The Russian Gepard-class frigate or project 1166.1 were to succeed the corvettes of the Koni, Grisha and Parchim-classes. The first frigate of this class the Yastreb was laid down in 1991 but not earlier completed as four years due to budget problems. There were five different options of this class available for foreign navies.
The Vietnamese navy choose for the variant fitted out with a hangar and 1x Kortik CIWS on the fore ship instead of the standard 2x30mm 6 barrelled AK-630 guns. Further more are these ships standard armed with 2x4-launchers for SS-N-25 Switchblade anti-ship missiles, 1x2 Osa-M surface to air launcher for which 20 missiles were available, 1-7,62mm gun, 1x12 barrelled anti-submarine rocket launcher, between 12 and 20 mines and 2x2-533mm torpedo tubes.
The standard specifications are a displacement of 1,500 (standard)-1,930 (full load) tons and as dimensions 93,5 (waterline)-102,14 x 13,09 x 5,3 metres. The Gepard 3 variant had however an increased displacement of 2,100 tons while full load just liked an increased beam of 13,8 metres. The two gas turbines supplies 2x29,300 shp while the one diesel engine supplies 8,000 bhp allowing a speed of 28 knots with a range of 4,000 nautical miles by a speed of 10 knots. They are fitted out to stay at sea for a period of 15 days. The crew numbers in Russian service 98 men.

The Vietnamese frigates were built at the yard of the Tatarstan’s Gorky Shipbuilding Plant (Zelenodolsk Factory) in Russia. The first one the Dinh Tien Hoang with pennant 011 was laid down on 10 July 2007, was launched on 12 December 1010 and commissioned on 23 March 201l. Her sister ship still without official name but with the pennant 416 was laid down on 27 November 2007, launched on 16 March 2011 and will probably this year be commissioned.
