Sonars:

Combat sonar suite: not defined yet
Mine avoidance and navigation: Kongsberg SA9510S MkII. The Kongsberg SA9510S MkII Mine Avoidance and Navigation Sonar (MANS) detects mines, obstacles, and the seafloor in a wide swath ahead of a submarine. It generates early target warnings and alarms to allow crews time to perform avoidance maneuvers while simultaneously conducting submerged and bottom-mapping navigation

Optical sensors:

Hensoldt OMS 150 and OMS 300 optronics masts
The HENSOLDT OMS 150 and OMS 300 are advanced, non-hull-penetrating optronic masts designed for submarines. Together, they form a digitised "twin-mast" suite—with the OMS 150 acting as a multispectral search system and the OMS 300 serving as a stealth attack system

Hensoldt i360°OS panoramic surveillance system
Made by by HENSOLDT, it's an  advanced, fully digital panoramic surveillance and optronic system. Designed primarily for next-generation submarines and naval vessels (such as the Norwegian and German Type 212CD class), it replaces traditional rotating periscopes with continuous, hull-penetrating digital monitoring to vastly improve crew situational awareness and survivability.

Radar:

Electronic warfare and decoys: Indra Sistemas digital EW systems
Indra Sistemas supplies a state-of-the-art navigation radar for the Type 212CD submarines. It is a fully digitized, X band,  solid-state system featuring dual continuous-wave and pulse-wave capabilities. Designed with a high bandwidth and frequency agility, the radar ensures a low probability of interception (LPI) to keep the submarine undetected.

Armament
Up to 14 torpedoes, missiles and drones

Torpedoes:

6 × 533 mm (21.0 in) torpedo tubes
CHWT (Common Heavy Weight Torpedo), designated as the DM2A5, is a joint German-Norwegian 533mm torpedo developed by ThyssenKrupp Marine Systems (TKMS) and Atlas Elektronik. Designed for silent operation and extended range, it will serve as the primary armament for the Type 212CD submarines operated by the German and Norwegian navies.

Capable of speeds over 50 knots and a maximum firing range exceeding 50 km.The guidance system: uses advanced fiber-optic cables for real-time control and high-speed data transmission, paired with a digital conformal sonar array.

Propulsion: Powered by a modular, silver-zinc battery system that produces an exceptionally low acoustic signature, making it difficult to detect.

Missiles:

IDAS Anti-air / anti light vessel.: (IDAS means Interactive Defence and Attack System) for Submarines) is a medium-range missile currently being developed for the Type 209 and Type 212A submarine class. Under consideration :is the  NSM-SL 3SM Tyrfing

IDAS missile,

Communications fit:

As of July 2026, no public source has yet disclosed the communications suite for the 212CDs
