    It is interesting that the Project 15A destroyer still has a Thales LW-08 radar – not really the newest generation of radar.

    Thales LW-08 D-band air search radar+
    IAI EL/M-2238 L-band STAR surveillance radar+
    IAI EL/M-2248 MF-STAR AESA multi-function radar

    Thales LW-08 Specifications
    frequency: D-Band
    pulse repetition time (PRT):
    pulse repetition frequency (PRF): 500 or 1000 hertzes
    pulsewidth (τ):
    receive time:
    dead time:
    peak power: 150 kilowatts
    average power: 5 kilowatts
    displayed range: 140 nautical miles
    range resolution: 0.5 nautical miles
    beamwidth: 2.2 degrees
    hits per scan: 15 to 20
    antenna rotation: 7.5 or 15 rpm.

    The JUPITER/LW 08 2D-early warning radar performs long range (260 km on 2 m² RCS target) air surveillance on board medium and heavy-tonnage ships. The radar has a high performance in an electronic countermeasures polluted environment: excellent clutter suppression. Employed e.g. on F123 Brandenburg, Doorman M-Frigate, Heemskerck class L-frigate.

    EL/M-2238 L-band STAR
    STAR is an acronym of Surveillance & Threat Alert Radar, a multi-purpose air and surface-search naval radar system. 3D multi-beam and multi-mode fully coherent pulse Doppler search radar which functions in the S band . It comes in three variants – a larger dual-face version, a medium version and a small single-face version
    200-350km instrumented range
    150-250 km against aircraft
    20-28km against missiles

    EL/M-2248 MF Star
    multi-function solid-state active conformal phased array radar system. The MF-STAR antenna includes 4 faces of active array in S-band frequency. MF-STAR employs multi-beam and pulse Doppler techniques as-well-as robust ECCM techniques to extract fast, low RCS targets from complex clutter and jamming environments.
    Against missile 25km
    Against aircraft 250km

    India may acquire upto 15 Shin Meiwa US-2 amphibians..may well be the first Japanese defence deal with India.

    India to acquire 15 US-2i aircraft from Japan after defence minister’s visit

    Count on more than 15…

    India’s plan to acquire at least 15 US-2i amphibious aircraft for its Navy from Japan is expected to fructify when the defence minister of Japan arrives in India next month.

    Interesting …

    India has accepted the high cost of the aircraft to build up the strategic partnership.

    To keep in mind, the precursor:

    The PS-1 ASW variant carried homing torpedoes, depth charges and 127mm rockets as offensive armament but had no defensive weapons. It was equipped with dipping sonar, which had limited use as it required the aircraft to land on water to deploy. It could also carry up to 20 sonobuoys.

    The PS-1 had not been in service long before the JMSDF requested the development of a search-and-rescue variant. The deletion of the PS-1’s military equipment allowed for greater fuel capacity, workable landing gear, and rescue equipment. The new variant, the US-1A, could also quickly be converted for troop-carrying duties.

    Still needs an extra logistical chain. What advantage does it offer over CAMM, which will be in inventory anyway, to justify that?

    Agree. Advantage of SeaRAM is possibility to recycling parts of any Phalanx unit, it has a very small footprint and same consoles as Phalanx (training advantages?).

    I’ve seen various places saying different things, but the most consistent I’ve seen was about 50 aircraft 24 fixed wing, 26 rotary. That wikipedia link is definitely the lowest I’ve seen — but I think that’s reflective of just how many Su-33s the Russian Navy has in working order rather than capacity.

    The wiki may wel be correct. Much depends on what aircraft type was counted (relative footprints and volumes required)

    Technical proposal for a heavy aircraft carrier, etc. 1143.5 was developed by April 1978 when you save a sufficiently high degree of continuity with TAKR Project 1143.4, the new ship was supposed to use the new avionics, antiship and antiaircraft missile weapons, destined for the big cruisers of project 1153. Significantly change had flight deck, where there were air-technical means to take off and landing aircraft ordinary scheme – catapults and arrester. For boiler-turbine installation project TAKR 1143.5 corresponded to ships under construction project 1143.4.
    The maximum size of the air group on the draft of the new cruiser was 42 naval aircraft (LAC), including 18-28 aircraft and 14 helicopters. At the same time provides the following configuration options for its aircraft: 28 Yak-41, 18 Su-27K, 28 MiG-29K, 16 Yak-41 and 12 MiG-29K.

    http://paralay.net/atakr.html
    18-28 + 14 = 32-42

    From FAS

    The ship has the capacity to support 16 Yakovlev Yak-41M (Freestyle) and 12 Sukhoi Su-27K (Flanker) fixed wing aircraft and a range of helicopters including four Kamov Ka-27-LD (Helix), 18 Kamov Ka-27 PLO, and two Ka-27-S.

    http://www.fas.org/man/dod-101/sys/ship/row/rus/1143_5.htm
    28+24 = 52

    Compared to wiki
    14 + 17 = 31 (with su 33)
    28 + 17 = 45 (with Mig29K)

    To address a detail regarding Liaoning (and also Vikramditya by extension): sortie rate and force projection. Both ships are STOBAR as we’re all aware, and both can field a decent number of planes. Liaoning can carry 24 J-15s along with 26ish helicopters, I believe Vikramditya can hold 24 Mig-29Ks and some 6 helicopters, based on that diagram of hangar/deck dispositions. Either way, 24 J-15s or Mig-29Ks is a potent airwing, and is relatively comparable to the CdG’s airwing of Rafales (which I’m sure we can all agree is a potent blue water power projection vessel!). With competent crews, there’s no reason why Liaoning or Vikram cannot do competitive sortie rates considering the size of their airwings.

    Recall Kuznetsov: http://en.wikipedia.org/wiki/Russian_aircraft_carrier_Admiral_Kuznetsov

    Fixed Wing; 14 × Su-33 fighters (current) or 28 × MiG-29K fighters (planned after refit)
    Rotary Wing; 17 x
    4 × Kamov Ka-27LD32 helicopters
    11 × Kamov Ka-27PLO helicopters
    2 × Kamov Ka-27S helicopters

    That is 14 jets (maybe 18 if you throw in some SU25 for training) + 17 heli’s . A far cry from 24 plus 26
    I doubt Liaoning is magically capable of carrying much more than Kuz….

    From CDF: captain Liaoning recently stated aircraft total on board is 36, which suggest 24 jets and 8 ASW heli’s and 4 AEW heli’s. http://www.china-defense.com/smf/index.php?topic=6582.msg224794#msg224794

    Probably. I can’t see what SeaRAM would add that would justify an extra logistical chain.

    RAM block 2 will be available in VL.

    Thales Cerberus suite is meant to be extremely good. Going by BR stats the E-801M on the Kamov is good for holding 40 simultaneous tracks…I know that Cerberus can do several multiples of that. In reality though, apart from finding alternate uses like the overland ISTAR ASaC7 has been pressed into, I’d imagine any differences would be pretty much academic in the aircrafts primary tasking.

    You do seem very willing to overlook a 300% cost increase and 52 month original delivery schedule missed by about 4yrs for Gorshkov though.

    I have not seen any rumours about India considering project 22356. Maybe later but I doubt that India would be interested in buying project 22356 until the next talwar batch have been delivered. Assuming the talwar deal will happen. I am also pretty sure Russia would have some serious problems to build 22356s for India in a time schedule which would satisfied India.

    Perhaps not, if the export versions doesn’t has all the newest gear and is made entirely of steel ?

    I have not seen recent pics but here is one which I saw a while back. It is not a great pic but I have been told that taking these kind of pics in Indian shipyards is a big NO-NO.

    15A… goodie! ‘t will be interesting to see better pics of these when they become available.

    Wan,

    Point well made. I did read something, a couple of years back to the effect that the Yak-44 was being resurrected…or at least looked at good and hard…as a precursor to a re-engagement with carrier building in Russia. I always thought that this programme would be a good litmus test of where the Russian Navy was at with the whole thing. I’ve heard nothing new regarding that aircraft design for at least a year and a half…you picked up anything more recent?.

    Agreed, but, that owes little to the actual design of the Russian ship…propulsion, crewing, major subsystems etc all very different. Nothing of the Kiev class heritage has pulled though

    Yeah, but I don’t suppose logistics are the key issue here.

    Absolutely not. I’ve never intended to give the impression that the ship is useless. My point is that its simply little more use than the Viraat in strategic terms.

    I doubt it was ever intended as more than stop-gap. But we’ll see. She may be around for some time, as you indicated 😉
