India to test-fire 3,500 km range K-4 nuclear missile
To further strengthen its capabilities of hitting enemy targets from submarines, India is planning to test-fire the 3,500 kilometre strike-range K-4 nuclear missile from an underwater platform off the coast of Andhra Pradesh on Friday. The missile system is being developed by the DRDO for the Arihant class nuclear submarines which are being built by India. These submarines would be the mainstay of India’s nuclear triad. “As per plans, the DRDO will carry out test-firing of the K-4 nuclear missile from an underwater platform off the Vishakhapatnam coast on Friday. During the trial, the DRDO will test the advanced systems in the missile system,” government sources said in Bhubaneswar. K-4 is one of the two underwater missiles that are being developed. The other one is the over 700 kilometre strike range BO-5 missile. It is not yet clear whether the DRDO will test the missile at the full strike range or shorter ranges. However, NOTAM (Notice to Airmen) and marine warnings for long-range missile test have already been issued by India for the planned test-firings. The K-4 missile test was planned for last month but was postponed. DRDO also plans test-firing of the Agni-3 and BrahMos missiles in the coming few weeks. Government sources clarified that the test-firing of the K-4 would be done from an underwater pontoon as the missile is still being tested and launch from a submarine would only be done once it is ready for deployment.

Any news of the missile test results which are in progress?

 

[learn from failures]

Any news? K4 missile was supposed to be tested yesterday.... any update?

It's stormy condition here in WB and Odisha. So forget about any tests..

 

[Hari Sud]

Did the K4 test finally take place or stormy weather in Bay Of Bengal prevented it.

I think govt is deliberately putting out fake Notams and not bothering to cancel it. This way snoopers never really know if a notam is actionable or not and it is hard to position resources everytime a notam is issued moreover it opens them up to detection too.

India conducts first night trial of Agni-II missile
India on Saturday successfully conducted the first night trial of nuclear-capable intermediate range ballistic missile Agni-II from the Abdul Kalam Island off the Odisha coast.

India on Saturday successfully conducted the first night trial of nuclear-capable intermediate range ballistic missile Agni-II from the Abdul Kalam Island off the Odisha coast.

The Strategic Forces Command of the Indian Army test-fired the versatile surface-to-surface medium-range nuclear-capable missile from launching complex IV of the Integrated Test Range on Saturday evening, defence sources said.

Developed by the Defence Research and Development Organisation (DRDO), the missile has already been inducted into the armed forces.

The 20-metre-long, two-stage ballistic missile has a strike range of 2,000 km. It has a launch weight of 17 tonnes and can carry a payload of 1,000 kg, the sources said.

Interesting! The K4 test turned into a A2 test. I wonder what happened to the K4 test.

Who tells you that all a missile test need it putting out a NOTAM? India itself need to do a lots of preparations, such as sending out her own survilliance ships to watch the whole journey. These preparations can't be hide and cost a lot.

Seems too much pressure on K4 test from USA.... hope we don't succumb to it....

 

[captscooby81]

No Agni 2 was slated for testing on nov 16th and it happened on the same date . K4 was planned for Nov 8 and the cyclone in BoB made the launch cancellation.

So there is still a chance of K4 test being conducted in this month

A2 was tested for 740 km range, yesterday test was the first successful night trail of A2. the previous one in 2009 was a failure.

Yeah but the adversary won't know it is a fake NOTAM unless they position their resources to check if we are making preparations.

K4 couldn’t have happened because there was cyclone during the notified days and immediately after that US triservices HADR exercises are underway near Vizag...

Americans have come with a ship,who knows what equipment is on that ship.

Come on man.. K-4 has already undergone several tests earlier...

Interesting that the missiles have night and day trials

Interesting that the missiles have night and day trials

What is the significance of night trial?

 

[Shashank Nayak]

What is the significance of night trial?

Read somewhere a long time ago ... that as the composition of the atmosphere at various altitudes differs (day as compared to night)... test launches are conducted during the day as well as night.

 

[Jameson Emoni]

What is the significance of night trial?

For a ballistic missile, it absolutely makes no difference whether the missile is fired at nigh or day. The target acquisition is based on the velocity, the altitude and the angle. For a cruise missile, night and day may make a difference as they use photo sensing technologies; I am not sure though. May be @captscooby81 can elaborate further on this.

Let me tell you guys something incase you all are not aware of

Missiles launched for tests contain TELEMETRY packages along with onboard sensors which generates and collects onboard systems specific real time data and relays the same over the entire period of flight.

And this is where the problem lies

Foreign intelligence assets / sensors try to pick it up for analysis and building up the database on the characteristics and performance of the missile in question .

Americans have 3 dedicated land based SIGINT stations in Thailand targetting Indian missile tests.

Chinese have 1 dedicated land based station in Myanmar.

Aerial and sea borne platforms are employed too

In the past Americans had already isolated and extracted the information channel of the telemetry and related comms signals from the carrier channels and then even broke the encryption.

But india after some period of time somehow managed to learn that their comm channels have been successfully compromised .

Later new techniques to hide the channels , new harder to catch transmission techniques and more robust encryption techniques were used which included simultaneously developing domestic software and hardware ( hardest part to fructify )

So any kind of obscuration that takes place during tests or after NOTAMs are filed the main purpose is deter the snooper from getting hold of the telemetry signals being beamed from the missile during flight.

As being claimed in posts above, tracking the physical movement of missile by snoopers is not a big deal , the big deal is getting hold of the telemetry data since it contains everything single event happening on the missile on a real time basis eg speed , acceleration , altitude , sequence of various control commands like for actuators , retro motors , RCS , stage separation , etc etc.

I hope you guys get the idea now

If we have successfully masked all the telemetry signals then physical snooping becomes all the more imperative. Positioning radars and trackers to track the missile in its entire flight envelope.
