Cluster Missiles get kind of wonky on a Raider with Ordnance Tubes. First, the rules for bonus attacks:
Bonus Attacks
When an attack granted by a special weapon has the “Bonus Attack:”
header, a huge ship equipped with that upgrade may perform the listed bonus attack while it engages, before or after its standard attack. Additionally:
• A huge ship may perform any number of bonus attacks each round.
• A huge ship can use each “Bonus Attack:” header only once per round.
• If an effect grants a huge ship a bonus attack that is a primary attack or a special attack with an “Attack:” header, it can perform only one bonus attack using that primary attack or “Attack:” header per round.
That last bullet is the most important: an "Attack" header can only be used as a bonus attack once per round. Note that Ordnance Tubes requires you to fire missiles as bonus attacks. So you fire with Cluster Missiles, but it's already a bonus attack. This means you cannot spend a charge to make another (bonus) attack with Cluster Missiles.
You could put Cluster Missiles on your Raider without Ordnance Tubes, and fire them as your standard attack. The obvious downside is now you have no way to fire your sweet 4-dice primary weapon.
This also applies to the C-ROC equipped with Corsair Refit: you may spend 1 energy to perform a bonus attack with an equipped missile upgrade, but then you've already used your "one bonus attack limit" for that "Attack" header, so you can't make another attack with Cluster Missiles.
Maybe it's best just to leave the Cluster Missiles to the fighters and other standard ships in the game.
