Hi, advice please.

Say its my turn to move and I wish to drop a bomb, what happens if a ship is already occupying the space the bomb would be dropped.

Does this mean I can't drop it?

cheers

Drop and it goes Boum! At the resolution time

Hi, Thanks for the reply, But I'm talking about can I put the bomb token down due to a ship being in that spot.

Placement of the ship would be marked, remove the ship, place the bomb, place the ship back down.

Cheers. Exactly what I wanted to hear.

Adding to what's above...

You can definitely place a bomb or mine so it overlaps another ship; as stated above, you mark the ship(s) that would be in the way, remove them, place the bomb token, then replace the ships. That's not always necessary, though, especially in casual games: sometimes, it's easiest to just hold the bomb token in the approximate place and tell your opponent, "This will clearly trigger on ship X," them remove the bomb without ever FORMALLY placing it.

As for the bomb EXPLODING... well, that would depend on the bomb:

• Bombs that are normally placed as you reveal your maneuver dial (Seismic Charge, Thermal Detonators, Ion Bomb, Proton Bomb, Bomblets) are placed on the field, but do not detonate until the end of the activation phase.
• Mines that are placed via an action (Proximity Mine, Connor Net, Cluster Mines) detonate as soon as they are overlapping a ship's base. If one of these bomb tokens overlap more than one ship base at the same time, you choose which ship actually triggers it.

There are also some situations (such as both versions of Captain Nym) that can allow you to prevent a bomb from detonating, as well. That way, given the correct circumstances, you could conceivably overlap a friendly ship with a bomb token, without having that bomb/mine detonate. These situations are fairly rare, though.
