MJP 750 DRB waterjets. In total, MJP will deliver 45

OmniThruster shipsets over the next 10 years. Selected for its superior shallow draft maneuvering capabilities, the 750 DRB waterjets are constructed from duplex stainless steel offering the latest advancements in MJP’s proprietary mixed ? ow technology. Featuring an inboard hydraulic system and an integrated electronic control system, the selected propulsion package has been optimized to ? t the needs of the U.S. Army.

OmniThruster Inc.

For over 40 years OmniThruster has been a developer of waterjet bow/stern thrusters and maneuvering systems for maneuverability and auxiliary propulsion, specializ- ing in waterjet thrusters that operate ef? ciently in shallow draft conditions. Its HT Series in particular are capable of full power operation with only 3’ of draft. The HT Se- ries (200-600 HP) was developed to provide small vessels maneuvering and auxiliary propulsion capabilities. The unique design features a compact, conical chamber, which generates a helical ? ow pattern resulting in ef? cient energy conversion. This Heliconic approach effectively decreases
