    Bay of Bengal: After a smooth countdown at 1.40 pm today, India's missile, named BO5, emerged effortlessly breaking the balmy waters of the Bay of Bengal. The missile was launched from an approximate depth of about 50 metres, simulating exactly the conditions as would prevail during an operational launch from India's indigenously made nuclear-powered submarine bINS Arihant. The missile whose name has been variously given as Sagarika or at times K-15 or even Dhanush has finally been christened as BO5 and is a medium-range ballistic missile. After emerging from the water, the missile followed a copy book track of its trajectory and hit its target about six minutes after launch in a very precise manner. The trajectory was tracked using several cameras and radars specially deputed for this launch. This is the fourteenth consecutively successful launch of this potent weapons system which has till now always been done in complete secrecy. This was the last developmental launch and now the weapons system is ready to be integrated with the Indian submarines, says AK Chakrabarty, the man who designed and perfected this naval missile system and is also the director of the Defence Research and Development Laboratory, Hyderabad. He spoke exclusively to NDTV on board the ship which controls the missile launch. This sophisticated technology has been mastered only by the USA, Russia, France and China. India has now joined this select club of five, and has now completed what is called the nuclear triad, which essentially gives India the capability to launch at will its nuclear weapons from air, land and sea. The indigenously made missile has been perfected after more than 15 years of development by the Defence Research and Development Organisation (DRDO). Mr Chakrabarty, who had tears of joy in his eyes, described the mission as "perfect and could not have been any better." A young team of about 200 DRDO scientists and personnel from the Navy and a flotilla of ships took part in today's mission. The NDTV team of Pallava Bagla and Alphonse Raj were the only journalists allowed to witness the launch live from the middle of the Bay of Bengal.

    India test fires missile from under sea, completes nuclear triad

    What guidence system its using?
    For this one i guess 'strap down INS'. Hence more computational power and accuracy.

    India's DRDO today conducted the 11th successful underwater test of the K-15 medium range subsurface-launched ballistic missile from the Bay of Bengal. Sources on board one of the Indian Navy ships monitoring the launch report that the launch was a successful one. The launch took place from a special R-glass cannister from a specially configured underwater pontoon launch platform. The K-15, officially designated B-05, with a range in excess of 750-km (its official range is classified) is the submarine-launched version of the land-launched Shourya (see photo) that has been tested four times so far. The country's Arihant-class SSBNs will be able to deploy 12 K-15s or four of the much longer range K-4 missiles, still under development.

    So the test is confirmed to be K15 ..........:tup:

    This is the last test from submerged pontoon as announced from DRDO .

    So hopefully we can soon see K15 test from Arihant.

    Great news !! Seems India want the nuclear triad in hurry. Never thought that in 10-12 years after Pokhran-II we get the nuclear triad. Very impressive indeed.

    INS with Ring laser gyroscope, developed at RCI Hyderabad imo.

    Impossible ........K15 weighs 10 ton and can only be tested from a vertical silo which kilo lacks.

    Nope:


    It is Ring Laser Gyro (RLG)based inertial navigation system (INS) and the modern micro navigation system (MINS)

    In April 2007 India conducted the first of 14 tests of the Sagarika or BO5 (This one being the 14th). The DRDO has also test fired the K-15 from a land-based launcher from Orissa. The land based version is named as 'Shourya'.

    So how was the K-15 or Sagarika or BO5 tested without a submerged submarine? Here's the details of the launcher...

    Project BO5 Launcher

    [​IMG]


    The launcher was designed and developed for testing of missiles. The system was been mounted inside a pontoon. Design by analysis approach has been adopted for final configuration of the launcher. The material used for launcher structure is high-strength-low alloy (HSLA) steel. Sets of guide rails are bolted to the container to hold the launcher. Advanced fabrication technology has been used to ensure the desired perpendicularity, parallelism and concentricity. A 2.3 m static seal, which restricts water ingress to the bottom of the container, was designed and experimentally validated for extreme hydrostatic pressure.

    The platform launcher has been designed for launching medium range surface-to-surface missiles. It comprises a launcher structure, a set of shock isolation systems, a set of launcher locking mechanism, a set of special seals and a connector alignment mechanism for connector blind mating. The launcher structure has precision dimensional features for perfect interfacing with the missile and other subsystems. The structure is made of special high strength stainless steel for a maintenance-free service life. This material does not need any corrosion protection against any aggressive marine environment.

    The shock isolation systems protect the launcher against shock load. The shock isolation systems comprise disc spring stacks in longitudinal direction and elastic beams in lateral direction. This particular non-conventional combination takes care of compactness and mode decoupling. The locking mechanism locks the shock isolation suspension system and provides rigid support during launch operation. It is a fail-safe all mechanical device. The 2.4 m diameter diaphragm seal prevents water entrance and flexes when the launcher vibrates on the shock isolation mounts. The seal has been developed based on steel reinforced radial tire technology. The connector alignment mechanism has six degrees of freedom and, therefore, capable of taking care of any misalignment within the envisaged limit during blind mating of connector.

    (In early 2008 India announced that it had perfected the technology for launching missiles from a submerged submarine. That meant the silo design had been perfected as well).

    Cheers!

    Yes the srtrap down INS-
    This one has laser running insude optic fiber tubes...and sensors calculating phase change due to change in missile heading.. Then feeding data to a computer which calculates course correction accordingly...
    Both sensors and computer need to be compact and fast to do these calculations,and a well written software.
    Benifits over older gimball based INS (Still used in Ghauri) is that fluctuation in Gravity such as increase in gravity while on a mountain range,and mechanical friction does not effect the system's accuracy..as there are no moving parts.


    Btw...where will india fit Brahmos on their subs?
    The vertical launch tubes will cally Ballistic missiles and 500mm dia Nirbhay can be fired from standard 533mm torpedo tubes..
    Where will be the room for Brahmos?
