HexHead -> RE: ASW Air is FUBAR (5/29/2011 6:18:58 AM)

If i may, I would like to introduce some RL iformation here. First, I am not a submariner, but I worked at Portsmouth Naval Shipyard and have had a lot of conversations with submariners. I also, since I was a kid, have done a lot of reading on the subject - decades. I also have played the Silent Hunter series a lot. I know the US experiences in WW2 very well and am knowledgable about the German service. * From the beginning of the Pacific War, most, not all, boats at the start, had air warning radar. * From my SH experience, particularly in SH IV "ver 6", this is the routine: 1) Any air contact - crash dive immediately (unless you're in shallow water, which is another can of beans to start with - this applies to the Java Sea and other spots). Resist the temptation to shoot it out - that is folly, just folly. The small arms are there for emergencies only. Crash dive at flank speed. Do not maeuver, just get her down as quickly as you can at flank. 2) With any boat, I am at 40' in 35 seconds, 60' in 50 secs, and at the crucial 100' in 75 seconds or less (visibilty drops sharply at 100' and below). I dove at flank, so on the surface from a cruise of 9 kts, I dove at about 11 - 12 kts, and my momentum plus flank submerged means I am still at 7 - 8 kts, minimum. 3) I have maintained course and not lost way. Get down to 165' - aerial DCs are still a headache at 150'. 4) At 165+ feet, maneuver sharply to starboard or larboard, to get at about 30, 45, or 60 degrees from the original course. Maintain flank. 5) Run for about another minute or so. Even before this step, my previous drill has put me roughly 200 yards away from where I pulled the plug (do the arithmetic - 5 kts is about 10 feet per sec). 6) Throttle back to 1/3. Go to silent running if desired. Stay on new course or establish another one, if desired. Run for one hour at 1/3. 7) Come up to 80' and listen. Come up to periscope depth. Raise the observation scope. Scan the sea and scan the sky. Do this thoroughly. 8) Surface. Haven't lost a boat yet. Few US boats were lost directly to enemy air assets - some, yes, and the chief factor seems to have been surprise. Enemy air can keep ypur head down and be the prelude to a nasty party with waterborne ASW, but good skippers shouldn't be losing their boats to airborne ASW. Again, I know the US service the best, but even Mark I eyeballs with a decent watch crew should give you just enough, just enough, to crash dive and be below visiblity and at least 100 - 200 yards away from your last position on the surface - hard to put that DC within instant kill range. Just trying to introduce a few considerations that I believe are realistic.
