That Sensor 2 is OK, since otherwise they wouldn't know where to go to find you to shoot at, once you submerge. Nothing quite like hearing the whirr of a torpedo you know you didn't shoot. It sure would be nice to have a "Incoming torpedo! Bear XXX, high speed!", but alas... Anyway, the problem lies with Sensor 3 and Sensor 4 there, which are the doubled entry, both of the same dates... flying fickle fingers of frustration...
