Has any factions or fleets ever dove into the research of Space Based Projectile Weapon's?

We have energy and missiles (photon torpedos)

Yes. Very recently. And in the past.

You need to check the R&D forum before you ask these silly questions. Then you'd know, and like GI Joe says, "Knowing is half the battle."

He dosen't say that having a bigger gun is the other half tho, asshole.

Anthos has a series of projectile-based weapons R&D'd.

That reminds me, I should go back to work on my latest Anthos RP.

It's nice to know that those have been researched on and are being used, was just curious thanks
