India First To Build a Supersonic Cruise Missile 319

An anonymous reader writes with this excerpt: "India successfully tested Sunday a 'maneuverable' version of the BrahMos supersonic cruise missile which it has jointly developed with Russia, news reports said. The vertical-launch version of the 290-kilometer range BrahMos was tested from a warship in the Bay of Bengal off India's eastern coast, the PTI news agency reported. 'The vertical-launch version of missile was launched at 11:30 (0600 GMT) hours today from Indian Navy ship INS Ranvir and it manoeuvred successfully hitting the target ship. It was a perfect hit and a perfect mission,' BrahMos aerospace chief A Sivathanu Pillai was quoted as saying. 'After today's test, India has become the first and only country in the world to have a manoeuvrable supersonic cruise missile in its inventory,' Pillai said."

          It's not the first maneuverable supersonic CM either. Russian P-500 Bazalt missile was both supersonic and maneuverable and it entered service in 1973 (!). Brahmos is an adaptation of previous generation Russian missile technology, and not even the most advanced variant of that. Russians don't export their latest stuff, particularly the kind of stuff that if push came to shove could be efficiently used against them.

    The headline says, "India First To Build a Supersonic Cruise Missile". In order to even accurately reflect the article, it should read, "India First To Build a manoeuvrable Supersonic Cruise Missile". But even so, the article is wrong;

    from wikipedia, P-500 Bazalt

    The P-500 Bazalt (Russian: -500 ; English: basalt) is a liquid-fueled, rocket powered, supersonic cruise missile used by the Soviet and Russian navies. Developed by OKB-52 MAP (later NPO Mashinostroyeniye), its GRAU designation is 4K80[1]. Its NATO reporting name is SS-N-12 Sandbox. It entered service in 1973 to replace the SS-N-3 Shaddock. The P-500 Bazalt had a 550 km range and a payload of 1,000 kg, which allows it to carry a 350 kT nuclear or a 950 kg semi-armor-piercing high explosive warhead (currently only the conventional version remains in service). The P-500 Bazalt uses active radar homing for terminal guidance, and can receive mid-course corrections by the Tupolev Tu-95D, the Kamov Ka-25B and the Kamov Ka-27B.

    So many levels of fail in this submission

        A mass produced 350 KT V-1 from the mid 1940s would have been a quite effective strategic weapon. A modern version would probably work pretty well too.

        The definition game is probably best played by flight profile as opposed to navigation systems, in which case an ancient german V-1 would qualify.

    • by Anonymous Coward on Sunday March 21, 2010 @04:27PM (#31560364)

      I'm an aerospace engineer...in our jargon, a course correction compensates for drift, so we are talking about correcting for very low angular rates that come about because of gyro drift, winds aloft, etc. The engineers who designed the P-500 for course correction likely used small angle approximations (cos(theta) = 1, sin(theta)=theta -- first term from a Taylor series expension) because the correction values for theta were very small.

      A maneuver is a large deviation from the initial flight path, where theta (flight path angle deviation) is large enough that the first order Taylor series approximation does not work. What this means is that your controller becomes highly nonlinear, and requires significantly greater amounts of computing power.

        The missile, when fired in a swarm (group of 4-8) has a unique guidance mode. One of the weapons climbs to a higher altitude and designates targets while the others attack. The missile responsible for target designation climbs in short pop-ups, so as to be harder to intercept. The missiles are linked by data connections, forming a network. Missiles are able to differentiate targets, detect groups and prioritize

        The Russians have stricter export controls on anything with greater than 300km range. The Indian missile is intentionally limited to under that range to allow for continued technical support from Russia.

      Actually, AFAIK the Bazalt is maneuverable only during its cruise phase, once it reaches the terminal guidance track and goes supersonic, it isn't really more than marginally guideable.

      I'd guess that the Indian one is supersonic most of its range (thus the puny 300km) and will accept course guidance during supersonic flight.

      So no, I'd guess that the title is only misleading, not grossly wrong as you imply.

They fly circuitous routes to avoid detection and generally fly at lower altitudes to avoid radar. If launched at missile silos they can effectively wipe out all nuclear offensive capability thus rendering an enemy helpless.

          The speed is of no account for surprise attacks because you just do ToT Time on Target calculations to stagger the launches. Besides alternate delivery is much cheaper (UPS, fedex, the local trucking company)

          So, a SS CM is only useful for very fast delivery, very low latency missions... more the response to the surprise attack than the surprise attack itself.

      Weapons like the BrahMos are primarily aimed at ships. Yes, you could also use it as a precision-guided land attack cruise missile, but Pakistan's navy is small and almost irrelevant for conflict with India.

      This weapon - and, indeed, much of India's military development - is about maintaining military competitiveness with China, and to some extent the ability to discourage the US from interfering if India conducts military operations in areas it regards as its sphere of influence.

      The US Navy is apparently upgrading its cruise missile defences on its ships, replacing the Phalanx gun-based system with a missile-based version, because of missiles like the BrahMos.

        The phalanx has been going away for decades. In fact, it was conceived as a stop-gap system that was only supposed to be around a few years because the Rolling Airframe Missile was (badly) late.

        Personally, I don't see why something like Phalanx wouldn't be the right system to use against really fast missiles. The energy released when a DU bullet hits a missile coming in at mach 2.8 (or mach 5.2 for Brahmos II) must be absolutely enormous. Sure, you'll get crap all over the deck, but that's not the end of the world.

          Because of the engagement envelope. It's very, very tiny. Against a supersonic target it would be a second or two at most. Scoring a critical hit against a cruise missile doesn't do much good if you do so only a hundred feet out. In the Falklands War, the Brits almost lost a ship to a dud Exocet. The warhead didn't go off but just the impact and burning fuel was almost enough to sink the ship. Just how bad could this be? I don't think we've ever conducted live fire tests. We really should.

          Your primary defense against incoming cruise missiles is blowing them up before they're launched, be it ground or air-based. Failing that, your next best bet is knocking them down at range with your SAMs. A CWIS system is only meant to be the last line of defense.

    Isn't this just a really fast surface to surface missile? The operational range is 1/10 of a Tomahawk. How is this any different from a short range ballistics missile, other than the trajectory? I don't mean to criticize an impressive achievement but I foresee it being very different in use from something like a Tomahawk. A Tomahawk can be fired from a huge standoff range and hit its target. With this missile, the attacker has to get relatively close to its target, thus making it vulnerable to defenses. A big part of the value of a cruise missile is that the attacker can stay relatively safe. I think this weapon is much more defensive in nature and this is perhaps a reflection of India's strategic outlook.

The Brahmos (and earlier versions like the Russian P-800 Onyx) have a different strategy - it's a lot easier to pick up on radar and IR, but you don't have a lot of time to knock it down.

      The advantage of a flat trajectory over ballistic is two-fold: 1) cruise missiles are easier to make than ballistic missiles.

Oh and the newfangled ability to construct WMD. Exactly as Einstein said, we've left the cave in terms of ability to manipulate the outer environment, but haven't caught up in our value systems nor our maturity. Whether we just cannot see the forest for the trees and therefore even our modern abstractions of values and worldviews are extensions of the original survival of the fittest trait generation is to be seen but is perhaps irrelevant in that we now are capable of a conscious choice, irrational or not.

        To choose to act toward the benefit of all mankind or even all sentient life may not seem rational in a closed system.

    Russia built a series of supersonic anti-ship missiles with ranges in the cruise category. They were mostly fit aboard submarines and destroyers and designed for saturation attacks, which our missile defense systems were poorly equipped to deal with.

    Using modern technology (higher temperature alloys, ceramic composites, and CFD optimization) it would be easily possible to build a cruise missile in the 1000nm range. In fact, because subsonic cruisers have to combat with launcher dimensions, their form factors are ill-suited for subsonic drag reduction and supersonic missiles might have an aerodynamic advantage.

    ATK is currently developing a hypersonic cruise missile for the 800km range, which is an important gap filler between what artillery, short-range missiles, and ballistic missiles can hit quickly. This range is currently filled by subsonic cruise-missiles which can take over an hour to reach the target. Time-critical-strike it's called.

    The issue with a supersonic cruise missile is that it needs even more than a subsonic cruiser to fly at high altitude in order to achieve satisfactory range. Aerodynamic heating is difficult, perhaps limiting at low altitudes for more than a short terminal phase. Flying at high altitude means they are easier to detect (not that look-down-shoot-down isn't standard, but ship-based phased-array radars won't be looking down) albeit harder to intercept due to their higher velocity.

    What's really scary are the Chinese developed anti-ship ballistic missiles [wikipedia.org]. Stealthy re-entry vehicles that can perform course changes. This is an interception nightmare and likely driving the US Navy ballistic.

The unfacts, did we have them, are too imprecisely few to warrant our certitude.
