BREAKING: DRDO test fires cruise missile Nirbhay from a defence range off Odisha coast.

Posting an old but informative article about Nirbhay

Nirbhay Cruise Missile Family Finally Revealed!

CM-2.jpg

The topmost schematic shows the 1,200km-range subsonic Nirbhay nuclear-armed cruise missile, which will be available in both air-launched and submarine-launched versions. The ALCM version (minus the solid-rocket booster) will be qualified for use by 20 specially customised Su-30MKIs, while the SLCM variant (incorporating the solid-rocket booster) will go on board the S-2, S-3 and S-4 SSBNs. The air-launched and nuclear-armed Nirbhay will have an estimated length of 6 metres, diameter of 0.55 metres, wingspan of 2.7 metres, launch mass of 1,200kg, cruise speed of Mach 0.7, and a 250kg warhead-section. Its cruising altitude over water will be 10 metres (33 feet), while its cruising altitude over land will be 30 metres (98 feet). The MoD-owned Hindustan Aeronautics Ltd’s (HAL) Bengaluru-based Engine Test Bed Research & Development Centre (ETBRDC) has developed a turbofan (see below) for powering all members of the Nirbhay cruise missile family.

A hybrid inertial navigation system using a ring-laser gyro (RINS) coupled with a GPS receiver and a digital radar altimeter (all developed by the DRDO’s Research centre Imarat, or RCI, and integrated jointly by the Advanced Systems Laboratory, or ASL, and the Aeronautical Development Establishment, or ADE) will provide a CEP of 20 metres. All on-board avionics, inclusive of the ones mentioned above, plus the mission computer and missile interface unit, have been developed as spinoffs from the BrahMos-1 supersonic multi-role cruise missile’s R & D cycle, which lasted between 1998 and 2005. While the ASQRs and NSQRs for the nuclear-armed Nirbhay were drafted by 2005, hands-on R & D work began in only 2007, with all R & D-related activity due for completion by late 2014.

A spinoff from this programme is the development of a smaller, conventional warhead-armed air-launched subsonic variant of Nirbhay (see illustrations above) with a range of 750km, which will be qualified for launch from combat aircraft like the DARIN 3-standard Jaguar IS as well as Rafale M-MRCA. Presently, there are no plans for developing warship-launched/submarine-launched/surface-launched versions of this missile, which will have an estimated length of 6.2 metres, diameter of 0.6 metres, launch mass of 1,350kg, a 400kg HE blast-fragmentation warhead, cruising altitude of 20 metres over land, cruise speed of 240 metres/second, target aspect angle of +/-180 degrees, and a launch altitude varying between 500 metres and 11,000 metres. The hybrid inertial navigation system will ensure autonomous navigation via at least 15 waypoints, while for terminal guidance, use will be made of a noise-immune guidance system that will employ an X-band monopulse SAR radar similar to the one now being developed for the Prahaar NLOS-BSM. The conventionally-armed ALCM variant of Nirbhay will be procured by both the Indian Air Force and the Indian Navy.

Following the entry into service of the nuclear-armed Nirbhay’s ALCM and SLCM versions, India’s Strategic Forces Command (SFC) will have at its disposal four distinct types of highly survivable nuclear warhead delivery systems that will be optimised for retaliatory nuclear strikes, these being the 4,500km-range SLBM now under development, the 600km-range air-launched supersonic LRCM that is also now under development (for delivering tactical nuclear warheads), plus the Nirbhay’s ALCM and SLCM versions, both of which will be able to deliver boosted-fission nuclear warheads.

For conventional strikes in-depth, precision-strike cruise missiles presently available to India for land-attack comprise the land-launched BrahMos-1’s 290km-range Block-2 and 550km-range Block-3 (for the Indian Army), and 290km-range Novator 3M-14Es that can be launched by both principal surface combatants (the three Project 17 FFGs and three Project 1135.6 Batch -1 FFGs) and by five of the Navy’s nine remaining Type 877EKM SSKs.

Are you sure about its cep? 20m cep is inadequate for a cruise missile, ballistic missiles like islander having better accuracy.
 
Well, Arsanal is correct... for example... India was successful in reaching Mars in its first attempt, whereas everyone else failed. Same way we shouldn't question never failed Babur... :police:

Congratulation DRDO, failures in test will only make it more lethal in action.:toast_sign:

Arsalan, not Arsanal, the Lion, part of the name of the second Seljuk emperor, Alp Arsalan, the Heroic Lion. Don't muck it up; it's always been one of my favourite names, and to find a congenial person with that name was so satisfying. You made me think of sphincters and other necessary but rather avoidable body parts.

And Aghori is NOT my favourite sect either :D

Just kidding (on the second name only).
 
Latest video of nirbhay cruse missile launched today. Here u can see launch sequence, booster phase, separation, wings deployment.. Etc
 
Great news. DRDO should conduct a series of tests and transfer the tech to some private Indian defense firm for it's production by mid-2018
 
650km range, actually reduced range. Is it because of new turbojet engine?

There is going to be a 2nd test which will test other parameters; maybe they'll use the more fuel efficient turbofan then.
 
That looks like the old one
No its new just se the video with dates.. But the photo is only the old one bcoz thats the best pic that we have of nirbhay.. But t he video is 100% authentic
 
What a day!!!

Finally we are making progress in this front. Time about right to integrate these weapons to boomers!!!
