Heavy RAS – Royal Navy

A few pictures of the Royal Navy’s new Heavy Replenishment at Sea (RAS) rig during testing and development at HMS Raleigh.

Navy News had a great article on the new system;

The aim of the new complex is to transfer 25 five-tonne loads every hour for five hours across a 55-metre (180ft) gap separating two – that’s one pallet every two minutes and 24 seconds, or 625 tonnes of stores in all.  Even with fully-honed teams on both ships, the best you could hope for presently would be 200-250 tonnes.


Rolls Royce won the £25m contract to develop the system and build the training facility

This shows a great commitment to the enabling capabilities that allow the Royal Fleet Auxiliary to support the Royal Navy on long and distant deployments, a capability missing in many other maritime forces. The training facility is also said to be unique.

The big jump is not only in speed but capacity, previously, loads were limited to 2 tonnes, the new system will be able to handle 5 tonnes. Due for handover next Spring the images below, courtesy of Rebecca Ricks of the Plymouth Herald and with thanks, show the system in action.
