A close view of the lattice mainmast of the Royal Navy Type 15 frigate Ursa (1943) of the 8th Frigate Squadron (West Indies). The ship is alongside a pier at the United States Key West naval base, Florida, taking on bunkers while on a courtesy visit during exercises involving the 7th Frigate Squadron (South Atlantic) and the 8th Frigate Squadron (West Indies). The photographer is on the port side of 01 deck just ahead of the funnel looking aft, up and to starboard showing the funnel on the left, with its yellow frigate bird logo of the West Indies Squadron.
