| recent: il est temps de voir arriver les MM40 block III! citation: BrahMos delivered to Navy (Santosh Patnaik) VISAKHAPATNAM: Supersonic cruise missile BrahMos was delivered to the Navy here on Thursday. The event was celebrated at INS Kalinga on Visakhapatnam-Bhimunipatnam beach road. A. Sivathanu Pillai, Chief Executive Officer and Managing Director of BrahMos Aerospace Private Limited; Vice-Admiral Sureesh Mehta, Flag Officer Commanding-in-Chief of Eastern Naval Command; Rear Admiral (retired) S. Mohapatra, in charge of BrahMos missile delivery; and V. Bhujanga Rao, Director, Naval Science and Technological Laboratory (NSTL) were among those present. A top source in BrahMos Aerospace told The Hindu that for the first time, the missile, mostly produced indigenously in Hyderabad, has several unique features. Joint venture The BrahMos Aerospace Private Limited is a joint venture with Russia, in which India has a 50.5 per cent equity. The company designs, produces and markets the missiles. In the past three years, the missile had been successfully test-fired from Interim Test Range at Chandipur-on-sea in south Orissa. The missile will be integrated with various naval warships and shore-based complexes. The NSTL's efforts to design advance models of stealth ships received a shot in the arm with the launching of work on instrumentation radar centre atop Dolphin hills overlooking the sea here on Thursday. The centre, being developed at a cost of Rs.10 crores on a site allotted by the Navy, will be an advanced facility for measuring the radar signature of ships by the NSTL. Ships can evade attacks during hostilities if they are undetectable by enemy radars. The centre will help the NSTL in studying various stealth design features of ships. The new facility, expected to be ready by May next year, will help reduce radar signature of ships by using newly-developed stealth material. Laying the stone for the centre, Dr. Sivathanu Pillai said: "I know, a few years back, the NSTL embarked upon an integrated stealth technology programme. As part of it, it developed a lot of stealth hardware, software and stealth materials." He said some of the stealth materials developed by the NSTL and Mumbai-based Naval Material Research Laboratory (NMRL) were inducted on first of class stealth ship INS Shivalik. |

| oui, 180 km de portée contre 250 je crois, mais c'est quand même mieux que le MM40 Block II de 75 km, alors que l'Inde a déjà de nombreux SS-N-25 de 130 km |

| un peu de technique tirée du navire qui effectue les essais du missile: The forward P-20M missile cells (port and starboard) aboard INS Rajput have been replaced with two boxed launchers housing four PJ-10 (BrahMos) ASCMs. D51 served as the trials platform for the missile, which can be fitted with a conventional or nuclear payload of 200 kg. The missile has a range of ~300 km at 14,000 metres or 120 km at 10 to 15 metres. The missile is believed to have a first stage solid-fuelled booster and a second stage liquid-fuelled ramjet. |

ça n'est pas tous vrai. Le Brahmos a seulement cette porté quand il est en haut. Le MM40 est très difficile a trouver parce qu'il vole très bas. Le Brahmos peut voler très bas aussi, mais la porté devient seulement 160km... c'est encore beaucoup moins que 300km. Elle plus rapide que l'exocet, mais elle est aussi plus plus plus large et lourde. Normallement la même navire peut porter plus d'Exocets que des Brahmos... ça c'est la theorie! Quand le Brahmos vole en haut, il est très vulnerable, le Aegis est dévéloppe contre ces missiles. Aussi le Aster ne peut pas avoir des problèmes avec ça. _________________ There are more planes in the ocean than submarines in the sky

Vous avez raison. Brahmos produces more kinetic energy than a sub sonic cruise missile. Sheer impact will cause a lot of damage, followed by the warhead.
Neptune,
Brahmos has 290+ kms in Hi Lo Hi flight path. It has around 120 + kms range in lo lo lo combination. It is sea skimming and rises above sea level just 6 seconds before hitting the target. Even if there is a intercept, the sheer kinetic energy of fragments will impact the ship. Sub Sonic missiles have a lesser chance. However except US, no one has anti-Supersonic cruise missile capability. US has practiced against Hawk missile with Ageis, but still it is not a 100% kill. |

| Pas toutes vrai. L'horizon radar est environ 30km. L'exocet vient la a 2min 20secondes, le Brahmos vient là à 36secondes. Jusqu'a l'horizon radar tu peux voir tous ce qui est là, a altitude 0. Quand le Brahmos vole bas, qui est le mieux, la porté devient moins que l'MM40 bl III. La tête explosive se défragment quand le Brahmos est intervenu, elle n'explode plus après ça. Les fragment ne sont pas dirigé et peut être elles casse quelque part de coque, mais ça n'est pas important ni une problème pour le bateau. Le US a Aegis contre des missiles supersonique, mais aussi le Japon, Espagnol, Norvège et Corrée de Sud ont les bateaux Aegis. L'Aster a aussi la capabilité d'intervenir un missile supersonique et maintenant, la France, Royaume Uni et l'Italie ont l'Aster, ça fait déja quelques pays... Aussi la Russie a cette capabilité avec le Tor et le S300F/FM. _________________ There are more planes in the ocean than submarines in the sky

| JollyRogers, Thanks for the translation Neptune, I have already told you US "could" intercept it with Ageis. A horizion radar cannot detect anything thats sea skimming. Please provide me the necessary proof for it. Aster can counter supersonic CM? Is there data to support it? What missiles have they practiced against? |

| I will respond to you in English. A "Horizon Radar" is not what I meant, well it's French. It just means Radar Horizon (strange Frenchies). And within your radar horizon you can see anything down to the waves. By flying low, you stay longer below that radar horizon, but once you reach it (at approx 35km from your target) you're visible. Hardly so, but still visible. Anyhow, what I mean is that you want the best chance of intercept with your missile, this means that you'd want to launch it in lo lo lo mode. This means that, when you are at 140km with Brahmos, you will wait and close in to 120km. At that moment, at 140km, the Exocet can already be launched, which will force you to fire Brahmos in Hi Lo Hi. This on its part decreases your chances of success a lot. Aegis was developped against the Mach 2-4 attacks of the Kitchen missiles fired from Backfire bombers. Brahmos is little and lightly armed compared to those beasts. If it was developed against such, then I'm pretty sure it can intercept Brahmos with a big chance of succes. You're never sure you'll intercept it, you're not even sure you will intercept Exocet or other slow flyers with Aegis, but the chances are big nonetheless. _________________ There are more planes in the ocean than submarines in the sky
