Hello all,, just bought the game and have a quick question.

If I have a target lock on a ship and I don't spend it, can I do another action the following turn such as focus? Thus having a Focus and a Target lock when combat phase starts?

Yes to both questions. Target locks are not removed during the end phase.

Combining target lock and focus is very useful if not essential with missiles and torpedoes.

Yes that is exactly how it works.

Once locked on it stays until spent, wither as a reroll on an attack versus that target, or if you use it for ordnance, such as missiles or Torps..

Awesome,, thanks for the help!

Pro-tip: When you're using Target Lock and Focus together, you cut each die's chances of missing from their natural 1/2 to 1/8!

You may also remove a target lock from a ship by target locking another ship.
