Sirius was owned by Bergenske Dampskipselskap and was in the time from July 1894 to July 1895 charted by the Coastal Express together with Olaf Kyrre. She had cabins for seventy passengers, and in the following years she sailed several routes along the Norwegian coast. In 1927  the company had got themselves several better ships with more comfort for the passengers so they decided to remove the cabins, and for the rest of her career Sirius sailed between Oslo and Finnmark as a cargo freighter. On 18. May 1940 Sirius is on a journey from Røsneshavn to Risøyhavn with a crew of eighteen men. They have earlier delivered a cargo of hay at Risøyhavn, when they in Solbergfjorden is spotted by a German airplane which attacks her. With machine-guns the airplane dives towards Sirius and opens fire, and the crew on board suffers several  injuries already in the first assault. Again the German airplane attacks, and this time Sirius receives seven bombs, and soon after she breaks in two pieces and sink within a few minutes. Only eleven men of the crew survives this attack. Today the wreck of Sirius rest on the north side of Dyrøy on a depth of forty five to seventy meters in a relatively good condition. Around the bridge there are a heavy damaged area after the attack, but the hull in itself is mostly intact. You need a boat to visit the wreck of Sirius...
