Searching videos where someone is escaping destroyer hunts

MCM · 05-31-15, 04:36 AM

Hi,

after modding SH5 with IRAI the AI is kicking my ass badly. Unfortunately I only find videos where ships were attacked but nothing where uboots get tagged by hunters and the try to sneek out between all the waterbombs.

Would be very helpfull to see some videos with modded AI and how they survive.

Are you talking about how to escape from destroyers? I'm not an expert at how the expert crews are in the later game but there are some basic steps you can do to escape destroyers.

First thing you can do is dive under the thermal layer. I am pretty sure it's modeled in the game. I think it is around 50m (can someone clarify?). Being under the thermal layer makes you more difficult to detect with ASDIC. Once you dive deep try doing silent running and run at 1kt, switching your direction every now and then.

When a boat passes right over you, you can try exploiting the sonar weakness that is directly behind the destroyer. When it's above you go to flank speed and hard to port or starboard. As it gets further go to all stop and let the boat coast. I have had some success using these techniques.

Here are a couple of posts from another thread that may be helpful.

Not sure where a specific SH5 Youtube video on this subject but this old 1957 movie might give you some hints!

Shaefers videos are bound to cover this at some stage in the future I'm sure, so check them out it you haven't already because they're informative and entertaining! http://www.subsim.com/radioroom/showthread.php?t=220069

you might be able to help me with another problem I'm having although
having the extra depth will help now.
I can't seem to ever escape from the escorts

I've been trying this method

Crash Dive to 120m when detected deploying decoys at 40m
at 100m depth enable silent running and set speed to 1 knt

If I get pinpointed , flank up to 50m , decoys , dive 100m 90 deg course change then silent running. I try to offer low aspect when pinging but as you know not much maneuvering power at low speed.

I just don't seem to be able to get away If more than 2 escorts.
Iv'e had SH5, 4 , 3, 2, and 1. Sh5 since day 1 although I go through long
periods of no play I recently got the game running stable and mods how I like but I don't recall the escorts being so hard or have I just been unlucky.
I realise the escorts vary from dim to expert.

thanks

Stew

Always try to go as deep as possible ; ASDIC becomes less effective the more water you have between it and you. If you're near the coast and in shallow water, move in as close as you can to the shoreline ; the AS operator has more background hash to discriminate out as there's more things to bounce the ping.

Deep water is a double edged sword in "TWoS" ; deep water allows more scope for maneuvering and avoiding detection, but if you're badly damaged and sinking, and the bottom is deeper than your crush depth, it's goodnight!

With Vdr's R.S.D mod, at least you have a chance in shallow water to just sit on the bottom if your boat's been badly damaged and unable to stay afloat, and just wait it out until the crew can do enough repairs to hopefully struggle your way back the surface.

Never use E-motor settings above silent speed unless you're in grave and imminent danger of your day being seriously ruined by a wasserbomben dropping directly on your head ; only then "knuckle" or "Double knuckle" as the DD passes over the top, preferably to the opposite side that you anticipate his next run will be. This is the time to release a decoy if you have any.

Be aware that every time you maneuver at settings above silent speed, there is a high probability that a positive contact will be made by the Hunter group. This will result in resetting the A.I's "30 minutes on station from last contact" back to zero so you can guarantee at least another half hour of stress playing cat and mouse before they lose interest and move on again.

Groups of Hunters normally work in concert with each other, some quietly listening while others are running search patterns and randomly depth charging to see what pops up ; the A.I can be quite devious at times due to TDW's IRAI mod.

For example, recently during a patrol along the Southeast coast of Britain, I stirred up a hornets nest while attempting a running gunfight with a small freighter close to a busy port. Nine Destroyers, a PT boat and a couple of planes all converged from different directions to gather at the scene of the crime. This was the start of one of those "skin of your teeth" survival epics that I mentioned previously. Our poor little U-boat was hunted, harassed, hounded and pounded for bloody hours before they finally tired of their fun and must have unanimously agreed that they had more than likely killed us and decided to call it a day.

Meanwhile, down in the cold murky depths, a growing sense of relief was starting to prevail among the shaken crew. Our young sound guy Benno, was making absolutely sure there was no misunderstanding about what he was trying to tell us, because he told us over and over again, which was that our tormentors and would be assassins were racing away at high speed toward the distant horizon! After waiting for what I considered a reasonable amount of time, I ordered the boat to periscope depth to take a look around. Sure enough, the task force was fast receding off into the distance, each belching tall, twin columns of black smoke.

While looking through the scope, with that warm and fuzzy feeling building as it does when you have just been proven the better warrior and superior example of the species than your adversaries, I decided to take a precautionary sweep around before surfacing. Turning the scope leisurely through the starboard sector, my view was suddenly greyed out at the 180 bearing by a solid wall..... I froze!

Holy crap!!....sitting almost on top of the stern tubes was a dirty, filthy, deceitful, stationary and very silent warship!!

The trap was sprung! They must have spotted my periscope at the same time as my coronary shifted to the acute stage because all hell suddenly broke loose with their siren whooping and me screaming "ALARM!....ALARM!" to the crew.

As you all well know, even at periscope depth, nothing happens with any sense of urgency when trying to crash dive from a standing start!

Fortunately for us, the short range made it near impossible for DD gunners to depress the big guns down enough to draw a bead, but they stung us with smaller calibre fire before we finally managed to slip further under the waves and out of gun engagement range. Eventually as our E-motors built up a head of steam, our crash dive started to resemble the real thing so we powered down into the depths at flank speed until even the extended factory warranty was exceeded, switched to silent speed and then headed off in a completely different direction. Our deceitful adversary however, wasted no time calling his angry smokey compatriots from the distant horizon, because they were back on top of us in double quick time hellbent on destruction and mayhem, bringing on a very serious case of Déjà vu to us poor sailors.

Needless to say, we did eventually manage to somehow survive the day after a fashion. They achieved the next best thing to killing us, i.e. by damaging our boat to the point of being unable to complete the patrol and forcing us limp back to our home port for repairs.

So there you have it ; any engagement between your U-boat and surface warships can just end up a case of how the cookie crumbles or the mop flops....Sometimes you win, sometimes you lose and sometimes you draw!!

One thing I would modify to your tactic:

Quote:

90 deg course change then silent running

I would go to silent running before making the course change.

I order flank speed till I get the best possible speed, cut the engines to silent speed, and then use that momentum to get the turn started. Rudder hard to port/stb bleeds off speed too quickly so I usually manually input the rudder to 20-30degrees as a compromise between agility and speed.

To the AI, you are (hopefully) a lost contact that is still on the course you were on before going silent and turning. That's how I shake em' because usually they sweep your last known course trying to regain contact.
