Bofors 120 mm Automatic Gun L/46,[4] most commonly referred to as either Bofors FAK 120 or Bofors TAK 120 depending on the configuration (field gun vs naval gun), was a Swedish liquid-cooled single-barreled 120 mm (4.7 in) caliber long-range anti-aircraft autocannon designed by Bofors during the 1950s for indigenous use and export.[2][4]
It was produced in two different variants during the 1950s and 1960s respectively, a field variant[4] and a naval variant,[1] and the latter still being in service today with the Indonesian Navy.[1]
