Sigma have got a new competitor from Russia and it would be better for Vietnam to invest in these… The new design is based on the Pr.21631 Buyan-M, which is modified version of the Pr.21630 Buyan. These can definitely compliment the Gepards.
These would be very good for not just Vietname but also for Indonesia who have got lot of Islands spread across to patrol. The Russian option definetely would be cheaper than the European ones. Till now Russia did not have a class of ship to compete with Sigma, but it looks like JSC Zelenodlsk Design Bureau have come up with a right sized one.
Sigma <> Buyan-M

Sigma stands for Ship Integrated Geometrical Modularity Approach. The ship’s main dimensions are named in the types itself, SIGMA 9113 stands for 91 meters long and 13 meters wide, same is with the SIGMA 10513, 105 meters in length and 13 meters wide.
Indonesia has four 9113 class corvettes (1,692 tons) in active service by 2009 and in August 2010 has signed a deal to build frigate PKR 105 based on SIGMA 10514 in PT PAL Shipyard Indonesia. (2400 tons)
Morocco has ordered two 9813 class heavy corvettes (with VLS) 2075 tons and a light 10513 class frigate based on a modified design. 2335 tons
Vietnam has negotiated four SIGMA in October 2011 by Prime Minister Nguyen Tan Dung’s visiting to Netherlands. The Dutch Schelde shipyard in Vlissingen, Netherlands will build four Sigma corvettes for the Vietnamese Navy. The first two ships will be built in Vlissingen, and the last two will be built in Vietnam, under Dutch supervision

Noteworthy in this context:
Schelde is expecting to become even more integrated within the Damen Shipyards Group. Damen is planning to develop “more and better standard products” and will be investing in shipyards in countries with “competitive wages.” One such is Vietnam, where Damen is building a large shipyard that’s slated to start operations in 2010, which in the longer term will also provide opportunities for Schelde
This cooperation works both ways.

Damen Group has already delivered some Damen Stan 4207 patrol vessels for search and rescue missions.
The Vietnam Marine Police also cooperated with Damen Group to build large vessels with Dutch license, such as one offshore patrol vessel 9014, one hydrographic survey vessel 6613, four salvage tugs 6412.[7][8] These vessels will be built in Vietnam by the Song Thu company.
