Countries like Turkey have indigenous companies that can design and build APCs. The winning selection for a Taiwanese APC was from Ireland. I hope that with the JVs with America it could take up the techniques for manufacturing and QA/QC that you mentioned.

This same twin-pack will go on the LCH as well. In other words, mo quad-pack like the ones on the Apache or Tigre. If the IA & IAF want, they can easily remove the Mistral-ATAMs & take in two extra twin-packs so that both helicopters will carry 8 x PARS-3LR. For the HELINA, nothing's decided so far, since the HELINA as it is now configured is bigger & heavier than the PARS-3LR or even the Spike-LR. Prasun K.

Its just a matter of having an ejector rack that carries 4 ATGMs (stacked in rows of 2, one above and one below). So why can't that be done with the HELINA and LCH?Bhaswarhttps://www.blogger.com/profile/13654231099908820832noreply@blogger.comtag:blogger.com,1999:blog-3545138702780178046.post-70019627470329742862013-09-25T02:38:12.039+05:302013-09-25T02:38:12.039+05:30To K SHEKAR: I tend to go by what the OEM or DRDO ...To K SHEKAR: I tend to go by what the OEM or DRDO states, instead of relying on third-party reports by private consultants. Consequently, the two reports cited by you are contradictory, since one claims that a 100W S-band T/R module was fabricated by ASTRA but the other says that the DRDO has developed a 200W S-band T/R module. If one were to believe what the DRDO has stated, then it means that the 200W T/R module has been selected (instead of the 100W module) for both the L-STAR & its shorter version that is now on the EMB-145I. As I had explained in my DEFEXPO 2012 show report in April 2012, the production version of the S-band radar’s antenna will be shorter than the L-STAR. Therefore, the no of on-board S-band T/R modules cannot be the same for both antennae. Lastly, during both DEFEXPO 2012 & Aero India 2013, ASTRA’s booth never displayed any S-band T/R module, only S-band dual receive module & S-band dual transmit module, & not any combined T/R module. BEL on the other hand showcased its L-band T/R module & C-band quad T/R module. It’s all very clearly shown in my Aero India 2013 show report threads.Prasun K.

Firstly, it was the 8km-range HELINA equipped with MMW seeker that was test-fired on September 22, 2013 & NOT 4km-range cooled LWIR-sensor equipped NAG & NOT FROM NAMICA. The missile was test-fired from a customised & raised pedestal out to a range of 7km because the two IA-owned Dhruv WSI prototypes are presently unavailable from HAL to the DRDO for conducting the test-firings. Secondly, a 10km-range version of HELINA is now under development for being launched from fixed-wing MRCAs like Tejas Mk1. Thirdly, there will be no ground-launched version of HELINA. Fourthly, the ONLY DRDO-developed manportable ATGM now being readied for firing trials is the laser-guided 5km-range SAMHO, & not the NAG. Fifth, both the Rudra & LCH will each carry only 4 HELINAs in twin-packs (similar to what has been developed by MBDA for PARS-3LR ATGM) & four Mistral-ATAM air-to-air missiles. This is obvious when once visually examines the stub-wings on both both these helicopters. Sixth, the two-way RF command-video data-link developed by DRDO is for the NAMICA (which now has an ELBIT Systems-developed & BEL-assembled COMPASS optronic turret for target detection/acquisition) & not for HELINA since the HELINA will have MMW seeker (incapable of generating any video imagery of its target) from the very outset & not a cooled LWIR sensor. Thus, as you can see, the ‘desi’ news-reporter was evidently unable to make any sense out of the technical/performance parameters of either the HELINA or NAG or NAMICA & consequently, what has emerged is nonsensical gobbledygook. <br /><br />To BUDDHA: Not at the moment. And for launching VLAPs like the ERGM one would require 127mm or better still, 155mm naval guns, both of which the IN does not possess.<br /><br />To JOYDEEP GHOSH: 1) I never said India was looking for multi-calibre gun, but it is both the IA & DRDO that have officially stated that the IA requires multi-calibre assault rifles & it is the DRDO that has admitted that it is developed one such rifle. 2) Whosoever made such observations against attack helicopters is obviously neither literate nor educated. Why? Simply because heavy armoured formations never manoeuvre along mountains, they do so only in the plains as was the case in 1965 & 1971. In addition, attack helicopters are also used for various other roles, like attacking hostile air-defence radars, as was the case in January 1991 when the Apaches were the first to go inside southwestern Iraq to destroy a long-range airspace surveillance radar. 3) You did not mention the years, but mentioned the events which took place in those years. Doesn’t mean there’s any merit in those cases. 4) Such ‘assault-breaker’ dispensers were developed by both Germany & South Africa in the 1980s itself for the Tornado IDS & Mirage F-1s.Prasun K.

HAL only states that the LCH’s maximum all-up weight will be 5.7 tonnes. MMW radar can easily be mounted atop any of the two the stub-wings of the LCH. To try to mount it on the rotor-head will require extensive re-designing & be time-consuming. Most of the avionics/instrumentation & navigation system is imported as well. The LCH was designed by TATA Alexys. <br /><br />To VIKRAM GUHA: 1) The truck-mounted Ashwin active phased-array radar being developed by vData Patterns Pvt Ltd for the DRDO/MBDA SR-SAM can easily be used as an LPI-GFCR. 2) Of course. <br /><br />To MUTTU: Most unlikely. <br /><br />To K SHEKAR: ASTRA Microwave has assembled only L-band & Ku-band T/R modules (whose photos I had uploaded just after Aero India 2013), whereas the EMB-145I AEW & CS uses an S-band active phased-array antenna. Therefore, anyone claiming that ASTRA makes S-band T/R modules is totally unaware of elementary facts. No one has to date released any data on the number of T/R modules present on the S-band antenna or their peak transmitting power output. And no one ever will, at least for public consumption, be it ASTRA or THALES or RAYTHEON or IAI/ELTA or EADS/Casssidian or SELEX/Galileo or Northrop Grumman or Phazotron or NIIP Tikhomirov. Therefore, anyone blurting out numbers is only speculating.Prasun K.

Facts sp...To BHASWAR KUMAR: What about them indeed! Facts speak for themselves. For instance, if the DRDO-developed ring laser gyro-based inertial navigation system (RLG-INS) coupled to GPS receiver is that good, then how come this system is not on board any of the Tejas Mk1 MRCA or on any other combat aircraft of the IAF or on board warship of the Indian Navy or on Pinaka-1 MBRL? Why is it that the SAGEM-built SIGMA-95N RLG-INS is on board the Su-30MKI, MiG-29K, MiG-29UPG, Tejas Mk1, Mirage 2000UPG, MiG-27UPG & Jaguar IS/DARIN-3? Why is the SIGMA-40 RLG-INS on board every Made-in-India & Made-in-Russia warship & submarine acquired or upgraded since the previous decade? Why is the SIGMA-30 RLG-INS on the Pinaka-1 MBRL’s TELs & also on the OFB-built 155X45 howitzer? <br />Regarding DRDO-developed ballistic missiles, the existing Agni-1s & Agni-2s are kept in a disassembled state in modules & are assembled only prior to actual launch. Which means the missiles’ QA/QC is dependent entirely on the proficiency of the SFC’s different sets of missile-assembly crew. Automatically, therefore, there’s loss of consistency in QA/QC levels. Had the missiles been canister-encased at an industrial facility, then & only then could QA/QC-levels be consistent & uniform without fail. Therefore, only with the arrival of canister-encased Agni-4 & Agni-5 along with the K-family of canister-encased SLBMs will there be assured & guaranteed fail-safe performance. Not until then & until then the only fail-safe WMD for SFC will continue to be the aircraft-delivered gravity bombs armed with unitary nuclear warhead. <br />Like I said, facts speak for themselves & jingoism never guarantees anything. For, merely producing a research paper on a cutting-edge product does not automatically translate into acquisition of core technological competency for producing such a product on an industrial scale.Prasun K.

But how many TRMMs are there in all?<br /><br />It is being claimed that AEW&CS S-band Active Aperture Array radar has a total of 1,244 individual T/R modules, based on a chart released by Astra Microwave.<br /><br />It is being said that these 1,244 elements may have been arranged into approx. 150+ TRMM units (8 each).<br /><br />So does this mean 200-watts output by a single T/R module makes the entire radar give a maximum power output of atleast 240-250kW?<br /><br />What is the power output of E-3 Sentry and Phalcon AEW system in comparison? A former French C4I expert on the forum has claimed<br />E-3 radar operates in megawatt-range (1,000+ kW).<br /><br />Are they right? What is your view on the whole calculation?K.

Just saw pics that some Kenyan troops during the mall siege were using guns that looked like multi calibre guns, but they were clumsy in adjusting the barrel section<br /><br />You say India is also looking for a multi calibre gun but if this type of clumsiness or difficulty remains while handling such guns then there is no advantage of such guns <br /><br />2. Just read an article that argued against the need for attack helos like AH64/LCH, arguments given say that attack helos cant be of any benefit whether IA/IAF adopt 'cold start' or IBG formations or in mountains along LoC/LAC owing to power & payload issues<br /><br />In that case i say that IA/IAF should and must go for V22s whose armed version can perform much better than attack helos as per power & payload issues in above mentioned areas and scenarios<br /><br />3. Regarding my previous answer i didnt mention 1979 or 2005 anywhere, you did; that means there is much merit in both cases<br /><br />4.
