The "Kingston" class is equipped with a Kelvin Hughes navigational radar using the I band and a Kelvin Hughes 6000 surface search radar scanning the E and F bands. The vessels carry an AN/SQS-511 towed side scan sonar for minesweeping and a Remote-control Mine Hunting System (RMHS). The vessels are equipped with one Bofors 40 mm/60 calibre Mk 5C gun and two M2 machine guns. The 40 mm gun was declared obsolete and removed from the vessels in 2014. Some of them ended up as museum pieces and on display at naval reserve installations across Canada. The "Kingston"-class coastal defence vessels have a complement of 37.
