Electro-Optical Sight Systems, Naval Surface Imaging


L3Harris’ Electro-Optical Sensor Systems (EOSSs) have enabled successful mission execution for over 20 years, possessing unique features and capabilities best suited for Naval Gun Weapon System (GWS) targeting, surveillance, and situational awareness. Our current generation MK20 Mod 1 is a single, affordable, multi-purpose EO/IR solution that is designed from the ground up to provide superior operation and surveillance in a light-weight and lower cost package - supporting both Grade A and Grade B shock requirements.

The scalable modular open systems architecture of the MK20 Mod 1 offers a standard interface with bandwidth reserve between director and modules and facilitates mission configurable sensors.

The MK20 Mod 1 has three primary functions - EOSS/GWS integration, automatic target detection and tracking, and day/night video surveillance. These functions effectively support multiple mission requirements for full-spectrum surface detection, identification, surveillance, and target assessment. The MK20 Mod 1 supports operations including anti-surface and anti-air warfare, spotting and damage assessment, target detection and identification, naval gun fire support, safety check-sight, location/track of man overboard, and channel position and navigation. 

L3Harris' MK20 Mod 1, and similar international configurations are platform and weapon system agnostic, designed for integration with customer-selected or L3Harris-built fire control, consoles, and ship systems – significantly reducing ship change costs, meeting individual platform shock requirements, and improving overall performance. These Electro Optical Sighting Systems leverage L3Harris’ expertise to offer a new generation system.
