Hryhoriy Kuropyatnykov (BG-50) is a Pauk-class Cold War-era ocean-going corvette warship serving the modern Ukrainian Navy. The Pauk-class (Project 1241.2) was built for the Soviet Navy / Coast Guard, as well as Soviet-aligned export customers, by the shipbuilders of Vostochnaya Verf and was based in the lengthened, diesel-powered Tarantul-class ships (Project 1241.1). Construction took place from 1977 to 1989 resulting in a fleet of 29 total hulls, some of which were ultimately transferred to willing operators after the fall of the Soviet Union. As part of the Paulk-class, the Hryhoriy Kuropyatnykov serves in the Anti-Submarine Warfare (ASW) role. Commissioned in 1984, the vessel displaces at 580 tons.

The structural mass of the ship is concentrated over midships. This results in a stepped approach towards both the bow and the stern. The main mast works are seated just aft of midships and specialized sensors / systems are set just ahead of it. Over the forecastle is a single turreted deck gun. The hull line runs unbroken from bow to stern resulting in a relatively clean-looking design.

The warship has a length of 187 feet, a beam of 30.9 feet, and a draught of 7.9 feet - making her relatively compact and able to operate close-to-shore. The propulsion scheme involves 2 x M504 series diesels outputting 20,000 horsepower to 2 x Shafts astern. Maximum speed in ideal conditions is up to 34 knots depending on laden weight. Range is a useful 1,600 nautical miles.

Aboard is a complement of forty men. Radar systems include a surface-search fit and sonar is also installed for submarine-hunting sorties. The Electronic Warfare (EW) suite is comprised of the Vympel-R2 series. OK-16 decoy launchers are also noted.

Armament is a single 76mm turreted deck gun along with 1 x SA-N-5 Surface-to-Air Missile (SAM) launcher, 1 x 30mm AK-630 Close-In Weapon System (CIWS), 4 x 406mm torpedo tubes, and 2 x RBU-1200 Anti-Submarine ROCket (ASROC) launchers.

Hryhoriy Kuropyatnykov currently serves as part of the Ukrainian Sea Guard and, at one point, was joined by sisters BG-51 and BG-52 (she remains the lone survivor as of 2023). At least one of these was taken over by invading Russian forces at Crimea.
