A Royal Air Force Chinook CH47 helicopter has delivered new essential radar equipment to the top of the Rock of Gibraltar.
Images of the aircrew from 27 Squadron show them delivering the fragile components to the top of the Upper Rock located in the British territory of Gibraltar.
The radar equipment is essential to maintain the safety and security of the air space for military airfields in the UK and Sovereign Base Areas.
The Chinook CH47 from RAF Odiham, Hampshire, completed the task as a part of a larger project that involves upgrading air traffic management systems across 65 units in the UK and around the world.
A helicopter was required because the equipment was too big to be transported via road through the narrow tunnels.
RAF Gibraltar Station Commander Wing Commander Doherty said: "I am genuinely delighted at the manner in which this difficult task has been achieved, safely.
"A talented and very broad team have ensured that disruption to the people of Gibraltar was minimised and military operations were uninterrupted."
Chinook helicopters are extremely capable and highly versatile support helicopters, with each aircraft able to carry up to 55 people or 10 tonnes of mixed cargo.
