In that case Maneuverability is not the correct word here, because maneuverability is defined as the ability to change the speed and flight direction of a missile. Obviously at hypersonic speed a cruise missile will not be able to carry out terminal manoeuvre.
Of course it will...
As far as interception of hyper sonic missiles is concerned the U.S has already created several prototypes of Directed Energy Weapons, some of which are entering limited production. For example the AN/SEQ-3 Laser Weapon System or XN-1 LaWS. In the interim, we have AD systems like the Oerlikon 35/1000 Revolver Gun, which fires the Advanced Hit Efficiency And Destruction (AHEAD) ammunition.
That is really cool, but what is their effective range and can they fire vertically?
Covering 3.2km per second in a vertical dive down onto a ship means one second before impact you have one second to destroy the incoming target that is initially 3.2km away vertically up and the next second is penetrating the deck of your ship.
The state of the art AHEAD projectile is programmed by a muzzle based electromagnetic inductor, which sets an electronic timer to activate and separate the projectile into 152 heavy tungsten metal spin-stabilized sub-projectiles (3.3 gram each), forming a lethal cone shaped metal cloud, placed ahead of the incoming hypersonic missile in its flight path.
How precise is the timer because if the target accelerates during its dive those rounds might detonate level with the incoming round which means short of a direct hit it will not effect the incoming missile.
Patriots in Desert Storm were not designed to intercept mach 7 targets, which is much slower so the fragments from the Patriot warhead explosions shattered the tail end of the Scuds but this was in the terminal phase of the attack when the rocket motors were not running any more... so these Patriots cut the rear of these missiles to ribbons but the warheads still fell on their targets and made huge holes in the ground...
Obviously, great and wise MBDA surely can make pop-up sea-skimming hypersonic missile.
Those are supposed to be supersonic missiles... will be a while before hypersonic comes in to the picture...
The funny part of that video is that there is a single shipping crate at a port with no air defence that opens and has cruise missiles which is immediately detected by satellite and there happens to be a ship offshore available to launch a missile to attack but no missiles to defend...
I get that. Therefore, I had mentioned that in the near future hyper sonic missiles will be engaged by DEW and as of now they will be engaged by electromagnetic rounds fired by AD systems like the Oerlikon 35/1000 Revolver Gun.
So if they can be engaged right now by 35mm cannon then why is hypersonic manouvering scramjet powered missiles seen as such a threat...
You do understand that even if your 35mm gun scores a direct hit on a vertically diving Zircon with half of its tungsten penetrators and completely obliterates its guidance radar the speed it is moving it will still hit the ship five times faster than any currently used rifle bullet and rip an enormous hole in the ship that few vessels could survive let alone continue to operate...
Another factor of course is... which western navies have 35mm guns on their ships at the moment... and can they fire 90 degrees straight up?
A swarm attack will also be confined to a small area. Moreover, you do realize how expensive it is to launch several swarm attacks with hypersonic weapons, don't you. Barring the US and China how many countries can afford that?
You don't need to bar the US, because they don't have any hypersonic anti ship weapons, and swarm could be two or three missiles at once because few systems can reliably intercept one missile let alone two or three.
Even a Gatling gun can rip open a hypersonic cruise missile
Hahahahahahahahahaha... who told you that?
Do you know that when the Soviets went to sea skimming supersonic missiles like Onyx the US Navy did proper tests on Phalanx and Goal Keeper... and then they started transitioning to SEARAM missiles instead of Phalanx or improved Phalanx with a larger calibre gun...
Gatling guns are fine for subsonic cruise missiles... which is why the AK-630, Duet, Kashtan and Kashtan-M and new Pantsir ranges still have them, but they also have missiles for faster targets... and to engage targets at greater ranges from the ships.
The tracking part will be taken care of by JSTAR and AWACS that are part of NATO's C4ISR architecture. They will pass on this information to the AD systems like Oerlikon 35/1000 which can then engage the hostile hypersonic missile.
They can hand off specific targets to specific air defence systems, but they can't provide target interception data in real time so the platform does not need a lock for itself...
