Lifecycle cost (est.)

$3.0B – $4.2B

Acquisition is only ~30% of lifecycle cost, operating & support dominate over ~35 yrs. Rough 2.5–3.5× the unit price. How we estimate this →

Interoperability

No standardised NATO calibre / datalink detected in public specs.

Derived guidance from public data, export regime by country of origin, lifecycle from the GAO ~30% acquisition rule. Verify eligibility, pricing and offsets with the manufacturer and your acquisition authority.

Full specifications

Physical

Dimensions, weight and crew.

Physical specifications
Length Overall length including gun/probe where applicable.	245 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.	33,000 t
Full-load displacement Displacement fully loaded with fuel, stores and munitions.	38,000 t
Max speed Top speed in knots (surfaced, for submarines). Higher aids positioning and screening.	25 kn Stronger than 16% of warships
Range Cruising range in nautical miles. Nuclear vessels are effectively unlimited (fuel-wise). Higher means more reach without replenishment.	7,500 nmi Stronger than 73% of warships
Complement Crew size. Fewer eases manning cost; more may indicate a larger, more capable platform.	450
Aircraft carried Embarked aircraft/helicopters. Higher extends the ship’s sensor and strike reach.	15 Stronger than 71% of warships
Propulsion plant Machinery type, nuclear reactor, gas turbine (COGAG), CODAG, diesel-electric, AIP.	CODLAG: 2× gas turbines + diesel generators

Sensors & avionics

Radar, sensor suite and datalinks.

Sensors & avionics specifications
Radar Primary radar. AESA (active electronically scanned array) is the current state of the art.	Kronos multifunction AESA radar

Program

Cost, production scale and operators.

Program specifications
Unit cost Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper.	$1,200,000,000 Stronger than 46% of warships
Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability.	1 Stronger than 16% of warships
Operator countries Number of countries operating the system. More operators means broader support ecosystem.	1 Stronger than 45% of warships
