The Agni-5 will not form the basis for the SLBM. The SLBM will be required for obvious reasons tobe more compact without any limitations on the operationally mandated range envelope. Consequently, the SLBM will be a brand-new design.<br />Regarding Project 75A, the only viable contenders include the joint Fincantieri/Rosoboronexport offer of the S-800A, and DCNI's SMX-22. The S-1000 from Fincantieri is NOT on offer as it is derived from the much smaller Amur 650. But people make mistakes since the design of the S-800A has not yet been publicly released, but it does exist and the Indian Navy was briefed about it TWO YEARS AGO.Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-32761264831328033542009-08-01T03:35:52.784-07:002009-08-01T03:35:52.784-07:00http://www.hinduonnet.com/2005/03/23/stories/20050...http://www.hinduonnet.com/2005/03/23/stories/2005032303021300.htm<br /><br />Does this arrangement extend to Arihant class submarines too?

I say this because producing a smaller-more compact missile(abt13-14m in length) with 8500km range for land based leg would also give better mobility to land based assets which currently use A2 which i think is some 16-17 mtres long.Thus the Agni-5 tests would be crucial as it would be validating the basic technologies reqd for developing ICBM(techs like advance composits for structural use,better more accurate rlgs,communication modules,launch modules DefMin indicated it could be canisterised)).ur thoughts?sachin_sathehttps://www.blogger.com/profile/02104023701292128933noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-73088865904375161252009-07-31T17:14:48.851-07:002009-07-31T17:14:48.851-07:00there are two separate things

The Russia-designed SGPFS 8-cell VLS for the Club-N/S and BrahMos comes from a different entity, i.e. Concern Morinformsystem-AGAT JSC and they have no involvement with the ATV. Even the 8-cell and 16-cell VLS cells for the BrahMos (on the Project 1135.6 FFGs Batch 2 and 3 and on the Project 15A/15B DDGs) are fabricated by L & T, and not the Russian company. And do kieep the propellers on the ATV design exposed for now, there's no propulsor (which of course will not be evident to the BR wannabes who in their all-knowing wisdom cannot even distinguish between a 'paraiah' and a 'pariah', and are too bankrupt to visit the defence/aerospsace expos worldwide to get first-hand data on military-industrial developments!

It was only AFTER the conclusion of the exercises, when the carrier battle group was vound back to its homeport that the SSN reappeared and surfaced, God knows why! Now what happened after that is a very interesting story. The US Navy launched a crash programme in great secrecy to deploy an ultra-low frequency dunking sonar in an innovative manner to ensure speedy deployment. Accordingly, a RHIB was hastily modified as an unmanned surface vessel and was equipped with a hydraulic winch connected to a HELRAS untra-low frequency dunking sonar developed by L-3 Ocean Systems Division. Up until then the HELRAS, although developed in the US, had been ordered only by Egypt and Italy (Singapore followed later). For the past two years now, such RHIBs equipped with the HELRAS are mandatorily deployed by all US Navy carrier battle groups in the Western Pacific. The Indian Navy too has openly declared its interest in acquiring this dunking sonar, instead of the low-frequency and inferior Mihir system. Just to give you an idea, while the Mihir can 'theoretically' detect submerged targets in shallow waters out to a mere 7nm, the HELRAS has a detection range exceeding 20nm!Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-88194147088483241662009-07-31T14:49:40.404-07:002009-07-31T14:49:40.404-07:00To Sachin Sathe: As I mentioned earlier, the plann...To Sachin Sathe: As I mentioned earlier, the planned HATs and SATs of the ATV will be hampered more by the current lack of shore-based infrastructure (the majority of which will have to be allocated for the Akula-3) and seaborne hardware like the DSRV. On top of that, the DRDO has yet to begin work on designing the 8,500km-range SLBM. Therefore, the ATV will in all likelihood remain a technology demonstrator platform until the SLBM is ready for service induction, probably after 7 to 10 years. In the meantime, the submerged test-firings from the VLS of the BrahMos will be carried out, purely for design launch validation purposes, as BrahMos Aerospace desperately requires such work to be undertaken if it is to offer the BrahMos for the planned six Project 75A SSKs. Other systems to be tested out on board the ATV will be the flank-array sonar and the spherical bow-mounted sonar (they were not available from either Russia or France when the ATV's design was frozen and therefore on the ATV now the flank-array sonar is missing, while the existing Ushus cylindircal sonar transducer is still a low-frequency system (like the Humsa-NG, and both of these are a generation away from the ultra-low frequency spherical sonars already operational with the US Navy and now entering service with the French Navy). The spherical sonar on the Russian Yasen SSGN too is of the low-frequency-type, i.e. a generation behind contemporary systems. I will soon be uploading the Yasen's cylindrical bow-mounted sonar transducer, and also the inner pressure hull sections of the ATV while they were being welded together at the SBC.Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-25327756804675606052009-07-31T11:08:39.925-07:002009-07-31T11:08:39.925-07:00To Harpreet: Many thanks.

After I do that, kindly pay close attention to the Akula-3's more aft-mounted compact gondola mounted on the aft vertical fin, which houses a low-frequency thin-line towed-array sonar suite.
