Nirbhay Family of Subsonic Cruise Missiles : News and Discussions

From the RCS reduction pov, the flush air intake certainly helps. Even the TLAM has adopted it in its latest version. But for a missile that's entering service in the 2028-30, ADA should have put in a nose chine at least.

We may never go for full-blown shaping like JASSM-ER or Kh-101, but minimal passive stealth features are a must these days.

We are already working on a stealthy air launched cruise missile.

You first need to have a stable proven article all qa qualified that is ground launched. Then from that base, you build the air launched version. Then you do airframe design optimisation and make a suitable stealthy design of choice. All the dev work go step by step like how Brahmos happened.

Quick question. Given that Rudram family missiles use LIDAR for terrain mapping/midcourse navigation, any chance Nirbhay/LRLACM might feature it too?

What are the relative advantages over radar altimeter? Also any news of LRLACM featuring chaff/flare/ESM for evading enemy air defences? TIA.

I don't know. I have seen radar altimeter is used but exact spec or what else is inside I do not know.

How lidar will work in foggy/cloudy environment?


What Nirbhay really need is magnetic contour mapping, i don't think that it has this feature (may be i am wrong too) to navigate properly over ocean when no GPS signals available /denied.

Magnetometers have been used for tracking in-flight missiles (telemetry) and satellites use them too afaik. Not sure about navigation though.

Took a bit of searching but here a couple of interesting tidbits on the use of laser altimeters in A-1P and Rudram missiles.

Specifically relating to Rudram:

This means our new-gen BMs and CMs have TERCOM, dual INS (RLG+MEMS) to fall back on in case of GPS/IRNSS jamming.

Where did you get ideas about LIDAR?
 
Brahmos Aerospace currently produces 12 Manik engines/year. The production capacity can scale up to 200 engines/year with the current infrastructure:
