Russia Tests World's Largest Non-Nuclear Bomb

mahesh_gharat writes "Russia has tested the "Father of all bombs," a conventional air-delivered explosive that experts say can only be compared with a nuclear weapon in terms of its destructive power.The device is a fuel-air explosive, commonly known as a vacuum bomb, that spreads a high incendiary vapour cloud over a wide area and then ignites it, creating an ultra-sonic shock wave and searing fireball that destroys everything in its wake."

    The Buran may have been cosmetically almost identical to the Space Shuttle, but functionally, the two couldn't have been more different.

    Look at their feature sets, among other things- the Buran was designed later, had quite a few key design decisions made that increased its design effectiveness immensely, and, sadly, never really flew.

    If the Soviets copied it, they did it by taking pictures of the outside and them using their imaginations to fill in what they thought the inside looked like.

  3. It's nothing like a nuke by Von+Rex · · Score: 4, Informative

    Comparing these things to nukes really underestimates the power of a nuke. Consider the wikipedia entry on the Moab.

    It's got a yield of 11 tons of TNT. That means the Hiroshima bomb, at approximately 15 kilotons, was about 1300 times stronger. And a Minuteman ICBM, at 1.2 megatons, is 109,000 times stronger. The Tsar Bomba weapon had a yield equal to about 40 Minutemen, or around 4.4 million Moabs.

    I know there's additional factors when it comes to amount of destruction inflicted, but still, it's clear that these fuel-air devices are a drop in the ocean compared to a nuke.

    The phrase "weapon of mass destruction" annoys me because it equates so many lesser things with nukes, which are, in my opinion, the only WMD, other than perhaps a really vicious plague weapon the likes of which we haven't yet seen.

    Seriously though, Russia has for many decades going back to just after WWII had a predilection for one upping the West in terms of military hardware.

    I'm not sure they've really one-upped the US here.

    This is a fuel-air bomb. It would be physically almost impossible for it to have the raw destructive power of the high explosives in the MOAB. Predictably, there are no actual specifications listed for the bomb in the Bloomberg article (ok, I didn't read it all the way through, but usually those things are at the top), just vague assertions like it being the "most powerful fuel air bomb" and "four times more powerful than the MOAB". That could mean a bunch of different things - it has four times the vacuum power? A four times larger radius pressure wave? (Note that fuel air bombs often have larger but slower - and therefore less destructive - pressure waves.) It doesn't mean that it has four times the explosive power of the MOAB, because that would be pretty ridiculous.

    Fuel air bombs look really impressive when they explode but they don't do a hell of a lot of damage. They mostly just char a lot of stuff and clear the area of life. High explosive bombs like the MOAB, by contrast, are just the opposite - they don't look very impressive (no big mushroom cloud) but they do massive amounts of damage. If you're anywhere near a high explosive bomb when it goes off, you may not get burned, but you will end up in about a thousand different pieces, as will everything else around you that isn't buried 100 feet below the ground.

    Nuclear bombs sort of combine the worst effects of both high explosive and fuel air bombs. But if you're going for destructive power in a non-nuclear bomb, a fuel air bomb is not what you want to use.

    Kh-15 is a supersonic, short-range attack missile carrying a 200-kiloton nuclear or 250 kg conventional warhead. It was designed to provide Soviet medium- and long-range bombers with an outstanding strike capability against targets protected by sophisticated air defense systems. This can be done thanks to its impressive maximum speed of Mach 5. Kh-15 guidance system is based on the inertial navigation and may be backed up with a radar homing head for anti-ship applications.

    Kh-15P designation refers to the anti-radiation version of Kh-15 which is a superb weapon for enemy air defenses suppression. Kh-15A and/or Kh-15S refer to an anti-ship variant. The Russian/Soviet Air Force deployed the Kh-15 on its Tu-160, Tu-22M and Tu-95 bombers. NATO calls this weapon the AS-16 Kickback. It is the Soviet counterpart to US AGM-69 SRAM.

    It doesn't mean that it has four times the explosive power of the MOAB, because that would be pretty ridiculous. I don't think there's any reason why it couldn't, if by "explosive power" you mean energy release. The Russian device in question is only slightly smaller in size than a MOAB, and probably uses newer, more powerful explosives. Just on those grounds alone, its energy yield is probably about the same or larger. (The fact that the bomb is designed to disperse the explosives into a cloud and then detonate them -- a Fuel Air Device rather than a conventional integrated-mix explosive -- probably doesn't change the energy yield much but has more of an effect on how the blast is actually delivered.)

    Fuel Air Devices aren't really that interesting, from a fundamental engineering standpoint. Scaling them up isn't that hard -- you just add more fuel. Eventually you run into delivery problems. Like the Tsar Bomba (the Russkies giant H-bomb), it's more of a question of priorities than design ability. You can scale a hydrogen bomb up pretty much arbitrarily, by adding more tritium; similarly, FADs can be made bigger simply by adding more fuel and then changing the dispersion calculations accordingly (so that you achieve the right fuel/air mix at the right target altitude). The real question is 'why would you bother?' It's probably easier to drop twice as many bombs of half the size, than one really monster bomb, in most combat scenarios.

    I don't really doubt that you could make a FAD that's bigger than the MOAB. They have more real-world experience in the area than other nations -- they used FADs extensively in Chechnya -- and have shown a propensity in the past for building "the biggest" simply for the penis-length factor. That doesn't mean that the rest of the world should be rushing out to do the same thing, or really care.

    Yes, during WWII it was actually quite common for planes to attack surface ships with iron bombs, or even just strafe them with machine gun fire. That became problematic with the availability of air cover from aircraft carriers and better ship-mounted defensive systems, so it went out of style until cruise missiles were developed and standoff attacks were made possible.

  9. big bombs vs terrorists/freedom-fighters/whatever by TTK+Ciar · · Score: 5, Informative

    Can you really fight terrorists with giant bombs?

    The Russians seem to think so.

    In 1999, the Russian Army evacuated the city of Grozny of civilians, leaving (obstensibly) only the dug-in insurgents in the city. Russian forces then cordoned the city and laid waste to it with massive barrages of fuel-air munitions, delivered via TOS-1. The city was totally destroyed.

    That was using Fuel-Air Explosives (FAE's), which use aerosolized hydrocarbon-based fuel. Judging from the mass-to-yeild ratio reported for this new bomb (~5.5x that of TNT), it's an aluminum-based thermobaric munition. Thermobarics use aluminum (or less commonly boron) based fuel, distributed and usually detonated by high explosive charge. Compared to fuel-air bombs this results in greater reliability, more energy released per unit mass, and much more energy released per unit volume (since 75% aluminum + 25% composition-B HE is about 2.5x denser than hydrocarbon-based fuels).

    For what it's worth: (1) the old-generation american fuel-air explosives used ethylene oxide as their fuel, which increased reliability but at the expense of energy density. (2) the american armed forces have aluminum-based thermobaric munitions in their inventories, too.

    And yeah, comparing FAE's and thermobarics to nukes is misleading. Thermobarics can offer up to ~8x the energy density of conventional high explosives, but even small nukes generate thousands times more boom per unit weight. Nukes are the cheap and easy way to destroy a city, but the Russians decided the political price would be too high, and used FAE's instead (which are much cheaper than equivalent-yield high explosives, but nowhere nearly as cheap per unit yield as nukes).

    Except for one little problem - the Russians didn't have any small fast aircraft that could strike naval battle groups in the GIUK, let alone deep in the North Atlantic.

    I would. A aircraft that can cruise at mach 2.35 and dash at 2.8 making it immune to most threats. Carries multiple long range missiles coupled with a powerful radar. Can take off and land from a dirt strip while being maintained by semi-skilled conscript labour and flown by relatively unskilled pilots counting on its excellent autopilot. Plus cheap enough to mass produce. And all that in the sixties! The Foxbat is an outstanding success outside of Tom Clancy novels.

    Yes, the jets may of been able to out run the F-15's of the day, but their maintenance requirements were extraordinary

    Actually they werent. No more than say the F-14. The soviets just had a different maintanence philosophy.

    A high speed run above mach 2 required them to be fully rebuilt. A high speed run above mach 2.8 for more than a few minutes generally resulted in the destruction of the engines.

    Routine mach 2 flight did not result in the engine having to be being rebuilt.

    That, coupled with the Mig-25's short effective combat radius (~180 miles with full load out), poor maneuverability (typical G loading limited to around 3 depending on fuel and load out), doesn't make it an effective interceptor.

    I don't know where you are getting your numbers but MiG-25 with four missiles and some supersonic flight (few minutes in combat) had a range of about 600 miles. Range under full load is a meaningless term in real life. At maximum weapons load a F-16 runs out of fuel by the time it taxies for takeoff. It doesn't mean that F-16 is a ineffective aircraft in real life.

    And poor maneuverability is a quite acceptable limitation for a interceptor. These aircraft are not intented for dog fights.

    Mig-25's have kills associated with their name, but none have ever intercepted an SR-71 (one task it was designed to handle)

    Actually it wasn't designed to intercept the SR-71, but the high altitude fast bombers like the B-58 and B-70 which it was more than capable of doing.

    In a head on engagement (ie, F-15), their only defense is their speed

    You mean other than their longer ranged missiles or their electronic warfare gear?

    which results in massive maintenance or destruction of the engines.
