DRDO’s successful flight test of Smart Anti Airfield Weapon

Hyderabad: DRDO has successfully conducted captive and release trial of indigenously developed Smart Anti-Airfield Weapon (SAAW) from Hawk-I of Hindustan Aeronautics Limited (HAL) off the Odisha coast on January 21.

The smart weapon was successfully test fired from Indian Hawk-Mk132 of HAL. This was the ninth successful mission of SAAW conducted by DRDO. “It was a textbook launch, which met all mission objectives. The telemetry and tracking systems installed at Interim Test Range, Balasore captured all the mission events,” the DRDO said in a release, on Friday.

Why not make a naval variant of AMCA instead of TEDBF?

Please check TEDBF thread.

Wait...
Wouldn't amca have TVC pitch,yaw and roll?

AMCA will most probably feature 2D TVC. DRDO worked a lot jointly with the Russians on this technology few years back.
Also, HAL has some experience working with TVC gained by assembling the AL-31 engine in its Koratpur plant.

In Mark2. For Mark1 the engine is still F414, although it has option for TVC, as was offered in MMRCA... So it depends on whether India is going to acquire the usual version or not (F404-IN20 too is unique version is tailored for India).

AMCA Radome with serrated Joint

Do you have some evidence claiming this is AMCA Radome?
This just looks like some random computer generated image.
The serrated joint pattern doesn't make sense?
Why are their second set of serrated Joint in left bottom corner?

It is posted by Ananth krishnan very credible handle. Second set of serrated joint may be side looking radar or DAS.

This was the previous design for DRDO tableau. Now I think the design got changed.

Samvijay SIGINT cum COMINT system was deployed during Op Juniper in Doklam and now in Eastern Ladakh along LAC.

Its meant for high altitude areas. So the entire package is housed in a Stallion 4 by 4.

After seeing this scale model I think this is a pretty good Stealth Design , Nose section is very interesting - better stealth , good airflow for engine , better stealth from sideways. The air intake structure( side ways) much similar to F22 and offers better stealth features( unlike that shitty J20 ) top section also offers better stealth from AWACS which searches from above .
No EOTS , two patches in the nose section indicates may be Some sensors like cheek mounted Radar , No IRST , The HySIS spectral imaging satellite can directly feed into AMCA so it will get EOTS&IRST like sensor support without sensors , probably they will be added in the MK2 or may be it is already there .

Think they want a super Stealthy Aircraft without any protruding surfaces , May be better stealth than F22 & F35 if we use similar materials like of 22&35 .

Only time will tell how good it will be. Some people are disappointed that it doesn't look much fancy and immediately concluded it is not upto the mark , no words for those .

It is not detailed design.

Most probably, the design shown by DRDO cheifs presentation is the final iteration and it will be showcased in Aero India 2021.

Regarding the air intakes you are not correct. The F-22 uses F-15 style movable ramps for shock generation unlike the DSI of F-35 and J-20 which doesn't have any moving parts and is simple.

F-22 uses such a ramp structure with diverter plates and intakes because of its higher top speed . DSI are simpler ,weigh less and doesn't need a lot of maintainance . That's why Su-57 used ramps in the inlet instead of dsi because it also has a Mach 2.0+ max speed and higher supercruise speed. When you need that extra performance you need to focus on the minor details . And Su-57 isn't what most Western fanboys and F-22 and F-35 experts allege it to be .

DSI offers you mediocre performance at higher speeds unlike the variable ramps. It's all about what you want your ac to do and the tradeoffs required to accomplish the same.

Here's some high quality snaps from the video.

I love the new dsi intakes.

No auxiliary weapons bays are present .

Air intake and the side view of J-20.

The intakes and side view of an earlier iteration . They both are almost similar if we consider the newer variant with the diverteless si. But our intakes are stealthier due to the absence of that voluminous bulge .

What you must have meant was the ventral belly where in our Amca has a smooth flat belly tight upto the engine bay whereas the ventral portion of J-20 especially at the aft section are contoured and curvy . In this regard, our Amca is even better than the F-35 which has some bumps and curves here and there underneath .

QRSAM is a short range SAM system while StarStreak is a MANPADS.

Yes..Starstreak is VSHORAD

Agreed here. For higher kinematic performance a ramp structure is best. Unless you tune your DSI to work best at that high speed, in which case your DSI will impede low speed performance. Its all about tradeoffs. IMO the IAF wants the AMCA to be supermaneouverable at subsonic WVR combat and have decent suprecruise speeds in the range of 1.2M-1.4M, for which this DSI is optimized. At the top end this plane will do 1.8M. The design philosophy is akin to a stealthy Rafale. Strong multi-role characteristics with stealth and affordability. If at all we go for an Advanced Heavy Combat Aircraft in the F-22 or Su-57 class, we should expect ramps. One word on the Su-57: Its primarily designed to catch the F-22 in WVR combat and defeat it in that regiment. Hence its stealth shaping is more at the front and is ignored from other dimensions.
