I could have sworn it was in, 'Clear The Bridge', however I have read so many books - it could have been a different Skipper.

Whomever it was wrote that upon reaching his assigned area, he tried 'All Stop' and performed high-scope & radar searches at that location all day. The next day he would move 20 nm, and conduct the high-scope search at the new location all day, sail 20 nm the next day, and repeat the procedure until he found a contact.

Sadly, unlike SH1, SH4 doesn't model the larger horizon gained by using 'high-scope' searches, although in real life many patrolled using the high-scope farther horizon advantage.

What SH4 does correctly is model the almost daily position reports the Japanese (and Germans) were required to report. These reports would be intercepted and decoded becoming the ULTRA reports our Commanders received, and that We receive in-game as the red boxes with directional tails on our chart/map screen, along with the position report messages. This is why it doesn't bother me that those position reports are on the Nav map, although of course there are too many in Stock... (as was the case in SH1)

Unlike the Axis, US boats did as little communicating as possible - mostly none - because they were the 'silent service'. The few US wolfpack missions required some communication between the boats, and a small handful of boats reported that they were under attack, however most did not even report that. After a period of time they would be declared overdue and lost at sea.

This topic, "The mathematics of roving searches" is very interesting and is interesting to compare with the above static search method that conserves some fuel.

I've been a fan since the excellent tutorial on how to make a torpedo attack without the use of a TDC (S-boats didn't have a TDC) written by someone whose initials are, 'Frank Kulick'.

Happy Hunting!
