The Portsmouth-based destroyer joined the USS John C Stennis and USS Abraham Lincoln carrier battle groups, honing skills needed to work with Britain’s new Queen Elizabeth-class flagships.
The Stennis is making her way home to Norfolk, Virginia, after operations in the Middle East while USS Abraham Lincoln is in the early stages of a deployment which will take her to the Gulf and Pacific before arriving at her new home of San Diego.
Both nuclear-powered warships, displacing 100,000 tonnes each, are home to upwards of 6,000 sailors, marines and aviators, some 60 fast-jets – mostly F/A-18 Hornet strike fighters – plus intelligence gathering Hawkeyes and around 20 helicopters.
They can launch more than 120 sorties a day during intensive operations – including catapulting more than 20 F/A-18s skywards one after another in rapid succession.
Duncan is one of six Type 45 destroyers built to both defend a task group from air attack as well as to guide jet fighters and bombers on to targets.
Since then she has broken away from the French to join a NATO task force patrolling the Mediterranean, promoting the work of the alliance and conducting combined training to ensure the group is ready for any eventuality.
