HMS Duncan carried out anti-submarine and air defence training.
The Type 45 Destroyer spent two weeks off the coast of Italy, joining eight other countries and 57 ships, helicopters and aircraft in Exercise Mare Aperto, say the Royal Navy in a release.
“The Royal Navy ship conducted six anti-submarine and 11 air defence exercises in seven days before the participating units divided into opposing forces to test their abilities.
As one of the most capable air defence assets within the NATO group, Duncan was tasked with providing air and surface defences as the exercise moved through the Messina Straits which divide Sicily and mainland Italy.”
In the scenario, Italy and Sicily were allies while Sardinia played a hostile nation.
To retake control of the region, a major amphibious taskforce was deployed to Sardinia with the Italian ship San Guisto and Spanish ship Galicia landing two battalions of marines ashore.
