Indian Military Aviation; News, Updates & Discussions

After potential stealthy SAM hunter, AMCA has potential to engage naval & other surface targets also from stand-off distance.
If we compare some present weapons like AGM-158A JASSM, JSM/NSM, Storm-Shadow/SCALP-EG, Taurus KEPD-350, SOM-J, etc then they're still bigger than IWB, but they can be scaled down.
Below is example of JASSM & JSM with their original dimension compared to 4.2m long IWB:

But their adjusted size variants are being integrated in F-35. Similar weapons can be developed for AMCA too.

Put more Aero India news in here because later one become more specific Indian AF.

Virupaksha radar developed replacing current radar in Su-30MKI.

uttam for mk1a 5.jpeg

Uttam AESA radar for LCA Tejas Mk1a. This upgrade version of basic Tejas Mk1 is showing more weapons set but still also late from previous schedules.


The X account of this Vayu also shown 1:1 Model of AMCA, and not first time this model has been shown in Aerospace Exhibition. Well it is still model while KAI KF-21 and TAI KAAN already working prototype stage.

Below just shown photo of Tejas Mk1a, which my take should be in front line Indian AF squadron soon. Well soon in Indian plan can be next year or next five years.

Trump officially offering F35 to India. Thus the presence of F35 vs Su-57 in Aero India is real sales campaign. Perhaps why Rosoboron offering Joint Production of Su-57 as seems at this point unlikely US will offer Joint production to non F35 program partner nation like India.

Still with Trump, any offer as long as profitable enough for US can happen. Bit different stance Trump has with India, it is more soften stance in my opinion to coerce India opening the market.

There're signs Turkiye path to F35 might be reopen. US afterall going to reward Turkiye to their efforts on getting rid of Assad family from Syria.

Trump can change US standing on F35. Less then 2 decades after F16 first fly, US then open more market for F16 outside Euro and Asia main allies. Perhaps he believes it is time too for more F35 market.

They kicked Turkey out for having S-400s, but India's S-400s are ok??
India isn't in NATO. It doesn't have access to any of NATO's command structure. And India is much bigger than Turkey, & has bought a lot (most, for many years) of its weapons from Russia/the USSR, & until recently, nothing at all from the USA. Getting India to buy US weapons could be seen as a change in political alignment. Also, it's Trump. He isn't interested in & probably doesn't understand security. For him, everything is about "deals", & personal relationships.
 
IWB versions of ARMs (Anti Radiation Missiles):
Kh-58UShKE, 650 Kg, 4.2-4.8m long, 380-400 mm diameter, 149 Kg warhead, 250 Km range, Mach 3.6
AGM-88G AARGM-ER, 467 Kg, 13'4/4.06m long, 292mm diameter, 68 Kg warhead, 300 Km range, Mach 2.9
But Rudram-1 cannot fit in AMCA'a IWB.
Rudram-1, 600 Kg, 18'/5.5m long, 340+/-mm diameter, 55 Kg warhead, 150-200 Km range, Mach 2
Rudram-2 & 3 are going to be even bigger.
If DoD makes IWB version of Rudram, it will make AMCA a dangerous SAM hunter.
There were Ramjet version missiles tested earlier but AARGM-ER uses modified solid fuel rocket motor.

Continuing the chain of posts for weapons in AMCA's IWB which is officially quoted 4.2m X 2.2m,
After observing the designs of all BVR-AAMs made globally, and intention of F-35 & J-35 to increase their IWB capacity to 6 AAMs, I had shown by diagrams that only 4 big-fin Astr-1/2 AAMs can fit in IWB but,
6 staggered Astr-2 short-fin AAMs (like AIM-120-D in F-22),
or 6 modified Astr-3 SFDR,
or 8 folding-fin Astr-2 AAMs can fit in (like Chinese PL-15).

I took the CAD of Astr-2 big-fin by artist "Akela freedom" & edited in Paint to match short-fin version made by artist "Kuntal Biswas" which is also identical to AIM-120-D. So the forward fixed fin has been shortened & shifted forward & rear fin leading edge more swept back, that's all, simple quick edit.

Now we can see the comparison more clear & precise, 4 & 6 big-fin AAMs vs 6 short-fin AAMs in the outine of official dimension of IWB. Unfortunately an updated CAD is not released yet by any artist or DoD.

1739618399487.png

I did this few weeks back but I waited for Aero-India, hoping they would officially increase the IWB capacity & showcase, but didn't happen. But this is not an up-hill task & can be done easily till IOC jet.

1739618431828.png

There is no separator wall in the IWB. 1 door panel slightly overlaps on the panel of other side door, means both doors have to open full to drop any weapon, exposing full IWB. I hope this gets corrected in IOC jet.

Turning India away from Russia has significant value for US's Indo Pac strategy, which seems to be Trump's fixation.

As for Turkiye, the situation has changed since they were kicked out of the F-35 program, namely Assad's Syria is out of the picture and Iranian proxy / Hezabollah is cripped. They / Turkiye, with their fight against PKK and influence in north Syria/Iran might benefit from it.
 
There is an indication by IN about 5gen TEDBF, means complete stealth.
Current TEDBF design could be scrapped or heavily modified.

1740504637048.png

So this is different from the earlier linear roadmap which IMO is contributing problem rather than parallel, independent projects.

1740504658964.png
1740504686835.png

We have our RAMs & RAS now, we need geometric structure.
It's good that IN understand now that Naval jets won't get threat concession by enemy SAMs, AAMs, jets. :D
The era of 5gen is said to begin with B-2 & F-117 revealed in 1988, then YF-22/23 revealed in 1990. They were developed in 1980s & initiated in 1970s. So we are 30-40 years behind that way.o_O

But we are 15 years down the line with AMCA & many common components with MWF, TEDBF. There are 3 options now -
- tweak AMCA like F-35 A & C models.
- tweak current TEDBF design. The MWF can act as TD like X-35 & final Naval TEDBF can be stealthy like F-35C, although inflated to 2-engine jet.
- cleansheet AHCA with stronger engines for a good airframe TWR to take-off & carry sufficient minimum custom weapons.
Our engine JV shoud cater to this, meanwhile we should arrange interim engine for prototype.


1740504724806.png

Also, a panic has been created about humidity, salinity, higher CAPEX & OPEX of naval jets, etc as if it is a solid barrier in way of tech advancement. It sounds like 4.5gen is the end of line & pinnacle of Naval jet tech & no future version of RAM & RAS can protect the jets in affordable cost.:D On land/sea, in space, deep under water, if something needs to be done, will be done. So let's not fuel this point which goes against stealth naval jet rather than being constructive & progressive.

The next carrier should have EMALS which should be sanctioned a.s.a.p.

If anybody has more 2D front views, diagram, sketch, etc, please share.

So far we have seen multiple CADs & static models with slight differences.
Neither ADA nor the 3D artists release basic schematic diagrams, cross sections, configurations, etc. The ones available so far are low resolution & inadequate.

1742018591278.jpeg

It is difficult to confirm how the inducted jet will look like & its capabilities.
So taking the most convincing CAD front view & superimposing the IWB dimension of 2.2m width & 0.75m depth, along with BVR-AAMs from TEDBF CAD, it seems 6x Astr-2 short-fin version with 178mm body diameter would fit in IWB easily with or w/o staggering.
SWB is also possible.
With 1.5 ton IWB capacity, 6x BVR-AAMs + 2 CCMs = 6x154 + 2x88 = 1,100 Kg, 1.1/(12+6.5+1.1)=5.6% of STOW.
Wet T/STOW ratio = 2x98 KN / 9.8 / (12+6.5+1.1) = 1.02
With 50% fuel used & firing 4 BVR-AAMs, with 2 CCMs & 2 BVR-AAMs left, wet TWR = 2x98 KN / 9.8 / {12+3.25+(4x154 + 2x88)/1000} = 1.24

With this lease contract, Airbus has got a new potential customer for the A330MRTT.
Indian Air Force to lease A330 MRTT from France

|"The wet lease is expected to be finalized during the 2025–2026 financial year. The IAF remains committed to its long-term plan of acquiring six A330MRTT aircraft."|
So if the Indian Air Force is satisfied with the A330MRTT, they will at least order 6 new ones.



The first 56 helicopters are for the airforce, the others are for the army.

Realistically why would India consider the only other option given the horrid KC-46 program mis-steps? A330MRTT is a safer bet with faster delivery likely and zero political sinkholes from IOTUS.

I don't know why some in India still bother with this Tejas Mk2 concept program. For me it is wasting resources as:
  1. It will not give any edge with current Rafale already in Indian inventory or others candidates that now bidding for MRFA program,
  2. HAL still not deliver all other Tejas Mk1 and already late for Tejas Mk1a. How far longer it will gw late for this Tejas Mk2 ?
  3. Resources that better use to improve Tejas Mk1a, build assembly and localisation for foreign design MRFA (potentially more Rafale), and focus all the rest of Resources to AMCA. India already very late to catch up with China for 5th gen let alone 6th gen fighter development.
