Lindormen-class minelayer

The Lindormen class is a class of minelayers built for the Danish Navy. The Lindormen class is currently in service with the Estonian Navy.
History.
The class consists of two ships: KDM "Lindormen" (N43) () and KDM "Lossen" (N44) (). The purchase of the cable-minelayers was approved in the 1973 defence bill. The ships were built by Svendborg Skibsværft in 1977 and commissioned on 14 June 1978. One of the ships served as a command and support ship in STANAVFORCHAN, under Danish Navy. Both ships were decommissioned by the Danish Navy on 22 October 2004 and sold to Estonia in 2006. They were renamed and and would later find service in the Standing NATO Mine Countermeasures Group 1. Wambola was held in reserve until it replaced Tasuja in Estonian Navy service in 2016.
Design.
The ships have a steel hull and were originally designed to lay controlled minefields, though they would later be used as support vessels. The ships were initially propelled by two 800 horsepower Frichs diesel engines with two adjustable propellers. They were later replaced with two MTU diesel engines, providing 1600 kW of power in total. The ships were initially armed with two Oerlikon 20 mm cannons - one fore and one aft. In 1985, another 20 mm cannon was added to the fore. In 1997, a pair of FIM-92 Stinger launchers were also added. The weapons were removed when they were sold to Estonia. Estonian Navy later equipped the ships with M2 Browning machine guns. They are also equipped with two I-band navigation radars, two cranes (one 2 tonne crane fore and one 2.8 tonne crane aft) and two boats. The ships have a large mine deck, sufficient for carrying 50-60 naval mines, but can also be used for diving support, training or command duties.
