Funding the Sixth-Generation Fighter?

Some years ago I took up the subject of the sixth-generation fighter aircraft.

I discussed what features are thought likely to distinguish such an aircraft. (Think artificially intelligent, hypersonic, armed with directed-energy weapons.) I also considered whether these as yet hypothetical planes might or might not actually appear within the predicted time frame--the late 2020s or 2030s.

I offered three reasons to be skeptical of this.

1. The turn from great power conflict to small wars, making quite different demands.
2. The rate of technical progress may be too slow to allow for the kind of aircraft imagined in that time frame (perhaps in itself, perhaps relative to other, more dynamic fields).
3. Economic stagnation may leave air forces unable to afford such aircraft.

It would be difficult to deny that great power conflict has resurged since I first wrote that piece (in 2010).

There is also more bullishness about technical development now than then. How many of the really relevant technologies will emerge remains open to question. Even where artificial intelligence is concerned expectations now seem more moderate as compared with a couple of years ago--while as the research into hypersonic weaponry shows, anything like a truly viable, multirole, production aircraft capable of hypersonic flight remains quite some way. I would not bet on such aircraft being anywhere near ready for service in the 2020s. Still, it seems to me precipitous to wholly rule out at least the technical possibility of such aircraft for a full generation.

However, the third reason, the matter of cost, seems at least as significant as ever.

Consider what came of the fifth generation of fighter. The Europeans decided not to bother, making do with the "generation 4.5" Eurofighter Typhoon and Dassault Rafale. The Japanese, Russians, Chinese only belatedly pursued programs. And even the U.S. Air Force, initially intent on 750 F-22s, cut back its order by three-quarters, making do with a mere 187 operational jets.

One can attribute much of this to the end of the Cold War, admittedly. The Russians and Chinese did not have the resources--the former because of economic collapse, the latter because if fast-growing, they were still relatively cash-strapped, and (wisely) prioritizing economic development. This let the U.S. and its allies take it easy there, the more so as they had other priorities in an age of sluggish growth and intensifying economic competition, and in which, at any rate, small wars seemed the principal concern.

Still, as noted earlier, if the Russians and Chinese only belatedly fielded their own systems, they did so all the same, and in an international scene that had grown much more aggressive in comparison with the 1990s. However, after developing the Sukhoi-57 the Russian government decided to hold off on actual production. This may seem understandable given Russia's attempting here to fund superpower capacities (cutting-edge aircraft production) on rather less than superpower resources (even in PPP terms, its GDP is about 20 percent that of the U.S., the European Union or China). Still, in the face of what American policymakers regarded as a more aggressive scene, the Pentagon has opted to buy brand new F-15s (upgraded, but still F-15s, and not even stealthy "Silent Eagles" either) to fill out its ranks. There has been much argument over the rationale, with many downplaying the question of cost savings--perhaps, too much so, in light of the uncertainty involved in the eventual cost of the more advanced F-35, and for that matter, the fate of the program more generally. (Production has only scarcely begun, a mere four hundred of those thousands of intended units rolled off the line to date, while criticism of the high cost and questionable performance of the aircraft continue.)

In short, even the fifth generation of jets has proven prohibitively costly. It seems a certainty that, if they do prove technically feasible, a sixth generation of fighters will be much more costly than these--the billion dollar fighter upon us if the trend holds--without necessarily offering value for the money (other systems might prove a more efficient way of doing whatever job is at hand), or the resources being there even if they do. (Our economies have been a stagnant for a decade now, and could easily remain so, while one does not have to incline to the more apocalyptic visions of climate change to see that worse may be in store here.)

Indeed, thinking of the talk of sixth generation fighters I am reminded of other high-tech roads not traveled, like the '50s-era visions of ultra-fast, ultra-high-flying, ultra-long-range shooting superjets (YF-12, F-108) that should ring very familiar to anyone who has actually considered the things a sixth generation fighter is supposed to do (be a hypersonic, near-space jet with longer-ranged missiles and even "frigging laser beams"). Instead fighter design traveled a more conventional, less spectacular, but arguably more practical course. So does it seem likely to do again.
