I don’t think EO DAS is a waste of time/money. I do question whether it should’ve been part of the base F-35 program.
Greater power requirements and associated engineering challenges + a giant “hey, look at me” beacon — no thanks.
I think passive sensing will come increasingly to fore in aerial warfare going forward.
^ They’re aiming for 180kN from WS-15 IIRC. Lower TWR than AL-41/F135 tho, which fits with observation I made early on — that it appears J-20 could accommodate larger engines than are currently fitted.
I am surprised that nobody has attempted a direct volume (or at least area) comparison between F-22 and J-20 main bays.
^ It’s a line from Dr. Strangelove (“Mr. President, we must not allow a mine shaft gap!”) but playing off the double meaning of ‘gap’ in this context. 🙂
I would’ve thought Russia would aim for a smaller, cheaper carrier so that they could afford to field enough (3-4) to be militarily useful, as opposed to a glorified status symbol. No doubt PAK FA operations would be greatly eased with a larger carrier, but then I am sceptical that we will ever see a navalised PAK FA.
We cannot allow a bay door gap!
Looks like the French were ahead of the game with MICA.
And yet Russia sells arms to Vietnam whilst simultaneously enjoying a much better relationship with China than India does.
Sounds like they don’t really know what a 6th generation fighter is. They should start with the questions, what is the fundamental weakness of the 5th generation fighters that can’t be fixed with upgrades?
Range and Payload. Not a weakness of the ‘5th generation’ per se but rather a weakness of the platforms the United States has chosen to field in relation to future strategic environment. The engine programs currently in the works will improve the situation somewhat, but a comprehensive solution will require new airframes.
Cross-post from Chinese Air Power thread:

I think folks are overestimating the oppositional character of India-China relations in comparison to US-China relations. Folks who see India as a more promising arms supplier to Taiwan than the United States going forward are dreaming.
Incidentally, I wouldn’t say we’ve seen the last of major US arms sales to Taiwan. I think the US political environment in the mid-2020s could well be favourable for such transactions.
India has expressed an interest in acquiring the submarine and both the Russian design bureau and the shipyard that will construct it
I was skimming the article and read this bit in isolation. Reaction: “wtf, good luck with that.” 😮
Is there any indication of how India will eventually go about constituting its own nuclear submarine capability, i.e. Su-30MKI style foreign design with indigenous mods and production vs. Tejas style indigenous design with foreign consultation?

Ok, Y-20 goes on the ‘sexy airlifters’ list. :eagerness:
Clearly, India could find a market in such countries as Vietnam and possibly Taiwan for its Arms. Hopefully, it will take advantage of the opportunity……………time will tell.
Unlike Vietnam I think Taiwan would be far too sensitive a candidate. India’s relations with China today are better than at most times since the 1962 conflict, and neither nation is interested in throwing that away.
I don’t know about that. Nonetheless, many of the weapons are offensive in nature. Either designed to project power or support land operations. Especially, the maritime assets like Aircraft Carriers and Amphibious Ships. Which, clearly are a threat to countries that have island disputes with China. Like Vietnam, Philippines, Taiwan, Japan, etc. etc. etc.
It is reasonable for other nations in the region to be concerned at the development of Chinese military capabilities and to respond accordingly. It is presenting this growth of China’s capabilities as some kind of militarisation with ominous/expansionist undertones that is the problem. China’s military spending has remained stable as percentage of GDP for decades, and that level is within the normal range, lower than America’s. If China was really embarking on a program of military expansion, things would look very different.
OTOH Chinese behaviour in recent years tells another story. Regardless of motivations, China has succeeded in spooking any number of regional nations into a closer embrace with each other and the United States, a nation which was not particularly popular in the region pre-2009 or so. In succeeding in aligning disparate regional powers against it, China has undone decades of ‘peaceful rise’ rhetoric and basically shot itself in the foot. Of course, China’s loss is America’s gain.
