About this converter
Typhoon runs 48,000 tons submerged, double Borei and Oscar II at 24,000 each. Ohio at 18,750, Vanguard at 15,900, Triomphant at 14,335, Akula at about 13,000, Jin at about 11,000, Seawolf at 9,100 and Astute at 7,800 for scale follow. Displacement here is submerged tons. Surfaced tons run lower per boat. Dive depths and hull lengths rank on separate submarine pages, so meters stay out here.
How to use it
Pick two submarines and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try Typhoon against Astute to see the six times gap. The bars below scale to Typhoon so Astute looks thin next to it. Switch the unit to thousands for short figures. Ratios are exact divisions of the submerged displacements.
Borei at 24,000 ranks above Ohio at 18,750 despite draft table quirks. Surfaced versus submerged splits rows since submerged runs higher. About stays in Jin and Akula estimates. Dive depths rank on submarine-dive-depths and lengths on submarine-lengths, so this page keeps displacement only. Figures follow naval specs.
FAQ
What is the largest submarine?
Typhoon at 48,000 tons submerged. Borei and Oscar II follow at 24,000.
Is this the same as dive depths?
No. Dive depths and hull lengths rank elsewhere. This page keeps displacement.
How big is Ohio class?
