USS Maryland (BB-46), the third Colorado-class battleship, was launched in 1920 and commissioned in 1921. Prior to the Second World War, she served as the fleet flagship, participating in numerous exercises and making visits to Australia, New Zealand and Brazil. On December 7th, 1941, USS Maryland was in Pearl Harbor, where she received minor damage from Japanese bombs, while her neighbor Oklahoma capsized. After repairs, Maryland returned to service in 1942, took part in the Battle of Midway, and patrolled Fiji.

From 1943, USS Maryland went on the offensive. She participated in artillery support for the landings on Tarawa, Kwajalein, and Saipan, but was damaged by a torpedo. During the Battle of Leyte Gulf, she repelled the Japanese fleet in the Surigao Strait, but was damaged by a kamikaze attack. During the Battle of Okinawa in April 1945, USS Maryland was again damaged by a kamikaze strike, forcing her to go for major repairs. In August 1945, after completing her modernization, USS Maryland headed back to the combat zone. After the surrender of Japan, she took part in the operation to return American servicemen to their homeland. After the war in 1947, she was decommissioned and sold for scrap in 1959.

The Treaty of Washington limitations forced naval command to revert to the plans for the previously canceled ships in a highly modified form, leading to the development of battleships HMS Nelson and her sistership HMS Rodney.

HMS Nelson was completed in June 1927. Her armament consisted of a total of nine 16 inch guns in three triple gun turrets and twelve 6 inch guns in twin turrets. She was the first British warship to have a tower bridge that incorporated gun directors and a mast, and had flush decks like the previous “Lord Nelsons” from 1908. She was powered by Brown-Curtis geared turbines driving two shafts and had a speed of 23.5 knots for 46,000 HP.

HMS Nelson served as flagship in both the Atlantic and Home Fleets for 14 years, participating in various operations. She took part in the search for Scharnhorst and Gneisenau. Later in the Second World War, HMS Nelson was deployed to the Mediterranean Fleet, participating in operations like the Torch landings and the invasion of Sicily. Throughout the war, HMS Nelson was involved in key operations, including escorting convoys and engagements against German forces. She narrowly avoided major disasters while participating in D-Day bombardments before undergoing repairs in the U.S. Following service in the East Indies Fleet, Nelson contributed to the Japanese surrender in Malaya.

After the war, she served briefly as flagship before being sold for scrap in March 1949, marking the end of her noteworthy career in naval history.
