    hope this program could have a happy ending.

    I’ve been reading about them being upgraded/repaired since 2004. I’m not holding by breath for any such ending before 2020, if even then.

    Redut has longer range than 9M100, right?

    IMHO even this is a bit much for a corvette. 16-24 upgraded Kinzhal would have sufficed.

    Detection range of fighter 30-75 km, detection range of AShM 10-14 km.

    To add on to that, the figures are for a 1m2 target, the range is for “trajectory detection”. What is the “Dezhurny Regim”? The figures are doubled for fighter detection.

    Number of targets tracked, from 50-100-200 depending on variant.

    Thank you both very much.:)

    My other question; what are the black squares on the exhaust of the Stereguschy upgrades in Austin’s pics?

    Excellent find, Austin!

    Those are some great-looking ships. Not as stealthy as a Visby, perhaps, but they have the capability of a frigate with a corvette’s displacement.

    Are the black squares a new heat-suppression system for the exhaust?

    I have just one thing to add: A few scans from a Russian article on the Furke-E radar.

    A fixed 4-planar array version?

    A spec sheet. Would love it if snake65 or somebody else translated it a little; for instance what’s the detection range for a fighter?:)

    Regarding the Mistral, why does it, along with every other LHD in its class, only have a top speed of around 18-22 knots? And why do all of them except the LPX Dokdo have electric propulsion with azimuth thrusters?

    Agreed, but all the other warships on the export market are frigates in the 4000-6000 ton category. I find it curious that aside from the Chinese Sovremennys there has not been a destroyer purchase in recent naval history.

    Certainly is or was! They tried to sell eight and nine to Saudi Arabia who didn’t bite. They then pulled the plug on it and settled on six.

    I get a vibe that if the Saudis had gone for a couple of Type 45 the UK might well of got two extra themselves after satisfying the export order.

    How much would an export variant have cost?

    Sorry for reviving this old thread, but I have a question which I think best belongs here. Is the Daring class allowed for export, and if it is are systems like the SAMPSON radar and PAAMS exportable?

    Also who said the Vik is using the same propulsion as the Kuznetsov? The Kuz’s propulsion has been problematic for years, is going to be completely replaced during its refit. I find it extremely unlikely the Vik will repeat the mistake.

    The Kuznetsov inherits its propulsion system from the Kiev class: 8 KVG high-pressure boilers, 4 steam turbines, 4 shafts. It has always been troublesome even in the Kievs and every ship in the class has had at least one major boiler fire. The Vikramaditya only differs by having its boilers refurbished and converted to use diesel instead of fuel oil.

    Nerpa will be handed over to India before October.
    Lease is for ten years, cost – 920 million dollars.

    Seems high for a mere lease agreement. How much does a new Akula-II cost to build?

    where did you get that figure from? I could not find it.

    Btw, my info suggests the deal was very comprehensive (including the warranty related) and the contract(sub-contract, sub-sub contracts, etc) signed during 2004 runs over 10,000 pages. Probably only JM reported on that aspect.

    The figure was from an old Sevmash newsletter I believe. I read it on these forums years ago.

    I’d love to see your info regarding the deal.:) Can you give me a link or attachment?

    Its little hard to understand. But it mentions the problem of Kuzentzov in the chilly conditions of the north.

    Where is the problems related to Vikramaditya?

    Vikramaditya uses essentially the same propulsion system, and its ventilation system is even less equipped for cold weather(being designed for tropical conditions) than Kuznetsov. So there may be problems.

    Russian submarines have carried MANPADS in the main mast since thr 80s. But they have to surface in order to fire them, with the obvious disadvantage.

    In order to fire a SAM without surfacing it has to be an underwater-launched missile. The only such system in development is the German IDAS.

    Future russian “fifth generation” submarine will use both ballistic and cruise missiles:

    http://rian.ru/defense_safety/20110319/355549208.html

    So the Navy is going for a “unified” hull in the future? What’s the advantage, costs?

    Interesting. Given that structurally, SSNs and SSBNs are identical aside from the VLS cells in the latter I always wondered why their operators had to maintain two separate design and production lines for them. Why not just put VLS cells for ballistic missiles on an existing SSN design? I understand SSBNs need to be larger in order to accomodate enough missiles, but what other specific differences are there?

    -Isn’t the S-300V3 the Antey-2500 that was once offered for export?
    -Is a tracked version of the S-400 under consideration to replace the army’s S-300V batteries?

    A question for those who may no something about submarine propulsion: would a dual-reactor, dual-shaft configuration like in the Soviet Victor class be noiser than a comparable single-reactor-and-shaft propulsion system?

    Interesting report…

    Russia is developing a new type of submarine with a “closed cycle” engine. It will also have a supplementary diesel engine and be able to operate underwater for a period of several weeks without the need to surface.

    It’s intended for coastal water operations

    Russian Source:
    http://flotprom.ru/news/index.php?ELEMENT_ID=65499

    I don’t follow naval developments very closely so was wondering if this “closed cycle” engine is a Air-independent propulsion (AIP) system or something else?

    Sounds like something similar to the MESMA. This may be incorporated into future Ladas or Amur class submarines.

    What about the Kristall-27 AIP system, then?
