Dude!!! I thought you went away!!! But you're back nagging about the same issue!!! Why don't you take your fight to
sayareakd - he agrees with the reality of Brahmos actually being a 600 km missile (he's also the moderator of this group, so I presume he knows something)!!
But it's my weakness never to let down a curious mind. So I'll indulge a little more (hope I don't regret this!!)
Firstly Brahmos was supposed to be a revised/improvement over Oniks; as such it's not a surprise that the parameters are slightly improved over Oniks!! Can you imagine a supposedly new 3 ton missile (just like the old Oniks) that actually flies only half the distance of the old missile and India paying 50% of the new development costs??? Even with your own quackery of F=md, half the range (with design improvements) should have resulted in loss of half the weight of Oniks (sounds logical??). As a reference, the new Brahmos-NG actually does travel only 290 kms and will weigh less than half of Brahmos/Oniks (ring a bell?).
If you're saying that the extended range of Brahmos needs a complete redesign, new engine etc, how come there is no new name for this brand new missile?? There's Brahmos-A for air launched one (even with minimal change - just got rid of the booster!!!), then there's Brahmos-NG that's been talked about for a while (the government has been dilly-dallying about sanctioning the project for a while!!). Even software changes et al created Block II, Block III etc. There's talk about 'project work' on Block IV. Can you tell me what the name of this brand new missile is? what is the budget for the missile development program? what is the project schedule (isn't it customary for the R&D folks to say that they'll have it ready in 2-5 years)? How many of the new missiles will be ordered (has it been projected yet?)?
All that Russians/Indians are saying is the Brahmos range will be extended - which is that the range of the existing missile will be extended!!!
The best thing for you to do is chill, wait for few months and you'll hear that the missiles have been range extended!! It'll be a nice surprise for you.
That still leaves my initial question unanswered: Will Brahmos-A also be range extended. Nobody's seems to know!!!
