845 NAS

845 Naval Air Squadron

845 Naval Air Squadron formally took over the Merlin Mk3 from RAF’s 28 Squadron as the air force’s last Merlin formation passed into history.

Add to favourites

845 stood down as a Sea King formation back in May, handing over the last of its veteran helicopters to 848 NAS who’ll see them out of service over the next eight months. 

In the meantime, the normally-Yeovilton-based 845 NAS are settling down in Oxfordshire until summer of 2016 as air and ground crews get to grips with an aircraft which is at least one generation ahead of the helicopter it replaces. 

And as they do, 28 will be turning into a Puma and Chinook training squadron preparing RAF fliers for front-line duties.

Students are off to a Flying Start the inspirational student engineering challenge held at Royal Naval Air Station.

    The UK is provided military support in order to supply humanitarian relief to the Caribbean Islands left devastated by Hurricane Irma in September 2017.

Ready to fight

When diplomacy fails, the UK has to be ready to protect its interests and its allies. What’s more, as a member of NATO and the UN, the UK also acts to support the enforcement of UN resolutions and come to the aid of our allies. This is where the Royal Marines come in: we train to go where we’re needed – by sea, land or air – and deploy our forces with the aim of restoring peace.

International partnerships

As the fifth largest economy in the world, the UK has responsibilities towards its allies and partners. But Britain also has global ambitions – namely to protect the seaways underpinning the country’s prosperity. The Royal Navy plays a crucial role in fostering these enduring and lasting alliances with other nations.
