Menurut penganalisis, pesawat jet pejuang ini selain ianya hebat dari segi kelajuannya dan keupayaaanya mendaki, ia juga sukar dikesan olah radar kerana menggunakan teknologi yang sama dengan pesawat pejuang stealth. Ia adalah katogari jet pejuang dari genarasi ke 4. Jarak simpanannya minyaknya melebihi 3,000 km (jarak penerbangan). Kelajuan maksimumnya menyamai MIG 29 sementara keupayaan mendakinya jauh lebih hebat dari mana-mana pesawat pejuang di dunia. Jestru itu tidak hairanlah jika pesawat jenis "multi role" ini boleh menjalankan tanggung-jawabnya dengan baik, tidak kira samada sebagai pengiring mahupun "interseptor"/pemintas.
Jika pesawat ini yang mahu dibeli oleh Malaysia untuk menggantikan MIG 29 kita, penulis tidak akan membantah, kerana sememangnya ianya lebih hebat dan dikatakan terhebat di kala ini. Tetapi dari segi harganya pula, sudah tentulah kita tidak termampu, iaitu kira-kira hampir RM 500 Juta sebuah. Bayangkan untuk mempunyai sebuah skuadran kecil seperti skuadran F18 (8 buah) kita perlukan RM 4.0 Billion tidak termasuk alat-ganti, latihan dan kos penyelenggaraan.
Sekadar perbandingan sila lihat video dibawah. Ada sedikit kesilapan "taipan/typo error" Kelajuan semua jet-jet pejuang ini adalah melebihi 2.0 Mach. Mana yang kurang itu adalah "typo error", harap maklum. Jika diperhatikan Jet-jet pejuang Sukhoi SU 27, Sukhoi SU 30 dan Sukhoi SU 35 mempunyai rupabentuk yang hampir sama, begitu juga halnya dengan MIG 29 dan MIG 35. Pada pengamatan penulis model-model ini hanyalah model yang dinaik-taraf. Sehingga 2008 Sukhoi SU 35 (http://en.wikipedia.org/wiki/Sukhoi_Su-35) dan MIG 35 (http://en.wikipedia.org/wiki/Mikoyan_MiG-35) yang digunakan oleh tentera Soviet bolehlah dikatakan sebagai jenis model prototaip (kurang/hanya 10 buah bagi setiap model).

  2. I was wondering if you ever thought of changing the structure of
    your site? Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of
    content so people could connect with it better. Youve got an awful lot of text for only having one or
    2 pictures. Maybe you could space it out better?

  3. Hello! I just wanted to ask if you ever have any problems with hackers?
    My last blog (wordpress) was hacked and I ended up losing a few months of hard work due
    to no back up. Do you have any methods to stop hackers?

  4. Hello just wanted to give you a quick heads up. The text in your content seem to be running off
    the screen in Firefox. I'm not sure if this is a format issue or something to do with browser compatibility but I figured I'd post to
    let you know. The style and design look great though! Hope you get the problem resolved soon.
    Kudos

  6. Put your phone in your shirt or pants pocket Dockers makes pants with zippered pockets if
    you are into fashion and clothing research.

    Thread Magazine1 outlines the vast number of choices in
    fabrics, colors and styles. She should be able to match the situation
