The submarine is fitted with a non-hull-penetrating mast supplied by Carl Zeiss Optronics. The mast integrates an optronic sensor with a high-definition resolution colour TV camera and third generation thermal imager. The cameras are gyroscopically stabilised in elevation and azimuth.

The sensor assembly is installed in a retractable unit outside the pressure hull of the submarine. The observation and operation of the mast are controlled on a console. The optronics mast system contains fully automatic functions for very fast surveillance and observation so the period of mast exposure above the surface is extremely short.

The surface search radar operates at I-band. The sonar suite includes an Atlas Elektronik CSU 90 hull-mounted passive and active search-and-attack sonar and flank sonar arrays.
