OVERVIEW: Photonics Masts are advanced submarine sensor systems replacing traditional optical periscopes, integrating low-light TV (LLTV), infrared (IR), and electro-optical (EO) cameras. They provide enhanced visual reconnaissance with improved stealth and data versatility.

GENERAL DESCRIPTION: Photonics Masts combine LLTV, IR, and EO sensors mounted on a retractable mast to deliver high-resolution imaging above the waterline without requiring a traditional periscope tube. This design enhances stealth by eliminating the need for a direct optical path through the hull. The system provides real-time video feeds for navigation, targeting, and surveillance, usable day and night in various weather conditions. Photonics masts support digital image processing, target tracking, and can interface with other onboard combat and navigation systems. Their modular sensor suite allows simultaneous multi-spectral observation, increasing situational awareness for submarine crews.

ROLE SUMMARY:
