Bofors 105 mm Coastal Automatic Gun L/54 (full English product name: Bofors 105 mm Automatic Gun L/54 In Turret For Coastal Defence), was a Swedish fully automatic dual purpose gun turret system for coastal defence designed by Bofors around the turn of the decade 1950 for use in the Swedish Coastal Artillery and for export. It was the first modern weapon system designed for the Swedish Coastal Artillery and was designed to be embedded in concrete or granite mixes for camouflage and protection.
Development started in the late 1940s, and the construction of 6 gun installations based on this system was offered by Bofors in 1950. Various problems plagued the design and construction process and the last gun installation was not finished and ready for operational use until 1968, 12 years behind schedule.
