    Winning The Salvo Competition: Rebalancing America’s Air And Missile Defenses

    Winning The Salvo Competition: Rebalancing America’s Air And Missile Defenses

    Over the last fifteen years, the Department of Defense spent more than $24 billion buying a mix of capabilities to defeat guided missile threats to U.S. and partner naval forces and land installations. Despite DoD’s urgency, these investments have not resulted in air and missile defenses with sufficient capacity to counter large salvos of ballistic missiles, cruise missiles, and other precision-guided munitions (PGMs) that can now be launched by America’s enemies. This situation is partly the result of DoD’s longstanding emphasis on fielding costly, long-range surface-to-air interceptors to defeat a small salvo of anti-ship cruise missiles or a handful of ballistic missiles launched by rogue states such as Iran and North Korea. It is also because the U.S. military has never fought an enemy who had the capability to strike distant targets with precision. In future conflicts, however, America’s opponents can be expected to employ large numbers of sea-, air-, and ground-launched guided weapons to overwhelm limited defenses now protecting the U.S. military’s forces and bases.

    The Pentagon has ordered construction of new facilities for the US Missile Defense Agency in America and a number of countries around the world, the Department of Defense announced.

    More pork for the US defence companies...

    And the result is that Americans will feel safer, but how will it stop such things being targeted directly... I mean an airship with a powerful radar constantly scanning looking for threats should be a trivial target for a high flying ARM cruise missile with a scramjet motor moving at mach 8 plus... and those balloons wont be looking up...

    Did American Missile Defense Fail in Saudi Arabia?

    Very interesting report from NY Times

    Did American Missile Defense Fail in Saudi Arabia?

    this goes against what Raytheon has been claiming so far

    Raytheon: Arab-operated Patriots intercepted over 100 tactical ballistic missiles since 2015

    Can America shoot down Russian and Chinese missiles?

    Is this true that America can shoot down Russian and Chinese Hypersonic Cruise Missiles?

    Hahahaha... in the article itself it mentions that speed is the problem and a faster interceptor is not really a solution... it makes things harder not easier.

    America can't shoot down hypersonic manouvering missiles... just like the Russians and Chinese can't either.

    A hypersonic falling item like a Scud or other ballistic target can be intercepted because its flight path is predictable... for an object flying at hypersonic speeds that is not ballistic and could go anywhere things are much much harder...

    Imagine an incoming Zircon missile moving at mach 8... which is 320m/s x 8 = about 2.5km/s...


    If you detect the target 100km away, you need to calculate its trajectory... its expected flight path... so with computers and three pings from the radar lets say that takes 4 seconds, so the missile is now 90km away, so you launch your missile to intercept and you vector that missile to hit the target... it will take your missile 25 seconds to get to the interception point because it needs to accelerate and climb... so that means the interception point will be at about 30km from your launch platform for the SAM... (the incoming Zircon will cover about 62km in the 25 seconds it takes your missile to get to the interception point... but hang on... unlike a ballistic missile... the Zircon can manouver in 3 dimensions... it can climb or descend and turn left or right... and it can speed up or slow down... in which case the interception point can change in a second and suddenly be several kilometres away from the original interception point.

    The problem is that any SAM launched it heading towards the old interception point and to now turn and head to an new interception point uses up energy... which slows it down... the target is still coming at 2.5km per second and that first missile might not make it to any interception point in time... it is not just a case of getting that interception missile to the same 3 dimensional point in space... it also has to be there at exactly the same time... half a second either way and you miss by over 1km... no amount of HE will be effective with such a miss distance.

    More importantly they will have programmed the missile to manouver to be difficult to hit... it is actively trying to avoid any missiles fired at it, though it has no way of actually detecting anything coming at it... unless they have made the radar antenna in its nose sensitive to ARH missile signals... it wont be able to track them but detection would warn the missile to manouver more... it is scramjet powered so it is still powered so manouvers wont reduce speed very much at all anyway.

    The Granit has titanium armour to protect the warhead from incoming Phalanx rounds... during testing it took two AA-9 missile hits to bring one down and it only moves at Mach 2...

    For intercepting missiles detonating the warhead is your best chance of defeating it... which is really hard if you can't hit it.
