Two former Royal Navy flagships, a frigate and a pair of support tankers will be decommissioned in cost-saving measures announced by Defence Secretary John Healey.

The savings, which Mr Healey blamed on the “dire inheritance” left by the Tories, will see assault ships HMS Albion and HMS Bulwark, which have both been flagships, decommissioned.

Ageing Type 23 frigate HMS Northumberland is beyond economic repair and will be decommissioned along with two Wave class tankers.

The Army’s Watchkeeper drones, which cost around £5 million each and have been in service for a decade but have been beset by problems and are effectively obsolete, will be grounded.

Helicopters will also be affected by the cuts, with the 14 oldest Chinook transport aircraft removed early from service and Puma’s lifespan not being extended beyond March 2025.
