Zeiss Periscopes For Turkish Submarines

On 31 March 2011, a contact about the modernization of Ay class (Type 209/1200) submarines was signed between STM and Undersecretariat for Defence Industries. The contract covers the youngest two boats,  S-51 TCG Doğanay and S-352 TCG Dolunay .

My previous information about the new Zeiss periscopes, that will replace the existing Kollmorgen periscopes was wrong. I  wrote that the new periscopes would be either SERO 400 or OMS 100.

Zeiss’ SERO 250-A attack and SERO 250-S search periscopes were selected for this project, according to rpdefense.over-blog.com.

The attack periscope features an eyesafe laser rangefinder, an image intensifier and a TV camera for navigation and targeting. The search periscope is equipped with an IR camera for night sight capability, a TV camera and an ESM-EW/GPS antenna for observation and reconnaissance.
