May be, I am asking something stupid. But is there a single stage missile in our arsenal with a 2500 km range?

wouldn't that be highly inefficient? Carrying all that dead weight when not needed?

No. Its terribly inefficient to build such a missile.
However Iran, NoKo, PRC all have such liquid fuel missiles.
Shaab, NoDong, CSS4 etc.
Pakis call their version Ghauri.

I understand that it is inefficient. Then why do we have a continuous region in the NOTAM for the 2500 km tests

And a separated region in the NOTAM for the 2500 km tests

Second one or 19 - 21 launch window is for F/S to splash down.
The first one could be special case.

BREAKING: After delays, India today tested the K-4 submarine launched ballistic missile (SLBM) from off the east coast. Will arm India’s Arihant-class submarines.

2500 Notam talks about "multiple experimental test vehicles".

Testing of MIRV?

I guess the test happened from a pontoon rather than sub since the missile is still in active development. Will be more happy if the missile was sub-launched. But one step at a time is fine...

If it was development test from a pantoon, DRDO will not test if from andhra. It will be from orrisa. There is no test center in andhra.

Pontoon launches also happen from Vizag coast only not Kalam Island

BTW if the launch is so close from Vizag, are there any civilians recording videos of the launch, it should be visible (and heard) from 10s of kilometers away. Surely someone would have noticed and pointed their phone cameras at it?

Chindu, confirming the same but NOTAM suggest multiple maal wala package. I like the term used Experimental test vehicle

Here is the video url , not sure if its old one or current test one :

K-4 was successfully flight tested on 24 Mar 2014 from a pontoon submerged 30m deep in the Bay of Bengal, off Vishakapatnam coast. On September 23, 2015, DRDO scientists associated with K-4 from DRDL, Hyderabad were presented with a special award for its design & development. The test of March 7, 2016 was termed as a phenomenal success as it validated a few technologies. Thus, two K4 tests had been done without any announcement. This is at least the third test.

Sandeep Unnithan wrote once that nearly 10 tests were conducted, most of them without announcement. Wiki itself lists a handful.

Most of them were successful, with a couple of failures. One was an aborted launch due to a drained battery. Another (which was hinted indirectly in reports today) had to do with a "tilting problem" that was solved - once the missile exits the water.

Wouldn't be surprised if at least 1 or 2 tests were from Arihant.

K4 seems to have the ability to follow a non-ballistic glide path, viz. hypersonic maneuvering in 3D, alongwith high accuracy to defeat ABM. Maybe the latest "experimental vehicles" are to validate some of these technologies. Or MIRV/MaRV. God alone knows!

How tests can be conducted without NOTAM? Most likely those were to test launch from under water.

I think under the name of Prithvi we have tested all other missiles too. The liquid fuelled Prithvi may be on its way out or kept in reserves

My favorite are the Lakshya drone tests. During its entire testing over years, those damn things must have traveled enough distance. From all the way to Oort cloud and back. It is not often that a significant chunk of a journalist's entire career is about reporting a target drone's daily routine

We once had a 200 meter diameter Prithvi tested as per reports.

While some validation tests could have been done as 'Prithvi test' how would the range be validated?

^^^ all the new stuff that needs validation is initial launch system and first stage. All that cab fitted into Prithvi range. You need a whole lot of tests thete.

Full system test fitted into Agni1/2 test : lofted / depressed trajectory

Why do you say this? The test was conducted after NOTAM was issued.
Pontoon launches to proof the under water launch do not require NOTAM as they are just pop up and splash down mostly.
However to brag and to create an atmosphere of mistrust people confuse the issue and help NPA.

And folks talking about other launches are doing no favors to DRDO.
There are dummy launches which don't require NOTAM.
There are full range tests that require NOTAM and are given.

To all those saying this is a pontoon test, why would you pontoon test a missile? Its already qualified for UWL.

I don't know anymore but just asking those who confidently post.

Anything that concerns airmen, must be notified. Especially if can intersect the level at which commercial flights take place. A missile popping up from below to space and then back constitutes a serious issue that a flight captain would like to know about.

Agreed who is disagreeing.
A pop up test from the pontoon does no require NOTAM as it does not reach altitude.
In UWL the pop up is the crucial concept that needs proofing.
BTW it does not have to be hot fire to test the electronics.
But our chateratti all these are tests.
yes but not hot fire tests.

And 90% of missile tests are ground tests.
The other 10% are system tests.

Another test coming up on Thursday ..may be yesterday’s test was precursor to test from INS Arihant. They need to be absolute sure before staking a ₹10,000 crores submarine.

”The test was conducted from a submerged pontoon and has met the desired parameters. A pontoon simulates the situation of a launch from a submarine,” an official source said on condition on anonymity.

Air Force’s LCA to get Astra firepower, not Rafale’s meteor

The LCA will not bear Meteor — beyond visual range air-to-air missile (BVRAAM) — that is standard on the Rafale fighter jets, with the French side expressing its reluctance to integrate the weapon with an aircraft equipped with an Israeli-origin radar and the Air Force determined to bring down the heavy imports bill by selecting a home-grown option.

“We are not even looking at the French option. We want to promote the indigenous system and have it equipped across all our platforms. The Astra development programme has been satisfactory,” a top official said.

Sources said after the missile is inducted into the Su30MKI fighter jets from which it has been tested, the system would be integrated on other foreign-origin combat aircraft. The performance of the Astra, sources said, is regarded to be better than similar Russian systems currently in service.

Meteor was never going to go on LCA. There were just a bunch of lifafa articles promoting it. Lokos like they now realised the futility in dishing out payments to journos on this matter.

+1, IMO SLBM is more important than Agni 6. K4 has 3500 range with 2 tonnes payload, 1 tonne means it can go 7000 KM. We need a 10,000 wala for our 13T SSBNs. There is no bigger deterrent than SLBMs.

Does this logic really work? What distance would missile travel for 0.5 tonne payload in that case ?

There is no 0.5 tonne payload. So the exercise is academic.
Please look at Agni tests to get idea of the payload.

Sir, many moons ago in your previous avatar, you always maintained that unless the maal is not retested, it will always be FBF boosted device than pure thermo... Now, you being at peace of mind, does it signify any break through?...pls dont answer if not in national interest...thanks...

Is the test from a pontoon or from Arihant ? I suppose there will be additional complexities when firing from SLBM
