The ''' Perekop (Перекоп) was a sea-going monitors of the Khasan class. She was named The [Perekop|town of the same name]] in the Crimean Autonomous Soviet Socialist Republic. Perekop was active throughout World War II but did not participate in combat. The Khasan class monitors were notable for being the largest river-going monitors ever built. All three ships of her class survived the war and would continue to serve in the Soviet Navy until 1960. Perekop was laid down 15 June, 1936, the same date as both her sister ships, Khasan and Sivash.

Design
Perekop was designed to operate on the Amur River and on the Strait of Tartary between Outer Manchuria, Sakhalin and Japan to protect against the threat the Japanese empire posed against the Russian Far East. Relations between the two countries was poor and a low intensity conflict was waged by the Soviet Union and Japan since 1932 over Japan's creation of Manchukuo. Planning on her design began in 1935, using an old, unused design from 1915 as its basis. Perekop was originally to be armed with three twin 130mm B-28 guns, two twin 39-K anti-aircraft guns at the aft, and three twin 41-K anti-aircraft guns. In addition she carried an array of heavy machine guns and carried naval mines. Plans for a fourth twin 130mm turret and a seaplane hangar were scrapped due to overloading issues.

Perekop was protected by steel belt armour ranging from 77 mm amidships to 36 mm at both ends of the ship. The citadel was closed by 25 mm bulkheads. Perekop possessed an armoured deck was 40 mm thickness amidships and 25 mm of protection at the fore and aft. The conning tower and turrets had 50-100 mm protection, and machine gun turrets had 10 mm armour protecting them.

Perekop had small forecastle allowing for limited high seas capabilities along the Strait of Tartary and the Amur River Basin. The flat bottom hull and bows of the ships were stiffened, giving the monitors icebreaking capabilities.

Construction
Perekop was laid down 15 June, 1936 at Krasnoye Sormovo Factory No. 112 shipyard, in Gorky (now called Nizhny Novgorod) along with her two sister ships and named Simbirtsev (Симбирцев) initially. Work on Simbirtsev continued at Gorky until the Summer of 1939 when sections of the monitor began to be sent East through the Trans-Siberian railway to Khabarovsk Factory No. 368, Khabarovsk to be completed. Perekop was disassembled into 260 pieces and arrived
