Lockheed Martin recently completed its 300th Electro-Optical Targeting System (EOTS) for the F-35 Lightning II stealth fighter.

EOTS is an imaging sensor which allows the F-35 to identify, track and designate targets. The 300th EOTS was completed under the 10th Low-Rate-Initial Production (LRIP) contract, and each system was delivered on time or ahead of schedule.

“Completing the 300th EOTS is a testament to the growth of the program and our ability to produce a reliable and affordable system,” said Paul Lemmo, vice president of Fire Control/Special Operations Forces Contractor Logistics Support Services at Lockheed Martin Missiles and Fire Control. “More than 650 EOTS have been ordered to date, and we are committed to continuing to drive down the cost and increase performance to support the F-35.”

F-35 EOTS is the world’s first sensor to combine forward-looking infrared and infrared search and track functionality to provide F-35 pilots with precise air-to-air and air-to-ground targeting capability. The company say EOTS allows aircrews to identify areas of interest, perform reconnaissance and precisely deliver laser and GPS-guided weapons.

According to the Lockheed Martin website:

“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 fuselage with a durable sapphire window and is linked to the aircraft’s integrated central computer through a high-speed fiber-optic interface.

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. Lockheed Martin has delivered more than 250 systems for the F-35 Lightning II.

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.”

More than 240 F-35s have been built and delivered worldwide, and they have collectively flown more than 105,000 flight hours.
