Viking’s Submarine-Equipped Polar Expedition Ship

Viking Octantis launched in 2022 as the near-sister ship to Viking Polaris, and together they form Viking’s purpose-built polar expedition fleet. Both ships share the same 378-guest capacity, 189 all-balcony staterooms, PC6 polar class, Science Lab, and Viking’s signature no-casino, curiosity-first culture. The critical difference: Viking Octantis carries two custom-built submarines.

The submarines are designed for passenger use and allow guests to descend beneath the polar surface in complete safety. In Antarctica, this means experiencing the underwater world of the Southern Ocean: bioluminescent life, the submerged portions of icebergs, and the marine ecosystem beneath the ice edge that most Antarctic travelers never see. It’s a genuinely differentiated experience that makes Octantis the more compelling choice of the two when both are available on the same itinerary.

The broader Viking expedition model applies equally to both ships: no children under 18, intellectually curated programming, citizen science through the Science Lab, and a guest demographic of experienced global travelers. For those who have sailed Viking’s river or ocean products and now want Antarctica, Octantis combines the familiar Viking atmosphere with expedition access that surpasses many pure expedition vessels on the specific dimension of what happens beneath the surface.
