Jaitley hands over long-range surface-to-air missile to Navy

The LRSAM was jointly developed by India and Israel

Hyderabad, August 27:
Defence Minister Arun Jaitley on Sunday handed over the Long-Range Surface-to-Air Missile (LRSAM) jointly developed by India and Israel, to the Indian Navy, at Bharat Dynamics Ltd (BDL) here.

LRSAM is an advanced combat suit for missile defence against air targets and missiles, and has full capabilities of air and surface surveillance, threat alert and fire control.

Public sector BDL is the missile production agency for the three armed forces.

On a day of hectic activity, the minister also dedicated a first-of-i-s kind 50-tonne Rocket Motor Static Test Facility. The ₹48-crore facility for SAM (surface-to-air missile) will support the design and vendor development activities needed for production of missiles.

These efforts were hitherto shouldered by the Defence Research and Development Organisation DRDO as the development agency.

BDL is now equipped to take the responsibility on its own, which has been actively guided for realisation and establishment by DRDO.

Later, Jaitley inaugurated the ASTRA Manufacturing Unit at the BDL’s Bhanur unit. The ASTRA weapon system is an indigenously developed air-to-air Beyond Visual Range (BVR) missile developed by the DRDO.

Comprising a launcher and a missile, it is designed as a BVR missile with a range of 110 km in head-on mode and 20 km in tail-chase mode.

BVR missiles are the latest in air-to-air combat. BDL has been designated as the Lead Integrator by the DRDO.

Manufacturing centre

The minister also performed the ground breaking of the phase II of the manufacturing facilities of BDL at Ibrahimpatnam. BDL had acquired 632 acres of land from the State government to establish manufacturing, testing and storage facilities for advanced weapon systems of MRSAM (Medium Range Surface-to-Air Missiles) and QRSAM (Quick-Reaction Surface-to-Air Missile).

The ₹522-crore facility will be the PSU’s future weapon realisation and delivery centre.

The facilities will meet the future needs of missile testing, and is in line with DRDO labs.

Nice move towards indigenisation in defense

Hope this time the deal goes through under the SPP make in india model and i am sure if Sikorsky bags the deal it will be Tata which will be manufacturing them ..They are already making the cabins for the S-92 in their Hyderabad facility ...We badly need these helos most of our new ships getting commissioned are without a Helo which is a main protection from submarines...

They are gonna tweak their "requirements" to make sure Dhruv does not fit in. Or how will they get their kickbacks?

I would have loved to see Dhruv as LUH and HAL IMRH as the NMRH.

But we are out of time as far as NMRH is concerned. We needed these yesterday and IMRH is still on the drawing board. Who knows when it will come out. However I hope this tender does not get delayed and that the winner starts churning out those choppers for IN as soon as he is declared winner. If deliveries do not begin by 2020, the tender will be better of being canceled. By then, IMRH would be up and flying. It would make more sense to wait for IMRH induction in the next couple years.

Was Dhruv considered as Naval LUH role or does is not meet the specs? BTW what are the specs?

Being eternally prepared in an extraordinary manner is not correct. It is like a student who studied entire night and fell asleep during exam. We have limited ability and resources. Nothing is infinite. So, we must not show undue haste. Let IMRH and HTSE be produced first. It will take till 2021 considering Indian experience in LUH, Rudra and LCH production. If congress was there then no matter what, nothing would happen. But without congress, lot of progress will take place. Unduly hurrying to import and then being eternally dependent for another 10 years for spare parts is foolish.

LUH or Rudra is unfit to be ASW aircraft as payload capacity of 4-5 ton is needed to carry complex equipment to detect submarine, Torpedoes, people and weapons for aerial defence. Rudra is also too small to have enough space to fit in many equipment for multirole missions.

@DRDO_India's SSPL lab has managed to develop a blue laser based submarine communication system.

@DRDO_India's SSPL lab has managed to develop a blue laser based submarine communication system.

What is the range of such a blue laser

 

[Vinod DX9]

Under water communication system,this is indeed a great achievement

I am not sure,but may be GaN sources have been used. Many were trying to establush a new gen communication system with GaN, may be our one too followed this

Is this the one where the Submarine need not come on the surface to communicate with the land based command and control ? It was reported few years that that we have developed a system to communicate with Submarines that does not need to come out of the water... specially for nuclear Subs...

 

[Cutting Edge 2]

What is the range of such a blue laser

Exact details are not known but roughly underwater laser communication systems have range of a few kilometres, Somewhere in the ballpark of 10km. Range also depends on many variables.

Underwater laser communication system is mainly used to transmit secure data (in kilobytes) between sub to nearby surface vassals. e.g. CVBG

 

[Vinod DX9]

Yes Bose and Cuttng Edge 2
Radio frequency (RF) channels and satellite links on ships are often limited to data rates of some hundreds of kilobits per second to some megabits per second. To communicate Submarines often have to surface. Laser links offer the opportunity to overcome these restrictions for optical line-of-sight communications due to the very high frequencies used and, when compared to conventional RF links, the angle of the transmitting laser beam is small. This is done by using a laser pulse tuned to ionize water, and generate an acoustic pulse. Thus surface ships or aircraft could communicate with suitably equipped subs. There is an optical window in the blue-green part of the spectrum which enables laser transmissions to penetrate the ocean a substantial distance. The laser based system enables a submerged submarine to communicate near by anti submarine warfare role ships or aircrafts easily.

No big ships being inducted into IN this year is it?

The two P-28's are supposed to be commissioned this year.

Rumours: US-2 back in MoD's radar.

Is that independence class littoral combat vessel? What is so great about that which Indian navy can't build for itself? Why need US technology for it?

I would have used a bunch of submarines or submarine-drones to triangulate things on the ocean surface with this tech. Subs can get very close to armadas already.

With something like this a highly accurate very stable and very fast fix for an off board targeting of would be a piece of cake.

Is China ahead of us or behind us in this technology?

Hai Ram.

Well, INS Aridhaman and 3rd Scorpene submarine will be launched in this year. INS Kaveri will be inducted.

Thanks bro. But most of my posts are baits. Pls don't take the bait if you don't intend to mess with me. It was not meant for you.

I had laid the bait for people who think DF-21D and DF-26 is useless. If it was useless then they would not have advertised it so much. But if it was useful then there must be some basis to the confidence. Nahi kya?

China’s latest missile test shows country can respond to aircraft carriers, THAAD
By Deng Xiaoci Source:Global Times Published: 2017/5/10 15:28:39
"To judge from the missile remains disclosed by media, it was a DF-26 that was tested recently, also known as the 'aircraft carrier killer' missile," Song Zhongping, a military expert who used to serve in the PLA Rocket Force, told the Global Times

"Considering the type of missile and the test location it is evident that we conducted a firing experiment targeting aircraft carriers, and the warhead possibly featured an electromagnetic pulse that could destroy a carrier's command system, as well as the THAAD system," Song noted.

Question arises, ab India kya karega? Import?

What kind of radars or ships and submarines are islamic countries able to make?
