Full specifications

Firepower

Armament, payload and guidance.

Torpedo tubes Number of torpedo tubes (submarines and some surface ships).: 8

Stronger than 88% of submarines

Physical

Dimensions, weight and crew.

Length Overall length including gun/probe where applicable.: 68 m

Naval

Displacement, speed, endurance and diving depth.

Displacement Standard displacement in tonnes — the ship’s size class. Larger hulls carry more but cost more and are less agile.: 1,850 t
Submerged speed Maximum speed while submerged (submarines). Higher is faster underwater.: 20 kn

Stronger than 29% of submarines
Range Cruising range in nautical miles. Nuclear vessels are effectively unlimited (fuel-wise). Higher means more reach without replenishment.: 15,000 nmi

Top 6% of submarines
Test depth Maximum rated diving depth (submarines). Deeper is harder to detect and engage. Actual crush depth is classified.: 400 m

Stronger than 76% of submarines
Complement Crew size. Fewer eases manning cost; more may indicate a larger, more capable platform.: 33
Propulsion plant Machinery type — nuclear reactor, gas turbine (COGAG), CODAG, diesel-electric, AIP.: Diesel-electric with fuel-cell air-independent propulsion

Program

Cost, production scale and operators.

Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability.: 1

Bottom 9% of submarines
Operator countries Number of countries operating the system. More operators means broader support ecosystem.: 1

Stronger than 39% of submarines
