Gepard-class frigate

These vessels are capable of employing their weapons systems in conditions up to Sea State 5.^{[citation needed]} The hull and superstructure are constructed primarily of steel, with some aluminium-magnesium being used in the upper superstructure(stealth technology). They are equipped with fin stabilizers and twin rudders, and can use either gas turbines or diesel for propulsion in a CODOG configuration.

Gepard is Russian for cheetah.

In October 2015, Dagestan, in company with three other Russian Navy ships serving with the Caspian Flotilla, launched cruise missiles at targets in Syria. The missiles flew nearly 1,500 kilometres (930 mi) over Iran and Iraq and struck targets in Raqqa and Aleppo provinces (controlled by the Islamic State) as well as Idlib province (controlled by the al-Qaeda-linked Nusra Front).^[1] Peshmerga forces (Kurdish armed forces located in northern Iraq) published a video allegedly depicting two cruise missiles mid-flight en route to Syria.^[2]

The Gepard-class was designed from the outset as a lightweight, inexpensive export vessel. Russia offers three variants of the class to the market:^[3]

• Gepard 3.9: designed to search, track and fight against surface, underwater and air enemy independently and within task force, plant mine fields, provide protection and patrol of maritime state border and exclusive economic zone, perform combat missions, patrol service. Powered by gas-turbine engines with CODOG configuration. Fitted with two inclined quadruple launchers for eight Kh-35 anti-ship missiles with alternative options to be featured with VLS systems such as UKSK (for cruise missiles such as Club-N and Yakhont) and Shtil-1 air-defense system.^[4] Being the only exported variant with Vietnam being its first and only operator.
• Gepard 5.1: configured as an ocean-going patrol ship. Intended for patrolling territorial waters, helping in distress on the sea, environment protection, support to marine missions and flag demonstration in areas being of state interest. Can be featured with "heavier" weapons if necessary. Powered entirely by diesel engines with a two-shaft CODAD propulsion plant.^[5]
• Gepard 5.3: designed to search, track and fight against surface, underwater and air enemy independently and within task force, carry out convoy missions and patrol duty, guard maritime state border and economic zone. Featured with four quadruple launchers for sixteen Kh-35 anti-ship missiles. Powered by a two-shaft CODAD propulsion plant.^[6]

In March and August of 2011, the Vietnam People's Navy received two Gepard 3.9-class frigates ordered in 2006, built in Russia at Tatarstan's Gorky Shipbuilding Plant. In late 2011, Vietnam signed a contract for an additional batch of two ships in an anti-submarine configuration.^[7] A further two ships are being considered to bring the total order up to six vessels, and that potential acquisition is likely being stalled due to sanctions towards Russia as a result of the Ukrainian conflicts.^[8][9][10]

Sri Lanka began talks for the credit purchase of a Gepard 5.1 frigate in 2017 and the Sri Lankan cabinet approved the proposal by President Maithripala Sirisena for the purchase of the ship in September 2017.^[11]
