Quick Summary

The USS Theodore Roosevelt left San Diego on Sunday with additional military units, joining two other US aircraft carriers already operating against Iran. This deployment increases the potential US military presence in the Middle East to more than 60,000 personnel and marks the largest buildup since the 2003 Iraq invasion. The Theodore Roosevelt is accompanied by several support ships and aircraft, including F-35C fighter jets and electronic warfare planes. Additionally, an amphibious ready group with over 2,000 Marines is also sailing from San Diego to reinforce the region's US military presence expected by late November.

Story summary

In October, Al Jazeera reported that a 2.5-million-barrel supertanker was hit by an unknown projectile while passing through the Strait of Hormuz, causing a fire but no casualties. Meanwhile, the USS Theodore Roosevelt carrier strike group and the USS Makin Island amphibious readiness group left San Diego, carrying over 7,000 sailors and 2,000 Marines respectively, bound for the Middle East to bolster military presence around Iran. By November, three aircraft carriers and two landing groups are expected to be positioned in the region, adding to the existing roughly 50,000 U.S. troops already there. The new deployment includes additional F-35 fighter jets and underscores President Trump’s war strategy against Iran ahead of November US midterm elections, amid growing tensions and diplomatic stalemate.
