Wouldn’t it be cheaper, in the context of a mid-maturity defence industry, to develop a manned aircraft rather than a UCAV?
The proponents of this type of idea are thinking defencive air defence fighter to disrupt a stronger adversary’s air campaign. We are not talking about what USAF/USN/USMC or RAF need, think more like Taiwan, Singapore, Georgia, Kuwait, UAE, Latvia, Poland, South Korea…

Quick over-draw of stealthy skin…
From a configuration perspective the beautiful Draken might lend itself to stealth – inherently S-shaped intakes, large side areas for internal weapons stowage etc.
With a modern non-afterburning Turbofan, subsonic performance, twin tails etc…
On a related note, coolest plane ever!
I’ve been hoodwinked! Thanks for pointing that out. Venezuela does plan to acquire some K-8s, or already indeed has- right?
Yes, those K-8 pics are legit. I’m confused what the PS challenge is about. Afghan Mils?
Ok, if we’re going that small, with a small RCS, and we’re talking about a high technology capable country, let’s look at going all out with a UCAV operating in a “missileer” function…..
Interesting ideas, but I can’t help but think you’ve just made the idea a lot more expensive and technologically risky than it needs to be whilst simultaneously eliminating virtually all of the potential market. Sudan could be enforced by any NATO fighter, stealthy UCAVs are completely unnecessary.
If you place yourself in the position of ROCAF or ROKAF, or IAF (etc) can you not imagine a small LO point defence fighter would be useful? And that when you limit the mission to disruptive point defence against a larger/determined enemy over your own territory, can sufficient LO not be done a lot cheaper than F-35 et al.
PAK-FA is a 5.5 generation fighter
Just found this one…
And not quite a fighter….

Wow indeed.
Great minds think alike, …and sometimes fools think alike too! 😀
Distiller, interesting ideas. Sounds sensible for USA but some of the technologies you mention could be done without to reduce development risk, maintenance and cost. I’m thinking either an export fighter for likes of BAE Systems, or an indigenous program for likes of Taiwan, Singapore, Israel, Georgia etc. Countries like Syria, Venezuela and Iran are even more plausible I guess.
For aerodynamics my unqualified gut feeling is a relatively thick delta wing with small unmoving canards to reduce stall issues. No leading edge moving parts.
Internal bays I think are worth it – semi-recessed missiles probably have a largish RCS because they create right-angle reflections(?).
Again, not a specific design just illustrative of the concept.
Years back I was thinking along similar lines. If you don’t have a radar, why not have a nose inlet?

Other ‘planeman pocket stealths’ from a few years back


This one is a strike optimised design, a bit too large…. cheap F117 with South African PGMs…
Just a bit of fun
I want UAC to win, being a capitalist and all. About time USA realised what free market actually means, lol.
Not so much the vapour trail as the wingtip vortices of the aircraft.
Radar can currently detect wind shears and pressure changes.
Its all a question of algorithms and processing power. In time, nothing within the atmosphere will be “stealthy”… but that time is probably quite a long way away yet…. maybe.
Great answer, very helpful.
how much would that reduce the combat radius by?
So the Syrian MiG is in Russia-proper?
Syrian MiG-23. Anyone know the nationality of the L-39 on the right of the pic?
