Zeus numerix precision guidance kit for 155mm artillery shell

GPS + INS guided

Desi analogue to Excalibur

CEP < 10m in all ranges

Expecting it to be better than Excalibur in the future as it is still under development and testing

Will these kits be procured by army sirji
I mean is there any RFI or rfp or orders

Iird these were developed based on a idex challenge which means(if im right) procurement will definitely happen when ready

What is the difference between an 'expression of interest' and RFI?

From internet-
An Expression of Interest (EOI) or Registration of Interest (ROI) is similar to an RFI and is used practically in the same way.

do you have a pic of SU 30 MKI with condensed water vapor on the wing tips?

No it's not possible unless wingtips are smooth. You won't find vapour lines with Su30 or Rafale.
These lines are Mostly visible on f22 f35 only. Maybe j20.

This is not the old design, but the latest

I can only see 10 weapon stations,where are the other 2

weapon station under the belly , removed

Why capped at 8g, not 9g? What's the angle of attack? 7.5 tons? That's also the max payload of F-16V and it only has one engine.

Im guessing that payload is for carrier takeoff.

8G might be because of folded wings

Since it's a deck based fighter,it has high empty weight, hence low payload. .but it's still high ....F-18 superhornet has 8 tons

TEDBF's internal fuel = 5.5 tons
So empty weight would be 13 tons

G forced is capped due to Naval requirement as these planes need to perform strike missions rather then dog fights. FA 18 has similar G limit or possibly less (7.5 g)

Angle of Attack is purity IAF requirement, How much they want? But also depends on many factors, so there is limit.

7.5 tons is pure weapons load. It is 2 ton more than F16 as internal fuel capacity of F16 is only 3400kg while for TEDBF its 5500kg. So basically F16 have to carry external fuel tank almost always for every sortie (Compulsory) but for TEDBF it will largely depend on mission profile (Optional)

So basically it’s more and more becoming Rafale. I don’t think copying is bad thing when you are having limited amounts of money, infrastructure and expertises.

China are smart in this areas, they quickly managed to close the gap with the West by copying Western weapons.

Teddy reminds me of this fictional fighter, intake seems to be inspired from X32 plane of JSF competition

Lets see how IN future 5th gen looks like, afaik teddy can't be converted to a 5th gen design, a clean sheet will be needed

TEDBF can easily carry 4 Astra-Mk2, 2 CCMs, 2 Brahmos-NGs & 2500kg of external fuel...total of 8000kgs fuel (internal + external)

It cannot take off from Ski-Jump with this payload. And it will be moving like. 2 BVR, 2 CCM and fuel tanks for A2A , 2 AAMs, 1 or 2 AshMs at max for Anti Ship roles

My comment was more of as a comparison between TEDBF and western naval jets.
I comment was not about capabilities of TEDBF as a whole.

G-limit doesn't really matter much IMO. It's capped for the pilot's safety rather than anything else, modern airframes can easily survive more. For example the F/A-18E is normally capped to like 8Gs(as a function of AoA and speed), but the pilot can still press a button that allows more angle of attack than normal

Angle of attack, is also capped for the airplane's safety, because once past a certain angle of attack, the engine starts to have trouble with airflow ingestion and flight control surface effectiveness(in fact it's one of the prime reasons why the Su-30MKI or the Rafale or Eurofighters have canards - more AoA allowability, and better handling at low speeds)

The main thing to look out for would be the instantaneous and sustained turn rate which would decide the kinetic performance of the aircraft in flight
