In other words, if you equip Fletcher-class destroyers with Mark 9 depth charges starting from March 1st, 1943, and then you run a mission with a little fleet of them taking place on the same date, it is possible that only a small number of vessels, or none at all, will have those DC's aboard. As in real life, it takes some time for upgrades to be fully adopted. If you change mission's date to mid March, you will see that an higher percent of destroyers will have the new DC model. I have not exact figures, but probably the game will require a few weeks, or maybe 2-3 months, for a new equipment to have a 100% chance of having been actually implemented

Sonds very good and realistic!
