Omicron Lambda at the Sinai Shipyard. There two tow ways to get there:
1. Omikron Alpha -> Unbekannt Alpha -> Omikron Beta 2 -> Omikron Lambda
2. Omikron Gamma -> Unbekannt Gamma -> Omikron Major -> Omikron Major 2 -> Omikron Lambda
This routes lead through pirate- and nomadsytems and are for this reason very dangerous. You'd rather get an escort because otherwise you probably won't make it.

The easier possibility is to buy them from a weapon dealer at Manhattan. Just ask in the universe chat. A cannon should cost 170k to 220k credits, a blaster shouldn't cost more than 250k credits, everything above is usury.
