I'm having a lot of trouble with the Grisha's who catch a wiff of my scent when I'm creeping up to periscope depth at 3 knots. I was under the impression that Russian sonar in this era was largely crap. According to the database, the Grisha's are equipped with Bull Nose (MGK 335) sonars which have a max range of 15nm. The kicker is that this scenario takes place in '69 but the description of the Bull Nose says it's late 1970s technology.

My second problem is getting a signal from the radars. In some instances I traveled right up the coast line at periscope depth but they are not radiating. Is there something the scenario expects from the player in order to trigger them to radiate?

I don't know whether they had MGK 335 available back then (I don't think there is a perfect record of when what tech was rolled out) but in that scenario the best way to beat Grisha's is to steer wide away from them. Once they get a whiff of you, it's very much game over and they have a very solid array of sensors, but luckily with not very long range.

As for radars you just have to go along the coastline and get a bit lucky to intercept the radar signal, you only need 10 signals total and there are a lot more stations around the coast.

Hi HaughtKarl,

The Grishas are a challenging bit of kit to go up against for the time the scenario is set in. Best advice is to avoid them entirely and stay outside the range of their sensors.

There's a map of the emitters included with the brief; you don't need to do anything special to get them to emit but you will need to get rather close and terrain could also block LoS under some conditions.

If you feel like something may be bugged or not working as intended please let me know via tech support (this subforum doesn't support upload of saves) and I'll look into it for you [:)]

Just playing this one now, and (doh!) I should have read this first. Those Grisha's are REALLY annoying. Easy to tell when they've found you because they follow your every turn like lost puppy dogs.

So, yes. I really need to stay out of their way.

I have a new strategy for this one. I'll let you know if it works. So far I'm good. We'll see. Haven't gotten to the meaty part yet

It worked. I was able to avoid those annoying patrol boats. Mission accomplished. No spoilers.

I'm in dire need of ideas here as I was planning to do an AAR of this scenario but could not get past those [:@][:@][:@] patrol boats (and sonobuoys, of course).

Might have to take the long route.

I can't seem to get passed this mission even though I collect all the data. Is there a way to manually advance the campaign?

You can load individual scenarios from the scenarios selection. And you need to collect data from 10 radars (i think), more than the POI's you've marked on the map, so for a general idea where they check the map provided in the briefing as it has marked most of the locations. Once you get all of them, you will get a passing score. Oh and make sure to have the latest version installed, as there was a bug before that made progression impossible.

I had issues getting data from the two sites close together in the east. Think there is a bug.

Check this AAR i put together. I mention the Grisha problem and my proposed solution.

This is quite frustrating, the Grishas detect the boat on creep at 22.6 nm with a 15 nm passive sonar. If I was running deep or if I was low they always get me bofore I detect them.

Very strong surface ducting, I assume? (Extends nominal range considerably, especially if the sea is calm). Active sonar so your creepiness doesn't matter?

What's your depth? You want to be inside the layer as much as possible when around hostiles.

Thanks for the hint. Realised that the layers begin below 70° so keep away from coast is counter productive.

Alternatively, if you're around hostiles and near the coast, you want to be on the sea floor, so that you blend with the sea floor noise.

IIRC we model the fact that nuclear-powered boats cannot hug the bottom (they need some clearance for the reactor cooling circulation loop).

These Grishas give me a hard time. Try to sneak around the the island, below 70° N to have a layer to creep inbetween but got instashot without getting awareness of the grisha that shoots on suspicion.

EDIT: But finally I've managed it, by Major Victory. I've learned this needs some micro maangement and patience.
