Originally a 5,200-ton light cruiser designed by the Baltic Fleet of the Imperial Russian Navy to supplement the shortage of cruisers that had suffered heavy losses in the Battle of Tsushima, the light cruiser was finalized as a 7,000-ton light cruiser program after repeated haggling overhauls. On September 18, 1912, the Technical Committee of the Admiralty announced that the Ptilov Shipyard in St. Petersburg and the Russian Baltic Shipbuilding and Machinery Company in Reval had won the preliminary design bid for the new light cruiser. Finally, in early 1913, the orderer and the builder agreed on a price: 8.3 million rubles per ship (excluding the cost of ordering armor, artillery, and torpedo weapons). The total order was four, two each built by the Baltic Shipbuilding and Machinery Company and the Ptilov Shipyard in St. Petersburg.

The Swatlana scheme of finalization
USS Swatlana
Originally a Swatlana-class light cruiser of the Svetlana class, which was originally commissioned during the Imperial Russian period, construction began on November 11, 1913 at the Baltic Shipbuilding and Machinery Company, launched on November 28, 1915, forced to stop work due to the October Revolution, and in October 1924, the ship resumed construction at the Baltic Shipyard in Leningrad, and was named "Red Trade Union International" on February 5 of the following year. In October 1926, the ship was moved to the Vereşinsky Dry Dock in Kronstadt for outfitting and sea trials on 26 April 1927. On July 1, 1928, the ship was raised to the Soviet naval flag and was incorporated into service with the Baltic Fleet.

From 6 to 12 August 1929, the ship, under the command of Voroshilov, Chairman of the Revolutionary Military Commission of the USSR, sailed with 3 battleships, 9 destroyers, 9 submarines, and 3 transport ships belonging to the Baltic Fleet to the southwest of the Baltic Sea. Subsequently, the ship, together with the cruiser Aurora and four destroyers, under the command of Lal, squadron leader of the naval academy training ship squadron, made a friendly visit to Germany. On 18 August, the ship and the Aurora visited the port of Svenemünde. From September 6 to 12, the ship participated in the autumn exercises of the Baltic Fleet.

At the end of 1929, the Central Committee and the Government of the Cpsu, after studying the situation in the Black Sea region, decided to transfer the ships belonging to the Baltic Fleet and the battleship "Paris Commune" from Kronstadt to Sevastopol to join the Black Sea Fleet. On 18 January 1930, the ship arrived at Sevastopol and, together with the "Red Ukraine" and the "Red Caucasus", which had been built in Nikolayev, formed the cruiser corps directly under the Black Sea Fleet. On 31 October 1939 the ship was renamed The Red Crimean.

After the outbreak of the Great Patriotic War, the ship repeatedly shelled the positions of the German and Romanian armies from the base of Sevastopol to prevent the advance of the Axis forces, and at the same time repeatedly transported reinforcements from Novorossiysk, Batumi and Poti to the front line of Sevastopol and the Kerch Peninsula, and then transported the wounded and valuables to the rear. On 5 November 1944 the ship returned to Sevastopol with the battleship Sevastopol, the poor peasant, the Zhelezniakov, the flying, easy-going, the Dexterous destroyer, and eight large hunting submarines.
Using the Red Crimean in 1945, the light cruiser
After the war, the ship was classified as a light cruiser on 12 January 1949 according to the new classification naming standard of the Soviet Navy, and on 31 May was incorporated into the Black Sea Fleet Training Ship Squadron. On April 8, 1953, the ship was withdrawn from the Naval Combat Sequence and switched to training cruisers. From June 1956 to June of the following year, all the crew members stationed on board were assigned to a task force set up to salvage the battleship Novorossiysk, which exploded and sank in the port of Sevastopol. On 7 May 1957 the ship was disarmed and renamed the test ship ОС-20. On 11 March 1959, the hull was converted into a floating barracks ПКЗ-144. On 7 July, the ship was removed from the Navy's list of ships and dismantled in the same year. The Guards Naval Flag, which belonged to the ship, was raised on October 20, 1970, on the newly built Type 61 large anti-submarine ship, the Red Crimean.
Admiral Butakov
Originally a light cruiser of the Svetlana class "Admiral Butakov", which was originally commissioned during the Imperial Russian period, the ship was started on November 29, 1913 at the Puttilov Shipyard in St. Petersburg, launched on August 5, 1916, forced to stop work due to the October Revolution, renamed "Truth" on October 26, 1926, renamed "Voroshilov" on November 24, and the hull of the ship was towed to Kronstadt for sealing in 1928. Between 1928 and 1929 the possibility of converting the ship into a mine-laying-gliding carrier was studied. A proposal for the completion of the ship on 13 June 1930 was discussed and approved and included in the supplementary plan for the five-year plan for the construction of naval ships from 1929 to 1933, but was abandoned because the hull was too old. In February 1939, the Navy reviewed the plan to continue the construction of the ship again, and decided that it could be converted into a training ship. On August 25, the Naval Military Commission, on the recommendation of the Naval Science and Technology Committee, roughly determined the tactical and technical elements of the new training cruiser with project number "Project 78" and entrusted the latter to produce a more specific tactical technical task book by October 1, and the detailed design work was entrusted to the 32nd Central Design Bureau. On 25 September 1940, the ship was renamed Aurora, and the preliminary design was approved on 30 December 1940, but due to the high budget for the renovation, the conversion plan was finally cancelled, and the ship's hull was completely abandoned, and on April 25, 1942, the ship parked in the commercial port of Leningrad was hit by multiple large-caliber shells and aerial bombs from the German army, causing the subhull of the ship to enter the water and cause the overturn and sink. It was not until three years after the end of the war that the ship was salvaged out of the water by the rescue team. After judging that the repair was hopeless, it was sold in 1952 to the Leningrad Ferrous Metal Recycling Bureau for dismantling and recycling.

Admiral Spyridov
The ship was laid with keels on 16 November 1913 at the Putylov Shipyard in St. Petersburg under the name "Admiral Spiridov" light cruiser, and was launched on 27 August 1916. After 1924, it reopened at the Northern Shipyard in Leningrad and was renamed "Grozny Oil" on February 14 of the following year. After its completion on December 24, 1926, it was incorporated into the Soviet merchant fleet, with its home port in Batumi, mainly responsible for oil transportation in the Caucasus-Azov Sea. On 31 January 1934 it was changed to a non-self-propelled barge and renamed the Grozny. After the outbreak of the Great Patriotic War, the ship sank in Mariupol on 8 October 1941 on instructions from the Command of the Black Sea Fleet. After the Germans occupied the city, the ship was salvaged and repaired, and on September 30, 1942, the ship was designated as the "wm202" oil supply ship. In the autumn of 1943, the Germans sank the ship again before the Soviets recaptured Mariupol. On July 1, 1944, the ship was again salvaged out of the water. Continued to be used as an bunker until it was dismantled on June 19, 1952.

Admiral Greg
Laid on 24 November 1913 at the Russian Baltic Shipbuilding and Machinery Company in Revar under the name of the light cruiser Admiral Greg, the ship was launched on 26 November 1916 and transferred from Reval to Petrograd in December 1917. After 1924, it was reopened at the Baltic Shipyard in Leningrad, and on February 14 of the following year it was renamed "Azerbaijan Oil". After its completion on December 24, 1926, it was incorporated into the Soviet merchant fleet, with its home port in Batumi, mainly responsible for the transportation of oil from the Caucasus to the Mediterranean. On 31 January 1934 the vessel was incorporated into the Soviet Tanker Company under the Black Sea State Oil And Shipping Bureau, and the home port was changed to Tuapsie. At 5:45 a.m. on 23 December 1937, the ship was hit by a storm while anchoring at an anchorage outside the port of Tuapshey, and after de-anchoring collided with the breakwater on the shore, causing the hull to break, and after judging that there was no possibility of repair, the ship was removed from the list and dismantled and sold on November 11, 1938.
