The MK 20 EOSS (Electro-Optical Sensor Systems) Mod 1 is employed by the U.S. Navy DDG 51 Arleigh Burke-Class guided missile destroyers, CG 47 Ticonderoga-class guided missile cruiser, and the Coast Guard offshore patrol cutters.

L3 Harris 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.
