That vessel was delivered to the U.S. Navy in 1968, and later operated with the

U.S. Coast Guard on the East and West Coasts.

The 84-foot, all-aluminum Is- raeli boat will be capable of speeds of 50 knots when foilborne and eight knots when operating on its hull. A 5,400-hp Allison 501-KF gas turbine powers the boat when it is riding on its foils. An over-the-stern, precision geared transmission system with a 14:1 reduction ratio is housed in the retractable, steerable tail strut. The controllable-pitch, 4- bladed stainless steel propeller has a diameter of 52 inches.

Hullborne propulsion is pro- vided by twin 100-hp, retractable steerable drive units at the stern.

Hydraulic power from six 64-gpm hydraulic pumps, three on each gearbox of the ship's service gen- erator sets, drive integrally mounted Rexroth hydraulic mo- tors. Propellers are fixed-pitch, 3-bladed pusher type of 315L stainless steel, with diameter of 26 inches.

The electric plant consists of twin Pratt & Whitney ST-6 gas turbine engines driving 200-kw generators, providing 100-percent redundancy. The engine monitor- ing and control system provides real-time monitoring of 22 ship subsystems having 469 parame- ters and direct control of 16 sub- systems. The attitude control sys- tem provides automatic roll, pitch, and heading control; radio fre- quency height sensor, and digital attitude control.
