Speedy ships? (5)
I believe the answer is:
fleet
I believe this clue is a double definition.
'speedy' is the first definition.
(I've seen this in another clue)
'ships?' is the second definition.
(eg a naval fleet)
(Other definitions for fleet that I've seen before include "flying?" , "ships, lots of them" , "What makes London underground journey" , "fast is observed" , "Swift like naval force" .)
