Bofors 57 mm gun

The Bofors 57 mm guns are a series of dual-purpose naval guns designed and produced by Bofors Defence (now a part of BAE Systems).

Design

The Bofors gun has a 120-round magazine and a rate of fire of about 220 shots/minute. The rate of fire and the ability to change ammunition types quickly makes the gun suitable for engaging both aerial and naval targets. Normally a computer aims the gun, giving it high accuracy. However, the crew can also train and aim the gun using instrument panels that are either on or in direct contact with the gun.

Deployments

The Swedish Navy is the primary user of the gun and Bofors Defence has exported it for use by navies of Brunei, Canada, Croatia, Finland, Indonesia, Malaysia, Mexico, Netherlands, Singapore and Thailand.

The Mk 3 version with stealth turret housing will enter US naval service as the Mk 110 57 mm gun.
