TheBrinio class (sometimes referred to asGruno class) was a class of threegunboats built by theRijkswerf in Amsterdam for theRoyal Netherlands Navy. The class comprisedGruno,Brinio andFriso.^[1]

All ships were still in service at the start of World War II. While considered obsolete due to their age and lack of proper anti-aircraft weaponry, these ships could still provide effective firepower for their size due to the large main battery.^[2]

Friso was sunk by German bombers on 12 May 1940 on the IJsselmeer andBrinio was scuttled by her own crew on the IJsselmeer on 14 May 1940 after being damaged by a German aircraft.

Gruno escaped to the United Kingdom where she was equipped with depth charges and an asdic type 140A sonar in January of 1941. She continued to serve in the defense of British home waters until May of 1944 when she was laid up and used as an accommodation ship for the remainder of the war in Europe. She then returned to the Netherlands where she served as an accommodation ship once more until sticken in 1950.Gruno was sold for scrap in 1959.^[2]
