“Voyage North” is a color film that focuses on operations on the HMS Artemis (S49), an Amphion class submarine built in 1946 during a voyage. The official British government film, produced circa 1970, is an impressionistic account of life on the submarine told partly through the eyes of Lt. Ellison, a new submarine officer. After seeing the sub while pulling into a dock in Copenhagen, Denmark, we move inside at mark 02:24 for a training exercise on escape routes in the event of an emergency. As the film moves along we see classroom instruction and additional onboard training, with Ellison coming aboard at mark 06:30. Setting course for a survey mission north of Iceland, Ellison is shown standing watch at mark 08:30 as the crew topside critique their new shipmate at mark 09:53. A series of scenes from the sub follow as the camera captures day-to-day operations before the vessel approaches an ice flow at mark 13:50 and the disembark for an award ceremony, a group photo, and winter sports including snowball fights, sledding, and ice fishing. Artemis leaves the frozen north starting at mark 16:16 and we return to more routine scenes before the vessel returns to Copenhagen.

HMS Artemis (P449) was an Amphion-class submarine of the Royal Navy, built by Scotts Shipbuilding & Engineering Co. of Greenock and launched 28 August 1946. On 1 July 1971 Artemis sank in 9 metres (30 ft) of water while moored at the shore establishment HMS Dolphin at Gosport during refueling. Because the crew had negligently run cables through the hatches which were left open, the submarine began to fill with water and subsequently sank at her moorings. Three men were trapped inside but rescued. She was raised on 6 July and decommissioned, sold to be broken up for scrap on 12 December 1971.
