how it works - fort building

[vaned74]

I did some testing on fort building out of curiousity to determine cost/time to build various levels.

I set up 10 Japanese naval const battalions (36 Engineers, 3 engineer vehicles) on two islands - Etorofu & Ishigaki.

Ishigaki started at level 2 fort, Etorofu at lvl 0. Both are non-clear terrain. On both islands thus were 120,000 supplies and 510 engineer equivalents (360 squads, 30 vehicles).

Both islands built fairly consistently in pace, Etorofu took less time to reach level 9. Here are the results for level to level builds w/supply costs.

Level 0-3 - Etorofu reach level 3 and 8% to level four in 3 days at a cost of 1,000 supplies.

Based on both islands (variance of 3% faster build rate at Etorofu).

Build level 3 to level 4 - 510 eng equivalents build at rate 11.5% per day; cost 280 supplies or 24 per 1% progress
Level 4 to 5 - 8%/day; 290 supplies/day or 36 per 1%
Level 5 to 6 - 5.5%/day; 290 supplies/day or 52 per 1%
Level 6 to 7 - 4%/day; 800 supplies/day or 200 per 1%
Level 7 to 8 - 3.1%/day; 800 supplies/day or 267 tons per 1%
Level 8 to 9 - 2.7%.day; 800 supplies/day or 299 tons per 1%

Note, you cannot build above level 6 w/o 25,000 tons of supplies present at the base.

So, totals are:

Levels 1,2 and 3- cost about 1,000 supplies and take 3 days
Level 4 - 2,400 tons of supplies; 9 days
Level 5 - 3,600 supplies, 13 days
Level 6 - 5,200 supplies, 19 days
Level 7 - 20,000 supplies, 25 days
Level 8 - 26,700 supplies, 33 days
Level 9 - 29,900 supplies, 38 days

To go from level 0 to level 9 required ~93,000 supplies and ~145 days for the 10 battalions.

Obviously in bang for your buck - level 6 is the best payout and a large engineering force can achieve this in relatively short time.

I also tested 5 battalions building and the rates where just about exactly equal to 1/2 of the build rate with 10 battalions (510 engineer equivalents).
