Super Dvora Mark III 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 speeding up to 50 knots (93 km/h) in littoral waters thanks to its state of the art thrust vectoring control Articulated Surface Drives (ASD) while holding various armaments up to 30 mm cannons in its armory.[3][4][5][6]

[edit] Performance
The Super Dvora Mk-III craft features interception of sea target at high-speeds approaching 50 knots (93 km/h); 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]
[edit] Propulsion system
The propulsion system consists of two Detroit Diesel MTU 12V-4000 (4175 hp each)[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 similar to the most advanced fighter aircraft such as Russian Su-35/37. Beside those systems Mk III's are also equipped with ZF4650 reduction gears, Kamewa 63SII water jets and intakes.[3][6]
Their thrust-vectoring propulsion system allows Super Dvora Mk-III to function in shallow waters at drafts of 1.2 meters facilitating special operations forces delivery on enemy shores and catastrophe relief missions.[3][4][7]
[edit] Armaments
The Super Dvora Mk. III design is robust to allow for the installation of Typhoon 25-30 mm stabilized cannon, light or heavy machine guns, 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]
[edit] 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]
