 The economy of the city is still based on engineering, including a large aerospace industry, as well as the service sector.The city is named after Wulfrun, who founded the town in 985, from the Anglo-Saxon "Wulfrūnehēantūn" ("Wulfrūn's high or principal enclosure or farm").Prior to the Norman Conquest, the area's name appears only as variants of "Heantune" or "Hamtun", the prefix "Wulfrun" or similar appearing in 1070 and thereafter.
