how to get this weapon ?

The blueprint for the LASER SHIPS have to be found while exploring and returning back to home planet with STARDUST. @nextcolony just made a post explaining. https://partiko.app/nextcolony/explore-the-galaxy-earn-rewards?

we must continue exploration then ?

Yes yes YES 👍

LEGENDARY PLANETS, LASER SHIP BLUEPRINTS, and STARDUST!

you use certainly explorer II?
