With the successful launch of a K-4 from the Arihant‘s on-board silo, India steps closer to its nuclear triad.

India’s Defense Research and Development Organization (DRDO) has once again test-fired the K-4 nuclear-capable submarine-launched ballistic missile (SLBM)–this time from aboard the Indian Navy’s indigenously built nuclear submarine, the INS Arihant, the first submarine in its class. According to press reports citing DRDO officials, the test was “highly successful” and involved a fully operationally configured K-4 with a dummy payload. In March 2016, DRDO had successfully tested the K-4 from a submerged platform in the Bay of Bengal; DRDO officials at the time declared the test to have been a “roaring success.”

According to the New Indian Express, the Arihant-based K-4 test was “conducted on March 31 nearly 45 nautical miles away from Vishakhapatnam coast in Andhra Pradesh.” The K-4 missile was fired from the Arihant‘s onboard SLBM silos.

India’s K-4 is an intermediate-range, nuclear-capable, submarine-launched ballistic missile. Though official details remain scarce given the project’s sensitivity, most estimates place the K-4′s range at roughly 3,500 kilometers. Recent testing of the K-4 has sought to test the full operational range of the missile. As my colleague Franz-Stefan Gady discussed in March, “the K-4 was only tested to a range of 3,000 kilometers” in previous testing. In addition to its range, recent testing as sought to test the SLBM’s accuracy. Claims by DRDO scientists and publicly available information on the system suggest that the K-4 is a highly accurate system. As Franz has discussed, DRDO scientists have boasted that the K-4 has “near zero circular error probability” and uses “a Ringer Laser Gyro Inertial navigation system.”

The K-4, along with the K-15 Sagarika SLBM, will give the Arihant-class of nuclear submarines their nuclear strike capabilities, allowing India to field an undersea nuclear deterrent capability. The K-15 has a considerably shorter range than the K-4. At a maximum strike range of approximately 750 kilometers, Arihant-class submarines would have to move close to enemy shores to successfully deploy the K-15 SLBMs, increasing the odds of detection. The intermediate-range K-4 helps rectify this shortcoming. The K-4 is capable of carrying both conventional and nuclear payloads in excess of 2,000 kilograms.

The Indian Navy anticipates commissioning the first Arihant-class submarine in 2016. The Indian Navy anticipates eventually fielding a force of three to six Arihant-class submarines. INS Aridhaman, in construction, will be the second submarine of the Arihant-class. Each submarine will be able to carry 12 K-5 Sagarika missiles and 4 K-4 SLBMs. With the Arihant‘s commissioning, the Indian Navy will join the navies of the United States, the United Kingdom, France, Russia, and China in operating nuclear-powered ballistic missile submarines.

K4 and Arihant are platforms which we hope that we never have to use, since their use would mean that a nuke has been dropped on Indian Soil

I am more interested in faster induction of SSKs , 6 scorpenes are simply not enough
We need 18 modern SSKs to have a capable underwater fleet
 
The K-4, an intermediate-range nuclear-capable submarine-launched ballistic missile with a purported range of up to 3,500 kilometers (2,174 miles), will be launched from a submerged pontoon, a replica of a submarine, from water 9 meters (around 30 feet) deep, according to DRDO sources.

The DRDO scientists’ purported aim this week is to test the full operational range of the missile. During a previous test in March 2014, where the weapon was ejected from the submerged pontoon by a powerful gas generator, the K-4 was only tested to a range of 3,000 kilometers (1,864 miles).

Technical details on the top-secret K-4 remain scarce. It purportedly is 12 meters (39 feet) long, weighs around 17 tons, can carry a nuclear capable warhead of up to 2 tons, and is powered by solid rocket propellants.

DRDO scientists claim that the missile is highly accurate with a near zero circular error probability. According to publicly available information, the K-4 uses a Ringer Laser Gyro Inertial navigation system.

The missile, capable of cruising at hypersonic speed, also features an “innovative” system of weaving in three dimensions during flight as it approaches its target. The New India Express paraphrases a DRDO scientist saying that this “exceptional feature of the weapon system makes it difficult to be tracked easily and destroyed by any anti-ballistic missile defense systems.”

The K-4 will undergo two more development tests before it will be fired from the Indian Navy’s first indigenously developed ballistic missile nuclear submarine (SSBN), the INS Arihant.

The submarine is equipped with four vertical launch tubes, which can be armed with either four K-4 missiles or 12—three per launch tube—K-15 missiles, another member of the K-series of missiles with a maximum range of 750 kilometers (466 miles).

There have also been some reports that DRDO is also working on a new top-secret variant of the K-4 with a 5,000 kilometer (3,106 miles) range.

India’s nuclear warfare policy is centered on a No First-Use (NFU) doctrine. The K family of missiles is meant to boost India’s second strike capability and will be the cornerstone of the sea leg of the country’s nuclear triad. India still maintains a policy of keeping its nuclear warheads de-mated from the missiles.

One of the major problems for India remains that its submarine force is too noisy, calling into question the credibility of its second-strike capability even with the new K-4 missile. Loud submarines are more easily detected and can be quickly neutralized in the event of war.
 
its not K4 test

Its K15 test

Even with depressed trajectory or lofted trajectory, it cannot be going for 20 percent range at full payload ...

Logic says it has to be minimum 1/3rd so a K4 test will be confirmed only when the so called range is over 1100-1200 km for a SLBM

so its a wrong reporting..
 
What's the hold up for Arihant now ? IMO induction in this month or next.
 
What is the status on Aridhaman? Can't wait.
First thing don't believe in "The New Indian Express" website as it spreads propaganda against our defense Establishment. Now coming on your query, Arihant will be commissioned, Aridhman will be launched for trials and third boat will be moved to fitting shortly Arihant is doing last minute testing, Aridhman checking it's parameters for trials, and third boat waiting for Aridhman to move out. Two three points crucial worth mentioning Arihant test dummy flight ejection upto 6 times in recent weeks, third boat hull fabrication completed.

What's the hold up for Arihant now ? IMO induction in this month or next.
Maybe by before monsoon season.
 
two test has been conducted

A) 7th March
B) 31st March

India Conducts Twin Secret Tests Of K-4 SLBM by Livefist.
 
India Today can confirm that India has successfully tested its most ambitious weapon system -- a long range submarine-launched ballistic missile, codenamed K-4, capable of can strike targets upto 3,500 kilometres away. The missile test is being seen as a huge step forward for country's nuclear weapons programme and strategic deterrent.

India Today has accessed the first images of this secretive weapon system that has almost never been seen before in flight. The missile system was tested twice in March from India's home-built Arihant ballistic missile submarine, a platform that's currently undergoing sea trials before a possible entry into service next year.

The K-4, a derivative of the more well known Agni ballistic nuclear missiles already in service, will be the most potent part of India's nuclear deterrent.

The missile, which has now taken a steady step forward to prove itself, will arm India's nuclear ballistic missile submarines, invisible and undetected until they need to be used.

The missile, which has developed by the Defence Research and Development Organisation (DRDO), can carry a warhead weighing upto 2,000 kg. The DRDO plans to develop three missiles K-series missiles.
