The plant has a huge experience of military construction that was obtained not only in the period of the Soviet Union, but also during the period of modern Ukraine: the Ukrainian navy's flagship Hetman Sahaydachny patrol frigate was constructed at our shipyard," the general director said.

Having served earlier in his career as production officer for the USS Arleigh Burke (DDG 51) and project Naval architect overseeing structural design for the Canadian Patrol Frigate, HMCS Halifax (FFH 330), he had the unique experience of having performed a principal role in the design, construction, test, and delivery of three first-of-class warships.

Both shipyards roughed out a fairly typical construction for the patrol frigate - a steel hull with rib-like frames every 8-ft - but the compromises began immediately.

Since October 2001 Canadian patrol frigates and supply vessels have rotated in and out of the region, providing support to other multinational force ships or conducting interdiction actions, such as boarding vessels to apprehend suspected members of terrorist groups.

A prime example is the $404 million contract for a fleet of 12 patrol frigates awarded in 1983 to a New Brunswick shipbuilding firm.

The Halifax Class frigate (hull designation FFH) is a class of multi-role patrol frigates that have served the Canadian Forces since 1992.

Ships by name Helicopter carrier Jeanne d Arc, anti-submarine warfare frigates (type F70 vessels Dupleix, Montcalm, Jean de Vienne, La Motte-Picquet, Georges Leygues, Primauguet and Latouche- Treville), type F70 anti-air warfare frigates Cassard and Jean Bart, patrol frigates (type A69 vessels Commandant Bouan, Commandant Birot, Enseigne de vaisseau Jacoubet, Commandant Ducuing, Lieutenant de vaisseau Le Henaff, Premier maitre l Her, Commandant Blaison, Commandant l Herminier and Lieutenant de vaisseau Lavallee), type F67 ASW frigates De Grasse and Tourville and Horizon air defence frigates Forbin and Chevalier Paul.

The following year a Defence White Paper cited the NSA as part of the program to counter the Soviet threat, with the new helicopters extending the anti-submarine role of Canada's 12 new patrol frigates.
