Re: CLGM Tests Successful

DRDO's CLGM Development Programme Appears To Be Progressing Well - AA Me, IN

he Pune-based DRDO lab, Armament Research & Development Establishment [ARDE] has initiated a tendering process to award a contract for supplying the Guidance system used in its Cannon-launched Laser Guided Missile [CLGM], presently under Cannon-Launched-Guided-Missile-CLGM-Indiadevelopment. The Indian company eventually chosen would have to provide 30 units of the system, that it would need to build in conformance with the design drawings, manufacturing process & quality standards provided to it by the concerned DRDO lab.

The tender for limited-scale manufacturing of this critical sub-system suggests that its developers have acquired a fair level of confidence with their design, not foreseeing the need for substantial re-design in the future, & are ready to take things forward. Once the final design is locked, large-scale production would be taken up by one of the designated DPSUs. Additionally, news of the postponement of an impending test wasn't followed up with the news of any test having take place subsequently. Could suggest faults were detected pre-flight, they went back to the drawing boards, & are now ready with corrected designs. The CLGM had tested success earlier in the year.

This assessment, if true either way, bodes well for the country's missile inventory. The 5 km range CLGM can target armoured vehicles, including Tanks, as well as low-flying aircrafts. It can be fired, both, from the barrel of the indigenous Arjun MBT, thus enhancing that platform's versatility, as well as a standalone system, that can be lugged around by soldiers. India's other indigenous Anti-Tank Guided Missile [ATGM], the Nag, on the other hand, is incompatible with the Arjun Tank, & is much too heavy to function as a man portable anti-tank system. News reports indicate intention to develop a lighter version of the Nag, although no trial launches have taken place, so far. Therefore, to plug in this gap in the arsenal, India intends to import the Israeli LAHAT missiles to kit its presently missile-nude Arjun. In addition, it is also contemplating whether to go for the American Javelin or the Israeli Spike missiles to replace its inventory of older man portable ATGMs. A smooth, preferably accelerated, development of the CLGM could lessen the number of the above mentioned missiles that are to be imported. The CLGM would also enjoy an advantage over the LAHAT in terms of its Guidance System used. While the latter employs a solely laser designated targeting system, the Indian solution is to have both direct/indirect laser designation, as well as heat seeking terminal guidance capability.

Re: CLGM Tests Sucessful

Warhead is heavy as per our requirement, plus it can be launched from cannon.
LAHAT too can be fired from a cannon, isn't it? Recently when some problems with smoke inside the cabin was reported during Arjun Mk II firing trials, wasn't the LAHAT one among the cannon-fired projectiles?

Indigenous Seeker Technology

Let's discuss Indigenous seeker technology which has been developed by PSUs.

So far as we know, PSUs have already developed the following technologies:
  • Retransmission Seeker (Akash Mk1)
  • IIR (NAG)
  • X Band SAR Radar Seeker (Astra/AAD/PAD)
  • Laser seeker (PGMs/CLGM/SAMHO)
  • MMW Active Radar Seeker Seeker (HELINA)
  • SatNav (G3OP)
  • Laser Gyro INS

In the process of development:
  • Electro-Optical Seeker (QRSAM)
  • Anti-Radiation seeker (ARM)
  • Ku-Band Seeker (Astra Mk2)

Technologies which are imported/developed under JV:
  • Multi-spectral active radar seeker (Barak 8)
  • X Band Imaging & Monopulse Seeker (BrahMos)

Re: Indigenous Seeker Technology

For a layman, please educate me on what is a seeker, what does it do, where is it fitted in the missile and what different kind seekers are there. My knowledge is limited to knowing that it works in the terminal phase and leads missile to its target.

At the same time please evaluate Indian seekers now with DRDO and how reliable these are.

Re: Indigenous Seeker Technology

Is it G3OP or G3OM? G3OM - is not a seeker but a parallel system to Seeker technology. G3OM augments the signals from GPS, GLONASS, GAGAN on a Module and guides the missile towards the target.

Advantage of G3OM

- Indigneious, a first of its kind in world developed by RCI hyderabad and produced by Accord software company in Bangalore,tested for first time in world on brahmos.
- Helps in Miniaturizing missiles as seekers consume lot of space whereas G3OM weighs just 17 gms and require few cm of the space
- Cost of missile gets reduced, seeker is a high tech device which cost nearly 40% of the missile cost
- As the weight of missile reduced,range and speed automatically increases thereby increasing effeciency
- Accuracy if below 5 ms.

Disadvantages

- GPS signals tend to be weak and can be easily jammed although there are steps to avoid. if Signals are jammed,the missiles will be completly rendered useless.
- we do not have access to military grade signals of GPS and GLONASS. Chinese by having ASAT capability can easily target GAGAN satellites.Although it will be impossible for us to get military grade signals from GPS,talks are going on to get military grade signals from glonass which are difficult to jam than normal signals.
- Currently its not tested completly and still in its Nascent Stage

PMO nod for 6k crore Seeker manufacturing plant

DRDO to manufacture indigenous air missile defence systems

In keeping with its policy of prioritising indigenisation of Defence production, the PMO has given an "in-principle" approval for setting up of an Rs 6,000-crore facility by the Defence Research and Development Organisation (DRDO) for manufacture of Seeker, a key technology for air missile defence systems.

Prime Minister Narendra Modi gave the go ahead on July 1 for the setting up of a fabrication facility for production of the Seeker.
The DRDO has been asked to move a Cabinet note for approval by the Cabinet Committee on Security (CCS). Following clearance from the CCS, the setting up of the proposed facility will be taken up by the lead research agency, an official said.

Only Seeker-based state-of-the-art missile systems can counter challenges from simultaneous multiple target air threat from any direction and at present the DRDO imports Seekers for its missile systems like Astra, long-range surface-to-air missile (LRSAM) and Brahmos.

Absence of Seeker technology has limited the capabilities of indigenous missile systems like Akash surface-to-air missiles and anti-tank Nag missile. While Akash and Nag are designed to follow one target, the Seekers can enable a missile system to keep an eye on multiple incoming missiles. Seekers can help a missile follow as many as 32 targets.

Officials said mass production of indigenous Seekers will help reduce the cost of the missiles in the long run.

Seeker technology is available with a few countries like the USA, Russia, France and Israel and the DRDO's efforts to develop the technology have not borne fruit for the last two decades.

While France offered Seekers as part of the offer for acquisition of short-range surface-to-air missile defence system (SRSAM) in 2006, the US recently offered its Javelin missile system. The US gave the offer during the recent official visit of its Defence Secretary Chuck Hagel here.

Both the countries have offered transfer of technology, co-development and co-production with an Indian PSU and proposals are under consideration by the Centre.

A government-to-government agreement was signed between India and France for cooperation in missile development way back in 2006. While India nominated DRDO as the design authority with the task of developing the ground elements like radars and launchers, France authorized MBDA for facilitating transfer of technology (ToT) for SRSAM including Seekers.

Under the agreement, only the missiles were to be jointly developed by DRDO and MBDA and all other sub-systems were supposed to be produced by Indian industries.

The offer also included setting up of automated assembly lines for missile production to meet the delivery schedules. The Defence PSU Bharat Dynamics Ltd. does not have automated assembly lines and relies on manual methods.

However, the agreement moved at snail's pace during the two UPA regimes and the CCS approved price negotiation (PNC) with MBDA in 2010. The PNC was completed in 2012 and was approved by the Defence Acquisition Council in early 2013. Draft CCS note for final approval of the project was forwarded in 2013 by the Defence Ministry to the Finance Ministry and a final nod is awaited from the latter.

Intelligence sources tracking Defence preparedness said production of Seekers by DRDO through ToT will result in development of indigenous industry and limit any dependence on foreign countries.
