A New ‘Kill Web’ Could Change Air Combat

The most quoted stealth statistics in modern airpower journalism are not measurements at all — they are unclassified estimates built from physics models, retired-general anecdotes, and industry hints, stacked around a genuinely exceptional airframe that the Air Force itself has never fully priced out in public.

Key Points

The Air Force’s own fact sheet confirms the F-22 Raptor as a “mach two class” aircraft with supercruise and a ceiling above 50,000 feet — official, but deliberately imprecise on exact top speed.
The oft-cited radar cross-section of roughly 0.0001 square meters (a “steel marble”) comes from a 2009 Lockheed Martin disclosure and subsequent modeling, not from a declassified government measurement.
Comparisons claiming the F-22 is 15 times stealthier than the F-35 and 100 times stealthier than the J-20 are mathematically consistent with commonly cited open-source RCS ranges, but those ranges themselves span an order of magnitude or more.
A 2025 Air University study complicates the simple stealth hierarchy: it credits the J-20’s radar with a longer detection range than the F-35’s, suggesting China may be compensating for weaker stealth with more aggressive sensor power.
Radar cross-section is not a fixed number — it swings by 40 to 60 decibels depending on aspect angle and frequency band, meaning any single figure describes one geometry against one radar, not the aircraft as a whole.

What the Air Force Actually Confirms, and What It Doesn’t

Strip away the enthusiast-site superlatives and the government’s own paper trail is comparatively modest. The Air Force fact sheet for the F-22 Raptor lists “speed: mach two class with supercruise capability,” a ferry range past 1,850 miles with external tanks, and a service ceiling above 50,000 feet. It does not publish Mach 2.25 as an official maximum, nor does it disclose a radar cross-section figure of any kind. Both numbers — the widely repeated top speed and the “smaller than a marble” signature — trace back to secondary sources: aviation trade press, a 2009 Lockheed Martin briefing, and derivative reporting that has been recycled for over a decade until it reads as settled fact.

That doesn’t make the numbers wrong. Lockheed Martin’s 2009 figure of roughly 0.0001 square meters, or −40 dBsm, has held up as the reference point across independent aviation literature for fifteen years. But precision claimed to four decimal places about a classified program should be read as an informed approximation, not a spec sheet entry — a distinction that matters enormously once that number gets multiplied against other aircraft’s estimates to produce headline ratios.

The Mechanics of a Marble-Sized Signature

Radar cross-section measures how much of a transmitted radar pulse bounces back to the receiver, expressed in square meters of an idealized flat reflector — hence the folk comparisons to marbles, golf balls, and barn doors. The F-22 achieves its extraordinarily low figure through faceted fuselage shaping that deflects energy away from the emitter, internal weapons carriage that eliminates hard-point reflections, radar-absorbent coatings, and serrated panel edges that scatter rather than reflect. Supercruise — sustained supersonic flight without afterburner, reportedly around Mach 1.8 — is enabled by the Pratt & Whitney F119 engine’s dry thrust, a capability that keeps the aircraft both fast and fuel-efficient without lighting the afterburner plume that would otherwise announce its presence on infrared sensors.

The F-35, despite sharing Lockheed Martin’s design lineage, trades some frontal stealth for multirole versatility and a broader mission set; its RCS is commonly estimated near 0.0015 square meters, the “golf ball” to the Raptor’s marble. The ratio between those two figures — roughly fifteen to one — is the arithmetic basis for the F-22’s stealth premium over its stablemate, and it is one of the more consistently repeated comparisons in the literature.

Where the J-20 Comparison Gets Shakier

The claim that the F-22 is a hundred times stealthier than China’s Chengdu J-20 requires picking a specific point within a very wide estimate band. Open-source assessments of the J-20’s radar cross-section range from roughly 0.01 to 0.3 square meters depending on the modeler and the assumed radar band. Divide the F-22’s 0.0001 estimate into the low end of that range and you get roughly a hundredfold advantage; divide it into the high end and the multiple balloons past a thousand. Neither number is a lie, exactly — both are defensible extrapolations from publicly available physical-optics modeling — but treating either as a settled fact overstates the confidence anyone outside a classified test chamber can actually claim.

The J-20’s canard-delta configuration and larger frontal area give it inherently different scattering behavior than the F-22’s more purely faceted design, and Chinese state media has never conceded a specific RCS figure, leaving Western analysts to reverse-engineer estimates from photographs, radar cross-section theory, and comparisons to earlier low-observable designs like the F-117.

The Counter-Argument: Sensor Power Over Shape

The most substantive challenge to the “F-22 as unambiguous benchmark” narrative doesn’t dispute its stealth shaping at all — it questions whether shaping is still the whole game. A 2025 Air University analysis of the J-20’s active electronically scanned array radar concluded that the Chinese jet’s radar can reportedly detect targets out to 120 miles, versus roughly 80 miles for the F-35’s system, even though the F-22’s own APG-77 array, with as many as 1,900 transmit-receive modules, still outranges the F-35 by about a third. That is a genuinely documented, named-source claim, not idle speculation, and it points to an uncomfortable trade-off: China may be accepting a larger radar signature in exchange for a radar that sees farther first. In modern beyond-visual-range combat, detection range and weapons reach can matter as much as how small your own blip looks.

What the Numbers Actually Mean for Air Dominance

None of this diminishes the F-22 as an airframe. Its combination of supercruise, altitude performance, and shaping-driven low observability, achieved with 1990s-era design tools and locked into a production run of only 187 aircraft before Congress halted the line in 2009 over its roughly $350 million per-unit cost, remains a genuine engineering benchmark two decades after entering service. But the discipline worth carrying forward is treating every RCS ratio in circulation — 15-to-1 against the F-35, 100-to-1 against the J-20 — as an informed estimate riding on classified foundations, not a verified fact. The real strategic picture, as the sensor-range debate shows, is less about whose jet is smallest on radar and more about who detects, decides, and fires first.
