The British Royal Navy’s Type 45 Destroyer HMS Duncan carried out anti-submarine and air defense training in an exercise
with eight other countries and 57 ships, helicopters and aircraft. The HMS Duncan is the sixth Type 45 Destroyer and was deployed in 2018 as the Flagship of NATO Task Group SNMG2, returning in July. The Type 45 Destroyers
built for the Royal Navy are primarily designed for anti-aircraft and anti-missile warfare. For the exercise, dubbed Mare Aperto, the ship spent two weeks off the coast of Italy, where it provided air and surface defenses as the exercise moved through the Messina Straits which divide Sicily and mainland Italy. The exercise is focused on training and testing the abilities of the Commanders and Staff of the Naval Squadron, in conducting operations in areas of international crisis. Through the reproduction of a scenario characterized by a multidimensional threat and with increasing difficulty, ships and crews practice the main activities of fighting on the sea and from the sea such as anti-aircraft, anti-submarine and anti-ship activities, fighting illicit trafficking, crisis management in environments with conventional and asymmetric threat.
To replace them, the Royal Navy planned to induct 12 Type 45 Daring Class destroyers. The Daring class would be built to deal with a new age of threats. Saturation attacks with supersonic ship-killing missiles, that fly from the ship’s radar horizon to ship impact in under 45 seconds. The reality of future threats from ballistic missiles, and WMD proliferation. Plus a proliferation of possible threats involving smaller, hard to detect enemies like UAVs. Overall, the Type 45s promise to be one of the world’s most capable air defense ships – but design choices have left the cost-to-value ratio uncertain, and limited the Type 45s in other key roles. A reduced 6-ship program moved forward.
