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.
The Trygg class had a fairly substantial armament for being small ships of relatively early design. Each carried two 76 mm main guns, an Oerlikon 20mm for anti-aircraft defence, as well as two twin 45 cm torpedo tubes. Combined with a reasonable speed of 25 knots (46 km/h) and excellent manoeuvrability this enabled the Trygg class vessels to operate effectively both in cooperation with other naval units and on their own. Their operations were however limited mostly to coastal waters as they were not very seaworthy or stable platforms, having been constructed for operations close to land. In the fighting that followed the German invasion on 9 April 1940 the Trygg class would see first line action as these ships were often all that was available to the Norwegian forces.
In 1932, the Norwegian Labour Party made public a proposal crafted by Fredrik Monsen, that the armed forces be dissolved entirely and replaced by a "civil guard". The civil guard would include 18 Trygg class vessels, with the armament of two 76 mm main guns and two twin 45 cm torpedo tubes retained.Olaf Kullmann and Erik Anker Steen had contributed to the "civil guard" concept with advice from a naval perspective.
