AHTS VOS Hunter is an Anchor Handling Tug Supply (AHTS) built in 1979. Such vessels are mainly used for installation and towing work on offshore drilling platforms, as well as to provide rescue and support services in emergency situations.

It is a new type of small missile frigate of the Russian Navy, designed by the Almaz Design Bureau. It has been in service since 2018 and is designed to complement the Buyan-M-class frigates for offshore operations to provide more ocean-going capabilities. Design features include a stealthy superstructure and integrated mast, equipped with phased array radar panels, emphasizing high maneuverability, stability and wave resistance. The main weapons include Kalibr-NK cruise missiles launched from the eight-unit UKSK vertical launch system, capable of hitting targets within a range of about 2500 kilometers. These ships enhance the Russian Navy's operational capabilities across multiple fleets.

As the first and largest frigate of the Russian Navy, the 20380 class frigate still plays a significant role in the Pacific Fleet and Baltic Fleet to this day. Although small in size, it still has strong air defense, anti submarine and other performance based on strong configuration, and can even be used to combat large tonnage warships. The captain width of the 20380 escort is 111.6 meters and 14 meters respectively, equipped with diesel engines, with a maximum cruising speed of 27 knots and an effective range of over 4000 nautical miles. It can take off and land the Ka-27 helicopter and has good anti submarine capabilities.
