    Meanwhile the Russians already have Peresvet that's 1-10 MW, on top of that it's a MASER and a GRASER.

    10MW is a huge output . Please share a source .

    What kind of input , nuclear ?

    Check the Peresvet thread, it's been confirmed for years now that it's nuclear powered, and specifically it's a nuclear pump-laser:

    In this case, the output optical power of Peresvet BLK can be estimated in the range of 1-3 MW with the prospect of increasing to 5-10 MW.

    With investment in time its performance will improve.

    The US land based ABM system was not really that scary, but later versions and improvements were moving towards something that might be destabilising before they changed it.

    Having a system in service is step one... even if it is not that powerful now... over time improvements in performance and power generation will make it a gradually more and more effective weapon.

    It will suffer from all the same problems other laser suffer from... primarily range... and generating enough power... but over time solutions are found... for instance previously nothing from ground based telescopes looking at the stars could compare with a space based telescope but then they started using active lenses that reduced the effect of the atmosphere on the light arriving from space and so the images got radically sharper... the same technology could be used to help a laser beam go through it more easily too... now that they have a system in service they will start looking for solutions to make it better... and it will get funded because it makes an existing system better...

    The US railgun projects have fizzled out with little fanfare. There is no renewal of funding for the next fiscal year. A while back
    there was lots of hype how projectiles were accelerated to Mach 6 and how these guns would be equipped on the Zumwalt, etc.
    The question is whether these claims were nothing more than propaganda BS. Any country can set up a rail gun demonstrator
    and accelerate a projectile to Mach 6 and even faster. The problem is the practicality of these guns and what is needed are
    working prototypes nearly ready for deployment.

    I think there is something fishy with these wunderwaffen. A warhead can be accelerated to Mach 10 by the Kinzhal anti-ship
    missile. It uses a certain mass of chemical fuel that is used mostly to carry itself and not just the warhead thanks to gravity. A
    rail gun does not need the extra energy to fight gravity. So how is it that a whole power plant is needed to operate a rail
    gun sized for a ship and shooting projectiles much smaller than the Kinzhal warhead? Supposedly even a carrier would not
    easily accommodate such a powerplant. The issue is energy delivered per shot and not total lifetime of gun energy expenditure.
    Things don't add up.

    So they spent a half billion just for a prototype Shocked

    They could better modify those hypervelocity projectile to launch it from the 127mm powder guns . It will be with a lower speeds than railgun but at least a development to something practical and ready for service on their dicks .

    The US and the French made the same mistake on land where they decided they wanted tank gun launched missiles, but in both cases they made the same mistake of developing the missile first which meant the guns were unique never used before or since guns whose ballistics were totally wrong for launching anything but these custom designed missiles.

    The French missile was a 142mm calibre weapon which they cancelled pretty quickly, while the American missile was a 152mm calibre weapon in a military where the closest similar calibre is 155mm calibre and totally different and not compatible.

    The large calibre meant the gun fired a missile which was impressive on paper and was taken into combat multiple times but never achieved a kill or that many successful launches.

    The only other round it could fire was a big heavy very low velocity HE shell similar to a demolition charge for engineer vehicles... except the vehicle was supposed to be a missile carrying tank destroyer for which a demolition charge is essentially useless with very short range.

    The final conclusion of the US programme that included the airborne Sheridan tank and the M60A2 tank with these 152mm guns was that although on paper the missile performance was excellent the cost was enormous and in practise it didn't work and using an M113 APC vehicle with a TOW missile launcher on its roof was cheaper, simpler, vastly more effective in the sense that it worked and worked relatively well.

    The Soviets did have a similar project that also failed but actually entered service and was made obsolete fairly quickly... it was the IT-1 and IT-2 missile tanks that did away with a tank gun barrel and was just a squashed T-62 tank with proper tank armour and a missile launcher that actually worked.

    In parallel they also identified the problems with accuracy against long range targets... the main problem being a moving target can move in unpredictable ways between the time when the round leaves the muzzle of your gun and when the round arrives to the target... no level of gun precision can remedy that because it is not about gun precision, it is about moving targets not being predictable at greater and greater ranges.

    The solution was a guided round for all tanks which is what they proceeded to develop including for their older tanks and their newer tanks.

    They had one missile that could be fired from the rifled 100mm gun of the T-54 and T-55, a modification of that same missile that could be fired from the 100mm rifled gun of the BMP-3. A further version that could be fired through the smoothbore 100mm MT-12 anti tank gun, and a version that could be fired in the 115mm smoothbore gun of the T-62.

    All four of these missiles had different propellent arrangements for the different types of rounds each of these guns fired and they could be carried and stored as standard rounds of ammo except for the BMP-3 round which had a special loader because the missiles were several times longer than the small standard HE rounds.

    The point is that these missiles were not intended to be the only ammo carried, they were another type of ammo that could be carried for specific targets like long range shots at armour or for use against helicopters.

    The 125mm round eventually evolved into the Svir which is laser beam riding and cheap and simple and very effective and could be loaded in the autoloaders of the T-64/72/80/90 and Sprut and towed 125mm guns that fired it...

    It is treated like a standard round of ammo but can hit moving targets at 5km with a probability of more than 90% with an autotracker... which is built into the optics upgrade required to use these rounds.

    The point is that you don't make a super round and then make an expensive different gun to fire it, you take a standard calibre that allows you to use all your existing other rounds, but also this new round with its new capabilities that can then be used across your existing fleet and improve performance across the board simply by putting that round in mass production.

    What they did with the Zumwalt was make three unique guns that are operational only on three of their ships.

    At about 800K per round they are actually not much cheaper than a Tomahawk missile which has 1,500km range and a much heavier payload and is already in widespread USN service.

    What they should have done was take an already in use calibre... 127mm is probably too small... perhaps a new 155mm or maybe a 203mm gun that they can make a range of standard rounds for so even if the new rounds lack performance it is still a useful piece.

    They can then work to improve performance... even if it takes 5 years it does not matter... they would get something useful in the end.

    The Russians have used a joint development with the 152mm Coalition between the Army and the Navy to develop a 70km range gun that fires standard rounds with smart fuses and guidance kits to achieve a CEP of 10m at 70km range and with the potential to reach 180km in the future... that is vastly better than their existing largest naval calibre of 130mm which is used at sea and on land in their Bereg coastal defence guns.

    The heavier shell weight and greater range and amazing accuracy from a mass produced round is ground breaking... literally... and both their Army and Navy will benefit directly from this.

    Would love to see them put 152mm guns on their new destroyers and upgraded cruisers, and perhaps a new 203mm gun for new cruisers down the line... the Russian Navy could probably use a heavier calibre.

    To be clear 152mm is a useful round with a 40-50kg shell, but a 203mm round with a 110kg shell is like delivering a light aircraft delivered bomb with each shot... and of course navy guns can fire rapidly and carry a lot of ready to use rounds for shore bombardments.

    They might keep the 152mm guns for new destroyers and new cruisers and perhaps put 203mm guns on specialist naval gun support ships intended to support landing operations... perhaps on their new 40K ton helicopter carriers could have 203mm guns perhaps with a 150km firing range to start with and perhaps 250km with lighter rounds like the new rounds for the 152mm guns firing 180kms...

    The Army and Navy can share the costs and essentially they both want the same thing... long range accurate powerful artillery fire that is cheap to deliver.

    These are the five technologies that the US should develop to remain a superpower, according to a report from its own Intelligence, 24/10/2021.

    The U.S. National Center for Counterintelligence and Security fears that U.S. companies could be completely expelled from the technology sectors crucial for the 21st century.

    According to a report from the U.S. National Center for Counterintelligence and Security quoted Friday by CNBC, to remain a global superpower Washington must continue to maintain leadership in artificial intelligence, quantum computing, bioscience, semiconductors and autonomous apparatus systems.

    "These sectors produce technologies that can determine whether the US remains the global superpower or whether it will be overtaken by strategic competitors in the coming years," reads the document. U.S. intelligence expresses concern that U.S. companies could not only lose their advantage, but could be completely expelled from the technology sectors crucial for the 21st century.

    The report considers that China " possesses the power, talent and ambition to potentially surpass the US as a global leader in artificial intelligence in the next decade if current trends do not change." At the same time, he points out that Russia also has its ambitions in this field.

    Intelligence officials argue that the winner of the race to develop quantum computers will have a tremendous strategic advantage. "A large-scale quantum computer could potentially allow the decryption of the most commonly used cybersecurity protocols, putting at risk the infrastructure that protects economic and national security communications," says the U.S. National Center for Counterintelligence and Security.

    Intelligence officials stress that it is of integral importance to take steps to lessen the US's growing dependence on foreign biotech companies, which are increasingly gaining access to US intellectual property in the field of bioscience.

    The fragility of the semiconductor industry has manifested itself recently, the report says, in addition to specifying that the U.S. is heavily dependent on a single company in Taiwan. At the same time, it notes that adversaries can access the supply chain and place compromised chips in US commercial and defense systems.Given these circumstances, the country should pay particular attention to the semiconductor sector.

    The paper concludes that autonomous systems also present a potential security threat, in the event that hackers exploit their vulnerabilities and collect a huge amount of data about US citizens and companies.That is why the nation must ensure its dominance in this sphere.

    The United States is already lagging behind in many military technologies. The first example is hypersonic missiles.

    Peresvet has lit the fire under yanqui rears and now they are running around claiming to be developing the "number 1" battlefield laser.
    In 2014 they already claimed to have such a device which was in the 30 kW range. Now they are trumpeting a 300 kW range system.

    The previous wonder weapon was painted as the ultimate achievement even though it was tested on targets like the 1980s SDI hoaxes.
    For example it was used to take out a plastic model less than half a meter in size at a range of 20 meters running on a wire. This joke
    was supposed to represent real world effectiveness against large metallic drones at a vastly greater ranges.

    The new wonder weapon is supposed to take on Chinese hypersonic missiles (as if Russia does not have any). This is the biggest
    joke since the previous wonder weapon was never deployed and did not have a demonstrated cooling system that would allow it
    to survive multiple uses. Cooling is a serious issue for lasers even in the 30 kW range. So a system ten times more powerful requires
    even more effort at cooling. The other show stopper for an anti-hypersonic laser is that it needs ridiculously precise targeting mechanics.
    Tracking an over Mach 8 object from a long range (tens of kilometers) is not easy. ABM rockets rest on continuous course adjustment
    for interception and thus converge on the target. Also, all lasers have a problem with beam dispersion. They are not fundamentally
    parallel photon emitters but bounce photons between internal mirrors with a small aperture. Or they use fiber optics wire bundles to
    produce an aggregate beam, but the photons coming out of each fiber cable still have scatter.

    This latest laser project from the US is yet another "raspil" (budget raid) by private contractors like Musk who are enabled by rotten politicians.

    Peresvet is likely effective as a satellite blinding system. But pew-pew lasers are for scifi fanbois who never got the qualifications to understand
    that fantasies are not reality no matter how hard they want them to be.

    It is a first generation system, but over time it will be improved and upgraded and its performance and capabilities will expand and it will be more than just a dazzler...

    The possibilities of Peresvet are shrouded in mystery.  Apparently, its power is over 1MW.  Compared to American toys, that's a lot.  It is now a fully operational system.  Russia is far ahead of the US in laser technologies.
