Gun woman in flotilla (6)
I believe the answer is:
armada
'flotilla' is the definition.
(I've seen this in another clue)
'gun woman' is the wordplay.
'gun' becomes 'arm' (I've seen this in other clues).
'woman' becomes 'Ada' (woman's name).
'arm'+'ada'='ARMADA'
'in' is the link.
(Other definitions for armada that I've seen before include "lot of craft" , "Old Spanish fleet" , "A great fleet of warships" , "vessels" , "A great fleet - Spain had one" .)
