    Even a dozen attack helos properly employed can make a huge difference in the sort of small front the rebels are attacking on right now @ Aleppo (not including the ISIS push to the south) IMO.

    Since they failed to identify and stop the counteroffensive when the rebels were approaching in the open towards this 1070 apartments project at the start of the offensive, I don’t think they’ll be able to do much if the rebels manage to break out of it to the urban areas. The positive thing for the regime is that the projects seem somewhat isolated from the neighborhood areas (major highway to the north, military objects to the east) so they might be able to contain further advance given sufficient defensive lines and support.

    This map shows several axis of attack south of Aleppo.

    Rebels need to counterattack in Aleppo, perfect opportunity for VKS to find large, concentrated targets. Ka-52/Mi-28s should be patrolling nearby regularly.
    Government needs to keep focus in the area, not stupid offensives like in Rakka.

    A few attack helicopters and bombers can’t do much on their own; if the rebels mounted enough troops for the offensive at multiple points, the government besiegers of the rebel part of Aleppo might become besieged pretty soon as their position in that long pocket is hardly sustainable, especially with their limited resources.

    So the primary advantage of Mi-28 is its protected againist 14,5 mm rounds plus 20mm HE-FRAG shells, instead of “just” 12,7mm in cockpit area (other vitals like engines are still protected againist 12,7mm IIRC). Hence my comment that Mi-28 brings a greater cockpit armor againist 14,5 mm rounds but the drawback is, non-armored (should have written insufficently armored) parts of the airframe are also more likely to get hit than a smaller helicopter.

    Do you have any data to prove these claims about the significant increase in hit probability? The small difference in size seems completely insignificant at range, while the offset in sensors, payload and armor is significant to those air arms which can afford the heavier helicopters.

    A lighter chopper with better T:W ratio engine would certainly be more agile , Apaches or Mi-28 wont survive a half decent AD system of enemy when put to test , A Ka-52 design with co-axial rotor is a better compromise between Survivability/Agility ….heck it even has an ejection seat. Other then that a design like Cobra or Indian LCH is a better way to go.

    The lighter helicopter is more agile obviously, but the rest are just generic and unargumented claims. Why wouldn’t the heavier gunships survive compared to a lighter helicopter and in which conditions exactly? Cobra is a better way to go for whom?

    You don’t think there’s a reason that those nations who can afford to, opt for heavier gunships?

    That thing looks too bulky to me to be useful for agile combat , In War for anti-terror operation it looks fine as they wont face any capable AD , Why dont they develop something along the lines of Cobra or LCH type chopper and keep the heavy role to Ka-52 ?

    So, you’re saying that Cobras being more agile than Apaches should be noticeably more survivable against a capable AD? I guess the US Army didn’t get this memo. 🙂

    But, seriously, I’d expect that a lighter, cheaper to operate and more agile helicopter would make more sense for anti-insurgency operations, rather than the other way around, IMHO.

    Out of curiosity, was has happened with Vikrh?.

    I remember some production delays by the Kalashnikov company, but those should have been resolved by now IIRC. Perhaps they’re just getting rid of the radio-guided Ataka stocks?

    Old news. It has been comapred right after so-called ‘888-war’ with Georgia. Of course, since that war some of Tu-22M3 recieved an upgrade of its targeting system, based on the same SVP system by Gefest, and it’s a great system, but it’s not like it can replace or even compete with PGMs when we’re tallking about combat effectiveness per sortie or weight of delivered munitions. But the main question here(at least for our RuAF) is a price and quantities of PGMs in service/arsenals.

    I’m not saying it’s “news” per se, but I thought it might be nice to compare these recent videos since there were some posts in this thread regarding cost/performance of these unguided bombs vs. PGM’s.

    E.g. in the Tu-22M3 videos, some of those target locations were not effectively struck (e.g. Arak, thanks TR1 for the analysis link) since apparently only one bomber was attacking that location.

    Tu-22M3 striking targets around Palmyra.

    Off-topic, but I thought it would be interesting to compare the effectiveness of a strike on some supposed IS facility with guided bombs by NATO forces.

    Not so sure about that^^

    Looks to me the Short range Mig-29 had its place in the Soviet Union Airforce.

    The requirements supposedly asked for an 800 km range at low level and 2750 km range at high altitude, but for production 9.12 airplane, those values were 700 and 2100 km (according to the data in Y.Gordon’s book).

    And of course it had a place in the SU Air Force otherwise it wouldn’t have been recommended for operational service. 🙂

    Interestingly enough, the T-10-1 (the first Su-27 prototype) suffered from insufficient range as well (and some other issues IIRC) and had to be completely redesigned as T-10S.

    Its bigger than a Typhoon or a Rafale, and its roughly identical in size to a Tornado or a classical Hornet. The range problem with the early variants of the Mig-29 was a very low fuel fraction.

    The fuel fraction part is definitely more precise although that’s kind of implied by size as in available volume size rather than mere physical dimensions. E.g. I wouldn’t say that MiG-29 is significantly larger than e.g. Rafale, rather than slightly longer due to a different aerodynamic configuration used (i.e. the Rafale is using the compact canard delta configuration).

    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.

    Also oversimplification of “feeding one engine or two” is absurd. An F-16 with single GE-129 on full AB will easily consume more than twice the fuel of BOTH J-85 engines on F-5E. You can’t say F-5Es fuel consumption would be higher just because it has two engines.

    It’s a simplification of course, but it’s only absurd if you want to make it that way by comparing the MiG-29 with a light fighter with two small turbojets from the late 50’s instead of its contemporaries. Not taking the SFC and thrust differences into account, the numbers from the Eagle’s post clearly show that other two engine fighters of the same or similar generation and class had roughly 50% more fuel.

    The biggest problem with the 29 is that it is rather small for a twin engine fighter so it’s really hampered by high fuel consumption. And if external wing tanks are used on the variants with the standard wing (6 hardpoints), the weapon load is rather limited to say the least.

    the early su27 is comparable to the mig-23 in capability

    Say what? Pretty much the only thing they have in common is being limited to SARH missiles only, so by that brilliant logic everything without active radar missiles is “comparable to the MiG-23”. And yes, the basic radar antenna design is similar to that used on late MiG-23’s, but since the antenna is much bigger and it has better computers, they’re not really on the same level at all.

    Also, wasn’t that Sovershennyy or did they change the name?

    They didn’t. You can see it quite clearly on the hull. Must have been a typo due to similar names.
