Chongqing, formerly known as HMS Caledon, belongs to the British Royal Navy C- class light cruiser and entered service in 1917. Equipped with 7 6-inch main guns, the highest speed of 29 knots. In 1927, the Chinese national government leased HMS Caledon to Britain and changed its name to "Chongqing. In the Anti-Japanese War, the Chongqing mainly carried out anti-submarine, escort and mine-laying missions in the Yangtze River Basin. In 1948, the Chongqing was officially purchased by the National Government of China. In April 1949, the officers and soldiers of the ship rebelled in Nanjing and joined the Chinese People's Liberation Army Navy, becoming the first cruiser of the People's Liberation Army.

The ship is named after Somnus, the "god of sleep" in Roman mythology, and is based on the modernization project of the British Navy's Dido-class and Edinburgh-class light cruisers. It is planned to be equipped with 133mm naval gun, but due to its low firing rate, it is difficult to cope with the rapid development of aviation technology in the late World War II (such as jet fighters and high-speed bombers), and it is later modified into 113mm RP10 Mark IV rapid-fire naval gun. The ship has not started construction, more as a technical verification.

The World War II-era "Bold" belonged to the D-class destroyer. It was commissioned in 1931 and was sunk during the Dunkirk Retreat in 1940. Built in the 1930 s, it belongs to Britain's main destroyer before World War II, with a standard displacement of 1,360 tons, equipped with 4 120mm main guns, 8 2-pound anti-aircraft guns and 2 quadruple 533mm torpedo tubes. The design focuses on speed and anti-ship capability, but the armor is weak and the anti-aircraft firepower is insufficient. On May 29, 1940, during the retreat from Dunkirk, he was sunk by German Ju 87 "Stuka" dive bombers, killing all his staff.

The Sverdlov class design began in the late 1930 s. It was originally planned to fight against German Hipper class heavy cruisers. However, due to the interruption of the Soviet-German War (1941-1945), actual construction began in 1948 and was completed in 1955 (after the war). It has a standard displacement of 13,600 tons and is equipped with 152mm main guns, anti-aircraft guns and torpedoes. The design focused on high speed (32 knots) and anti-ship capability, but the armor was relatively weak. A total of 14 ships were built, which was one of the main surface ships of the Soviet Union after the war. In the 1950 s, anti-aircraft missile test equipment (such as the "57mm anti-aircraft gun system") was installed, but no major upgrades were made.

The Daito class is a light cruiser designed by the Japanese Navy in the late World War II. It was originally planned to serve as a submarine carrier, carrying multiple reconnaissance aircraft to support submarine operations. Later, due to changes in strategic needs, it was transformed into a joint fleet flagship, which was used to command the remnant fleet in the Pacific battlefield. It is powered by a regular steam turbine with a maximum speed of 35 knots, but its actual combat effectiveness is limited due to fuel shortages.

The Iowa class battleships are the largest displacement class battleships in the United States Navy. Four Iowa class battleships have been completed, making them the longest, most powerful, fastest (reaching 33 knots), and latest decommissioned battleships in the world. Four ships of the same type are still preserved. Due to the cancellation of the Montana class, the successor ship to the Iowa class, this battleship became the last class of battleships in the United States Navy. On September 2, 1945, the signing ceremony of Japan's unconditional surrender, which marked the end of World War II, was held on the main deck of the USS Missouri anchored in Tokyo Bay, making the ship famous worldwide.
