Too hot for stealth?
F-35 Got Hit
Heat-Seeker Nails $100M F‑35 — Is Stealth Over or Overhyped
TLDR: An Iranian heat‑seeking missile reportedly hit an F‑35, which landed safely as Iran claims a kill and the U.S. investigates. Commenters split between “old tech and expected tradeoffs” and “stealth’s in trouble,” with side debates on China’s sensors, exhaust designs, and how many shots it took.
A reported Iranian heat‑seeking missile tagged an F‑35 near Iran, forcing an emergency landing. Pilot’s fine, Iran’s Revolutionary Guard claims a kill, and the U.S. says it’s investigating. The article’s big point: stealth hides you from radar, not from heat, and a passive heat‑tracker doesn’t announce itself. Cue comment‑section meltdown.
One camp rolled its eyes hard: “we’ve had heat‑seekers forever” and flares exist — with links to the 1950s AIM‑4 Falcon. Another camp shouted wake‑up call, arguing modern seekers are smarter, flares fool less, and the F‑35 doesn’t carry a laser jammer like some big transports. The China angle sparked extra drama: one poster sketched a nightmare combo — quantum sensors to spot you, heat to finish you — and name‑dropped long‑range missiles. Design nerds piled on, asking if the F‑22 or the never‑built YF‑23’s cooler exhaust would’ve done better, while jokesters dubbed the F‑35 a “$100M hair dryer.”
Stats‑heads asked the gambling question: how many missiles were fired before one hit? Meanwhile, the vibe ping‑ponged between “this is just engineering tradeoffs” and “stealth era’s wobbling.” The only thing everyone agrees on? A hot engine against a cold sky is a big, glowing problem — and the internet brought the chili pepper memes to prove it.
Key Points
- •On March 19, an Iranian surface-to-air missile struck an F-35 operating over or near Iran; the jet made an emergency landing and the pilot was stable.
- •CENTCOM confirmed an emergency landing and said an investigation is underway; Iran’s IRGC claimed responsibility for the hit.
- •The missile, reported as the “Majid,” is described by multiple defense outlets as using passive infrared guidance that tracks heat.
- •F-35 stealth is optimized for radar evasion (X- and S-band) via shaping and materials, but does not reduce infrared detectability from engine and aerodynamic heating.
- •Passive IR missiles emit no signals for EW systems to detect; flares are less effective against imaging IR seekers, and the F-35 lacks a DIRCM system, unlike larger aircraft equipped with LAIRCM.
