Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
A US nuclear submarine, of the "Los Angeles" class, has been involved in a collision, about 560 km south of Guam.
To all agents:
Early reports suggested that USS "San Francisco" (SSN-711) had been involved in a grounding incident. Recent data relates that she was submerged, when she "hit bottom in one of the deepest parts of the Pacific" -- "the middle of the East Marianas Basin". One man died and twenty others were injured.
It is unsetteling that a boat with a test depth of approximately 1000 feet striking bottom in one of the deepest parts of the Pacific... True, she was probably running without active sonar, or even her fathometer going, but, still, the navigation systems (ESGN, GPS, etc.) used by the 688 boats have an accuracy of less than the boat's length, and the watch in the control room should have been plotting her course both electronically and on a paper chart (hard for a chart to break down or blow a fuse), with more than sufficient warning of seamounts or such ahead on their course.
Cell A is afraid that something did interfere with the boat's navigation or that the sub did strike some uncharted obstacle? (Uncharted, perhaps, because, prior to the recent "seismic disturbance" near Asia, said obstacle didn't exist? Though a bottom movement of this magnitude would have probably set off its own little tsunami...)
Did the "San Francisco" really hit the ocean floor at all?
Delta Green agents have been sent to investigate this unsettling collision in an area wich is classified as highly dangerous by Delta Green.
