After various questions on how naval positioning works, I decided to do some testing. Because this is a fairly ambitious project, I would like some help figuring this out, so I've chosen a simple and easy to reproduce test environment:
- HoI3 For the Motherland 3.05 (no mods)
- 1936 Scenario as Brazil.
- Change commander to Moraes Rego of Brazil's "Marinha Do Brasil". Send fleet to Blanca Bay. Wait for it to arrive.
- Edit save game file to reduce Argentina's neutrality to 0
- Play as Argentina on the saved game and DOW Brazil
- Combine Argentina's "Armada de Argentina" to be all 10 naval ships except the submarine. Change commander to Storni. Send fleet into Blanca Bay. Save for at this point for easy future re-testing.
The results so far are quite interesting. I've tracked just two of Argentina's ships for simplicity over five trials. The fleet loss column is where I simply totaled the total percentage strength loss of all the ships in Argentina's fleet:
A few things are obviously apparent from this:
- Positioning has no impact on attack or defense, nor any impact on guns' effective distance.
- Ships that recieve individual modifiers recieve them consistently based on technology as an addition to the base fleet positioning.
- Positioning scores are remarkably consistent when all things are equal.
- Fleet losses are directly related to positioning. More research needed.
[**] When positioning is the same, the fleet losses will be identical.
That last point was quite a surprise. Three out of five times the fleet had the same positioning (the 57.8% positioning score), and in all three times the exact same ships took the exact same losses. I was not expecting those results at all!
