Advanced EOTS
The Advanced EOTS is a further evolution of the EOTS electro-optical targeting system intended for the F-35 Block 4 stealth fighter. Advanced EOTS incorporates a wide range of enhancements and upgrades, including short-wave infrared, high-definition television, an infrared marker and improved image detector resolution. These enhancements increase the F-35s recognition and detection ranges, enabling greater overall targeting performance. Lockheed Martin announced the Advanced EOTS in September 2015.
Advanced EOTS includes a larger aperture and provides pilots with multi-spectral sensing options such as high-resolution Mid-Wave IR, Short-Wave IR and Near IR. Utilizing the same volume and weight, Advanced EOTS is effortless to integrate into the F-35 Lightning II with the "plug and play" feature.

Additionally, because of increased reliability and reduced costs per operating hour, Advanced EOTS is expected to provide more than $1 billion in life cycle cost savings for users.
"We understand the importance of providing pilots with the most advanced technologies available today," said Michael Williamson, vice president of Sensors & Global Sustainment at Lockheed Martin Missiles and Fire Control.
Lockheed Martin is prepared to integrate Advanced EOTS on the F-35 should customers require the upgrade as part of F-35 follow on modernization. Advanced EOTS was funded through internal investment and was vetted through Operational Analysis against the most demanding F-35 missions. It provides enhanced performance for both air-to-air and air-to ground day and night missions.
With Advanced EOTS, customers get significantly expanded capabilities, greatly increased performance, higher reliability and sizable sustainment savings.
