IJN Hiyodori *Done*

What about Sub Hunter and ASW Pinpointer?

I came up with this combo while thinking about HMS Hotspur. But I think maybe it would fit better here?

ASW Team (or some name like that) - During your Surface Attack step, if another friendly unit has made an ASW attack against an enemy Submarine, this unit can roll one extra attack die when making ASW attacks against that enemy Submarine this turn.

This would trigger if the target had been attacked by an aircraft or a ship. 

Combining that with Sub Hunter would make it a pretty decent ASW unit IMO. You would know at the end of the Sea Movement step if you could set up the SA by putting an ASW aircraft in the sector in the Air Placement step. That gives a player at least some chance of creating and triggering the SA IMO.


Based on this:

ASW Swarm - During your Air Attack step, if another friendly aircraft makes an ASW attack against an enemy Submarine, this unit rolls one extra attack die when making ASW attacks against that enemy Submarine this turn.

I apologize for the misunderstanding. I am all for repurposing an SA for a similar use mechanic. What I don't like is the exact same SA getting a different name.

In this case I am not aware (please correct me if I am wrong) of an SA that gives a +1 boost to a surface ship ASW attack if the target sub has already been attacked that turn.

Updated Stats
Speed 2 +Speed SA? 30k is fast
Hull 1 5 2
2x 4.7 = 3 2 2
AA 4 is fine
ASW4 is fine also

I'm actually surprised that no one is pushing for the Early Deployment or Coastal Deployment aspect of the unit. Imagine this unit:

Ship - Destroyer

1936
Speed: 2
MG: 3-3-2
AA: 4
ASW: 4
TT: 1-1-1-1
A/VA/HP: 1/6/2

Sub-Hunter - At the end of the second player's Sea Movement step, you may place this unit in an adjacent sector that contains an enemy Submarine

Early Deployment - This unit may deploy in any sector on your side of the map. you may deploy one Cruiser or Destroyer in this unit's sector. Each unit deployed this way can't claim an objective on turn 1 or 2

You now have a unit that can start anywhere on your side of the map (possibly harassing an infiltrating sub), with another cruiser/destroyer and a R3 torpedo attack on turn 1. This unit could possibly target an enemy ship on Turn 1 of the game and get all the Torpedo boosts that the IJN have. Actually kind of scary.
