Turn 1433.5.

 

K-503 fired two volleys of SS-N-9 missiles at the convoy.  Unfortunately for NATO, the missile's initial altitude of Low was just outside their detection range.  The missiles then go to VLow and cannot be picked up until they are 24 nm from Iroquois.  I am using 30 second turns until they are detected.

EDIT:  The detection range for the small missiles at VLow altitude would be 10% of the listed range for an Air Search radar (using smarter radars rule).  So, the range to detect the vampires is actually 14 nm.

Turn 1438.5.

 

The first 3 missile volley was successfully engaged by Iroquois' SM2MR SAMs.  An additional 2 missiles were taken down from the volley headed for Halifax.  Because of weapon danger space, Halifax will have to take care of the last one.  Spoiler Alert: the last missile was destroyed just outside 3 nm.

 

The light red circle around Iroquois is the minimum engagement range for the SM2MR (just in case).

K-503 will attempt to run, since trying to sneak up on NATO ships with a noisy sub is not a good idea.

Turn 1439.

 

Time to hunt a sub!  A reference point was plotted at the convergence of the missile volley bearings.  Since the volleys occurred within a minute of each other, tracing their paths backwards until they meet would make for a good location to start hunting.  The image below shows Blue side only, with bearing and range information displayed.

Turn 1515.

 

Blue has picked up a sonar contact from sonobuoy B034.  The other buoys picked up nothing.  I am not familiar with helicopter ASW operations, so I am going to wing this.  Next I will drop another buoy below the layer and see what happens.  Below shows Blue side only.

Turn 1533.

 

The original buoys lost contact so I figured the sub is moving away from them.  I dropped some more further to the North.  I got a cross bearing that needs to be checked out with the dipper.

 

I decided to label my sonar bearings with the time of contact since it matters for passive classification.

Turn 1536.

 

Buoy B036 has a base classification probability of 45% against a noisy target at 24 kts.  A roll of 42 means I know who it is.  You can run, but cannot hide.  Sorry, Charlie II.

 

*** Breaking News***  Just before I posted this, I checked the torpedo stats and it looks like all the torps available to Blue player have a max depth of Int V.  But, the Charlie has a max depth of Deep I (where it is right now).  Does this mean I can't attack him?  Can he attack from that depth without fear of retaliation?

Well, here is what I have so far.  The Charlie II is at Deep I depth, and nothing the blue player has can get him.  But, The sub has torpedoes with a max depth of Int V.  I am going to assume this means they cannot be fired at a depth below the weapon's max depth.  So, I think this means a standoff.  The sub is noisy and can be easily tracked given the three helos available to Blue side.  The sub can find the task force again, but cannot risk attacking it without coming up a level and getting a torp up the rear.  I am going to call this scenario a victory for Blue since they can now safely transit the area.
