The Israeli air force is finalising plans for the first-ever comprehensive upgrade of its Boeing F-15 C/Ds. The front-line fighters have been in service since 1976. Some airframe strengthening and replacement of some of the wiring and hydraulics and the air conditioning system should extend the aircrafts' service lives by at least 10 years. The upgrade will also include new avionics and displays, and a health-monitoring system to ease maintenance.
