Fast-moving naval task force (5)
I believe the answer is:
fleet
This clue could be a double definition.
'fast-moving' is the first definition.
(fleet can mean fast)
'task force' is the second definition.
(I've seen this before)
'naval' acts as a link.
This may not be right. It may belong to one of the definitions.
Can you help me to learn more?
(Other definitions for fleet that I've seen before include "Fast as a naval unit" , "Swift; group of ships" , "Fast - group of boats" , "collection of aircraft" , "Swift - London street" .)
