The F-35 is designed to be able to break into and defeat modern air defense networks.

The gripen is a much less capable non expeditonary platform designed to maximize asymmetric losses if sweden is invaded. As a small country sweden has to follow a porcupine strategy to deter invasion.

Presently the actual comparable to the F-35 is attritable drones, which is why every mid-size and major power is developing them.

The Russians have been trying to use attritable drones for years to break down the Ukrainian IADS and have not yet succeeded. Meanwhile the Israeli F35 fleet with no direct American support was able to crack open Iran’s air defenses at the start of the Twelve Day War with relative ease.

Israel used long range air launched ballistic missiles (ROCKS) and cruise missiles, mostly from F15s, to degrade Iran's ancient radar network and S300s (which allegedly weren't moved around much). That was before the invasion, so Iran didn't have much long range radar coverage when the war started.

The shahed/geran is just a low cost cruise missile. The f35 comparable is a loyal wingman that does manned/unmanned teaming and carries A/A and A/G.

[XorNot]

Loyal wingman aircraft would have to be stealthy though to do it.

The whole point of the F-35 is that it is a stealthy platform with a very advanced set of targeting and weapons capabilities: but the issue is a similar capability drone would basically have a similar price tag since the expense of the pilot is minor in that case.

Like plausibly the best autonomous F-35 platform would just be an F-35.

[TheOtherHobbes]

Low-level drones are also stealthy. If they're not stealthy enough you can send them in bulk to overwhelm defences.

Ukraine's success with precision targeting of Russian assets would have been unthinkable with a fleet of F-35s and associated missiles because of the cost.

Cheap, smart, disposable drones are orders of magnitude cheaper and at least as effective for many mission profiles.

[XorNot]

The F-35 would've been used to take out the air defenses and cheaper munitions used for everything else.

Which is exactly what it was used for in Iran.

[fragmede]

It's not the expense of the pilot but the fact that the human pilot is subject to human biological constraints. Ie they black out after 9 Gs or so. An autonomous platform you'd want to design to be able to routinely do outside that envelope in a way that a platform designed for a human occupant is not.

[XorNot]

Its a nontrivial exercise to design a plane which can regularly do more Gs then that though.

There's no drones currently in development AFAIK with this goal either - the focus is on getting them to do useful mission without a pilot, rather then out dogfight or outmanoeuver missiles.

Basically the point stands: a hypothetical "better then F-35" drone is likely more, not less expensive then an F-35.

[throwaway85825]

The US lost several aircraft rescuing the downed pilot in Iran. Not necessary with drones.

[throwaway85825]

There are at least a dozen stealth loyal wingman programs/prototypes.

[ls612]

Such a platform does not exist today in active service in any military (so far as we know).
