Gosh, this is exciting. This is the first system that I've ever visited that isn't Sol!
Ha! Just wait until you meet your first xenos or run into a set of ruins.
I remember when I met my first Xeno scum, I name them the Klat something or the something Klat after their first ship design I ran into, the point being, they were a bunch of jerkish turds. It was an 6.43 version game.
I sent the 1st Armed Exploration fleet, comprimised of 1 jump beam frigate, 1 PD frigate and the other 2 missile frigates, to the last unexplored jump point of Sol. The newly discovered system was Alpha Centauri, a binary system with 8 planets, each with 2 to 5 moons. Just barely 20 seconds after arrival I detect a thermal signature over Alpha Centauri-B II, stronger than any of my ships and a EM even more strong.
I was like "Yes! Finally, aliens! That diplomacy team will actually be useful for something", so activate transponders, assign the team and initiate communications and I give the order to the fleet to go to the nearest planet, Alpha Centauri-B VIII. The fleet was going to take 5 days getting to the planet, plenty of time to establish communications, I thought it was going to be a peaceful encounter.
Oh boy was I wrong.
After a few minutes, the thermal contact turns into 4, and reads a speed of 12000 km/s, that was twice the speed of my ships, just a 1/3 shy of the speed of my long range missiles. After 2 in game days the contacts enter active sensor range, communications rolls have failed and take a look at the picture of the aliens, some strange being with tentacles in its mouth and a medallion around its neck.
I was excited at the time: "They are getting close for communications!", 12 hours later they are barely 50m km away, thats when something at the back of my head says: "Perhaps they are not coming close to chat more likely you intruded in one of their holy worlds or something and they want to turn you into space dust.".
I decided to not listen to the voices in my head and greet them xenos with open arms. At the 30m km range, the aliens launched a salvo of missiles, 40 missiles to be precise, and that was just the first salvo, they kept shooting more salvoes as they were getting closer. I quickly assigned weapons to the fire controls and assigned targets to my missile frigates and gave the order to launch a volley. The enemy projectiles were travelling at a speed of 30000 km/s, while my fire control had only 10000 km/s tracking speed. My own missiles were travelling at 18000 km/s and with a size of 5, I didn't had much of them.
As most can imagine, it went very badly for me. I was only able to destroy 8 missiles before my frigates were engulfed and destroyed. In the meantime, all my 30 missiles were destroyed.
After the destruction of my fleet, I felt naive, stupid and betrayed. I offer them a hand and they blew my ships. That forced a massive effort to build new ships, I checked the designs of other people, I read in detail how combat works. After an entire day in real life of preparation I was ready to send my ships. This time I sent 2 Retribution Fleets, each led by a cruiser, was composed of 4 missiles frigates with new missiles, 4 PD frigates, 2 beam destroyers and 2 colliers filled to the brim with missiles.
It felt so good destroying their petty little ships and blanketing their worlds, turns out there were of them behind a jump gate, in cleasing nuclear fire.
