No embargo, free to supply missile (9)
I believe the answer is:
boomerang
'missile' is the definition.
(I know that boomerang is a type of missile)
'no embargo free' is the wordplay.
'free' indicates an anagram.
'no'+'embargo'='noembargo'
'noembargo' with letters rearranged gives 'BOOMERANG'.
'to supply' is the link.
(Other definitions for boomerang that I've seen before include "Recoil from" , "Self-returning missile" , "Aboriginal projectile" , "Backfire" , "Primitive weapon" .)
