The low-drag, stealthy Electro-Optical Targeting System is integrated into the F-35 Lightning II’s fuselage with a durable sapphire window.
According to the interesting video in this post, the Electro-Optical Targeting System (EOTS) for the F-35 Lightning II is an affordable, high-performance, lightweight, multi-function system that provides precision air-to-air and air-to-surface targeting capability.
The low-drag, stealthy EOTS is integrated into the F-35 Lightning II’s fuselage with a durable sapphire window and is linked to the aircraft’s integrated central computer through a high-speed fiber-optic interface. The Distributed Aperture System (DAS) Window Panel consists of six low-observable, infrared transparent windows for Electro-Optical (EO) DAS sensors on the F-35. Each shipset of windows enables the EODAS sensor to provide threat detection and 360-degree situational awareness to the pilot.
As the first sensor to combine forward-looking infrared and infrared search and track functionality, EOTS enhances F-35 pilots’ situational awareness and allows aircrews to identify areas of interest, perform reconnaissance and precisely deliver laser and GPS-guided weapons.
Advanced EOTS, an evolutionary electro-optical targeting system, is available for the F-35’s Block 4 development. Designed to replace EOTS, 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 F-35 pilots’ recognition and detection ranges, enabling greater overall targeting performance. 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.
Of note, Advanced EOTS will provide more than $1 billion in life cycle cost savings.
