    Mixing and matching theater systems with homeland defense ones does not a layered defense make! THAAD is practically useless for the homeland defense mission (intercept). Terminal defense against ICBM went away with Sprint so only option there will be GBI which is a mid-course defense system. AEGIS and SM3 is also not going to be plucking ICBMs launched from Russia towards the US, either out of the two Ashore sites or off of a ship. Those that have done the math behind the engagement trajectories and the intercept dynamics have found the system to be of no practical use in this role. So to be clear, AEGIS and THAAD do provide layered capability but that capability is for theater defense, not the homeland defense mission. As far as that area is concerned, there is only the Mid Course defense capability currently deployed or in the works, which given its upgrade path, is reasonably sufficient (or as adequate as one could be for a missile defense system which is only one part of the national defense capability to deter or prevent strike) for the types of threats it has been designed to overcome.

    On paper yes, but I bet THAAD and SM-3 would have some success against ICBM warheads.

    GBI has a capability against rudimentary ICBM. Each carries one EKV and intercept would occur after warhead and decoy deployment. Against an ICBM with multiple MIRV and decoys, the GBI is of limited value.

    The entire planned fleet of 44 interceptors wouldn’t guarantee a defense against 10 MIRV equipped ICBM’s (even accepting the B.S. oft quoted 97% success rate).

    Depends where the GBI is based and when the ICBM’s warhead bus releases the warheads. What has Russia/China got that can intercept mid-course though? Okay, it’s not full-proof but when you consider GBI, SM-3 IIA, SM-3 1B and THAAD, that’s at least a decent multi-phase, layered intercept system, which surely beats 56 short-range (80-100km), nuclear-tipped 1980s interceptors hanging out around Moscow only.

    How many tests has the S-300/S-400 performed against MRBMs/IRBMs and how many have been successful? We hear about maximum target speeds but where is the actual test evidence? SM-3 IA on the other hand actually hit a falling satellite doing 9.8km/s, which is well beyond its design specification and then you have successful IRBM intercepts by THAAD and ICBM intercepts by GBI.

    Then the US can expect a new arms race, with new, destabilizing non ICBM delivery vehicles to actually be developed and deployed full force. And it won’t be just Russia who reacts badly to such a imbalanced development.

    The nuclear torpedo and cruise missiles are messages that Russia does not like the implications to its ICBM counter-strike capability, and your response is to ACTUALLY work against that capability? In other words, justify every fear that Putin talked about.

    Insane.

    Given the current proliferation of nuclear weapons, including ICBMs to the likes of North Korea, the only future is to neutralise the effectiveness of all nuke delivery platforms.

    I wonder whether recent developments will see a return of SDI in its full, original, intended anger. Given developments over the last 20 years, I bet there are many who wish it’d never been dropped.

    Worst case scenario, the UK has access to all the intellectual property and would manufacturer the fuselage in the UK.

    That was not my conclusion at all and is most definitely not what I was saying. I pointed to the misrepresentation of Intercept test data and was trying to point out that if one were to analyze that and use it as a measure of the defensive capability of a Carrier Strike Group (it is not the best way to look at this at all since missile testing usually focuses on intercept or sensor preformance, not the entire spectrum of offensive and defensive capability a strike group will show up with) then one must also weigh this against equally detailed data from the missile testing and evaluation. It is rather pointless to say that 2 of 10 missiles,(or 4 of 10 or 10 of 10) will get past a particular interceptor unless we know the other variable in this equation i.e. how many of the offensive weapon will actually find, fix and succesfully strike a defended target at sea. Any long range ballistic missile has to first network with long range sensors, and command & control, evade exoatmospheric and endoatmospheric interceptors, succesfully operate in a cluttered environment where Electronic Warfare capabilities are being used against its seeker and navigation concepts, find its target, verify that it is the correct target, and then finally strike that target. If one is going to analyze the abilities of the interceptors to succesfully engage a MR or IR Ballistic Missile in space or inside the atmosphere, then it is also reasonable to present similar performance and flight test data on the performance and test data from the offensive system in question as well.

    Fair point. You have EW spoofing targeting before then, Pk of the actual attack missiles, EW spoofing the terminal guidance, the launch jet being shot down, or having its runway bombed out, before you even get to terminal phase intercepts.

    I think the most ideal system presented was Avangard, which has been confirmed ordered.

    I was under the impression that would be a nuclear-only glide warhead.

    In one of the interview I posed from Tactical Missile Bureau , He mentioned that Kh-101 can fly accurately to the target even without Glonass or GPS , its designed to do so with a highly accurate INS and other aided navigation built in , Considering Kinzal flight time is likely 1/10 of that Kh-101 and the accuracy would be quite good as its aided by RF seeker and even Optical one

    In the end it depends on the type of INS you use and how much one would like to spend on it a strap down INS would be less accurate compared to Laser INS but from a mass deployed weapon strap down INS would be cost effective choice.

    Cruise missiles generally use TERCOM as well as GPS/INS but TERCOM wouldn’t work particularly well over the sea.

    Laser ins are used even on icbm they are very precise due to short duration flight the error accumulated is low

    INS is backed up by astrological referencing with ICBMs. It’s possible the Kinzhal would use something similar, since it must fly a mostly ballistic path to attain 2,000km based on Kh-32 size and range.

    I agree with the above. You would probably need about 20 Kinzhals to land one hit.

    Any word on what guidance the Kinzhal uses?

    About 2 per Yankee carrier is being generous

    Don’t bet on it. A Nimitz class can take 3 heavyweight torpedos in separate compartments, aside from being guarded by a large number of guided missile destroyers with missiles capable of shooting down the Kinzal.

    I’m pretty sure that one way or another Germany isn’t going to get in the way of this deal securing jobs in UK.

    I believe the work share only pertained to partner nation planes. Italy was selected to build the Kuwaiti planes and Britain is selected to build the Saudi ones.

    what if Germany halts components to this deal considering its negative impact on them.

    Then they get built elsewhere, I would assume.

    Did they actually deliver the full 72 in the first lot, I thought they stopped at 48?

    Spitfire, I don’t think the first 48 were Tranche 3, so no. This 48 almost certainly will come with AESA included though.
