Optronic Imaging, Surface Ship and Submarine Imaging and Communications

L3Harris is the world’s largest provider of submarine imaging systems, delivering precise, high-resolution optics and integrated sensor packages. From the first submarine periscope to today’s advanced optronic sensors, L3Harris continues to develop systems that enable operators to observe, identify and control integrated imaging capabilities in the most demanding maritime environments.”

Our submarine optronic systems include precise, high-resolution electronic imaging capabilities featuring VIS, SWIR, MWIR and low-light sensors, along with integrated sensor packaging. These integrated solutions can incorporate ESM/EW, DF, GPS and communications antennas, as well as low observable technologies.

L3Harris also provides the next-generation Low Profile Photonics Mast for advanced submarine imaging systems supporting the U.S. Navy.

In addition, the company designs and manufactures the Universal Modular Mast, selected as the common above-water sensor platform for U.S. and international submarines.

Beyond optronic systems, L3Harris designs and manufactures a range of submarine mast and valve technologies, including snorkel masts, hull induction valves, gas exhaust valves and seawater hull valves.
