The fighter's craft (8)
I believe the answer is:
warships
'the' is the definition.
I can't judge whether this defines the answer.
'fighter's craft' is the wordplay.
I cannot really see how this works, but
'craft' could be 'ship' (ship is a kind of craft) and 'ship' is found in the answer.
The remaining letters 'wars' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for warships that I've seen is " Naval vessels".)
