Many thanks. I'm glad you and Nava took notice of the BMD Simulator supplied to the DRDO by TADIRAN SpectraLink in the late 1990s (as its sale was overshadowed by the publicity given to the Green Pine acquisition). <br />Regarding upgrades for the Vijayanta Mk1 MBT, yes the GEC Marconi/Pilkington Optics fire-control system was licence-assembled by BEL AND 400 of these MBTs were also re-engined with MTU diesel-engines. The upgunned T-55s' turret modifications were designed by Poland and subsequently, the SUV-55 fire-control system was imported from Rudi Cajavec of former Yugoslavia. This very same company was also awarded (as you will recall) the contract for upgrading the T-72M's fire-control system (with the SUV-72 and incorporating a Hughes-built gunner's thermal imaging sight) and advance downpayments were made by 1991. But then the civil war broke out and Rudi Cajavec ceased to exist as a corporate entity (I think it is now in Croatia). And of course, the contractual downpayments made by the MoD were never recovered. Since then the T-72Ms and T-72M1s have been subjected to upgrades in two separate tranches, with Tranche 1 (for the T-72 Combat Improved Ajeya) going to Poland and including El-Op's infra-red camera being installed on the gunner's sight. Tranche 2 involved the T-72CIA (the DRDO component) plus the TISAS suite from ELBIT Systems.<br />I'm collating a few more graphics and diagrams on theatre BMD networks and will upload them soon.Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-75596219610489959642009-10-26T12:26:19.414-07:002009-10-26T12:26:19.414-07:00Prasun, I came across some old articles of yours i...Prasun, I came across some old articles of yours in Military Technology on the tank upgrades planned for India.<br /><br />I am led to understand that of the T-72 fleet over 690 now have TISAS sights, upgraded armour etc and other upgrades are planned for the rest.<br /><br />However, what of the T-55 and Vijayantas ?<br /><br />I know the end of their lives is pending but upgrades of some kind were certainly done to the FCS in the Vijayanta (I think a Marconi/BEL FCS was fitted) and to the T-55 (105mm gun, new FCS etc).<br /><br />Can you provide any details on India's tank upgrades that took place in the past or are planned for the future ?<br /><br />For whatever my opinion is worth, your BMD analysis is spot on.

Not 12.

There have been only two Akula-3s built--the Gapard and Nerpa.<br />As the Arihant is only a technology demonstrator, the 85mW nuclear reactor will suffice.

But such interceptions can take place only at the late terminal stage of the inbound ballistic missile's flight and that too at altitudes of less than 40km. Therefore, the Barak-8ER cannot and should not be considered as the magic bullet that guarantees the ultimate solution. And that's precisely the reason why Israel, like India, want to deply BOTH endo-atmospheric and exo-atmospheric hyper-velocity interceptor missiles. There has to be a multi-tier and redundant interception capability in place.<br />The THALES APAR can be used with Aster 15/30 SAMs equipped with active radars for terminal guidance.Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-9471121746975446452009-10-25T10:13:00.200-07:002009-10-25T10:13:00.200-07:00But you just wrote that the Barak 8ER

For the US Navy's Carrier Battle Groups, the answer is a definite yes to deploying sea-based BMD systems like Arrow 2/3 or marinised THAAD. For the Indian Navy such a scenario will not apply as the Indian Navy is not expected to deploy its Carrier Battle Groups in the South China Sea in a faceoff with the PLA Navy. But if Pakistan were to acquire and deploy DF-21C-type missiles, then the Indian Navy will have to revisit the issue of sea-based BMD. At the moment, the Indian Navy is only focused on neutralising the threat posed by land-launched subsonic cruise missiles like the Babur/CJ-10. <br />As to why S-band and X-band APARs on integrated masts are reqd, it is probably best answered by the likes of Lockheed Martin and THALES, both of whom have resolved to developing such integrated masts. Therefore, who am I to throw any more light on this issue?Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-77823366239537462772009-10-25T09:48:37.579-07:002009-10-25T09:48:37.579-07:00To ABHINABA: I refrained from stating anything on ...To ABHINABA: I refrained from stating anything on cryogenic engines simply because there's tonnes of easily accessible literature on this topic and on the application of such propulsion systems, and I don't have anything of a groundbreaking nature to throw more light on this topic.<br />Regarding digitised multi-spectral topographical maps for military applications, both DigitalGlobe and RADARSAT can supply these, and deriving vegetation- or botany-related data from them is a specialised area that is catered to by depts like India's NRSA.

For the Project 15A DDG only the EL/M-2248 MF-STAR S-band APAR will be on board, but the four Project 15B DDGs and seven projected Project 17A FFGs will have integrated masts and it is now up to IAI/ELTA to develop the S-band and X-band APARs for fitment into such a single unitary mast, which could also be retrofitted later on to the three existing Project 15 Delhi-class DDGs. For intercepting inbound supersonic anti-ship cruise missiles, it will not be the Barak-1, but the Barak-8 that will be the principal interceptor.<br /><br />To Anon@9:43PM: When operating from shore-based air bases, a turbofan-powered AEW & CS like the G-550 CAEW & CS has distinct advantages over the E-2D Hawkeye 2000 in terms of both speed (to reach the deployment area) and cruising altitude (to offer enhanced over-the-horizon airspace surveillance/battlespace management capabilities). The choice therefore should be obvious. <br />I'm not aware of any plan of the Indian Navy to have conventional flat-top aircraft carriers (as only these can have any kind of catapult-based aircraft launch system).Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-66444917498839488792009-10-25T09:23:44.664-07:002009-10-25T09:23:44.664-07:00To hacker: The LRTRs to be deployed in operational...To hacker: The LRTRs to be deployed in operational configuration will be upgraded and enhanced to something resembling the Raytheon GBR which is presently used for the THAAD. Presently, the PAD uses the LRTR whereas the AAD uses the Master-A, but the main challenge now is to use a single tracking-cum-engagement radar for the combined PAD/AAD BMD system. The Barak-8ER LR-SAM will be able to intercept targets to a projected altitude of 37km. While the Barak-8 will be able to intercept supersonic cruise missiles like the BrahMos, the Barak-8ER will be able to intercept anti-ship ballistic missiles using depressed trajectories, such as that of the DF-21C and Shourya (yes, the Shourya too can be used as an ASBM).<br /><br />To Anon@7:05PM: What you're suggesting (deploying armed loitering UCAVs in a pre-emptive first strike against Chinese nuclear ballistic missiles) does not apply to India as the latter has a no first-strike and a retaliatory second strike policy. For BMD, the US definitely (and to a lesser extent Europe) is willing to rope in India along with Australia, Japan, Taiwan and South Korea to co-develop and deploy a regional BMD network.Prasun K Senguptahttps://www.blogger.com/profile/00369323150694008798noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-3397289647138085622009-10-25T00:22:30.142-07:002009-10-25T00:22:30.142-07:00This comment has been removed by the author.ABHINABAhttps://www.blogger.com/profile/07443826784908284383noreply@blogger.comtag:blogger.com,1999:blog-5154280302945875495.post-63499232195003916662009-10-24T23:56:44.962-07:002009-10-24T23:56:44.962-07:00Well, you ignore my query about cryogenic engine. ...Well, you ignore my query about cryogenic engine.
