After a 15 month Capability Upgrade Period (CUP), HMS Diamond has started acceptance trials.
The 15 month upgrade included work on the communication satellite systems, internal computers and weapons systems as well as adding Harpoon anti-ship missile system launchers.
The ship was launched in 2007 and after various trials, was accepted into service in 2011.
So less than 4 years after being commissioned she had to have a 15 month upgrade.
Is this normal for such a new ship?
Am sure the scope of work was wider than the press release suggests but would 15 months be normal for a communications and computing system upgrade?
