Construction History
Designed by a group of designers under the guidance of engineer S.V. Pugavko, as a further development of the hunter type MO-2. Unlike the MO-2, they slightly increased the length and width, as well as removed the deck cut in the stern, reduced the board by 100 mm, and the boats received more powerful main engines, which contributed to an increase in the full speed. In peacetime, hunters carried out guard service as part of the NKVD marine border guard units, and in wartime they were used to combat enemy submarines as part of the Navy, as well as to protect the water area (IWR).
Serial construction of boats was launched at the Leningrad NKVD plant No. 5. Prior to the outbreak of war, 187 boats were built on it: 75 municipal units replenished the composition of fleets and flotillas, 113 became part of the NKVD Marine Border Guard. Some of the small hunters who became part of the Red Banner Baltic Fleet (KBF) took part in the Soviet-Finnish “winter” war. Maritime border guards had to master the sea borders of Lithuania, Latvia and Estonia, which became part of the USSR in 1940. After the outbreak of war with Germany, serial construction of the MO-4 type was carried out at several plants in the country: No. 5, No. 345, No. 640, the Astrakhan shipyard of the People’s Commissariat of Industry and Moscow shipyard of the People's Commissariat of Fleet. Despite all the difficulties, during the difficult war years, 74 boats of the MO-4 type were built.
