Key RCS Reduction Features
Serrated Panels and Edge Alignment:
The design incorporates serrations on panel joints and alignment of edges to minimize gaps and cavities that reflect radar waves.
S-Shaped Intakes:
These curved ducts hide the rotating fan blades from radar, a significant source of reflection.
Internal Radar Blocker:
A radar blocker is positioned inside the intake to prevent radar waves from reaching the fan blades.
Canted Vertical Stabilizers:
The angled stabilizers avoid creating 90-degree angles that act as strong radar reflectors.
Enclosed Weapons Pods (EWPs):
Block III Super Hornets use EWPs to carry external weapons, greatly reducing their radar signature by housing them internally.
Radar Absorbing Materials (RAM):
Special coatings are applied to specific areas for certain missions, further reducing the aircraft's radar signature.
How RCS is Affected
External Stores:
Carrying external fuel tanks, weapons, and pods dramatically increases the RCS, making the aircraft much more detectable.
Configuration Dependent:
The exact RCS of the Super Hornet varies greatly depending on its configuration. A "clean" configuration (no external stores) will have a much lower RCS than a combat-loaded aircraft.
Block III Upgrades:
The latest Block III version of the Super Hornet boasts the most significant RCS reductions, with claims of up to a 50% reduction in frontal RCS thanks to features like the EWP.
