The screen shot illustrates the basic intercept approach based on a contact report. We see:
(1) The corridor of probability.
(2) Hourly positions based on 8kts.
(3) The double line shows where I think the convoy will see the sunrise.
(4) The convoy should reach the sunrise position in about 5.5 hours. We will reach the area base on the navigator in 3.5 hours.
(5) The circle gives us some idea where we should able to hear to convoy.
(6) When we reach this area will begin dives every 30 minutes to try pick up the sound of the convoy.
Once we can hear the convoy, we start plotting a detailed track and from their planning our attack. Generally, I have tried to stay beyond visible range (except in bad weather). So, that has meant giving the convoy 15-20km bearth. Now, with the convoy maybe being fitted out with radar this presents a problem.
What is the radar detection range of mast mounted radar? 12nm, 20nm, 30nm? Do we have any tables?
This alone could pose a major problem to my hunting of convoys, since previously sonar always gave me the advantage of long range detection. Perhaps, the advantage has shifted. Well, we'll see.
