    The 0.8mach air vehicle will be more capable of evasive manoever than a more massive missile at higher endgame velocity. Is there a suggestion here that Vulan is at M2.5 in terminal phase?. I understood that, at very low altitude, these big missiles velocities were closer to M1.3-.5 than anything M2.silly or above?.

    That size is the price for speed, payload and range. Also, the Vulcan and Bazalt are not exactly new.

    Plus, it can fly fairly low if need be- 15-20 meters IIRC, which while not exactly modern sea skimming low, is (considering the speed) problematic for most defensive systems.

    Not quite that simple though is it TR1?. As an antiship missile this could only be for HVU targets and any modern ship target, worthy of engaging with Vulkan, is going to have the defensive screen able to counter it. Then there is that little question of targeting at x00km’s range. Uspekh is gone….Legenda is gone….Liana doesnt have its Pion ‘maritime recce’ component launch-ready yet as I understand it?. Whats left that can talk to Vulkan for MCG?. Ka-31/Oko?.

    http://thediplomat.com/2015/07/revealed-details-of-indias-second-indigenous-aircraft-carrier/

    The Navy’s letter of request states that that carrier will be the first in the Indian fleet—and first non-Western carrier—to field a catapult launched but arrest landing (CATOBAR) aircraft launch system.

    First for CATOBAR in the Indian fleet???. I think not!. Bad, sloppy, journalist….for shame sir! 🙂

    My view is that this is still telling

    “Interviewed in January 2014, Air Vice-Marshal Philip Osborn, Director of Capability, Joint Forces Command stated that the UK had “every intention of continuing to utilise Reaper beyond Afghanistan”. He continued:

    You will see us plan to bring Reaper more into an expeditionary, rather than deployed mode, and over the next few years we will shift from Reaper into the Scavenger programme, [which] should be capable of doing far more, on a worldwide basis.

    The buzzwords are there to map to Carrier Strike. What we will see dedicated to Carrier Strike in the nearer term is more nebulous….we’ll see when the footage from next years Joint Warrior comes out!.

    Fresh detail of how Scorpion operated in conjunction with RN Seaking 7s in recent trials off the South Coast:

    http://www.flightglobal.com/news/articles/riat-scorpion-proves-maritime-surveillance-fit-during-uk-414841/

    From the article:

    “During a series of around eight flights, the Scorpion was tasked with inspecting maritime surface contacts by observers aboard a Westland Sea King 7 airborne surveillance and control helicopter from 849 NAS, based at Culdrose in Cornwall.

    “Royal Navy crews were able to use the Scorpion for valuable controller experience, while Textron was able to put the recently integrated Thales I-Master radar through its paces in a maritime environment,” the US company says. The aircraft’s L-3 Wescam MX-15 electro-optical/infrared sensor was also employed during the activity.”

    Sounds more like it was simulating UAV operations than anything specifc to do with the aircraft. Textron got a free chance to validate the little Thales set and get a bit of advertising done at the same time plus a spot of training for the 849 bagmen. Merit all round…but, as thought, nothing that looks like genuine interest in the Scorpion.

    ^ I was alluding to that thanks for bring it up
    Is there a place where I can read more details on the SOviet air-sea battle tactics in the late cold war era ?
    I mean how they intended to guard their SSBN
    Deploy their DD/FF to counter western Aircraft carriers and other surface fleet
    And their ASW doctrine
    etc

    That pic was solely meant to ‘drive home’ the point about “Clearly mad putting all that superstructure sail-area that high up in the design….any serious wind over the beam will make that an entertaining hull to crew!”…. I couldn’t find any better pic of T45 that highlighted this design aspect of the mast w.r.t to the hull and bridge so well.

    Not sure I’m really seeing your point Jang?. The T45 doesnt have a huge sail area aloft….the mast, compared the the bonkers ‘destroyer’ (28m in the beam you reckon…..destroyer!???) the T45’s radar mast is extremely modest and uniformly narrowing throughout the transit aloft. The picture you showed had her heeling over but not through any cause of winded area?.

    If you really want to consider the mast height, consider it from the top of the main bridge and you might probably understand that it is probably of the same height as we see on Pr.1144 and even in comparable ratio or maybe even of same height as that of the T45.

    Do you want, perhaps, to look at that again Jang?. In both cases, Kirov and Bonkers, the bridge looks like it sits roughly at 04 Deck level. To the top of the superstructure in Kirov is to go to the bottom of the volume search array pedestal. For Bonkers you’re still placing winded superstructure area above the height that would be lattice antenna on Kirov…that seems very clear to me from your images?.

    You can do a simple ratio of keel to bridge height and from bridge to mast height, it wont be much different. Btw, don’t forget that this is a larger ship than T45 in both size and tonnage.

    Perhaps so but there is no comparison in sail area…you cant say that Bonkers will be fine just because its mast to beam ratio may be similar to that of T45?!. The winded area at that height is the most important factor.

    Dont worry, it is and the beam is much more than 20m, the spec mentioned in that brochure is 100% wrong if the model displayed is to be considered. Don’t be surprised if the max beam is 28 meters like that of pr.1144.

    Unless the brochure is right and the model wrong?!!. Again a DDG with a 28m beam and, off that, about 20,000 tons of displacement is bonkers by itself….without the additional design ‘eccentricities’!. I know you would like to find merit in this Jang, on some level I guess it is ‘cool’, but I dont think theres much to be said in its favour to be honest.

    Exactly
    I mean the Kresta II, Kara , udaloy are very weak in this anti-ship department and defenceless against Harpoon armed ships even of the japanease navy.What was the plan of the soviets to protect these ships from such harpoon armed ships ?

    As noted above these class of ships were ASW hunters. In Gorshkovs doctrine they would be forward deployed as part of a taskgroup to prevent NATO/opposing forces from interfering with friendly submarine taskings in blue-water. The group, in the early 70’s era onwards, would have comprised heavy missile ships like the Pr.58/Kynda’s or -1 Kresta’s with P-35’s etc to engage hostile surface units at extended range. Added to that would be the heavy missile fire from a likely taskgroup flag like a Kirov or Kiev class.

    I think the torpedoes could target surface targets – not 100% sure, though. I believe most naval SAMs have surface attack mode, though I have not seen this explicitly confirmed for SA-N-3 (Shtorm).
    And of course, there are guns. Though Krestas are weak in this department.

    The Kara’s are commonly quoted as being equipped to fire the 53-65K 21″ wake-homers and so had an anti-surface capability in that regard. Best you’d get, against a 30knt combatant target, though would be a solution at about 8-10,000yrds range max….same sort of range as, allegedly, the AK-726s were effective at for surface fire. Getting close enough to employ either would, you’d assume, mean something had gone quite badly wrong somewhere!.

    http://4.bp.blogspot.com/-6CsMupopUB4/U_gCoTszf9I/AAAAAAAAJYQ/8-9xSPS7shQ/s1600/Royal%2BNavy%2BType%2B45%2BDaring%2Bclass%2BDestroyer%2B1.jpg

    Think you’ll find that is a max speed turn Jang but it is a good illustration of what happens when one has a broad sail area in a strong beam wind!. The contrast between the ‘Bonkers’ destroyer and the Kirov is actually quite well marked out in the photo you’ve selected there. Look at the bridge height in relation to the top of mast. Its a LOT higher up with the pagoda than it is even with the hefty installation on Kirov. Also look at the winded area of the top ‘pyramid’ compared to the equivalent area on the T45. In both cases you’ll see that the ‘fantasy fleet’ Russian design is much higher and wider than the comparable designs.

    The beam reported is 20m which I think is on the lower side. To me the beam is definitely over 20m and probably around 24m?

    Its to be hoped so and more….T45’s max. beam is 21m and its a much smaller ship than this!.

    Jinan,

    Having said that (and making sense imho), how do you view/read the carrier model put forward by the Krylov Institute?

    To be honest I looked at it and lost interest when I saw the mini ‘ski-bump’ on the end of the deck-angle. Bad news news if you miss a wire on this ship it would seem…higher landing speeds needed to get you up and over the bump above stall speed I’d guess…certainly I’d expect it to make bringback weight calculation messy!?. I actually first thought it was some kind of posh fan-art as opposed to something from a real design house?. From TR1’s above comment though perhaps this is just a case of posh fan-art from a real design house! 🙂

    Again an issue would crop up of doctrine….explained again by TR1 as it appears not to have been conceived to fit in to any specific doctrine!. To explain what I mean…..if I say that, until you put the context of UK Carrier Strike on to CVF, it is indeed mind-boggling getting your head around the idea of a modest-supercarrier-sized STOVL flat-top!. Translating that to this ship I cant actually conceive of the doctrine that is best serviced by a rough 90k ton STOBAR aircraft carrier.

    From the sheer size and aircraft arranged on deck it looks like a CVN in the USN model….both of which together implies a requirement for a specific sortie generation rate. Then, though, you look at the images from dead astern and you see all deck launch spots, bar one short spot forward at roughly centreline, foul the landing strip…bump and all!. So you have a multirole strike/air supremacy airgroup in the conventional model but an inherently slow launching platform and no support refueller type….therefore a requirement to always utilise some percentage of your group buddy-stored to keep the first strikers launched topped off. This when shorter launch cycle time provision from CATOBAR has to be a viable option technologically and validates the size and airgroup. It all looks a bit confused to me but…like I said thats based only on a cursory glance at the photos and a suspicion that the person doing the design knew more about ships than actual operations!?.

    Destroyer? That thing looks more like the size of a Kirov, there are other models with an extended flight deck big enough for 5 or 6 helos.

    Was thinking the same….cant wait to see what they come up with as a cruiser concept!. Clearly mad putting all that superstructure sail-area that high up in the design….any serious wind over the beam will make that an entertaining hull to crew!.

    The other thing thats interesting, if this is an officially sanctioned design and not just some naval architects unsolicited occupational meanderings, is what it suggests in terms of Russian operational planning. You build in a tail foremast for one reason and one only…to push back the horizon for your sensors. If you are planning to operate under friendly airborne radar coverage thats not so important….see current and projected US designs. Given the years of repeated noise about Russian carrier ambitions, and models with E-2 clones parked liberally about the deck, this design is more indicative of a unit intended to operate with a far lesser reliance on that offboard support.

    Lets take her for a spin 😉

    I’m old school I’m afraid!. Give me an 1135M for the joyride 🙂

    I am impressed, at face value, by the earlier imaged Saphir though. Be very interested if anyone knows unit costs and operational design criteria for the hull (mission capable seastate limits etc)…also the 20 man crew looks good for a hull with a 30 day endurance…does anyone know how this works in the Border Guard?. Is it a CO, XO and three 6-man watches or a generally less structured operational pattern?. Curious to know how lean the ship can be run?.

    OK I think this has diverted enough from the general point I was aiming at so I’ll make the following points and leave it at that:

    • Hanit was hit by a C-701 or copy thereof…not an 802.
    • I’ve suggested all the way through a platform that can be deck or shore based. Your solution studiously avoids the carrier.
    • MPA buy suggested in the media, as mentioned, is token not a genuine MPA capability. See Japan for the real deal.
    • ASAC7/Baggie-Merlin is not an attrition-tolerant platform. Neither is Sentry, Sentinel or any flavour of manned MPA.
    • Without persistent ISTAR maximum return from the Carrier Strike investment cannot be achieved. F-35B is also not an attrition-tolerant platform!.
    • Evolving ESTOL technologies, already funded to concept, offer STOVL deck-capable support airframe opportunities that havent existed before.

    Where else would they rather be? And so could coverage with multiple ASACs.

    Presumably being part of the UK air defence environment. How many Sentries do we have again?. I claim no air operations expertise but we do need to sustain coverage of UK airspace even while we embark in combat operations elsewhere?. I’m not sure its so essential that we have a few SSNs in home waters at all times provided we maintain FRE etc.

    Matter of opinion. Hanit was hit by one missile. Stark – only one missile exploded, both hit at same point.

    Neither ship stayed in the fight after their missile hits. Hanit was hit by a basic lightweight AShM.

    Right so one E-3 flying at 600mph can’t cover the airspace even with several ASACs and MPAs flying combined ISTAR but 7 submarines travelling at 30kts can cover the subsurface?

    I didnt say that an E-3 couldnt get to the Falklands. I said its unrealistic to think we’d send a detachment of enough aircraft to maintain round the clock coverage.

    It’s not like UAVs don’t require support equipment and traning and the above items don’t crash as often as UAVs. How much does that cost, even if they don’t crash into the carrier itself? 10.2 losses per 100,000 flying hours. That’s $200+m even without the radar.

    Its also 100,000 flying hours using your numbers!!!!. By my rough mental calculation thats more than 10 UAVs flying 24hrs every day…consecutively for a whole year. Coverage that, to replicate with Sentry, would mean perhaps 2 airframes aloft permanently so a, rough, squadron strength deployment?. Doubling the E-3 force plus all of the routine operational costs would come with a significant price tag you’d expect….plus it’d not be such a useful platform for ISTAR would it….remember the UAV can do both. I’d imagine replacing 10 UAV’s per 100,000 flight hours would be the infinitely preferable option!.

    So you want to see ships from a long way off but not actually have the ability to hit them with anything useful?

    Nope I want to have positive ID on the ship target before I fire a missile at it and need to be sure that my weapon isnt going to veer off and sink a ferry load of nuns, orphans and CNN reporters by accident. That is why we have RoE’s after all.
