Yes capable. It was quite a challange to fit the small special pkg, in the small cone with hot compressed engine air flow ducts around. The thermal load budget is v significant. I believe a nabhakiya aayudh of ~10kt.
Note that designed & test <> operationalized.

What is operationalized is conventional only to make it a everyday use weapon by field commamders.

Getting nervous- will the test take place due to weather? will the test be successful? All things a Jingo suffers from

I am just amused at the fact that the phoren trackers are doing a run around for nothing when these missile launches are announced and then cancelled.

Yes I am worried too about the trackers, especially during dangerous events like cyclones or even beeeeg waves. The Indian coast guard should keep checking on them twice a day and may be towing inwards for safe harbour. If you can't disturb the trackers at least keep checking well for goodness sake, may be share a bottle of wine.

The cyclone passed some 200 km east of Vizag. Areas close to Vizag do not seem to have had high winds/rain on Nov. 8. In any case, no news of any K-4 test has come soon after that test (except maybe for the first time in 2014). The only other news of a K-4 test was in 2016, when Hemant Rout wrote something about it a week later. But the NOTAM for that test was only for 700 km. Could it be that the K-4 was only tested once ?

Nice! Does this mean that the cyclone/heavy monsoon problems are over, and both DRDO and ISRO can now proceed with their programmes right away? ISRO's launch of Cartosat-3, and DRDO's testing were delayed overwhelmingly because of the storm issue, weren't they?

Right now is monsoon period of the eastern coast, no weather system today doesn't mean that it wont form or monsoon is over. Monsoon is decrease from mid December. New system is expected soon

This news item seems to indicate that the K-4 was indeed successfully tested on Nov 8. Do not know how reliable it is.

So will all future strategic missile tests be announced only on regional news channels like Loksatta and Kanak News?

Wat abt " Star of Mysore", hainji ?

Interesting. The picture is that of US Trident D-5.

No matter K-4 total tested 5 times per that report.

In the 1950s night testing was preferred for the possibility of observing the flame and hence rocket motor performance. Added bonus was to observe the reentry against the dark sky.
Even now the standard practice is to observe the reentry against the night sky.

why would we want to see the flame and rocket motor perofrmance now. This missile has been in development and operation for long. Unless of course we are indegenizing more components. I think there are two possibilities
1. Giving our opponents less chances to observe
2. Honing of night attack capabilities. Pakistan is largely night blind. Apart from US and Russia and may be china who else can keep track of a vast swathe of IOR over night time? Perhaps to avoid the tracking of Rail road launchers at night time to avoid a preemptive strike.

A 2000 km range class missile tested to 740 km means the missile was tested in high loft trajectory.
Pakis should be worried sick that a 1 tonne payload vehicle is tested to an accuracy of few meters and they are within the range even if they hide assets with Taliban.
In WOF Kalam saab was happy that Prithvi achieved 50m CEP with 1 tonne payload and said many targets can be at risk with that combination.

Now its even better.

Confident of doubling range of the Astra, will be the most lethal air to air missile: DRDO Chief
https://economictimes.indiatimes.com/ne ... 120351.cms

-We are very confident of extending the range to nearly double of its existing range, making it the most lethal BVR missile.
-All essential technologies required for BMD, like propulsion system, sensors, precision control systems and terminal intercept technology with kill vehicle development have matured and have been proven through various tests.
-Development of Agni Series of missiles has been completed and are in the process of induction

Doubling the range looks like ramjet though I'd have put my money all these days on a dual-pulse system.

The dual pulse probably won't double the range though? It might improve the NEZ and the range by 10-15% right?

Possibly the SFDR technology demonstrator phase transitioning into an actual program to develop an Astra Mk2?

Earlier, DRDO has certainly spoken of both dual-pulse and ramjet for ASTRA. Astra Mk. II was supposed use a dual-pulse rocket motor with smokeless HTPB propellant to enhance the range. A smokeless, non-metallized, high specific impulse solid motor had also been realized for Astra. Ramjet Propulsion for greater range and enhanced kinematics performance for a newer variant was spoken of making its debut beyond 2020.

IMO, dual-pulse must have been already realized.

A half-baked interview. No follow on questions that dig deep into the topic. Typical DDM.

We can interpret Dr. Satheesh Reddy words any way we want. We can even interpret it to mean that Agni-V is inducted!

Even though he didn't say so explicitly, I got the impression that he meant a doubling of Astra range without going down the SDFR route. SDFR a different class of missile and might not even be called Astra

Looking at the Chin military parade yet again, the number of ICBMs, and other assorted strategic missiles displayed in the dozens poses a huge challenge to us.Some of these shorter range missiles stationed in Tibet could strike any part of the subcontinent. We on the other hand have to develop longer ranged strat. missiles in sufficient second strike number to counter the Chinese. We also need a strategic bomber at least for the IN doubling up as a maritime strike bird.

The media reported today that the Sulur base is being earmarkef for being turned into a major munitions base
as well for the whole south, where various types of missiles, etc. would be stored.700 acres at least with a second runway as part of the plan.

Apart from the need for a manned/ unmanned deep strike bomber, the prime requirement of building the SSBN fleet with a genuine ICBM range SLBM is a must. The same missile could be modified for mobile launchers on land.. Needless to say the numbers of such missiles required to prevent a Chin surprise nuclear strike is a matter for the planners to formulate. The survivability of the triad is essential to achieve the desired objective.Pak is easier to strike at but equally more difficult to defend given the very short reaction time.

Israelis managed to pull it off with dual-pulse.
Derby —> 50km
I-Derby-ER —> 100km

However, they did create more internal space for propulsion by miniaturizing the seeker and associated parts. Two decades to do that.

Given Astra MK.1 is already a 100km missile and with lesser scope of compacting its new indigenous seeker, dual-pulse system applied to the same propulsion space constraints would probably mean only marginal range improvements but with better NEZ end game kinematics throughout.

IIRC, there was this novel "2017: writing on the wall" author mentioned some place (called the FARM) in Chambal area. That makes sense. Secondly China,Russia and USA has similar facilities to assure MAD.

I note ASRAAM seeker specs are:

substrate Indium Antimonide
Band 0.5 to 5.4 mu
Cooling gas cooled Joules Thompson refrigerator

Nag seeker specs are:
IIR 320x256 FPA
Substrate InAs
Band?
Cooling?

Yep I too think that will be the case until they introduce SFDR (Solid fuel ducted Ramjet) tech into Astra future variant.

Rafael 2 decades after introducing Derby missile in the mid 90s in 2015 introduced I-Derby-ER to the world. It's seeker is derived from Software Defined Active Radar seeker developed for Tamir missile used in Iron dome system.

A2a missile seekers are in NIR and MWIR bands. NAG seeker is LWIR. Cooling in nag is through stored on board pressurised coolant as well.
