HNoMS Thrudvang

HNoMS Thrudvang was a monitor built for the Royal Norwegian Navy in 1869. She was scrapped in 1918, well after her muzzle-loading guns were outdated. The slightly later HNOMS Thor can be seen as an improvement of the Skorpionen class.

Details
Thrudvang was armed with two heavy rifled muzzle-loaders in a revolving turret. She had five inches of iron armour on her deck, and her turret was protected by twelve inches of iron armour.
