Destroyer escort AI.  I had an AI controlled destroyer working alongside me to protect our little convoy.  This guy was a madman.  He was able and willing to avoid collisions with ships in the convoy, but not with me.  He nearly rammed me2-3 times during my little playthrough session.  Again, others have noticed this behaviour as well and some have said they've lost more scenarios due to friendly AI collisions than from enemy action.

I lost the tutorial due to a collision with an allied vessel. I didn't even know there were allied vessels in the scenario.

Is this something I want to get now, or should I wait until it goes on sale ? (10% isn't much of a discount).

Having said that, Daedalic is one of my favorite publishers.  They generally don't produce simulations but do produce good quality games.  I'm especially fond of what they did with their Aventuria games (The Dark Eye: Chains of Satinav, Memoria, and the two Blackguards games, warts and all) and the Shadow Tactics: Blades of the Shogun series. The downside is that sales are not all that frequent.

Daedalic paid quite a lot to secure this deal (several times my own budget) so I wouldn't expect them to squander any opportunity to get an extra buck. At the current rate they will need many months to break even with their original investment, or at least the number was made public about it.

Fortunately they're backing a game obviously made with much love & expertise when it comes to the contents & the history, I do sincerely wish everybody the best of luck & success in the months to come  :bd:

Starting to get the hang of the TRR sonar/depth charge targeting system (even though I still don't fully get how the speed gauge point in the bottom right is supposed to function.)

Managed to sink all subs with zero convoy losses.

I set up a scenario where it was my lone destroyer trying to protect 4 merchants from a single U-boat during a rainy night.  I find I'm able to drive him under and keep him there without too much trouble but scoring hits with depth charges is very difficult.  You need to create distance in order to line up a run at a good angle but creating that distance takes too much time and he might be able to get some torps off at the convoy in the interval.  I fund I'm constantly coming in at garbage angles and dropping nuisance spreads just to force him to make turns to avoid until I run out the clock.

Much easier with a corvette buddy and some air assets.

SDR, that was even a raging debate within the escort groups themselves.  "Am I there to hunt U-boats, or to protect freighters?"  By mid-1943, I think the strategic thinking had shifted to the latter, but good ASW commanders still developed a feel for when to prosecute a contact versus just forcing a U-boat to run and hide.  There was definitely at least as much art to it as there was science.

Silent Disapproval Robot

Oh, I want to prosecute them until they're nothing but oil slicks on the surface.  It's just that lining up for a run and trying to guess which way they'll turn is very tough to do.  I'd guess my ratio of depth charge runs vs. hits is 40:1 or worse.

Based on your post, I was wondering how effective depth charge attacks were in real life.

I found this very interesting official US Navy report. Some really cool info in here:

Yeah.  The British gathered some pretty extensive statistical evidence on how far apart depth charges should be spaced to maximize your chances of damaging an enemy sub, and even that was a hotly debated topic for the first several years of the war. 

This was a particularly relevant topic in the ranks of air-based ASW forces, as they typically had (many) fewer depth charges to deploy in a single instance than a DD or a DE might.

The math was certainly in the sub's favor for avoiding any single depth charge.  Of course, you can usually say the same thing about the odds being in the soldier's favor for any given bullet.   :(

According to the report I gave the URL for above, a 'volley' of nine depth fused charges from side or stern drops only had a 6% chance of killing the sub (see Table 4 in the report).

Interestingly, hedgehogs (forward shooting) and proximity fused charges had an effectiveness of over 20%.

Hedgehogs were more accurate because they were fired before the submarine entered the shadow zone, so when they were launched, they had both a range and a bearing.  Additionally, they didn't have to be set for a particular depth: they detonated on impact, so a 3D problem using depth charges became a 2D problem, and both the the dimensions were known, more or less accurately.

Wow, I feel like a dog chasing my tail. I've set up a scenario with one ship in the "convoy," one AI escort and one sub. I've got a few depth-charge runs at the sub. Crashed into my convoy and my AI escort. I'm still having a blast learning how to operate all the combat trackers. I hear the AI sub is too fast and a patch is incoming. I believe it. Max submerged speed should be about 7 knots. It's acting more like an Akula class.

Finally got a win. Only took 7.4 hours of frustration. Got a good depth charge run, u-boat surfaced, then finished them with the five-inch guns.

Silent Disapproval Robot

I've yet to get one with my guns but I've sunk 8 with depth charge runs.  I still haven't managed to repeat my first success when we (me and a Flower class corvette and a Catalina controlled by the AI) managed to sink all 3.
