The Khasan-class (Project 1190) were a class of three sea-going river monitors built between 1936 and 1942 for the Soviet Navy, the Khasan, Perekop and Sivash.

The Khasan class had small forecastles 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.

Due to the outbreak of the Second World War, completion of the ships was difficult, combined with the limited capabilities of the Khabarovsk shipyard, the monitors would not launch well into the 1940s.

During this time the ships had been renamed, Lazo had become Khasan (Хасан), Simbirtsev had become Perekop (Перекоп) and Seryshev had become Sivash (Сиваш).

During the Second World War, Khasan and Perekop served with the North Pacific Flotilla but did not participate in the Soviet invasion of Manchuria and Korea.
