History: 
Designed by Zelenodolsk Design, the 900-ton class Project 21631 Buyan-M is a stretched version of the 500-ton Buyan class corvette (Project 21630) that includes more sophisticated weapons (VLS cells with Kalibr-NK system with P-800 Onix) and the ability to perform anti-surface warfare (ASuW) combat missions with secondary air defense capability, thanks to four Igla-1M surface-to-air missiles (SAM).

The Russian Navy plans to produce a considerable number of this corvettes to be delivered to the Caspian Sea, Black Sea and Baltic fleets.

Hull:
The model is cast as single waterline resin hull piece with acceptable moulded details for a such a small model. Given the fact this is a waterline model, the quick works (immersed part of the hull) are not represented. Buyan-M-03

Decals:
Unfortunately, the decal set included in this model is completely useless. Although pennant numbers and names in Cyrillic for the first 5 ships of this class are included (021, 022, 023, 602 and 603), all decals are blurred. The photo of the decal sheet speaks for itself, regarding the quality of the decals. Buyan-M-12
Instructions:
The instruction sheet is a fairly simple but provides a complete and clear guide to the correct location of all parts.

Painting Scheme:
The WEM Russian Baltic Fleet Grey M20 is the correct option to paint the hull and “vertical” surfaces and the decks should be painted with the Russian Deck Red M13, both paints produced by WEM Colour Coats.

The Vallejo Colour 982 Cavalry Brown is my suggestion to paint the red colour below the white water line. 

Just like other Russian warships models, due to thickness of the water line, I strongly recommend the use of a very thin white decal stripe, however, but only after painting the black area of the hull.

Conclusion:
This is a pretty straight forward to build model that requires however a few modifications in order to produce a more accurate model, namely the addition of:
  • Life rafts
  • Rails on VLS deck.
  • PE anchor chains at the bow
  • PE life buoys. 
I also modified the position of the white AFT dome installed on the small structure close to the AFT Komar SAM mount. The lack of a decent decal sheet is indeed a serious and annoying hassle nowadays. A welcome kit for all naval modelers looking forward to complete their Russian warships fleet at 1/700 scale, available at NNT Modell
