Naval blockade

Hey guys/girls,

First time posting on the forums, thus first time submitting my house rules, so bear with me. I created a stylized rule sheet, but as far as I understand I’m not allowed to post a hyperlink yet, so I will have to type them out here. I apologize for the lack of aesthetic.  :-P

It is important to remember that I have no idea if these rules are balanced or not. I have only had a couple of chances to test it out. That’s why I would love some feedback; any observations, improvements, and criticisms are encouraged and welcomed. Don’t hold back, folks.

HBG provides beautiful blue acrylic naval mine tokens that I use when implementing these rules. In essence, my naval mines act as ocean AAAs and the similarities can be easily discerned. This also helps in understanding their affect.

Naval Mines
Cost: 6 IPCs
Attack: N/A
Defense: 1
Movement: N/A

Unit Characteristics

Blocks Enemy Movement: Sea zones containing naval mines block the movement of enemy sea units. However, cruisers may bypass naval mines, as well as disarm them.

Sea Defence: A naval mine unit can defend only when enemy units enter the sea zone containing the naval mine. Naval mines defend only once, before the first round of combat. Naval mines may defend up to three times, but only once per attacking sea unit. For each “1” rolled, the attacker chooses one sea unit as a casualty. These casualties are removed immediately, and will not participate in the remainder of the battle.

Amphibious Assault Defence: In the event of an amphibious assault on a coastal territory with naval mines in the adjacent sea zone, transports must be chosen as casualties first. A die is rolled by the defender for each transport engaging in the amphibious assault, up to three times. For each “1” rolled, the attack chooses one transport as a casualty.

Limited Placement: Naval mines can only be placed in sea zones adjacent to coastal territories.

Cannot Hit Air Units: When defending, naval mines cannot hit air units.

When a coastal territory is captured by enemy land units, any naval mines in adjacent sea zones are destroyed.

The transports taken as casualties first may seem, “iffy” (for lack of a better term) but it is meant to emulate the real danger posed by naval mines. I am worried this might be imbalanced/overpowered, but I think it adds a whole new dimension to Amphibious Assaults.  
In addition to the Naval Mines, I sought to expand the role of cruisers. I think the general opinion is that Cruisers aren’t worth their cost (though I could be mistaken.) With this in mind, I decided to provide a specific foil for the Naval Mines, but merging the role of a Minesweeper/hunter with that of the Cruiser.

Cruiser/Minesweeper
Cost: 12 IPCs
Attack: 3
Defense: 3
Movement: 2

Unit Characteristics

Minesweeper: Cruisers are specially equipped for mine sweeping duties. When entering a sea zone containing naval mines, cruisers cancel the Sea Defence and Amphibious Assault Defense characteristics of the naval mine.

Minehunter: Cruisers can also attempt to disarm naval mines. After combat (if any) is resolved, cruisers can attempt to disarm any naval mines present. If a “4” or less is rolled, the naval mines are disarmed and removed from play. If a “5” or more was rolled, the naval mines were not disarmed, and the cruiser must wait until the next round to attempt to disarm them again.

Treat hostile Naval Mines as Friendly: Cruisers can move through a sea zone containing enemy mines. Their movement is not blocked by the Naval mines.

Any and all comments are appreciated. If you notice anything even just by reading these, share it. I’m also open for rule clarifications, in case there’s any confusion.

Thanks guys/girls.

I agree this should be addressed. On the custom map we use all islands are worth at least 1 IPC, which helps somewhat, but like you said, it’s only financial.

I like the supply concept you have. Instead of tampering with all the unit stats, perhaps you could say that no surface attacks can be launched unless a friendly land zone is located in an adjacent sea zone. (double that distance with a naval base)

@the_jetset:

Retreating fleets disperse and then regroup again once safe.

Not necessarily.  “Disperse then regroup” is a tactic that was used – and only as a desparate last resort – by convoys of merchant vessels under heavy enemy attack.  I’m not aware of warship fleets using this technique extensively in WWII; some naval tacticians like Wayne Hughes have argued that warships are actually in a much better position when they’re concentrated than when they’re dispersed.

The Japanese fleet at Midway didn’t disperse as a result of its defeat because it was already dispersed when the operation started.  In his book Miracle at Midway, Gordon Prange faulted Yamamoto for his dispositions in the Midway operation: the Japanese fleet was broken up into several widely-separted forces, none of which was close enough to the other to provide any meaningful assistance to each other.  This dispersion wasted the enormous numerical superiority that the Japanese had over the Americans.  In fairness, the Japanese Navy as a whole (and not just Yamamoto) had a fondness for elaborate operations involving multiple fleets; their operation at Leyte Gulf in 1944 was another example.

@Tamer:

I like your original idea, but what about carriers?  They were the most important ships to keep afloat during the war, and a great deal of repair was done for them as well.

I do not recall any instance off-hand during the war in which a carrier was re-floated after having been sunk and then returned to active service.

The Amagi and Graf Zeppelin were both sunk and re-floated, but neither saw active service during the war and Graf Zeppelin wasn’t even complete.

The re-floating idea is kind of cool, but it may need to be reduced somehow to make it a more rare occurrence. As Marc said, it was a long and expensive process and not every ship that was sunk qualified for such a salvage operation. Unfortunately with A&A, we do not have the granularity in gameplay to determine how badly ships are damaged.

I suppose that you could modify the rule so that after combat you need to roll for each ship lost to determine IF it can be salvaged. Say you need a 2 or less to float a given ship. If you roll that, then you can decide to pay half to re-float.

It complicates things, but definitely makes it so you can’t just regenerate 2 battleships and 3 cruisers if you want.

I will offer another limitation that sounds logical to me, but you can consider:

Ships may only be raised on the following turn and to do so, there may not be any hostile warships in the sea zone where the ships were sunk. This implies that any ships not raised the following turn will be lost forever, as you said, and that the territory with your naval base cannot be taken by the enemy in that time.

Example:    Gibraltar is amphib assaulted by Italy. All UK warships are destroyed. Italy has no warships present in sea zone, only transports. Italy takes Gibraltar. US player lands and liberates Gibraltar on their turn, returning it to UK control. The UK player cannot then re-float ships lost in previous turn combat with Italy because they did not retain full control of Gibraltar.

Somewhat complicated perhaps, but I think some of these limitations need to be placed, otherwise I see this as being a huge advantage for the Axis. Germany and Italy in particular, because they tend to hole up their navies in home water areas and can potentially get double the naval power at half the cost. It will further incentivize them to stock up and stay in port knowing they can effectively respawn capital ships on the cheap. An element of chance and tactical consideration should be added so that it isn’t just automatic.

Yeah exactly. Another huge problem I have with this game is as said in the other forms, that units should have different attacks and defense against certain units. Transport craft in WWII have basic defense abilities against aircraft and fast attack craft so I still argue that it should have a defense of 1 for the sake of logic in this game.

I like it. Simple and effective.

What if Naval Bases could provide AA cover for ships in a sea zone serviced by a NB. It would seem logical, since the base is located near the coast and would most likely be equipped with Anti Aircraft weapons. So the rule would go something like this: Naval Bases could conduct an opening fire defensive action using an AA gun that could target no more than 3 air units, this would last only one round. After the AA gun fires, normal combat proceeds.

Though if the NB being used is damaged, it cannot use this ability.

Also, damaged battleships shouldn’t be repaired until the start of the owner’s next turn.  It’s stupid that Brition can damage it, America can damage it and Russia can damage it all in the same round and it doesn’t sink when normally 2 hits kills it.
