Discussion Overview

The discussion revolves around the failure of the Prithvi-II missile to take off during a user trial, focusing on the implications of the nosecone detaching at low altitude and the potential reasons behind this event. Participants explore the nature of the missile, its components, and the possible presence of payloads or instrumentation.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants suggest that the nosecone detaching at low altitude is likely due to the presence of an expensive payload that should not be lost in the event of a failure.
  • Others propose that the detachment might be part of a launch abort system designed to jettison the capsule for recovery during a launch failure.
  • There is a discussion about the nature of the Prithvi-II missile, with some noting that it is a ballistic nuclear missile, raising questions about the purpose of the nosecone in this context.
  • Some participants express uncertainty about the missile's configuration, suggesting that it could be carrying an instrumentation package rather than a warhead during the test.
  • One participant mentions the potential value of the guidance system, implying that it is a significant asset that would need to be preserved.
  • Clarifications are made regarding the missile's classification, with one participant noting that it is not an ICBM but a theater missile with a specific payload capacity and range.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the reasons for the nosecone detachment or the nature of the payload. Multiple competing views remain regarding the missile's configuration and purpose.

Contextual Notes

There are unresolved assumptions about the missile's design and the implications of the nosecone's detachment, as well as the specific nature of the payload involved in the test.

why is nosecone detaching at such a low altitude

most likely that is where the expensive payload is - and they don't want that going kaboom with the rest of the rocket! :biggrin:
 
If I recall correctly, it's a launch abort system that jettisons the capsule for recovery in the event of launch failure.

Hmmm, that's sort of odd in my opinion...seeing that Prithvi II is a freakin' ballistic nuclear missile. That nose-cone thingy would be the nuclear warhead. :confused:
 
Wasn't sure what kind of rocket it was; just trying to give a general answer (goes to show what happens when you make assumptions). That would be rather odd for a ballistic missile to have such a mechanism.

Perhaps for the test it's some kind of instrumentation package? (I'd certainly hope they didn't have a warhead onboard!)

You're probably right about that. Probably didn't want to lose their telemetry gear :).
 
I can imagine the guidance system (if its in there), is not cheap.
 
It's not an ICBM. It's a theater missile capable of a 1,000 kg warhead. The Prithvi II range is just 350 km. Whether that warhead is nuclear or something else is up to India, though there are far cheaper ways of delivering 1,000 kg payloads...

It's principle advantage, courtesy of its significantly-sized wings, is it's ability to defeat anti-ballistic missiles.
