Diagnostic Engine Starting System Controller (DESSCׁׂׂׂ)

The DESSC (Diagnostic Engine Starting System Controller) is an all digital replacement for the original Engine Starting System (ESS) controller of the F-16 aircraft providing an improved Jet Fuel Starter (JFS) control logic and powerful diagnostic capabilities.

The DESSC significantly improves the engine starting system performance and reliability while increasing flight safety and availability, with the additional benefit of reducing the ESS maintenance efforts and costs.

The DESSC is a mature and proven solution, which is in operational service onboard more than 1,500 F-16 aircraft operated by several Air Forces worldwide, including the USAF, and is fully qualified by Lockheed Martin and USAF (NSN 2925436-7325YP).
