    I’m usually okay with getting things from Wikipedia, but when it’s unconfirmed things that have a track record of being more ideas than serial components, I’d like some other sources.

    I think the designation I’ve heard for the tail radar in both the Su-34 and 35 is N012.

    Any truth to this? And is it on the serial aircraft?

    Good wiki’s will have a whole list of open source references at the bottom. It should be fairly straightforward to assess the accuracy of a wiki on that basis. Just as one would to to assess and article in a professional journal. In that sense, it is folly to dismiss wiki outright.

    In the Su-34, the front-mounted radar is supplemented by a rear-aspect V005 radar housed in the long tail “stinger”.
    http://en.wikipedia.org/wiki/Su-34#Cockpit_and_avionics

    The modernized Su-35 was presented at the MAKS-2007 air show in August 2007. The new features of the aircraft include a reinforced airframe with a more extensive use of titanium alloys, thus increasing the airframes durability to some 30 years or 6,000 service hours,[19] a reduced radar signature from the front,[16] and an improved passive electronically scanned array radar. The aircraft featured many other upgrades to its avionics and electronic systems, including digital fly-by-wire and a rear-looking radar for firing Semi-Active Radar missiles

    But wait! Not everyone has fancy radars and IR sensors. Those enemies still rely on mk1 eyeballs. Keeping airplanes painted in camouflage colors still provides a benefit in some combat situations.

    Metamaterials…

    I don’t think Vietnamese navy ever order that :confused: Myanmar is the ally of China and it’s supporting bilateral talks to solve dispute in the South China Sea. The political instability of Myanmar is a big turn off for any purchase decision from the Vietnam side no matter how good their weapons are.

    It did sound a bit odd, plus I found different ship characteristics and no pics, making the whole thing a bit iffy imho.

    but where was Russia (or SU I should say) when China invaded Vietnam in the late 70s despite a defence agreement?

    Too busy trying to keep up with the Joneses (USA) in order to risk a second antagonist on another border? Besides, why whould they interfere in a dispute between communist brother nations?
    😉

    These two boats are a start, but Vietnam’s going to need something larger and more powerful if it hopes to defend its maritime claims against China.. and to some extent, Malaysia and Indonesia.

    Like six Russian-built Kilo-class attack submarines maybe?

    THese ships are a big step up from the Petya’s. But didn’t the Vietnamese navy acquier a (yet larger) frigate from Myanmar (Aung Zeya class)

    Well yes , the main ASW operations of this ship has to come from the Seakings with torpedos and close in measures from the RBUs which the IN are very fond of.Its unclear whether the seakings still carry the sea eagle.Most probably not.upgraded seakings or replacements will be fitted with new ashms.At present there are multiple Ashms in/going to be in service from kh 35s, harpoons and exocets.So any of the above could be fitted.
    As for fitting the VL cells , it has to depend on the type of mission and the sub surface threat in that scenario.In any case , ASW warfare is not the main role for this ship mainly self defence is needed.For that I think the helicopters and the RBUs will suffice.

    If they are intended as fleet escorts (i.e. carrier screen members), they had d*** well better have very decent ASW and AShW capability in addition to good self defence AAW and a the ability to provide some consort ship protection! Given 2 Sea King, ASW is very much to be their role, I think!

    None of the helilaunched missiles mentioned (Sea Eagle, Harpoon, Exocet, Uran) offer the supersonic terminal stage that the 300km 3M-54E – anti-shipping variant offers …

    I heard that the main task of this vessel is as a command post (Sigma-E) system so it has good radars and datalink system to provide intels and guidance for smaller ships that Vietnamese navy is having in its arsenal. As a result, the ability to carry helicopter is not particularly important.

    Important enough to give her a landing pad. Likely she can also rearm and refuel a helicopter (otherwise just the pad itself would have sufficed). The extra step to include some form of (bad) weather cover is minimal imho and makes her more verstile.

    Excellent article on P 17 frigates.

    http://www.scribd.com/doc/56991175/In-Indian-Navy-s-P17-Stealth-Frigate

    The remarks concerning the omission of (ASW) torpedo tubes seem a bit odd imho. At range, this (ASW) is mainly the job of the 2 helicopters and it seems unwise to sacrifice any of the limited number of VL cells to carry the 91RE2 missile for that purpose (leaving how many slots for the AShM variant of 3M-54 Klub family? Although that argument can be countered by pointing out that IN SH-3 Sea Kings could be used to carry and launch the 110km Sea Eagle AShM.). The role of the RBU-6000’s may be close in ASW but they may well double as a torpedo defence and diver protection (if they are RPK-8 variant)

    1 more of the Vietnamese Gepard

    Thanks for this view. Looking at it, and particularly the service-bay-like area just forward of the landing pad, I’m wondering why they didn’t equip her with a (e.g. telescopic, as on Sovremenny?) hangar…

    But it’s the same in several sites and seems to be a photoshop (look at the “260”)

    It IS photoshopped (poorly).
