HNoMS Brage was a Vale-class Rendel gunboat built for the Royal Norwegian Navy at Horten Naval Yard in 1874, with build number 58. She was one of a class of five gunboats - the other ships in the class were Vale, Nor, Uller and Vidar. Brage was, in addition to the heavy, muzzle-loading main gun, armed with a small 'Quick Fire' gun and a 37mm Hotchkiss Revolving Cannon (broadly similar to the Gatling gun).
