Full specifications

Firepower

Armament, payload and guidance.

Firepower specifications
Torpedo tubes Number of torpedo tubes (submarines and some surface ships).	8 Stronger than 89% of submarines

Physical

Dimensions, weight and crew.

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

Naval

Displacement, speed, endurance and diving depth.

Naval specifications
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 27% 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 4% 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 71% 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.

Program specifications
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
