Now ADA is in a dilemma on how to cater to IN.
- tweak AMCA to N-AMCA
- or tweak TEDBF to ATEDBF
- or new design
- when to officially initiate
- define timeline keeping in mind global tech advancements.

AMCA & current TEDBF would use same engines in twin config. so their dimensions, weight, size are also identical.
Following is a scaled comparison as per their width:

This comparison is identical to F-16 Vs F-35:

Although unofficial CADs are not the ultimate thing, the AMCA CAD looks relatively matured but if the TEDBF needs to be tweaked then clearly some things have to be modified like -
- lengthening & widening fuselage.
- reshaping narrow cockpit & over-sized canopy.
- create space for frontal sensors.
- adjust smaller intake area.
- pull up intakes & increase belly width for IWB.
- reduce bulky shoulder like fused CFT.
- remove vertical tail to twin canted ones.
- blend the wing more into fuselage.
- perhaps increase wing width/area little more.
- remove wingtip hardpoint by conformal tapered EW antennas.

IDK how i forgot this post 1 year back.
We noticed as per available diagrams & official dimensions that AMCA & TEDBF have identical span, dimensions, cross section at some places, like height from belly to cockpit ceiling looks almost same.
This means if AMCA can have IWB so can TEDBF.

For notional AG load I used CADs of AGM-88G, JSM, AGM-158 JASSM.
For AA load i used Astr AAM CAD.
When we superimpose AMCA's IWB dimension box on both jets with AA, AG & mixed load, it looks like this -

We see that TEDBF needs some tweaking like i mentioned in last post. It would be like X-35 to F-35.

> IN indicated 5gen TEDBF at Aero-India'25. Some say it's for new CATOBAR IAC & 4gen TEDBF is for STOBAR IAC. IMO just like adjustment with Rafale has been done, similarly 5gen jet can be operated within STOBAR paramaters till CATOBAR IAC is made, otherwise from shore bases.

> Mechanical & Aero engineers can tell better, but i 've been thinking of putting a half-length catapult before ski-ramp, but it might reduce under deck space.

> Beast mode can never be compared with internal load, but -
- newer gen comes with newer architecture/framework, weapons, strategies, tactics.​
- Modular IWBs, CFTs can be implemented like in F-15 & planned in GCAP.​
- Like Su-75, a longer centerline IWB can hold Brahmos-NG type AGM.​
- A stealth jet can fire bigger AShM carried externally, but where/when stealth will be needed, a 4gen jet can't do it.​
- Ship of any size can be precisely hit by smart weapons & immobilized, sensors blinded.​

> Before writing further on reducing pilot life risk by 5+gen TEDBF, i collected many points & divided them into 2 groups depending upon inclination more to 4gen or 5gen.
So, later in another post i'ld put the 5gen inclined points.

> 1st, for 4gen lovers i would like to do an approximate scaled comparison of this 4gen TEDBF with USN 4gen TEDBF the F-18 SH bcoz they would have same 2x F414 engines. And then present some points in my opinion.
NOTE - AFAIK the EWP'll be implemented, but dorsal CFTs have been cancelled due to technical/performance issues, still i'm considering that theoretically, analogous to a hypothetical model. Considered CFT weight = 2x400 Kg & fuel in them = 2x1.6 tons, EWP weight = 408 Kg & its payload = 1,134 Kg.

> In emerging 6gen era, behind global 4gen jets are different nation's/people's different justifications -
+ Everybody want to save money💰 , newer stuff is costlier, older stuff is cheaper, people can spend saved money on other assets, salty marine environment makes maintenance costly, etc but -​
- defence has always been costly matter in every gen's era - 2gen'll be costly, 3gen'll be costly, 4gen'll be costly.​
- salty marine environment has never ever stopped R&D from 1st gen towards 5gen then 6gen with RAM, RAS improvements.​
- India is socialist economy, not capitalist, if only the beauraucratic system can be tweaked.​
- Economise but also field future tech IN TIME side by side, which didn't happen so far.​
- Economy should be boosted by absorbing citizens into industry & shifting from more consumer to more producer model. IT boom happened in 1990s, this is mid-2020s. Exploit supercomputing, AI/ML, robotics, etc. Vehicles, appliances, etc makers should compete globally.​
- Whichever Force doesn't have budget is destined to get defeated by technology.​
+ continue old business, market🤑, ecosystem by R&D/producer nations for lagging/importing nations, whiile India's present & future exports are skeptical.
- USA supplies/services Taiwan, S.Korea, Indonesia, Singapore, Pakistan, Philippines, Thailand, Israel, UAE, Bahrain, Jordan, Egypt, Saudi Arab, Kuwait, Greece, Turkey, Poland, Romania, Denmark, Norway, Portugal, cannad, Chile, Argentina. Only S.Korea & Turkey have made their own jets KF-21, Kaan.​
- Russia after big history, supplies/services Algeria, India, Iran, Etheopia, etc.​
- UK supplies/services Qatar, Turkey, Saudi Arabia, Austria, Italy, Germany, and Spain.​
- France supplies/servies Egypt, India, Qatar, Greece, Croatia, Indonesia, UAE, Serbia, Ukraine.​
- China trying to expand beyond Pakistan, Indonesia, Nigeria, etc.​
- India needs to get out of the above list of importing nations, but making too many new 4gen will create import tender for future 5/6gen even after AMCA which cannot be only 5gen for big India. STOBAR AC can have medium 5gen & CATOBAR AC can have 5.5-6gen N-AHCA.​
- Whether all above customer nations will buy Indian 4gen LCA, MWF, TEDBF, etc or USA, China, EU, Russia will try to sell them affordable 5gen is debatable.
They're making modification of exisitng 4gen since past few decades while India attempting multiple brand new 4gen from scratch for next few decades.​
+ 4gen can be given many MLUs - radar, cockpit, Networking, composites, RAS, some RAM, sensor pods, LR weapons, even a DEW pod, but -​
- still 4gen body'll be most visible object in sky to be hunted by 5gen.​
- using LR weapons on 4gen is compelling thing to use their last series, not ideal/desired/efficient which is actually with stealth sneaking closer & increasing NEZ, that's where 5gen got limited IWB & 6gen will fulfil.​
- Stealth jet has higher chance of breaking lock.​
- And now 5gen also threatened by 6gen R&D.​
- Hence on both sides of battle if USA, China, EU, Russia fight eachother in proper blown war not just skirmishes, in 2030s/40s whenever, they'll also suffer big 4gen losses,☠️that would be the job of 5/6gen
But 1 of most ignored point is that last series of 4gen'll hide behind 5/6gen & UCAVs if AI fully matured, while India's 5gen & UCAV R&D sluggish & no 6gen R&D -​
- USN has F-35, will have FA-XX,​
- PLAN is ready for J-35, will have J-50,​
- Russia is sluggish, but might disclose next gen successor of Su-33 any day.​
- France will have N-FCAS, could relax & jump to 6gen as Russia is sluggish.​
- Indian 4gen TEDBF will shout "AMCA help us!".

+ UCAVs will cover 4gen like bodyguard. Sure, that's the future to protect even the 6gen. But -​
- it needs agile, true naval AI-UCAV with ATWR>1 which is difficult for boomerang shaped UCAV.​
- Land based UCAV R&D is sluggish, naval UCAV TD not there yet.​
- Next it needs full scale model test on STOBAR, CATOBAR.​
- Enemy will also use their UCAVs against 4gen, 5gen.​
- UCAVS can also be put in 5gen, 6gen categories.​
- Chinas has shown at least 5 types of UCAVs, some are manned fighter sized.​
+ 4gen to be used in uncontested areas, in other words for brooming, mopping, against weaker adversaries, but-​
- this happens after 5/6gen does SEAD/DEAD,​
- 4gen can also do SEAD/DEAD with networking & LR weapons but enemy SAMs, AAMs are also getting networked IADS & LR.​
- IADS will be fortified by layered defence.​
- hence this still doesn't reduce threat to 4gen by mobile SAMs, MANPADS, IADS, 5/6gen.​
- Enemy's Stealth jets are like moving 'contested area'.​
+ People want to be self reliant free from imports, that's good, but should happen IN TIME bcoz a jet is matter of 20+40 years. ADA slide indicated 4gen TEDBF in 2038+ & wind tunnel test also yet to happen. China's economy & military was like India's decades back, but -​
- 5gen FC-31 paperwork began in 2007, flew in 2012, 4gen LCA-N flew same year.​
- After AMCA paperwork in 2010, IN approached ADA for 5gen jet but ADA stating -
= N-AMCA conversion not efficient,​
= Navy-1st design'll impact & upset IAF,​
= no cleansheet design either bcoz ADA is tiny, lacks manpower for CAD/CFD, wind tunnel tests of multiple projects, or previous govts. not giving funding, etc, but 5gen to be built on top of brand new naval 4.5gen which was wrong bcoz, there's experience from LCA, LCA-N, MWF designs & started AMCA project & DRDO was working on RAM, RAS, etc.​
- IN had to settle for 4gen TEDBF & paper work in 2019, Otherwise a cleansheet 5+gen TEDBF TD in parallel to AMCA would be ready in 15 years by now.
- 6gen J-50 speculated to be naval, flew last year, India doesn't even've official diagram of domestic naval/AF 6gen but looking for possible naval FCAS, AF-GCAP.​
- 5gen J31/35 ready now, the 4gen design has been frozen🥶☃️ to make in next decade.​
- Russia also gives surprises. After revealling Su-75 in 2021, what if it revealled & offered naval Su-75 or some other design?​
- IMO too many Rafale-M also not good. Earlier i thought that like plans for converting KF-21 to true 5gen, if 4gen TEDBF airframe can be upgraded like that then some LSP can be done. 4gen TEDBF could've been flying TD by now like X-35. But it's too late & wind tunnel test yet to happen hence IMMEDIATELY start stealth design exploiting supercomputing, AI/ML, etc, otherwise it'll automatically become problem later like MiGs as AMCA nears completion, it means when things are too late then no option is cheap overall, today appearing cheap, later it'll backfire.
Other 4gen reasons around world -
+ designers wan't to see their creation fielded,
+ revenue for future R&D, black budgeting
+ corporate profit
+ bonus of lobbysts
+ no R&D organisations for pure consumer nations
+ industrial rivalry
+ international agendas & interests
+ political intentions
+ cheap but risk to pilot's life
+ increasing falling squad strength
+ overconfidence, over-optimism with peace,
+ ignorance of global tech advancements,
+ some other bitter & natural facts of war.

Pitfalls can be avoided where others got compelled or stuck.
> If AMCA is expected to kill JF-17, J-10, F-16, Su-30MKK, J-11, J-15, J-16 then be ready to get LCA, MWF, TEDBF, MiG-29, Su-30MKI, Rafale killed by J-20, J-35, J-36, J-50.‍

Remaining points although i've also drafted in notepad but will make post very long, will be expanded in 5gen TEDBF posts like -
- anti-ship mission
- big weapons
- converting AMCA
- converting 4gen TEDBF
- Cleansheet design
- tip & body of spear
- beast mode Vs steath mode
- STOBAR Vs CATOBAR, lifts, arrestors
- 5gen jet size & weight
- progressing with each gens
- 5gen TEDBF geographical positioning in seas.
- possible future naval threats
- rework, redesign
- 5gen performance Vs 4gen
- UCAV compensating lack of 5gen.

And from tech PoV there's nothing to panic as such on all these points for techies, it's all daily paid job & India got AI/ML, robotics, supercomputing, JV & collabs, millions of techies now for PPP. Every domain from outside looks tough, like surgery.
The thing to panic is that time-bound & result oriented management is needed with accountability & free from molopoly to reduce life risk of pilots.
