Navy planes in dilapidated state (12)

I believe the answer is:

pennsylvania

'state' is the definition.
(Pennsylvania is an example)

'navy planes in dilapidated' is the wordplay.
'dilapidated' indicates an anagram.
'navy'+'planes'+'in'='navyplanesin'
'navyplanesin' with letters rearranged gives 'PENNSYLVANIA'.

(Other definitions for pennsylvania that I've seen before include "State of NE US" , "State of NE? USA" , "State of northeastern US" .)

I've seen this clue in The Telegraph.
