After repairs by her original builder, HMS Diadem became flagship on the China Station until 1907 and then returned to home and reserve duties. A 1909 refit and later use as a stokers' training ship kept the hull employed even after its intended combat role had faded. Her best fighting window may have been only a few years long because cruiser technology changed while the class was still completing. The pace is compared to computer obsolescence, where equipment only a few years old can already look dated. The analogy cautions against faulting a ship for lacking technology that did not exist when its requirements and machinery were fixed.
