HSwMS Fenris

HSwMS Fenris was a monitor that served with the Swedish Navy from 1872 to 1903. She was an experimental small coastal defense monitor and while not seen as a success, experience gained in her development was used in the later Sölve class of monitors. Despite being of the John Ericsson class, she was closest in design to HSwMS Garmer.

Design
Fenris was 31.1 metre long by 6.1 metre at her widest point, she displaced 260 tons, and had a crew of 25. She had a coal capacity of nine tons and her propulsion system generated 44 indicated horsepower, with one propeller and one funnel. She was armed with a single 15 in M/65 Dahlgren gun.

Armor
The thickness of the belt armor and the turret armor varied, from 2.5 to 5 in and 4 to 10.2 in, respectively. However the armor of the conning tower and deck were consistently armored at 8 in and 7 in, respectively.

History
Construction of Fenris began in the Norrköping shipyard of engineering company Motala Verkstad in 1871 and she began her service the following year.
