The Bora-class, Soviet designation Project 1239, hoverborne guided-missile corvette of the Russian Navy, also bears the NATO class name "Dergach", is one of the few types of military surface effect ship built solely for marine combat purposes, rather than troop landing or transport. The first vessel produced under this designation was Sivuch, which was later renamed Bora. It is one of the largest combat sea vehicles with catamaran design.^{[citation needed]}

The weapons array Bora-class warships carry varies depending on which of several configurations it is built to. The specifications listed are for the two existing craft.

The Bora class was designed in 1988 mainly for coastal defense and patrol duties against surface vessels, large and small. Two were built and are currently in service, both assigned to the Russian Black Sea Fleet. A future series of hovercraft have been planned^[when?] based on this model for future production.^{[citation needed]}
