The F-35 features internal and external weapon stations, the use of which directly affects the stealth signature [27].
Starting from Lot 15, the Sidekick adapter enables internal carriage of 6 instead of 4 AIM-120 AMRAAM in the F-35A/C variants [28]. The adapter is not compatible with the F-35B.
6 external stations (3 per wing) with a total payload capacity of up to 8,160 kg (18,000 lbs) [27]. The use of external pylons significantly increases the radar cross-section.
Maximum external loading while sacrificing stealth characteristics. Typical for scenarios with established air superiority.
