Indigenous nuclear submarine to undergo missile firing tests

India's first indegenously developed nuclear submarine Arihant, which has "successfully" completed the sea trials held so far, will undergo its maiden missile firing test this month, top defence sources said.

The aim is to handover the submarine to the Indian Navy during the International Fleet Review scheduled in February next year in Vishakapatnam, they said.

"The tests held so far has been successful. We will, this month, fire Nirbhay missile from the submarine which will be followed by firing of another type of missile," the sources said.

While Nirbhay is a 1000-km-long range subsonic cruise missile, the next missile would be India's first Subamrine Launched Ballistic Missile (SLBM), which has a range of about 700 kms. These would be followed by another few rounds of tests.

India plans to build at least two more Arihant-class submarines. India had started building Arihant in the 1990s under its highly secretive ATV (Advanced Technology Vessel) programme.

Though Arihant was initially supposed to be a fast-attack submarine, the project was realingned to make it a ballistic missile submarine following the nuclear test conducted by India in 1998.

After its launch in 2009, Arihant went through extensive tests including harbour acceptance trials with the on-board reactor going critical in 2013. It left the harbour for its sea trials in December 2014.

We will, this month, fire Nirbhay missile from the submarine which will be followed by firing of another type of missile,

From Where Nirbhay would be launched? Will it fit the same tubes like K15 with 3 nirbhays in each tube?
IF not then is it going to be fired via Torpedo tubes?
In that case is it configured to fire from 533/633mm or its modified to 650mm like Israel modifications of DolphinII ?

Arihant armament

Arihant will be capable of carrying all types of missiles and will have underwater ballistic missile launch capability. It will carry 12 K-15 SLBMs that can be launched even under ice caps.

Tested in 2008, the K-15 missiles are 10.4m long and have a diameter of 1m. The 6.3t missiles can carry a 5t nuclear warhead targeted 750km away. The K-15 missiles, however, will be replaced later by the 3,500km range K-X missiles.

Apart from the K-15s, the submarine will carry a range of anti-ship and land-attack cruise missiles and torpedoes.

So first test would be of Nirbhay from arihant followed by K-15.

That means arihant class will be ssgn rather than ssbn.

Kyu bhai? Can't a SSBN fire a cruise missile? After all Arihant will have to go for all sort of test firings...from cruise missiles to ballistic missiles.

Sir ji, I am saying the same, will Nirbhay fit the same tubes like K15. K15 are fitting 3 in each tube in vertical launch configuration.. So i am asking is Nirbhay also similarly able to fit 3 in nos in each tube in the same configuration.

IF not, will it be fired from torpedo tubes same like popeye turbo in Dolphin II operated by Israel and made by France..

Nirbhay is just 0.52m in diameter with 6m length. implying its sleeker than K15


Look at the last figure, with diameter of 0.66m (bottom right 4th quadrant), 6+1(center) or even worst case scenario 6 missiles of diameter 0.66 m can be fitted in a single tube vs K15 diameter of 0.93m type 3 in nos (as shown in top left 1st quadrant)

Btw also it can be configured to fire from 533mm tube as its diameter is just 0.52m whichh Arihant is suppose to have 6 in numbers (6x533mm torpedo tubes)

i say each Arihant will carry
Tube Vertical config - 6-7 Nirbhays in each tube based on above diagram
Tube torpedo - Any number based on reload perhaps 6 SLCMs in single salvo mode before full reloads..

@Abingdonboy @Capt.Popeye @kurup @MilSpec @SpArK @AUSTERLITZ Can you help explain..
