India AMCA Program

[Bhartiya Sainik]

If AMCA's IWB can be widened & Astr-2 AAMs staggered then similar to F-22, 6 Astr-2 AAMs can fit.
In A-G only mode, it may allow total 16 SAAW bombs.

In persuit of improvements, there might be some good news.
The unofficial tweet might be true. I lately got an infographic showing AMCA's IWB dimensions to be 4.2m long, 2.2m wide, 0.75m height. The dimension is not mentioned in many other posters.

The Astr-1,2,3 AAMs have same length 3.84m. But unfortunately due to big fins of Astr-1, even staggering doesn't help to fit 3 AAMs/bay, total of 6.
But the Astr-2 with shorter fins can easily fit with staggering.
Bcoz of limited info coming out gradually, the older CADs couldn't show the actual weapons capacity. If we superimpose the actual IWB dimensions to match with Astr-1,2 AAMs then we can see the difference.

In latest CAD by artist Kuntal Biswas who sticks to official specs, the IWB seems to have been widened, although a bottom view with exact dimensions & capacity is not available yet. The below pic is 2.5 months old now but nobody posted.

More good news to come gradually.

Fitting Ramjet missiles is a challenge bcoz of their long intakes, it becomes difficult to stagger them.
There is an early render by artist Kuntal Biswas of 2 Astr-3 SFDR /bay, total 4 AAMs, but pic is angled, the bay is short with big gap in between.

He has also made multiple CADs of Astr-3 SFDR BUT with different fin & ramjet intake dimensions.

The 3rd one is the only one with bottom view so if we resize it with IWB then still it will be a TIGHT UNSAFE fit of 3 staggered AAMs/bay.
And if we consider 3 staggered Meteors (AAM CAD by artist "AkelaFreedom") then although it is 6" shorter but its intakes & fins seem to be wider & overflows out of bay.

Editing in MS Paint, Photoshop, etc can produce inaccurate errors.
It is best accurate if the artists themselves produce this kind of images. But most of them don't.

News channels & elsewhere people are talking abot MRFA & only 2 final candidates - Su-57 Vs F-35.
While F-35 would be the most tempting honey trap so far, the Su-57 is under fire too not seen as proper full 5gen stealth. There are many things which can be learnt from current 5gen jets. Some of us are also concerned that it may impact AMCA program. The following is a brief comparison. The "possible" features have to be TIMELY implemented expecially when global tech evolution is at 6gen R&D level.

If the Ramjet intake is shortened then 6 Astr-3 SFDR AAMs might fit relatively better. But there could be military safety specs which may or may not allow this.

We see Akash-1 SAM also has Ramjets which don't extend all the way backwards.

The intake fairing in Meteor is long bcoz it houses some electronics, fin actuators. Same could be with Astr-3 SFDR. But if the AAM body can be adjusted then it can favor AMCA.
