In a collaborative effort with iXblue, NOAA, and the Center, DriX Autonomous Surface Vessels have been housed and supported by the Center since the December 2018. The DriX is a 7.7 m long, wave-piercing, composite composition vehicle, capable of meeting NOAA’s hydrographic survey specifications at speeds exceeding 10 knots. In addition, the DriX boasts an endurance of seven 24-hour days at 7 knots, providing a long-endurance capability not possible by most other vehicles of its size.

The Center facilitated the installation of an EM2040 multibeam system and a Kongsberg MBR long-range radio for vehicle evaluation and testing—both at the Center and in trials aboard NOAA vessels.
