First technology cannot be purchased and used just like that. This is common misconception which is read only in newsmagazines and defence magazines
It has to be developed with involvement and with user acceptance. Otherwise, you get only LRU which is of limited use and is not of good value for long term project
In DRDO, the plan is to only go for those item which is either too long to develop in India, or too expensive to develop from basic, or which can be leveraged into more development items.
What this means is that extensive involvement is done. You cannot just buy technology and use it because you dont understand it.
So the option is to codevelop and use joint research on some specific item and make rest in India, and then develop the rest more and replace with indian IP as requirements need the same.
User also has say at every level if it is user specific project and not a technology development project.
So this is why "Buy and Use" approach doesnt work. DRDO cannot just buy out technology and call its own. It is useless. You cannot even integrate such technology with own equipment because your own equipment will not at all work with bought out technology designed for other system
this is also why HAL MMR had problems. By time, airborne tests showed ground mapping mode was full of bugs it was not useful to even purchase OTS module for mapping from OEMs since OEM module will not work for MMR
earlier SAAB ERICCSON had offered help which was also refused for same reason because MMR work required too much time to use SAAB Software
So you see you cannot just buy and use unlike what some believe
I hope this answers your question.
Presently LRDE is also working on many new Radar for user which will make suitable impact when released. I hope you, my friends will be suitably happy with developments. Once this is done within coming 2 years, India will be 80 percent self reliant in radars. These are new generation, frequency agile, 3D Radars with electronic scanning. WLR has also gone through trials successfully and user is very satisfied with the same and will be standard radar in the role for the user.
Ravi, since you seem like an inside guy, can you throw some light on how much of LRTR is indegenous? how much individual components do we source from Israel or US?
Dear freind, its best we do not talk of LRTR and ABM in public space because it is strategic program. But do not worry, LRTR is for local manufacture. India do not source radar systems for local program from US, there is reality that ITAR issue is still a problem.
There is this doubt that it is GreenPine re-branded. Also the range of this radar mentioned on public domain is very confusing.
It is not GreenPine
DRDO worked with Israel to make own radar specific for ABM program.
The range is sufficient for long range gating and acquisition, and yes range specifics is not mentioned publically for LRTR or tom-tomed because it will give a clear idea of system growth capability
Also this radar is considered AESA, while we seem to be struggling with that technology. If I am not wrong, many international firms extending invites for participation on AESA joint ventures means, India is lacking somewhere.
friend, we are not struggling with AESA. Thanks to rajendra program and project AKASH we are now sufficiently aware of and capable with electronic scanning radars.
What we are to sufficiently grow in is airborne radar for fast moving platform like fighter jets. This is entirely qualitatively different field than system for long range surveillance based on stationary platform (AKASH, Program AD) and even air based surveillance system which are not on fast moving jets of speed like fighter aircraft
fighter jet radar are having stabilisation plus long range multi surveillance modes in compact package with anti clutter measures
This is area where some 8 OEMs are having experience in worldwide
This is where foreign OEM are offering cooperation and not just in AESA systems where we have indeed got sufficient growth capability and experience
Actually how good is this radar? how many would we need for a BMD?
LRTR is worldclass system, and one is required for every deployment which can have different battery attached depending on threat
