Orders yet carried out by ship (9)
I believe the answer is:
destroyer
'ship' is the definition.
(destroyer is a kind of ship)
'orders yet carried out' is the wordplay.
'orders yet' can be anagrammed to 'DESTROYER'.
Though, I am not sure how the anagram is indicated.
'by' is the link.
Can you help me to learn more?
(Other definitions for destroyer that I've seen before include "Siva?" , "heavily armed warship" , "Ravager" , "Large warship" , "Military vessel" .)
