There is no question about it. These things are not a matter of opinion. I have had the photo checked out and compared, and being someone who knows, i dare say, a little about submarines, this is without doubt the Akula-II. Secondly, India's first nuclear sub platform (i understand it is being named INS Arihant) will not have a rear dorsal towed array sonar pod. the pod will only be part of the second and third boats. therefore, that rules out the accuracy of the model you have posted. it's ok to get it wrong sometimes, prasun. it takes a little credibility to admit your mistakes and move on. you have a great blog. just don't push something you "think" is correct, when others tell you otherwise.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-14985844659493322192009-07-17T23:57:12.928-07:002009-07-17T23:57:12.928-07:00Does everyone think India will actually announce t...Does everyone think India will actually announce the commissioning on July 26th.

But the co-development project was inked in late 2003 and it is meant for the ATV technology demonstrator. Unlike the DIEHL-built IDAS, It won't be guided by fibre-optic cables. <br /><br />To Subroto: GAGAN is not the same of India's proposed regional constellation of GPS navigation satellites. The ‘Beidou’ regional GPS-based satellite navigation system's satellites are built to rubidium atomic frequency standard. With a space segment of five satellites in geostationary orbit and 30 non-geostationary orbit satellites, the ‘Beidou’ constellation will provide continuous real-time passive three-dimensional positioning and speed measurement, precise timing and user-position reporting. The satellites will be based on the proven DFH-3 bus that are already operational on board China’s existing telecommunications satellites, and will have a lifespan of eight years. The first five satellites were parked at their geostationary orbits by 2008. Navigation services open to commercial customers will provide users with positioning accuracy ro within 10 metres (33 feet), velocity accuracy within 0.2 metres per second and timing accuracy within 50 nanoseconds.<br />I'll upload the Beidou's information board posters tonight (they're from the 2008 Airshow China expo in Zhuhai).<br /> <br />To Anon@3:06AM: The Barak-8 MR-SAM has active radar for terminal homing, but the Barak-8ER LR-SAM has dual-mode guidance.

Metal bladders installed in the shroud will be inflated to eject the protective shroud before the combined seekers initiate target acquisition.[This is the mechanism of Rafael's Iron Dome inteseptor called Tamir]"<br /><br />Barak 8 according to IAI website only uses an ARH seeker.<br />Bracket comments are inserted by me.<br /><br /><br />Dear PKS, can u please clarify this?

China plans to send 10 navigation satellites into the space in 2009 and 2010 and total 30 satellites into the space by 2015.<br /><br />You have mentioned that India under GAGAN project will launch a regional constellation of at least seven GPS satellites for both civil and military applications:<br />1. How do you compare Indian "GAGAN" with the Chinese "Beidou" Navigation system?<br /><br />2. ISRO plan GAGAN-SBAS project with the partnership of US Raytheon Company, will there be any condition clause attach with it as India's access to Russian “GLONASS' Py-codes is conditional.<br /><br />3.

By designing non-nuclear modular and carrying out quietning process it(Malachite) stoned 3 birds it got royalties for such sale,developed newer quietening and noise suppression(non-nuclear) systems for next-gen russian ssn/ssgn and stayed legal at the same time a win-win situation for bot India and Ru. <br /><br />As far as the reverse engineering reactor goes i guess it is the right path as it allow the DAE & BARC to give proper time and knowledge to develope an indian reactor(probably based on CHTR project)<br /><br />Regarding the M2k upgrade i think they r going to extensively upgrade the aircraft with TOT(which may become an advantage for Rafale(regarding(weapon systems)) also the deal includes MICA missiles which i heard are quite expensive.So it really depends upon the upgrade list as far as cost is concerned.If a missile like MICA is being imported in large nos along with a new anti-radiation missile and ability to integrate Iseraeli weapons then it would be as expensive as it is predicted. Also with coming induction of MMRCA and LCA the load of pricision and surgical strikes tht was on M@K will also reduce(the newer Jag upgrade reduces it even further.)<br />Also the french weapons have always been expensive but they have always given splendid performance when required.<br /><br />The MDL is a logical choice as it will have garnered some precious experience and the Know-how along with Hardware in the scorpene project for Non-nuclear modular production.With the announcement large scale disinvestment in PSU's we can expect the political hassels and MOD's non-performance in paper-pushing to be reduced greatly .sachin_sathehttps://www.blogger.com/profile/02104023701292128933noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-71202235652529696112009-07-14T21:05:45.748-07:002009-07-14T21:05:45.748-07:00This comment has been removed by the author.sachin_sathehttps://www.blogger.com/profile/02104023701292128933noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-92128370691838306812009-07-14T18:38:31.021-07:002009-07-14T18:38:31.021-07:00Prasun Da,

An IDAS-like system is being jointly developed by the DRDO and RAFAEL. It will be derived from the Python-5. Regarding the SSGN design from Malachite, only the non-nuclear modules have been supplied by Malachite. As far as the nuclear reactor goes, it is a derivative of a civilian reactor originally designed for civilian ice-breakers. This same reactor design was 'reverse-engineered' by the DAE and is also on board the ATV technology demonstrator. As for the air-launched ADM it will definitely be more capable than the BrahMos as the 290km-range limitation will not apply. The terminal flight phase of the ADM will definitely be supersonic.<br /><br />To ABHINABA: There's no way anyone will a permanent sale of any SSGN or SSBN as it violates the NPT. <br /><br />To Anon@5:58AM: The ATV is a technology demonstrator and will never be inducted into operational service. The Akula-3 on the other hand is an operational SSGN.<br /><br />To Anon@7:20AM: Even without the ADM the S-300/S-400 can be defeated and overcome. How? Through an air campaign's 'operational art'. The ADM and sub-launched cruise missile will use its turbofan only in the cruise phase while in the terminal phase the solid rocket motor will kick in. <br /><br />To Anon@5:55AM: Why should a sub-launched Popeye go on board a Kilo-class SSK when the 3M14E Club-S is available?<br /><br />To Anon@7:39AM: I'm not aware of the BrahMos 2 emerging with scramjets. All that BrahMos Aerospace has publicly stated thus far is that BrahMos 2's cruise speed will exceed Mach 5. <br /><br />To Anon@7:57AM: It will be the RDY-2, so that the upgrade costs can be keep affordable. It still is a sheer waste of money. Far better to spend the money on acquiring additional Su-30MKIs rather than waste it on upgrading the MiG-29s and Mirage 2000s. This continues to be my personal stand. <br /><br />To Raghav: Russia did not supply any made-to-order hardware for the ATV. That's what I meant. Only after the ATV validates several key design/performance attributes <br />will the MoD decide which shipyard will manufacture the SSGNs and SSBN. All indications are that it will be MDL in Mumbai, with companies like L & T, Jindal Steel and TATA Electric (and their foreign industrial ToT partners) emerging as the major sub-contractors. MDL has already begun the process of acquiring additional real estate for constructing a dedicated final assembly line for the SSGNs/SSBN. <br />Regarding the Shourya, even if its range can be increased to 1,200km I don't think it will be ideal for the SSBN.

Also such arrange means tht it can be used in bunker buster mode.<br /><br />Also with the the ADM can also be developed as surface launched varient replacing BrahMos.Reducing the cost even lower.If the third stage cylinder is kept common with motor and seeker(warhead will be larger for cruise missile) then it would meen confirmed production of nearly 5000+ missiles(including surface to air versions as MRSAM). Meaning big time cost savings and thus making it more feasible than BrahMos whose range is not only capped at 300kms but also cost enormously.<br /><br />wht do u think?sachin_sathehttps://www.blogger.com/profile/02104023701292128933noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-55488406302613452382009-07-14T07:34:18.898-07:002009-07-14T07:34:18.898-07:00This comment has been removed by the author.sachin_sathehttps://www.blogger.com/profile/02104023701292128933noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-43727424818250389722009-07-14T07:20:27.928-07:002009-07-14T07:20:27.928-07:00Prasun da,
