Optronic Imaging, Naval Undersea Imaging and Communications

L3Harris is the world’s largest submarine imaging system provider. Delivering precise, high-resolution optics, and integrated sensor packages. From the first submarine periscope to the latest optronic sensors, L3Harris continues to produce systems that enable users to look, see, and control the integrated imaging systems.

L3Harris submarine optronic systems include precise, high-resolution electronic imaging VIS, SWIR, MWIR, low light sensors and integrated sensor packaging. Integrated sensors can include ESM EW, DF, GPS or communication antennas, and low observables technology.

L3Harris provides the next generation Low Profile Photonics Mast on the next generation submarine imaging systems to the U.S. Navy.

We also design and produce the Universal Modular Mast which was chosen as the common equipment for above water sensors on U.S. and international submarines.

L3Harris also designs and manufactures submarine masts, including snorkel masts, as well as hull induction valves, gas exhaust valves and seawater hull valves.
