Hmm, Chinese subs have been prowling around Guam.
The names have changed, but the game's the same. I used to make patrols out of Guam (aka Guambodia). Since Guam sits on the edge of the deepest place on the planet, the Mariana Trench, we always had exceptionally short maneuvering watches (Unlike anywhere on the East Coast). As soon as we had topside secured, we'd wave at the Soviet "fishing trawler", pull the plug, and disappear for weeks. The Soviet Union went bankrupt trying to find our Missile Boats. Now, it's the Chinese's turn.
