The UK Royal Navy's amphibious assault ship HMS Ocean is set to participate in Nato's Exercise Trident Juncture.
Exercise Trident Juncture, is claimed to be the largest Nato exercise since 2002.
Sailing from Devonport, the Royal Navy warship includes 45 Commando, Merlin, Apache, and Chinook helicopters from the Fleet Air Arm, Army Air Corps and RAF.
The exercise is expected to offer the Royal Navy with an opportunity to train with and work alongside navies from Nato allies and partner nations in the region.
HMS Ocean will join with a task group of approximately 70 warships from across Nato countries.
Exercise Trident Juncture will also enable the Royal Navy's Maritime Battle Staff to command the naval element of the Nato Response Force in 2016.
Nato recently conducted its submarine warfare exercise Dynamic Manta 2015 (DYMA 15) off the Sicilian coast.
The exercise involved ships, submarines, and aircraft and personnel from nine Allied nations.
DYMA 15 aimed to offer participants complex and challenging warfare training to improve interoperability and proficiency in anti-submarine and anti-surface warfare.
The training programmes included capability testing of personnel, systems and sensors, from basic serials to more advanced exercises.
In addition, Royal Navy's Albion-class assault ship HMS Bulwark recently practised amphibious landings with the support of helicopters from HMS Ocean, as well as elements of the Royal Marines.
The elements participated in the training that forms part of the Joint Expeditionary Force (Maritime), which is the UK's very high-readiness task force.
