Type of battleship (11)
I believe the answer is:
dreadnought
'type of battleship' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dreadnought that I've seen before include "Early twenieth century battleship" , "Type of battleship" , "One has no fear whatever" , "Vessel" , "(Class of) battleship launched in 1906" .)
