What's PJ-10 (WCx) and (MS)?

 

[Dessert Storm]

can anyone help me out.
what's our counter measure against emb if used by PAF or chinese ?????????

Countermeasures

Faraday’s caging and metal encasing of systems and components is considered to be the most effective protection against EMP, besides physically destroying the weapon delivery platform itself.17 These are designed to divert and soak up the EMP. Additionally, electrical surge protection circuits and terrain masking could be useful. However, the costs of building EMP protected military systems or EMP hardening of all current systems is considered proh ..

What's PJ-10 (WCx) and (MS)?

Launchers for Brahmos Cruise Missile
Government of India and Russia has entered into a joint venture for development of a Supersonic Long Range Anti Ship Cruise Missile system. DRDO & NPOM, Moscow are the development agencies. Programme PJ-10 is the DRDO part of the joint venture. The Programme started off with signing of contracts with Joint Venture company named as “BrahMos”. Platform Systems Work Centre: R&DE (Engrs), Pune has been made a nodal agency for the development of Launcher & ground systems for BrahMos missile. The Platform Systems Work Centre includes design of various kinds of Launcher & Ground systems equipments for both demonstration launches as well as launch from land & ship platforms.

What is indigenous in Brahmos

Brahmos is designated pj 10 not sure what the rest means

A new digital rwr is in development..
It is going to be tested in test rig for 18 months....
Then it will be tested with LCA Tejas.......
Intially it is being developed for LCA Tejas...
Later it will be integrated with su30 ,mig ,and lch...too

Is this the Dhruti rwr you are talking about? Because this digital RWR was first shown at Aero India 2017. According to folks from DARE in Aero India 2019 AFAIK trials were already ongoing and the rwr was to receive certification soon.

I knew DR118 has already entered active operational service onboard the MiG-29UPG and Su-30MKI fleets .The conversion from the analogue Tarang mk2/3 to Dhruti has already begun.

 

[Arihant Roy]

More on the Dhruti DR118. This system has been around for quite some time.

I reckon, only it's integration on the Tejas fleet is pending.

 

[Arihant Roy]

The MKI fleet is now being retrofitted with a six antenna RWR config for mask free 360 degree spherical coverage.

Outfitting work is progressing at a rapid pace on Drdo's Technology Demonstration vessel.

Why do DRDO and Navy have to use such science project/ tech prototype sort of names for projects such as these ? Advanced Technology vessel , Technology Demonstration vehicle .. in these day and age do they expect to hide these type of high priority strategic projects through such academic sounding names ?

Can an LPD be designed based on this platform? Like the Jalashwa?

Missile tracking ship will be a better option for LPD. It has over 10,000 tons displacement.

What is the difference between pump jet propulsion and normal blade propulsion

Give more stealth by reducing cavitation,you know those bubbles which are formed due to pressure difference.
That's primary.
And protection from environmental problems you know when you enter harbor there are chances of some unwanted hit.
Also, you can vector it and it has higher power density if I am not wrong.

What is the difference between pump jet propulsion and normal blade propulsion

Pumpjet offer's better speed with less noise compared to propeller. It has better efficiency than propeller . And the blades get better protection . It can be fitted with Thrust Vectoring for better manuverablity.

Disadvantage is it is more complex and heavy so it may not be suitable for small Submarines

It may be more complex to manufacture, but more reliable and easy to maintain. Torpedoes use pumpjet propulsion too, so how can it not be suitable for small submarine.

DRDO definitely ain't short on names. Agni, Prithvi, Prahaar, Pralay, Surya, Swati, Rajendra, Himshakti, Nag etc. You would know, the compendium of Indian Names would be running into lakhs. We should not be complaining about names. Let them be. They would be having a reason to name it the way it is or maybe they are calling a spade, a spade.

I wasn't talking of missiles or tanks or other platforms.

I was specifically talking about the Pmo administered strategic projects . Am also not complaining about the names. They can be anything just as long as they are delivered on time and functions flawlessly.

Your initial post.

Hmmm.... surely you were not.
Your counterpoint

Then what was your initial post about, if you were ok with the names?
