HNoMS Ellida was a 1. class gunboat built for the Royal Norwegian Navy.
Like the other Norwegian gunships of her era, she carried a reasonable heavy armament on a diminutive hull.
A distinct feature of Ellida was that her funnel could be raised and lowered as needed.
It is unclear from the sources if the listed armament is the original armament, or if Ellida originally was armed with a much heavier main gun like the slightly older 1. class gunboat Sleipner.
In 1914 Ellida was refitted once more, and became the mother ship and support vessel for the early Norwegian submarines (the A class).
