F-35 JSF Distributed Aperture System (EO DAS)

Courtesy: Northrop GrummanNorthrop Grumman has developed the only 360 degree, spherical situational awareness system in the electro-optical distributed aperture system (DAS). The DAS surrounds the aircraft with a protective sphere of situational awareness. It warns the pilot of incoming aircraft and missile threats as well as providing day/night vision, fire control capability and precision tracking of wingmen/friendly aircraft for tactical maneuvering.Designated the AN/AAQ-37, and comprising six electro-optical sensors, the full EO DAS will enhance the F-35's survivability and operational effectiveness by warning the pilot of incoming aircraft and missile threats, providing day/night vision and supporting the navigation function of the F-35's forward-looking infrared sensor.The DAS provides: * Missile detection and tracking * Launch point detection * Situational awareness IRST & cueing * Weapons support * Day/night navigationIn addition to developing the EO DAS, Northrop Grumman Electronic Systems is supplying the F-35's AN/APG-81 advanced electronically scanned array (AESA) fire-control radar. The AESA radar is designed to enable the pilot to effectively engage air and ground targets at long range, while also providing outstanding situational awareness.
