A photonics mast aboard a Virginia-class submarine. A photonics mast (or optronics mast [1]) is a sensor on a submarine which functions similarly to a periscope without requiring a periscope tube, thus freeing design space during construction and limiting risks of water leakage in the event of damage.
L3 Technologies' (LLL) Micreo acquisition played a key role in winning the latest deal pertaining to the submarine photonics mast programs.
The current photonics masts have a visual appearance so different from ordinary periscopes that when the submarine is detected, it can be distinctly identified as a Virginia-class vessel. As a result, current photonic masts will be replaced with Low-Profile Photonics Masts (LPPM) which resemble traditional submarine periscopes more closely. [52]
The French entity, Thomson Sintra, brought in by Thomson-CSF, was the European leader in defence-related sonar systems and the world's second after Lockheed Martin Loral, with annual sales of 1.5 billion francs, split between submarine sonars (35%), anti-submarine warfare systems (27%), airborne sonars (18%) and mine warfare (15%).

USS Arthur W. Radford with the aft mast replaced by the proof-of-concept AEM/S. USS New Orleans with fore and aft AEM/S.. The US Navy's Advanced Enclosed Mast/Sensor (AEM/S) system fully integrates advanced materials, structures, and manufacturing technologies with sensor technology, electromagnetics, and signature reduction.
The DUBV 43C towed array sonar of La Motte-Picquet.. A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. [1] Trailing the hydrophones behind the vessel, on a cable that can be kilometers long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting ...
