    Well MiG-23MLD has combat radius of about 600km? An early series MiG-29 (9-12) isn’t really much better. Internal fuel loads are almost identical (3319kg for MiG-23), fuel consumption probably roughly in same ballpark (R-35 has somewhat less thrust than MiG-29’s two engines, but it’s a turbojet). Dunno about drag, ’29 maybe less draggy even if you figure in effect of wing sweep?

    Reason MiG-29 had short range is that no more was required. They were to be operated by almost exact same profiles as MiG-21/23 (ground controlled intercept, slashing missile attack, return to base, repeat if necessary). Even designers thought that very unambitious.

    Saw this one as well and if they were to stretch the Khareef class out to say 115 -120m’s what we will end up with is a modern day Type 21 same size speed range it is not a happy thought and in no way a replacement for a type 23. however if someone said the navy was to get 10 type 26’s and 6 of these it might be ok

    Type 26 has become so big and bloated, essentially duplicating many of the Type 45 capabilities, that there is no way they can afford them in adequate numbers. Latest number is eight, and don’t be surprised if it’s cut to six.

    111 metres is about 3000 tons displacement, no? If they want proper endurance and seakeeping, capabilities are going to be modest. OTOH maybe they don’t need latest gee-whiz if it’s going to just hunt pirates off Somalia.

    What happened to Types 27 to 30?

    That looks like those new Russian riverine/inshore missile boats, sans the actual missiles.

    Today MiG-35 no doubt has more range than original MiG-29A, but same could be said for F-16;
    -A modern F-16 blk50+ or 60 has 4585 kg fuel with CFT, plus 4609kg with 3xEFTs (2x600gals+300gal), totaling at 9194kg. A MiG-35 will have ~5200 kg internal fuel, plus 3492kg (2x1150l + 1x2000l) totaling at 8692kg. Due to CFT and new 600gal tanks, fuel capacity improvement on F-16 is actually way greater than the MiG-29/35…
    -So a blk50 F-16 will definately have more range, plus it will be able to carry pretty meaningful payloads with 3xEFT; F-16 can carry 2xAShm or 2xARM like MiG-35, but also it can carry 6x anti-tank missiles, or GPS guided munitions, 4x Laser guided 500lb munitions 2x2000lb munitions or variety of cruise missiles.

    However, don’t the later F-16 variants have degraded range performance due to extra weight and more powerful engines? One often reads about F-16A’s spectacular range performance, but later models apparently necessite CFT’s to match that.

    I can’t find any volume size comparisons, but I wonder how efficiently were the designers using the internal space for fuel on the MiG-29? Besides the awkward auxiliary intakes (which seem to take about 650 liters on the MiG-29M), was there any other potential space? E.g. could they have crammed more fuel in its wings which might have bumped up the price? The casual search on the MiG-29M mentions fuel being fitted only to the enlarged spine, larger wings and LERX after removing the auxiliary air intakes.

    Edit: I checked up the Gordon’s book on MiG-29M variant and it mentions that the fuel capacity on the basic model was additionally limited due to the materials used and riveting whose joints could not be reliably sealed. On the MiG-29M, a new alloy was used which was welded, not riveted allowing for more internal space to be used for fuel.

    Yes, original MiG-29 used old-fashioned bag tanks which were quite space-inefficient. Later versions with improved structure use integral tanks, where entire internal structure works as a fuel tank.
    IIRC F-16 has one fuselage bag tank and rest are integral tanks. Newer a/c tend to be all integral tanks.

    An interesting quote.. 92 RD-33MK engines are valued at 8.675 billion Russian Rubles which is some $136.2 million..
    Why weren’t any spare engines ordered, BTW?

    Probably they were, but weren’t part of the factory order, which only concerns aircraft built?

    Reread the article. it says Chinese pilot has to do some calculations for BVR shot that often not accurate. how they came to know its not accurate or pilots are mostly key board warriors used to display screens than the old instruments.

    It means that when setting up semi-active radar missile shots, the pilots had to estimate by themselves whether enemy was in missile’s no-escape zone. This may lead to wasted warshots when it turns out enemy was not in range after all, or alternatively, flying to closer range than would have been necessary to achieve successful shot.

    Remember that those Flankers can’t intercept multiple targets, also their track-while-scan capability is probably quite limited so when taking a radar missile shot, they can do little else.

    So they flew several 4 vs 4’s and in one of them Flankers lost 0-4.

    A split F-35A/B fleet appears to be an RAF proposal, presumably so they’d have some F-35s which they could guarantee wouldn’t have to have anything to do with those horrible navy people. The RAF has a very long history of trying very hard to (1) control all UK military aircraft & (2) keep them all on land, regardless of military effectiveness.

    Say hello to air forces everywhere… 🙂
    Why would RAF want F-35B? It has less performance for more money. Sure they had Harriers before but I understood that those were pretty much forced on RAF.

    yall going ape **** over the 300 of 800 word article on Janes.
    What else does it say? anyone have access to the rest?

    I, and most others on the board, personally felt India should’ve NOT bought the carrier and build their own and operate Rafales and LCAs off them.

    Naval LCA is 5 years away at minimum, and it really looks like about same for Rafale…

    Also, MiG-29K is roughly half the cost of Rafale.

    If France helps get Kaveri running augmented – something the Russians were apparently doing already – would a Kaveri powered MiG-29M+ or MiG-29K make sense? We already know Kaveri was slated for AMCA, but that project looks less and less likely to ever happen in its current form. At least MiG-29 gives them a shorter term platform to build. It wouldn’t be a big stretch to see an indigenous MiG-29 variant powered by Kaveri and toting Astra AAMs.

    Didn’t French already offer help with Kaveri earlier and it was rejected?

    I think the much greater capability of the Su-24s on-board suit won over the cheaper single engine attack birds.

    Sure with conventional bombs (esp. when you figure in all-weather capability) but for PGM’s, MiG-27K and Su-17 would have worked fine for kind of operations like in 2nd Chechnya and Syria, while costing probably like half of what Su-24. Even in early ’90s it was obvious that PGM’s are the future. Also for tactical recon, in fact wasn’t that the last role Su-17 had in RuAF?
    Also those ships were new, newest just couple of years old when USSR collapsed. Poland’s still using theirs…

    edit. Finnish Air Force apparently briefly considered acquiring ex-GDR Su-22’s in early ’90s, to replace MiG-21 in recon role. Those a/c would have been almost new, for cost of scrap metal.
    However, Hornet acquisition ate up literally every penny.
