The Jan Mayen class is a class of offshore patrol vessels used by the Norwegian Coast Guard. The Coast Guard first announced plans for the class in September 2016, to increase their capability to patrol Norway's expansive coastal waters, and to replace the ageing Nordkapp-class vessels. [1]

Considerably larger than their predecessors, the hulls of these ships were constructed at the Vard Tulcea shipyard in Romania. [2] The hulls were then towed to Norway where the ships were outfitted and tested at the Vard Langsten shipyard. [3] [4]

The total cost for the 3 ships in the class is expected to be 7.2 billion kroner ($645 million), one of the largest maritime defense expenditures ever made by Norway. [5]

Design

The design of the ships was contracted to LMG Marin, a Norwegian engineering services company. [6]

The hull of the Jan-Mayen-class is designed to be ice-strengthened, to enable independent navigation of icy seas. The deck is large enough at stern to accommodate an AW101 helicopter, and it includes a hangar that can house a further two NH90s. [6]

These ships are armed with a single Bofors 57 mm L/70 gun for use against surface and airborne targets, as well as .50 calibre machine guns for use against soft surface targets. [7] They will utilize the 9LV Combat Management System for fire control. [6]

For navigation, Jan-Mayen-class ships will utilize a Marins-series inertial navigation system, along with a Quadrans gyrocompass and a Netans navigation data distribution and computation system. Communication onboard the ship, along with external communications, will be handled by the TactiCall Integrated Communication System, from Saab AB. [6]

The ships are designed for a crew of 100, [8] are will be able to support operations longer than 60 days. [6]

Ships in class

The ships are named after the Norwegian arctic islands of Jan Mayen, Bjørnøya and Hopen. [5]

Jan Mayen is a Norwegian volcanic island in the Arctic Ocean with no permanent population. It is 55 km (34 mi) long (southwest-northeast) and 373 km2 (144 sq mi) in area, partly covered by glaciers. It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by a 2.5 km (1.6 mi) wide isthmus. It lies 600 km (370 mi) northeast of Iceland, 500 km (310 mi) east of central Greenland, and 900 km (560 mi) northwest of Vesterålen, Norway. The island is mountainous, the highest summit being the Beerenberg volcano in the north. The isthmus is the location of the two largest lakes of the island, Sørlaguna and Nordlaguna. A third lake is called Ullerenglaguna. Jan Mayen was formed by the Jan Mayen hotspot and is defined by geologists as a microcontinent.
