Very Interesting radome.

The Non-Destructive Testing (NDT) for the Ti & other super alloys is definately for aerospace applications. The >400mm ingots could be for large shafts like those used on the main rotor of helos &/or propeller shafts of ships.
Very Interesting radome.

Why does Nose tip looks optically Transparent.
315 mm dia at the intersection. That's the Rudram-1/NG-ARM missiles' radome. Here is another look at it:

Many ceramic radomes use a nose tip that is of a greater mechanical rigidity than the radome's ceramic material. In the case of the NG-ARM we know the material is crystallized silica ( likely alpha-quartz). Silica has excellent electrical properties for the radome application, but it has very poor mechanical strength. Without a re-inforcement the radome is susceptible to breakage at hypersonic flight regimes.

Therefore a metal or dense crystal tip is added with a metallic wire frame to add to the mechanical strength. The frame remains hidden inside the radome where as the nose tip is visible. Here is the Astra's radome, notice the tip.

Even Navy designs are not indigenous in that sense as almost 60% subsystem including engines and main radar, CIWS etc all are foreign designs.
Still they give us huge advantage to choose whatever best available in international markets and even our own subsystems if nothing suitable is available like CMS,Sonar and other sensor systems, torpedo and other ammunition etc.
It’s not perfect but not bad either.

The quality of videos produced by the DRDO doesn't need better better production standards , it needs a complete overhaul beginning with firing of those involved in the making of such videos & I don't mean only the production staff here but those within the DRDO who commissioned the entire program.

What exactly have we learned from the video ? That the SAAW can penetrate some sheltered unit . Do we know the build quality of the structure ? Negative. Do we see any massive damage inflicted in the interiors upon penetration ? Negative. What exactly is the message we're sending out to our enemies or even the amateur defence enthusiast here ?

Previously we had the video of the VL SRSAM posted here . The whole damn video lasted a few seconds focusing only on the initial stage of the launch not the actual engagement & that too was completely off focus.

We just haven't learnt the art of propoganda & Balakote isn't where it began or ended . It was merely another damn episode in the unnecessarily steep learning curve of our security management & by the looks of it they haven't learnt a thing.

1 squadron will Not be enough

We have to contend with BARCAPS

Some hardened shelters will require Repeated attacks or SPICE bombs

By the way Sargodha is more than 150 KM away

You know more important than SAAW is RUDRAM Series of ARMs

Once Ground Radars and SAMs are dead , PAF becomes blind

And till RUDRAM is inducted , Air Launched BRAHMOS will be used for SEAD and DEAD missions

Hardened Air Shelters will need SPICE

SAAW is for Runways , SAMs and Radars

SAAW is a single class of bomb (120Kg), whereas SPICE is a family of three classes of bombs. SAAW easily replaces one of those classes. We have other bombs that replace SPICE too, like Gautham (1000Kg) and Gaurav (550Kg).
