Speedy armada? (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)
'armada?' is the second definition.
(fleet of ships)
(Other definitions for fleet that I've seen before include "Group of vehicles operating together, ships say" , "Navy's ships" , "Collection of cars/ships" , "Rapid in movement" , "Squadron" .)
