The Dvora is a fast patrol boat of Israeli origin. It can be considered a lineage that started with the Dabur in the early 1970's and continues with the Super Dvora Mk III today. Although of US origin, all subsequent production and development is carried out in Israel. These fast boats are considered highly capable in the counter insurgency role. Except for the Taiwanese Hai Ou derivative with anti-ship missiles they are of limited use in coventional warfare.

All versions of the Dvora follow the layout of the original Dabur. These feature a superstructure and mast amidships, armament on bow and stern and two diesel engines connected to two shafts. The crew ranges from 5 to 11 depending on mission and armament suite.

The main armament of all early models were a 20mm Oerlikon on the bow and stern. These were supplemented with machine guns and depth charge racks. A number was fitted with tubes for the Mk 46 torpedo. Newer models are fitted with the Typhoon RWS on the bow, usually armed with the 25mm Bushmaster autocannon. A small number is fitted with a single AGM-114 Hellfire missile launcher.

The original Dabur had a modest speed of 19 knots. This was improved in the Dvora by fitting more powerful engines. The Super Dvora Mk II and Mk III feature even more powerful engines and have surface drives with thrust vector steering. The result is a 45 kt maximum speed and the ability to operate in very shallow water.

The Dabur was used in quantity by Israeli forces. With newer models entering service many have been sold to South American navies. All marks of Dvora have been actively used by Sri Lankan forces in the conflict with the LTTE. Large quantities of Hai Ou have been used for over two decades by the Taiwanese navy.
