: Newer Block III variants introduced options for enclosed weapon pods to carry external stores without the massive RCS penalty typically caused by hanging bombs and missiles on external pylons. Comparative Performance In a "clean" configuration (no external stores), the Super Hornet's RCS is comparable to some 5th-generation concepts, though it remains significantly larger than the F-35.

These external weapons lack stealth geometry. Cylindrical missile bodies, rounded bomb noses, and right-angled pylon attachments scatter radar waves aggressively. Loading a Super Hornet with a standard combat payload can degrade its RCS back up to f18 rcs
The Super Hornet achieved its reduced RCS through a combination of structural reshaping and radar-absorbent materials (RAM).
When Boeing redesigned the Hornet into the F/A-18E/F Super Hornet in the 1990s, reducing the aircraft's RCS was a primary structural directive. Though it is a "4.5-generation" fighter rather than a true stealth aircraft, the Super Hornet incorporates extensive low-observable engineering. 1. Geometric Alignment (Planform Shaping) A standard legacy fighter jet typically has an
The legacy Hornet features a conventional design with twin vertical stabilizers, straight-edged wings, and external boundary-layer diverter slots for the engine inlets. These sharp perpendicular angles act as excellent radar reflectors, bouncing electromagnetic energy straight back to an enemy receiver. The Inlet and Engine Face Problem
The original F/A-18A-D Hornets were designed in the 1970s with aerodynamics as the primary driver. While small, they were aerodynamically "dirty" from a radar perspective, full of radar-reflecting right angles and protruding ordinance. Though it is a "4
However, critics often point out that the Super Hornet still has a significant RCS compared to the F-22 or F-35. The "bunny ears" twin vertical tails, while canted outward to reduce side-aspect signature, still present a radar target. Additionally, the Rhino’s sheer size—much larger than its predecessor—naturally increases its reflectivity.
Standard external fuel tanks hung under the wings are massive radar targets. Block III introduced Conformal Fuel Tanks that sit tightly on top of the upper fuselage shoulders. These tanks conform to the aerodynamic and stealth lines of the jet, adding fuel capacity with virtually zero penalty to the aircraft's RCS. Enclosed Weapons Pod (EWP)
External stores dramatically increase RCS:
