The UK Royal Navy's third Type 45 Daring-class anti-air warfare destroyer, HMS Diamond (D34), has successfully completed its multi-million pound upgrade programme.
Last year, the Portsmouth-based Type 45 destroyer participated in the international task group to provide force protection for merchant vessels transporting chemical weapons and substances out of Syria for destruction.
HMS Diamond commanding officer commander Marcus Hember said: "The day the ship's company move back on board is a big day for us.
"It marks the point at which we can take back full ownership of our ship and begin the process of regeneration.
"Whilst it is a long process, we are all, ultimately, working towards our deployment in 2016, getting back out on operations and doing what the Royal Navy does best."
As part of the extensive maintenance and improvements programme, the destroyer was equipped with the Harpoon missile system and received upgrades to communications and IT equipment.
The destroyer also received a new gas turbine and stabilisers including upgraded high-pressure salt water and air systems.
HMS Diamond will now undergo sea trials to fully test and validate the new systems and equipment. The crew will also test their combat and damage control capabilities as part of operational sea training.
Capable of operating a range of helicopters from its flight deck, the 152.4m-long and 21.2m-wide HMS Diamond has been designed to support a wide range of missions, including humanitarian and anti-smuggling.
With a displacement capacity of 7,350t, the destroyer can cruise at speeds of around 33mph and accommodate a crew of 235.
The Type 45 destroyer fleet replaced the Type 42 frigates, which were in service with the navy since the mid-1970s.
