Prototypes for aircraft that entered service under a different design number are ignored in favour of the service version.  The date the aircraft entered service, or was first flown if the service date is unknown or it did not enter service follows the name, followed by the country of origin and major wartime users.  Aircraft used for multiple roles are generally only listed under their primary role unless specialized versions were built for other roles.
