HMS Upholder (P37) was a Royal Navy U-class submarine built by Vickers-Armstrong at Barrow-in-Furness. She was laid down on 30 October 1939, launched on 8 July 1940 by Mrs. Doris Thompson, wife of a director of the builders. The submarine was commissioned on 31 October 1940. She was one of four U-class submarines which had two external torpedo tubes at the bows in addition to the 4 internal ones fitted to all boats. They were excluded from the others because they interfered with depth-keeping at periscope depth.
The British L-class submarine was originally planned under the emergency war programme as an improved version of the British E-class submarine. The scale of change allowed the L class to become a separate class.
HMS Afridi was a Tribal-class destroyer of the Royal Navy launched in 1907 and sold for scrap in 1919. During the First World War she served in the North Sea and the English Channel with the 6th Destroyer Flotilla and as part of the Dover Patrol.
The D-class submarine was the Royal Navy's first class of submarines capable of operating significantly beyond coastal waters. They were also the first boats to be fitted with wireless transmitters.

HMS Splendid was a third-batch S-class submarine built for the Royal Navy during World War II. She was laid down on 7 March 1941 and launched on 19 January 1942. After an initial patrol through the Bay of Biscay to Gibraltar, Splendid conducted two patrols in the Mediterranean Sea; one was abandoned after technical problems and on the other she sank two Italian ships. On her next patrol, the submarine attacked two Italian convoys, sinking an Italian destroyer in the second attack. Based in Algiers, the boat operated north of Sicily, sinking six Italian ships, including two tankers and two heavy merchant ships. Splendid was detected by a German destroyer on 21 April 1943 while patrolling off Naples, Italy; the submarine was attacked with depth charges by the destroyer and forced to surface, after which she was scuttled and her surviving crew members taken prisoner. She was the most successful British submarine by tonnage sunk between November 1942 and May 1943.
HMS Sickle was a third-batch S-class submarine built for the Royal Navy during World War II. Completed in 1942, she made her initial war patrol off the Norwegian coast.

From 10 May to 10 October, the boat patrolled the Gulf of Genoa five times and sank a German submarine as well as three minesweepers and an escort ship. She then moved to Beirut, French Lebanon, and conducted two patrols in the Aegean Sea, sinking three caïques and a merchant ship, in addition to landing resistance operatives in Greece.
HMS Stratagem was a third-batch S-class submarine built for the Royal Navy during World War II. Completed in 1943, she made her first war patrol off Norway before she was sent to the Far East, where she conducted three war patrols. On her second, she shelled installations on a Japanese-held island. Her only success came on her last patrol, when she torpedoed and sank a Japanese oil tanker. Soon after, she was spotted by aircraft and depth charged by a destroyer. She was forced to surface, and was scuttled to prevent her capture. Ten crew members escaped the sinking submarine and were taken prisoner, of whom only three survived the war.

The Action off Noordhinder Bank on 1 May 1915 was a naval engagement between four British naval trawlers, supported by a flotilla of four destroyers and a pair of German torpedo boats from the Flanders Flotilla. The action began when the two torpedo boats were sent to rescue the crew of a reconnaissance seaplane that had been forced to alight by engine trouble and to attack the trawlers. The Germans engaged the trawlers; British destroyers from the Harwich Force appeared; the German ships tried to escape but were sunk.
United States Navy operations during World War I began on April 6, 1917, after the formal declaration of war on the German Empire. The United States Navy focused on countering enemy U-boats in the Atlantic Ocean and the Mediterranean Sea while convoying men and supplies to France and Italy. Because of United States's late entry into the war, her capital ships never engaged the German fleet and few decisive submarine actions occurred.
