The Bofors 57 mm Naval Automatic Gun L/70, among other names, is a series of dual-purpose naval guns designed and produced by the Swedish arms manufacturer AB Bofors, designed in the late 1960s as a replacement design for the twin barreled Bofors 57 mm Naval Automatic Gun L/60. The gun is remotely controlled by a fire-control computer but can as a redundancy measure also be operated manually by crew using instrument panels either on or in direct contact with the gun.
