[Beardy Bob Black]

If you get the chance, sacrifice a good opportunity to test if you are being detected or whether the convoy is just following standard procedures.

Get into a good intercept position and go deep - at least below the thermocline.

Sit stationary and at silent running.

If you are being detected then the convoy should bear away from you - if not then they will pass you.

Remember that sometimes the DDs will be pinging but this does not mean they have detected you.

XO, bring me the earplugs and set for silent running ...
