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 She was scrapped in 1918, well after her muzzle-loading guns were outdated.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 Thor can be seen as an improvement of the Skorpionen class.

Details

The crew of Thrudvang photographed on 13 June 1870, gathered around the central turret. Note ventilator on left side.

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.
