Interdiction

[DeepTyphoon]

Is naval and air interdiction destroying production points from the enemies stockpile? In the picture below for example, has the Japanese player lost 40 production points from his stockpile as a result of this submarine's supply interdiction?

Supply interdiction only destroys supply (the supply stockpile in that port), never production points.

However, strategic bombardement is supposed to destroy both production capacity (reduces the factory) and some from stockpile.

Okay.

In the picture below Truk has 140 of 140 "port supply." "Port supply" is "Production Points" in that port, yes? And this "Port Supply" is used to repair ships, planes and army, yeah?

If that's right, then in effect Supply Interdiction damage is destroying the enemy stockpile because thet port supply must be replaced, yes?

Supply is separate from production (it is not production point; they are two very separate things). Supply is infinite in a way (it does not show in the production screen). So if you have a direct land link and good rail line, a unit will get supply.

If the supply however must come by sea, then there are port limitations depending on size (portx20). So a size 7 port can supply units (land and air) that require up to 140 points. If you look on a unit info, it will show how much supply it uses. I can not remember for sure, but a full size corps requires something around 30 supply. So Truk could probably supply 4 of them (and probably an air unit too). Of course, in that particular case, it is irrelevant as there is no space for that many units on a one hex island (but it becomes very important for inland units that must trace supply to a, or more, port). Unit in excess of available supply points are in basic supply only (more or less bad).

So supply interdiction will reduce available supply from that port and possibly put some units in basic supply. Units in basic supply will not be able to repair. In other words, they will not be able to use productions points (which is another "pool", this one finite) for repair. But supply interdiction will never destroy production, just some points of the infinite supply stream (all ports, if left alone will get their max supply, which probably amounts to quite a lot of supply points (in the thousands each turn I would guess).

PS: However, it is possible to "raid" convoy lanes (those drawn on map on the sea). Those raids can indeed destroy production points indirectly by destroying ressources that will not then have a chance converted to production points. But the only way to destroy production points from the pool is strategic bombing.

Thank you.
