Physical

Dimensions, weight and crew.

Length Overall length including gun/probe where applicable.: 60.4 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.: 685 t
Max speed Top speed in knots (surfaced, for submarines). Higher aids positioning and screening.: 30 kn

Stronger than 74% of warships
Range Cruising range in nautical miles. Nuclear vessels are effectively unlimited (fuel-wise). Higher means more reach without replenishment.: 2,000 nmi

Bottom 1% of warships
Complement Crew size. Fewer eases manning cost; more may indicate a larger, more capable platform.: 41
Propulsion plant Machinery type — nuclear reactor, gas turbine (COGAG), CODAG, diesel-electric, AIP.: CODAG (2× diesel + 2× gas turbine, waterjets)

Sensors & avionics

Radar, sensor suite and datalinks.

Radar Primary radar. AESA (active electronically scanned array) is the current state of the art.: MSTAR active phased-array radar

Program

Cost, production scale and operators.

Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability.: 3

Stronger than 41% of warships
Operator countries Number of countries operating the system. More operators means broader support ecosystem.: 1

Stronger than 45% of warships
