This old hull was designed before the creatures of the abyss were known dangers, when it was assumed the oceans were safe-ish. Production of many had already begun by the time danger was discovered and, as such, these subs still see common use in the more secure portions of Europas oceans... Only the broke and stupid would dare take it to deeper, darker waters... This one in particular was sold to you by a some shady lookin clown... It was the only sub your crew could afford...
