Description: The OEPS-27 is an electro-optical sighting system designed to search and track airborne targets following its infrared emissions. The OEPS-27 Infrared Search and Track System (IRST) connected to a pilot's helmet-mounted target designation system provides unmatched performance during close-range air-to-air engagements, also referred to as dogfight. This electro-optical system is also suitable for designation of ground targets based on infrared/heat emissions. In addition to the IRST capability, the EOPS rangefinding capability using a built-in laser.

Basically, an OEPS system consists of four items: infrared thermal sensor, helmet-mounted target designator, laser rangefinder and a computer. The OEPS-27 was designed for integration into the Soviet/Russian Su-27 aircraft family providing IRST capability day/night, at all altitudes and with intense enemy Electronic Counter Measures (ECM) in both modes, lookup and lookdown. It provides a coverage of -60 to +60 degrees in azimuth and -60 to +15 in elevation and weighs 174 kg.
