I'd like to add to the original topic. While many (esp. fyron) will argue with me there is no useless weapon in this game. Let me review some:

Torpedoe weapons - that tech tree is available early and starts off cheap but goes up to level 10. Initially same points put into DUC will give you a better result. Torpedoes are generally useless untill Quantum. Then the weapon becomes quite the useful. True, it doesnt have the best dkt ratios and ROF 2 but its one of only three heavy-duty weapons. It has an advantage over WMG for coming earlier, IIRC being easier to research and having lower ROF and tonnage. Those things, when put on large or better - massive - mounts they can down ships with few shots. Those weapons are also the ultimate long-range because they lose no damage. In my tests a LC with torpedoes and shield depleter beats a LC and sometimes a CR armed with PPM and NSP. Overall it provides a relatively unique strategies that can give great benefits in the long run. Never a short-term weapon.

Graviton Hellbore - tell me what you want about how weak and useless it is, two salvos done in short range and your all-powerful APB killer-ship is toast. ROF of 2. This one is ultimate melee weapon, but especially fefective at WP defense - you get to fire and move first, and you're up close already. Just set appropriate strategy, back it up with some lower ROF weapon and it'll take some effort to breach those WP's. Besides researching Astrophysics 2 gives some other benefits, and GH is cheap to research or build.

Anything more?
