Project 1204 Shmel / Shmel-class patrol boat

Also known as
  • Shmel class
  • Shmel-class
  • Project 1204
  • Project 1204 Shmel
  • Project 1204M Shmel
  • Shmel
  • Dzhmil
  • Bumblebee class

The Project 1204 Shmel class is a Soviet armored river gunboat family designed by Almaz Central Marine Design Bureau for shallow rivers, lakes, and coastal waters. It put a PT-76-derived 76 mm turret, a BM-14-17 rocket launcher, automatic cannon, machine guns, and mine rails on a compact shallow-draft hull, making it a fire-support and patrol craft rather than an oceangoing combatant. Russian Shmel boats were documented in the Kerch and Sea of Azov security context during the Russo-Ukrainian War, while Ukrainian Sea Guard Dzhmil examples survived in Danube-area service and training.

Role in Conflicts

Side
Russia

Russian Project 1204 Shmel boats are directly documented in the Kerch and Sea of Azov force posture: bmpd said AK-201 and AK-248 arrived in Kerch in May 2018, InformNapalm described their Volga-Don transfer during the Azov crisis, and Covert Shores listed Project 1204 river gunboats in the 25 November 2018 Kerch crisis order-of-battle context. The sources used here do not identify Shmel boats as the vessels that fired on or rammed Ukrainian craft.

Design And Service Notes

The Shmel is best read as a river and shallow-water artillery craft: compact enough for inland waterways, but armed like a small fire-support platform.

Design Line

Victory Museum assigns the design to TsMKB Almaz, with Y. Y. Benois followed by L. V. Ozimov as project leadership changed during development.

Production Sites

Sources identify Zaliv Shipyard in Kerch, a Mykolaiv yard, and Leningrad production context; RussianShips itemizes 98 boats from Zaliv and 20 from Mykolaiv.

Original Mission

Victory Museum describes a boat intended for river and lake patrol, river-craft attacks, ground-force fire support, armed crossings, and shallow coastal operations.

Weapon Layout

A PT-76B-derived 76 mm turret sits forward, a BM-14-17 rocket launcher is mounted amidships, and automatic guns or machine guns provide close defense.

Ukrainian Service

Ukrainian reporting identified Nizhyn, Izmail, and Lubny repair activity in 2019, and Defense Express later reported four Dzhmil boats retained for Riverine-2021 training.

Dnieper Reporting

TASS reported Russian plans to assign Shmel boats to a reformed Dnieper River Flotilla; Defense Express cautioned that open sources had not yet recorded Russian Shmel combat use in Ukraine.

The compact conflict-use row therefore rests on direct Kerch and Azov evidence rather than treating later Dnieper planning as confirmed combat use.

Variants

Public sources mainly separate the baseline Project 1204 production boats from national service names; Dzhmil is treated here as Ukrainian service naming for retained boats rather than a separate hull design.

Timeline

Project 1204 Shmel / Shmel-class patrol boat Key Events

  1. Technical design approved

    Victory Museum describes the 1965 navy and shipbuilding-ministry requirement for a new river artillery boat and says the Shmel technical design was approved by the end of 1965.

  2. Serial production begins

    Victory Museum says large-series construction began at Zaliv Shipyard in Kerch in 1967 before production also ran at Mykolaiv and Leningrad facilities.

  3. Production run ends

    Victory Museum and MilitaryFactory place the class's production run in the late 1960s and early 1970s, with 118 boats built.

  4. Caspian Flotilla boats move to Kerch

    bmpd reported that AK-201 and AK-248 Project 1204 boats arrived in Kerch from the Russian Caspian Flotilla for Sea of Azov and Kerch Strait security.

Built for border-guard and coast-guard work, the small aluminium-hulled craft carries heavy machine-gun armament, simple navigation or surface-search radar, and enough speed for short-range littoral security rather than open-ocean combat. Ukrainian Sea Guard and Navy examples remained visible after independence, and several Project 1400M boats entered the Russia-Ukraine War record as captured or destroyed Ukrainian maritime-security craft in 2022.

The design reused the Project 205 Osa hull but traded the missile-boat mission for 400 mm torpedo tubes, depth-charge equipment, sonar, and twin 30 mm AK-230 gun mounts. Its Russia-Ukraine War record is best documented as Black Sea patrol and loss/capture evidence: Ukrainian Donbas was reported seized at Mariupol in April 2022, while a Russian Project 205P/Tarantul boat was reported sunk at Sevastopol after late-December 2023 Ukrainian strike activity.
