The Trygg class was the third and last class of torpedo boats to be built for the Royal Norwegian Navy. The three Trygg ships were constructed from 1919 to 1921 at Moss Verft in Moss (Trygg) and Horten naval yard (Snøgg and Stegg).

Though much larger and better armed than its predecessors, the cigar-shaped 1. and 2. class torpedo boats, the Trygg class was far from modern when it was called upon during the Norwegian Campaign in 1940.

The class was named after its first ship, the Trygg - "trygg" is Norwegian for rugged, safe, stable, secure, dependable.^[2]
