    Glad you were not offended Lsos.

    I agree that in time they do need larger ships... small ships they can move through their inland canals that can carry long range land attack cruise missiles and bypass the INF treaty because the US insisted it not include air or sea based missiles, means they can attack most of NATO from rivers in Russia, but at the end of the day Russia needs to expand beyond its bases out into the world.

    Right now they have a lot of destroyer sized vessels and a couple of cruisers from the cold war that have plenty of potential in terms of upgrades with new weapons and sensors and systems... I personally think upgrading those will buy them 10 years where they can perfect their technologies in terms of conventional and nuclear propulsion and also their larger radar sets and bigger SAM systems that they will need to adapt to the naval environment.

    Producing smaller vessels means replacing older obsolete models with vessels comparable to cold war destroyers... a corvette armed with one UKSK launcher has the same main weapon fire power as a Sovremmeny class destroyer... in fact the 8 missiles it carries today outperform the Moskits the Sovs carried... Onyx with land attack capability is more flexible and much more powerful than the Moskit and it can also carry Klub and Calibr land attack missiles in the same tubes or even anti sub missiles... so in effect these corvettes can replace a sov class destroyer or a udaloy class destroyer with 8 91RE2s loaded in its UKSK tubes, and there was no Soviet vessel during the cold war that could carry 2,500km range land attack cruise missiles with a conventional warhead that could be used in conventional wars.

    Their new air launched cruise missiles have a range of 5,500km, so a naval model with increased range should not be impossible either.

    Upgrading existing vessels with UKSK launchers and new electronics and systems will greatly improve performance, while new build ships will have further advantages in even better propulsion and sensors and systems.

    The point is that it will take time and there is no super urgent hurry because right now they have a cruiser and they have destroyers that no one wants to mess with right now.

    The fact that they can't take on all of NATO right now is not important either... what do they actually have to fight them over right now anyway?

    Georgia?

    The Ukraine?

    They can have both.

    NATO bases in both countries would be very vulnerable to direct attack in any conflict... During WWII the Polish forces placed on the Polish border with Germany were obliterated quickly, as were French forces rushed to their border when their time came...

    Actually the main think limiting the speed of a missile is its motor... with a solid rocket booster a modern calibr cruise missile is relatively low drag but its engine is going to be relatively small so it is like a truck in that it will climb and build up speed after launch... its current top speed limited by the low power turbofan engine it uses for its long flight range.

    It would be interesting to replace that turbofan engine with high efficiency with a scramjet engine.... to solid rocket booster would get it up into the air and moving at a reasonable subsonic speed, and the scramjet could then accelerate the missile and climb to rather high altitudes where it could continue to climb and accelerate.

    As it burned fuel the missile would get lighter and lighter so higher speeds would become achievable... a small scramjet would not be able to make a big 2.5 ton missile supersonic at low altitudes but as it climbed and burned fuel and got lighter it is a long narrow low drag shape that for the first part of its flight it could be subsonic but accelerating and climbing and eventually accelerating beyond the speed of sound.

    A turbofan would not be able to allow the missile to be supersonic just like a boeing would not, but with a scramjet that is perfectly possible... the wings deploy to a straight position for early subsonic cruise and perhaps fold back as speed increases in a swept mode to allow the transition to supersonic speed... as it gets closer and closer to its target and burns off fuel and gets lighter and lighter and higher and higher it could keep accelerating all the way eventually getting to rather high speeds because there is no speed limit for a scramjet engine... there is no point where it stops generating thrust...

    A turbojet on the other hand will reach a limit where it will choke on the air because it is coming in at too high a speed at high flight speeds.

    Cool  Very Happy
    Different plate again Suspect

    Previous one

    and the one before


    Also pic from Balancer, must be 1st boat since it hasn't got the radar panels when this was taken

    That is because this time they've actually made a correct version of Pantsir's silhouette.

    Right you are.
    The older ones had it up on a pedestal for some reason.
