An autonomous underwater vehicle system for ocean science measurement and reconnaissance is about six feet long and 13 inches in diameter and includes various improvements which make turn-key, networkable, autonomous or tethered operation in aquatic environments possible. The improvements include a platform independent computer and I/O architecture which permits use of CISC or RISC CPUs and turn-key vehicle operation by persons unversed in computer programming, a floating launch and recovery frame which protects the vehicle and also provides for correct and safe vehicle assembly, an external battery charging port and high speed serial port with provision for optional control of the vehicle and data acquisition in real-time through connection of a lightweight electrically conducting tether, a four part hull assembly including an integrated strobe and antennae tower on the forward hull section which emerges from the water when the vehicle is at the surface, a modular, removable nose cone to carry sensors, and a motor mount which protects the main hull from flooding in the event of thruster failure, and flexible control surfaces with dive planes located on the forward hull and rudder fins on the stern hull section. These features are combined to produce a versatile and flexible platform for making oceanographic observations during complex behaviors executed by the vehicle and for providing duplex computer network connections when the vehicle is at the surface.
