See dry rot crippled warship (9)
I believe the answer is:
destroyer
'warship' is the definition.
(destroyer is a kind of warship)
'see dry rot crippled' is the wordplay.
'crippled' is an anagram indicator.
'see'+'dry'+'rot'='seedryrot'
'seedryrot' with letters rearranged gives 'DESTROYER'.
(Other definitions for destroyer that I've seen before include "Military vessel" , "Wrecker" , "heavily armed warship" , "Red oyster (anag)" , "Butcher'" .)
