Could you explain why?
S-400 and S-300V4 are air defence missile systems that are fully mobile and able to pretty much defend a piece of airspace from pretty much any aerial threat.
That is from 4.8km/s speed incoming ballistic missiles, through to low flying cruise missiles and pretty much any flying craft in between
THAAD is designed to shoot down slightly improve SCUD missiles with a hit to kill missile that is not really suitable for anything else.
THAAD has better ABM characteristics than S-400 and S-300V4.
No it does not.
It intercept targets outside the atmosphere using kinetic warheads.
Why do you think that makes it better?
S-300 and S-400 still large explosive conventional warhed.
Which means it is much more versatile and able to deal with a much wider range of targets than THAAD is capable of.
THAAD is lighter and probably better maneuvering from the large missiles with S-400 and S-300V4.
Yet as systems the S-400 and S-300V4 are vastly more mobile and better able to operate in the field.... without dedicated satellite support...
Of course, the USA is developing much better SM-3.
But hang on, if THAAD and PAC-3 were both developed specifically to engage BMs and are so fucking wonderful at doing so why on earth would they waste money developing a naval version... and why did Japan choose it over THAAD?
Russia does not have the equivalent of SM-3 In the field of defense, ABM is far behind the USA.
Russia has had an operational ABM system around Moscow for the last almost 50 years.... most of what makes THAAD and PAC-3 Patriot came from what they learned from the S-300V system sold to them in the 1990s.
How any THAAD systems are operational and how many S-300V and S-400?
THAAD is intended to engage superSCUDs with speeds of mach 7 or more... S-400 can already engage targets moving at 4.8km/s...
that's why S-500 now enters production
THAAD was designed and built while the ABM treaty was in force... S-400 and S-500 after.
The Rim has a range of about 700KM, The Block 2A versions a range of like 2500KM.
AEGIS Ashore directly violates the INF treaty... as it can also take Tomahawk cruise missiles...
Both ballistic missiles types operate in the same manner and thus are both targets for the missile.
Like most ABM systems they are designed to intercept plain old vanilla BMs... missiles like Kinzhal and Iskander would be a real problem...
There is no point to argue. Both sides have different requirements and both are fallowing them. I dotn see any AMD sides having "better in all categories" missiles.
I do... PAC-3 and THAAD are rubbish... the only missile worth a damn is the SM-3 to be honest and it is still an anti IRBM system, whereas the S-500 is a full spec ABM system able to engage ICBMs and Satellites in low orbit... it would be interesting to see an air launched S-500 actually... I am sure they will be working on one.
In the mean time the ABM missiles from around Moscow are getting upgraded and improved too and made mobile if Nudol is to be believed... of course S-400 and S-500 and Nudol would have been illegal if the US hadn't withdrawn from the ABM treaty...
