    Kopyo-F:

    Kopyo-F is the next-generation evolution of the Kopyo radar. Weighing just 75kg including its phased array antenna, Kopyo-F is intended for retrofitting to older aircraft, equipping light combat aircraft and may be installed in the tail of new Sukhoi Su-27 family aircraft for detection, tracking and target aquisition of pursuing targets. The radar uses a non-equidistant rather than the traditional linear radar field distribution, which allows a fivefold radar cost reduction over a conventional phased array while retaining good radiating characteristics. Kopyo-F features increased jamming resistance, and covert operation modes. A coherent TWT transmitter is used, with three basic types available, 1000w, 400w, 150w, depending on host aircraft. Using both programmable data and signal processors the available processing power of 900mflops is only currently operating at half capacity, giving plenty of room for future improvements and guaranteeing no overload of the system when tracking multiple targets.

    Weight: 75kg
    Volume: 165dm3
    Power required: 1.8kVA AC, 0.25 kVA DC
    Antenna: 0.44m diameter, ±70° coverage in azimuth and elevation. 28dB antenna gain.
    X band (16 distinct frequencies)
    3 receivers, 2dB noise factor
    3kW peak power output, 0.3kW average
    200hour MTBF

    Performance
    Lookup range 75km head-on, 30km pursuit
    Lookdown range 70km head-on, 20km pursuit
    20 targets tracked, 4 engaged simultaneously.
    Destroyer detected at 200km, missile boat 100km, railroad bridge 80km, moving group of tanks 20km
    ground mapping modes
    Low resolution : 80km (300m by 300m)
    Medium resolution: 60km (30 by 30m)
    High resolution: 60km (10 by 5m)

    Not bad for a small radar for a Mig-21 sized nose.

    I think the best option for the PAK-FA in terms of weight and size is something like the Mig-29/Typhoon/Rafale/F-18E/F and I am sure the Russians can achieve the same performance. The Typhoon/Rafale are pretty light, powered by two medium thrust engines. A bigger aircraft the size of F-15/Su-27 would just be unaffordable. A multirole in a medium weight would be pretty competitive. I think with modern technology, they can achieve similar performance with a medium fighter compared to an older Su-27 or F-15, kinda like what Typhoon and Rafale have done.

    I am not sure, but as it seems RuAF is now going with the N011M for their Su-27SM upgrade rather than the Zhuk-MSF. IAF has gone for the N011M instead for their Su-30MKIs.

    the F-35C will be rather fine aircraft probably, but what really bugs me is WHY would they give the F-18E/F the task of Air Defense, when it is a slow interceptorand F-35 the task of bomb truck. Not only USN does NOT need 2 multirole fighters when a single one can do it too, but in this case why not give F-35 the task of Air Defense since it’s a much better fighter, it’s stealthier, faster while give the F-18E/F the task of bomb trucking since it is much better for that role than it is for AA, and considering it can carry a large load, while the F-35 will be stuck to 2 JDAMs in it’s bays and in the future SDBs which too on F-18E/Fs racks can be accomodated in large number.

    F-18C/D is both Carrier and Land version, same with Mig-29, the M/SMT is land and K the Carrier. When it comes to the Carrier aircraft, in the future the F-18E/F and Mig-29K will be the main Air Defense fighters of their fleets. (No, F-35C is not going to be for USN because it will be largely a bomb truck and F-18E/F will undertake all the Air Defense with E-2C 2000s)

    There are currently around 7 Asian Fighters, the JH-7A(yes, it’s to be fitted with the same radar as that of J-10 I think), FC-1, J-10, LCA(in development), Ching Quo, F/A-50(in development) and F-2. Out of all of these, the F-2 is probably the most capable technologically because of it’s avionics and rather the most expensive. In the future, these are bound to face each other. LCA vs FC-1, J-10/JH-7A vs Ching Quo and possibly F-2 and F/A-50.

    I agree, they should get rid of the Embargo, it’s rather hypocritical, they say they dont want to trade with Cuba because of the Cuban Missile Crisis which took 40 years ago, cuz Castro is a Communist and has alot of human rights issues. I say the first one is bunch of crap and just another excuse, while the last two are just plain hypocritical considering they trade with Communist countries like China and Vietnam and many other non Democracies.

    It’s rather easy to denavalize a Carrier fighter than navalize a land fighter. Besides YF-17 being twin engined was one of the reasons it was picked over the YF-16 but I have also read that during studies, the navalized F-16’s landing speed was pretty fast therefore a lot of modifications would’ve taken place and the Carrier F-16 would’ve offered no commonality with the land F-16s, at least not much. Despite the little commonality, the F-18 despite being little more complex and heavier was twin engined and had little more range I believe.

    As for F-18E/F, well aerodynamically its a screwup, and Rafale is a much better Carrier Fighter. However the big advantage it offers over the Rafale currently is the fact the F-18E/F is almost fully developed, and AESA will be integrated in the future, while Rafale has a LONG way to go till F-3. Despite this, both of these planes are rather expensive, the F-18E/F was offered to Malaysia for 80mn, while they picked the much more capable Su-30MKM for a MUCH smaller cost. Rafale is not any cheaper than the SH.

    Now as for F-18E/F, I am not sure but I know with the F-35C they will replace just about every other combat aircraft on US Carriers except E-2Cs I believe.

    The F-18C/D vs Mig-29M/SMT has been discussed to death. Both of the planes are similar, in weights, range, payloads, number of hardpoints and etc. The Mig-29M has not been exported anywhere yet except the Carrier version Mig-29K for IN. SMT has received orders from Algeria and Yemen while the Russian ones are being upgraded.

    Anyways, it depends how you want to compare it. Do you want to compare future IN Mig-29Ks & RuAF Mig-29SMTs vs Finnish/Swiss/Malaysian F-18C/Ds or do you want to compare their overall multirole capabilities or whos better to a customer?

    I am just not sure Cuba should really sustain such an Airforce and such. Why? No matter how many fighters they have, it will never be enough against something like the US. They can have 500 Mig-29SMTs but eventually the US will take that down. I am not saying they should scrap their military all together, but what they could do is buy 2-3 SAM batteries like S-400 for Air Defense and a few supersonic jet trainers for simple air policing and such for Air Defense. With a limited budget, you have to be smart how you spend your money. I don’t think there is a need to keep any of those Mig-23s or -29s in service.

    I figured AAA will have a lot of problems against low flying cruise missiles, considering there will be a lot of stuff in the way.

    How about Vehicle mounted MANPADS radar cued by different sensors? These are cheap, about 2 people would need to man each vehicle, a driver and a weapons operator while they would receive targeting info from nearby surface radars, ships or AWACS.

    I would love to see some Libyan G-2 Galebs and some Sri Lankan Pucaras.

    Why doesnt the N011M have chance for the Chinese MK3? Also, what about the Zhuk-MSF, it seems to be Phazotron’s best radar for Su-27 class planes?

    As for Kopyo and Zhuk-M, the Kopyo is a very small radar, though the Kopyo-F in the future will come in small(for small nose), medium(for noses like that of Mig-29 & FC-1) and large sizes(for Su-27 and J-8 nose like planes). However Kopyo-F still has a while to go. Zhuk-M is a rather meidum sized radar for Mig-29 and FC-1 type plane with much bigger performance.

    Wouldn’t you use a ARM against SAMs and radars? Considering a Kh-31P like weapon is very fast and such. BTW isnt Kh-59MK subsonic and low flying?
