Sensor fusion is the heart of the F-35 and its most important differentiator compared to fourth-generation fighter aircraft [34].
All sensor data – radar (APG-81), infrared (DAS, EOTS), electronic intelligence (ASQ-239), and data links (MADL, Link-16) – are correlated in a central fusion engine and merged into a unified tactical situational picture [34].
The 50x20 cm touchscreen display (20x8 inches) replaces conventional individual instruments and shows the fused situational picture in configurable views [35].
Developed by Collins Aerospace (RTX) and Elbit Systems, the Gen III helmet enables [36]:
The F-35 does not operate primarily as a kinematic weapon platform but as a sensor node in a networked "Kill Web" [37]. The ability to absorb, process, and distribute information is operationally more significant than speed or maneuverability alone.
