.
