Zmodyfikowany pancernik dla Wenezueli - 22.06.2010

Dziś nieco zmodyfikowany projekt pancernika dla Wenezueli (patrz post z 28 maja). Poprawiłem ochronę poziomą i przeciwtorpedową, co odbyło się kosztem opancerzenia burt (góra i końce), zasięgu oraz zapasu amunicji. W efekcie odporność na trafienia pociskami artyleryjskimi i torpedami nieco wzrosła.
