Agent Jiang; as you know, an important Chinese surveillance vessel was lost in American waters. Your mission is to destroy derelict submarine SSN-37-1A before the Americans can recover and analyze it.Espionage debriefing

The SSN-37-1A (called sub recovery site in the Pip-Boy map) is a covert Chinese submarine in the water off the coast of Point Lookout in 2277.


The vessel was in the process of being recovered by the U.S. military pre-War. It can be found at the sub recovery site. One Chinese submariner was captured from the sub, noted as John Doe. He was transferred to Turtledove Detention Camp after his capture. The report states that his skipper had killed himself and the submariner would have as well, but the cyanide capsule in his molar was a dud.[1]


Mission parameters:
Routine Patrol/Observation

Vessel SSN-37-1A is ordered to patrol hostile waters between:
+38 3' 36.00", -76 18' 36.00"
+37 49' 41.61", -76 0' 37.02"
+37 5' 60.00", -76 1' 12.00"

Variations from patrol are tolerated as required by evasive circumstances. Crew is under strict instructions not to engage enemy if detected. Self-destruct protocol must be initiated in event of imminent capture. Status updates are required at six hour intervals by one-way burst comm on orbital frequency #K17.18.v121.


Above the waterline are a small stranded boat and a buoy. Below is a medium-sized submarine with a hatch on top. There is one accessible room, with two beds. The ladder leads straight into the roof and a pipe spraying water is also severed at another point but not leaking. There is a mainframe computer at the forward end of the chamber, and a generator leaking a green substance. Irradiated water covers the floor.
