I'm very pleased to say that our long-planned collaboration with the National Maritime Museum is now happening.
They have released a lot of info from their internal research on Royal Navy warships on their website: http://www.nmm.ac.uk/researchers/research-areas-and-projects/warship-histori... (it says CC-BY-NC but the NC bit is a typo and will soon be corrected)
I've set up a project page for this on-wiki, please do have a look and join in :-) http://en.wikipedia.org/wiki/Wikipedia:GLAM/NMM
Thanks
Chris
