Flying latest hot type of military plane (7)
I believe the answer is:
stealth
'type of military plane' is the definition.
(as in stealth aircraft)
'flying latest hot' is the wordplay.
'flying' indicates an anagram (letters fly around into new positions).
'hot' becomes 'h' (abbreviation, eg on taps).
'latest' with letters rearranged gives 'stealt'.
'stealt'+'h'='STEALTH'
(Other definitions for stealth that I've seen before include "Halt set in furtive manner" , "Low-visibility military technology" , "Unseen machination" , "Secretiveness, furtiveness" , "Cautious and surreptitious action or movement" .)
