FUGUSUB

​​​​​​​​​​​​​​SPECIFICATIONS


Type of submarine:        Semi-dry, ambient pressure


Crew:                            1 pilot


Length:                          7 feet 8 inches


Width:                            72 inches (including thrusters)


Weight:                          Equipment loaded approx. 1,100 lbs.


Max operating depth:      Recommended 100 feet


Max speed:                    Approx. 3 mph


Propulsion:                     2 DC thrusters with combined thrust of 80 lbs.


​Power source:                1 VRLA (Valve Regulated Lead Acid) gelled electrolyte.                                            

                                                       12 volt 225 amp. hr. battery.  Battery upgrades possible in   

                                     the future.  Subs with tethered AC power are also possible.


Life support:                   Four 80 cubic foot aluminum scuba tanks, three of which have

                                                        independent regulators to breath from and one tank is used for

                                     sub functions.  one tank is equipped with a 20 foot extension

                                     regulator hose.


Communications:            All three subs are equipped with Ocean Technologies System 

                                                        (OTS) AQUACOM SS-B 2010 units with custom headsets for

                                     use in air pocket environment (cockpit).  Push-to-talk unit has

                                     4 channels.  Allows sub-to-sub, sub-to-diver communications

                                     with compatible units and sub-to-surface base station.  We

                                     currently use an OTS 8 channel AQUACOM SS-B SURFACE

                                     STATION.


NOTE:                           Pilot can raise voice and talk directly to divers or cameras and

                                     can be heard quite well through the acrylic canopy.

                                                                                                             

Visual capabilities:          1 acrylic half-hemisphere dome, 1 rear and 2 side viewports.


Pilot exit/re-entry:           Pilot can land sub carefully on bottom, put on a scuba mask,

​                                     let air out of the cockpit and exit the sub using an extended

                                     regulator hose.  Pilot can re-enter sub, lock down canopy and

                                     restore air pocket by purging a regulator and resume journey. 

                                     


Hull material:                  Fiberglass-reinforced vinyl ester resin composite.


Component materials:     Stainless steel, engineered plastics, fiberglass composites.


SPECIAL NOTES:          A sub with side-scan sonar could exponentially increase the

                                     search capabilities of these vessels in low visibility conditions.


                                      If a tethered AC power system was installed, more powerful

                                      thrusters could be used, eliminating the need to stop for

​                                      battery charging.                         

                                                       

                                                        Additionally, banks of high-powered lights could be added that 

                                     would drain any DC battery system quickly.  Fugusubs could 

                                     become relentless underwater search engines ideal for special

                                     ops.  Imagine the effectiveness of a coordinated group of them.
