In 1992, she was purchased for the Royal Swedish Navy, renamed to Belos, and has since been redesigned into an advanced diving and submarine rescue ship.

Onboard Belos, an extensive array of remotely operated underwater vehicles (ROVs), oceanographic equipment, craneage, diving-, medical-, and decompression facilities are accessible.

Different sonar systems attached to the hull and towed astern of the Belos can be used for searching distressed submarines or other objects at the seabed.

For smaller submarines or crewed submersibles, the rescue operation may be cutting free the vessel itself if it is snagged by e.g. nets or cables and unable to surface (see AS-28).

The divers are equipped with hot-water suits, TV cameras, and constant communication with the diving supervisor on board the Belos.

The maximum diving depth is 1,000 metres (3,300 ft) and underwater work is performed by using hydraulic manipulators with a range of interchangeable tools.

Initially, the 100-ton crane was used for launching and recovering URF, a method rather unreliable during rough weather, leading to the construction and installation of a 55 ton A-frame aft.
