SSK HSY-70B was an improvement of previous -70A submarine and originally 6 were built. All early 70A hulls were also upgraded to -70B spec, created the HSY-70A2 type. Electronics were also upgraded, as also diesel engines and a new quieter propeller was fitted. Other changes in propulsion system included a new more efficient electric motors of same power and new batteries from Sunlight with even larger efficiency. Finally, they were fiited with HUSM-2B turbojet underwater to surface missiles with range up to 120km, while original HUSM-2A had 70km and Exocet SM-39 50km. In late 1990's the submarines were fitted with the enhanced HUSM-2C missiles with range up to 160km.

In Cyprus AU there is a marine branch of Cypriot Police, called Marine Police, with Coast Guard duties, including SAR and anti-terrorist operations in oil rigs. In latter duty Marine Police acts together with National Guard Amphibious Special Forces. The Marine Police operates a fleet of patrol vessels from 98m to RHIB, numbered similarly with Japan Coast Guard. However, Cypriot Marine Police does not use the tem "PLH" for Patrol Large Helicopter", despite having some patrol vessels with full helicopter facilities. Vessels come from various sources, including : Hellenic Kingdom, UK, Israel, Russia and domestic.

PL (Patrol Large) : Every vessel above 45m.
PV (Patrol Vessel) : Every vessel between 20m-45m.
ML (Motor Launch) : Every vessel below 20m.
RHIBs are named with a number only.

In 2000's Cyprus ordered 6 Pr.12200 Sobol Class and 12 Pr.12150 Mangust Class from Russia, of which 3 and 9 respectively built locally under license.
