Which systems are out there that are actually comparable to the JSF? Both the Eurofighter and the Rafale are one gen older (not sure if that actually matters that much so). Which leaves the Russian and Chinese planes, for which cost is hard to come by.

Chinese FC-31 is close to the F-35 (in design and theory, but who knows about actual performance), but it's not in production yet.

Looking at pictures, it has two visible round jet nozzles which suggests it has much higher radar cross-section and IR-signature than F-35.

It's extremely difficult to evaluate RCS by looking visually at an aircraft. Who would have thought that the F-117 would be stealthy? And the reason the F-35 only has one engine is because it has a much higher thrust than the RD-93 on the FC31. This increase in thrust "might" increase its IR signature, and neither has any IR shielding like on the F-22.

Maybe the f-22, although that isn’t in production anymore
