    Shooting down their aircraft is a bonus.

    By forcing the enemy aircraft to fly lower, their range/combat radius is diminished and they are now exposed to all sorts of short range air defense systems.
    So, the 400km range of the S-400 has already reduced the effectiveness of the enemy airstrike... without even firing a missile.

    400km is the missile engagement range, detection range is around 600km, if i recall.

    Does the U.S. potentially have an advanced secret weaponry with which to counter at least some of Russia’s advances in hypersonic missiles?

    How to defeat Hypersonic threats? - Page 3 Empty Latest Idea

    Post  calripson Sat Feb 12, 2022 4:21 pm

    The latest idea is to create an aerosol covering of particles that would destroy a hypersonic warhead. Don't know how practical that is. Might not work on a windy day.

    The "aerosol" would have to be ball bearings. Any actual aerosol even if made out of metal particulates would not stop a warhead. At best it would
    cause some ablation. The term aerosol has a specific meaning in terms of physics and it is not just lumps of matter in air.

    Highly unlikely because Russian strategic warheads incorporate aerosols/cosmosols in their design lmao!  If that's HATO's new strategy than..... lol1 Razz Embarassed clown pwnd

    Lasers are probly the only option at the moment.
    Deploying a number of those systems to your various bases is the only real move nato could make.

    Cons to this are that they defenitily aren't gonna be mobile and of course say goodbye to your defenses if the powergrid go's out, i doubt they can deploy big enough backup generators to support those lasers.

    And guess who supplies europes powergrid with gas.

    Lasers are scifi hyped weapons. Their energy is nowhere near instant melt or vapourization level.

    Non-ballistic missiles frustrate lasers just like they frustrate missile interceptors. The targeting mechanism
    cannot predict their path and even if the stepping motors aiming the laser can achieve rapid target lock,
    the precious fractions of a second cost much in terms of heating of the target. The need to paint the target
    for long enough to do damage to it is a show stopper for this approach.

    Reagan's SDI faked laser ICBM interception potential in static ground tests. They could not even achieve
    burn through under ideal conditions without hacking a local re-focusing. What a joke.

    There is a physical constraint on lasers that are not of the Teller nuclear bomb one time use only variety.
    They have to be weak enough not to destroy themselves. The lasing requires resonating the light beam in
    what amounts to a mirror chamber (which can be a solid crystal). A laser powerful enough to varpourize
    targets will also vapourize itself. The answer to the question as to why any laser can do any sort of melting
    of targets is that the target is absorbing the photons while the laser is not absorbing enough to melt itself.
    This shows up as the time it takes to melt the target and its absorption properties. A highly reflective
    coating will defeat the laser on any time scale that matters. If you want instant melt, then the photon
    density required is so high that even marginal self-absorption by the laser will destroy it.

    The core problem is that a scramjet powered weapon is going to be flying as high as it can practically... and what limits the height of clouds would also limit the effective heights clouds could form and remain at for any period of time...

    Currently rocket powered Kh-32s operate at 40km altitude... I would be surprised if Zircon operated lower than that, because very high altitude means low drag... the air would be very thin but the enormous speeds the missile is flying at means a decent volume of air would be going through the engine to compress heat and burn...

    Lasers are probly the only option at the moment.

    Not really viable... the target would need to get too close for it to be effective... most ground based battlefield lasers hit targets out to 2-3km or so with enough energy to bring them down... that would mean it starts to get effective one second before impact which is not really long enough to destroy it reliably and have the wreckage disperse enough to not do any damage.

    I would say long range SAMs like SM-6 fitted with a nuclear warhead flown into the path of incoming threats and then command detonated would be their only defence... which is probably going to upset a few allies... who might get to see a real firework display.

    Obvious problem is that all these nukes going off relatively high up in the atmosphere is going to seriously effect the radar performance of ground based systems against the next wave of missiles...

    Pentagon hypersonic military technology tests failed 3 times in a row

    To date, the United States has more than half a dozen hypersonic weapons systems in development, but none of them have been put into the field.

    In 2017 and 2019, Russia and China, respectively, deployed their first hypersonic capabilities, with other nations, such as North and South Korea, France, Japan, Australia and India, researching the new class of weapons.

    For the third time in a row, Lockheed Martin (giant of the US military branch) failed to launch a new hypersonic missile for the US Air Force. The situation has brought concern and embarrassment to the Pentagon and Congress because it is not expected to meet the deadline to start production of the hypersonic weapons system by September 30.

    The Air-Launched Rapid Response Weapon (ARRO) is a hypersonic thrust missile that is to be placed aboard the B-52H Stratofortress and B-1 Lancer strategic bombers, and its specifications include an operational range of 1, 600 km and a maximum flight speed of about 6, 860 meters per second (Mach 20).

    A spokesman for the Pentagon's Department of research and engineering told Bloomberg that while its director had "supported the intense efforts of the Air Force to accelerate development," the September 30 deadline was a "very aggressive schedule."

    Congressman Jim Cooper, chairman of the House Strategic Forces Subcommittee, also expressed doubts about the program. "The U.S. has a long way to go to catch up with China. It will take much more than a September 30 press release to regain the leadership we have wasted since the 1970s," he said.

    The lawmaker emphasized that U.S. hypersonic programs in general need more " funding, engineering excellence, and rapid testing to start parity."

    "Even so, I worry that the U.S. doesn't even know how to catch up, mainly because of the repeated failures [that] we've had so far in components that shouldn't be technically challenging," Cooper said.

    The Air Force assured in a statement that" it is still possible "that the initial operational capability will be achieved on time,"provided that future flight tests are completed according to the current plan." Despite the failure of previous tests, the Air Force maintains that the test program "successfully demonstrated several events for the first time."

    The Pentagon froze plans to order the first 12 ARRO missiles in January due to test failures, emphasizing that it "would not grant a production contract without a production readiness review and a full-round test flight [which ensure the system's functionality without incident] successful."

    This is fine

    Meanwhile, Lockheed Martin indicated that nothing was wrong and that development is taking place as planned. "The joint government and Lockheed Martin team closely review all tests to ensure that quality measures remain in place," said company spokeswoman Cristina Vite. The missile " continues to gain significant technical maturity while accomplishing many milestones for the first time," the spokeswoman added.

    The fourth and fifth tests of the ARRO, in which its booster engine will be evaluated, are expected to take place by the end of June, with at least US.1.4 billion (about R 5 5.18 billion) expected to be injected into the project before the "initial operational capacity" is reached (above the previous cost estimates of US 4 480 million or R R 1.78 billion). More tests are expected between July and September of a fully operational missile.

    Along with the ARRO, U.S. defense contractors are involved in the development of at least six other hypersonic systems, including an Army-Navy common hypersonic slip Corps (Chgb), a Navy intermediate conventional rapid attack weapon (CPS), a long-range hypersonic weapon (LRHW) for the Army, the Hypersonic Conventional Strike Weapon (HCSW), and the concept of a long-range weapon.hypersonic air breathing (HAWC), both for the Air Force, and the Defense Advanced Research Projects Agency (DARPA) operational Munitions Program.

    The Army made the headlines when it announced it would begin putting the CHGB into the field last year, receiving the first components of its first CHGB system in October, including a battery, operations center, launcher carriers, trucks and trailers. Crucially, however, hypersonic ammunition for the system has not been delivered and is not expected to be produced until fiscal year 2023.

    Russia became the first country in the world to field a Moderna hypersonic weapons system, putting into service the Kh-47M2 Kinzhal air-to-ground aerobalistic missile with nuclear capability in December 2017. The existence of the system was revealed in a presentation by President Vladimir Putin in March 2018.

    China followed suit, making the hypersonic glider vehicle DF-ZF operational in October 2019.
    Russia achieved a breakthrough in its hypersonics program by taking the dust off Soviet – era research in the early 2000s, after the United States unilaterally withdrew from the 1972 Anti-Ballistic Missile Treaty-which imposed severe limitations on the creation of ballistic missile defense systems.
