Battleship skills  •  Cruiser skills  •  Destroyer skills  •  Aircraft Carrier skills   •  Submarine skills

While a commander is re-training (specializing to a new tech-tree ship), his skills will not function on that ship. They will function on premium and special ships.
Further, while he earns Commander XP, he does not earn 5% Elite Commander XP .
