Vampire's later fit provides an example of changing destroyer priorities during the 1960s. Giving up torpedoes made room for more radar, which mattered increasingly for warning against aircraft. Torpedoes had become less central to a surface combatant's ship-killing arsenal in this account, while the ship still carried 40 mm guns. The visible alteration links Cold War sensor needs to the trade-offs involved in refitting a general-purpose destroyer.
