A close-up of the port midships, taken from off the broadside, of the Royal Navy frigate Nubian (1960) under way during exercise Sally Forth in the North Sea off the Firth of Forth. Her pendant number is F131, and she has the 7th Frigate Squadron number on her funnel. Everything forward of her bridge and abaft her limbo mortar well is just out of the picture. The photographer is on board the guided missile destroyer Bristol (1969).
