This photograph shows HMCS Prince Robert, probably in mid-1943 shortly after its conversion to an anti-aircraft cruiser, at Esquimalt, British Columbia.

The upgraded Prince Robert, intended to help defend Allied ships against German aircraft, supported convoys between Great Britain and Gibraltar, at the western end of the Mediterranean Sea. The ship's main anti-aircraft armament consisted of ten 4-inch guns on five twin mountings; two are visible on the right. Upgraded radar (upper centre) could detect and track enemy aircraft.
