The Super Dvora Mark III-class patrol boat is the latest generation of the venerable Dvora family of fast patrol boats or fast attack crafts (FPB/FAC). Manufactured by IAI Ramta in 2004[1] these vessels are capable of travelling up to {{convert|50|kn|lk=in|0}} in littoral waters thanks to its state of the art thrust vectoring control Articulated Surface Drives (ASD) while holding various armaments, from automatic grenade launchers, AGM-114 Hellfire missiles, SPIKE NLOS missiles, and 30 mm cannons in its armory.[3][4][5][6]

Performance

The Super Dvora Mk III craft features interception of sea target at high-speeds approaching 50 knots; long range missions thanks to its sea replenishment ability ahead of a typical four-day endurance; high maneuverability in both open ocean and littoral environment; steady sea keeping in a range of sea states and very callous weather; and the ability to incorporate advanced, stabilized, accurate marine arsenal and sensors. Taken as a whole, vessel displacement varies from 72 to 58 tons depending on the operation package.[4][5]

These vessels are fast and agile, and designed to reach and maintain high operating tempos. Its hull geometry provides constant sea keeping at all speeds, and a dry deck throughout high-speed runs and tracking down.[7]

Propulsion system

The propulsion system consists of two Detroit Diesel MTU 12V-4000 ({{convert|4,175|hp|lk=in}} total)[2] engines driving two articulated surface drives, which were initially designed for competitive speedboats. Arneson Surface Drive-16 articulating propulsion systems drives provide the vessel with thrust vectoring control. Beside those systems, Mk IIIs are also equipped with ZF4650 reduction gears.

Their thrust-vectoring propulsion system allows Super Dvora Mk III to function in shallow waters at draughts of {{convert|1.2|m|ft}} facilitating special operations forces delivery on enemy shores and catastrophe relief missions.[3][4][7]

Armaments

The Super Dvora Mk III design is robust to allow for the installation of Typhoon 20-30 mm stabilized cannon, heavy machine guns, AGM-114 Hellfire (Surface-to-surface type) missiles, SPIKE NLOS missiles, all of which can be slaved to state-of the art mast-mounted, day/night, long range electro-optic systems including Elbit/El-Op sensors and targeting systems.[2][4][5][7][8]

Developments

IAI-Ramta is currently working on a number of new configuration upgrade packages for the Super Dvora platform as Strike and Littoral Warrior, which consists of a variety of highly advanced precision weapon systems.[8]
