Hey
smudger1309.......your Bourke looks superb.......I have walked on a real version....back in 1986.....

Back to your question.....
R&D is Research & Development....I wouldn't worry too much as your other thread is under Battleships.....which really could have another name.....but all smaller warships can be considered off-spring of the larger
