Our luck is... Looks like The mighty RNG doesn't want to let us create an army.
Anyway, I propose: (in an order of importance)
1) Leave the moonies alone, stop
any communications. Let's look how isolationist they really are
2) Rebuild the weapon testing facility
3) Research the self repairing thing
4) Build a shield for The Avian Contact center, just in case. It will help against predators
\disasters\attacks. Also, transfer some combat drones here.
5) Build an airship, capable of hosting 50 colonists on a permanent basis, for the second mobile Avian contact center. Mobile center can communicate with all Avians, not small portion of them
6) Build minor orbital defenses around Planet B, and let's name it Infrenium
7) Design a new kind of military ship - slinger. Based on the fighters. All ship is basically a set of several engines, power, speed and agility is all it need, no weapons, basic armor, no shield. It can be used in 4 roles: a)tow damaged ships\containers; b) Attachable engine boosters for big ships; c) to move asteroid away; d) they may be used to launch projective (any, from tiny rocks to mines to torpedos to epically big spears to asteroids) just move close to the target, detach projective, turn around and let inertia to do the job. Note that they useful both in civilian and military roles. Build a prototype
Let's return to terraforming Aries, I propose to introduce some stored earthworms into the soil. Choose the smallest ones and the most adapted to cold conditions.
9) Use our transport fleet to get rid from the algae infestation, mechanically gather the algae, transport it to Aries, dump it in one place on dry land, and then let it rot, providing food to the earthworms. In fact we may gather even native organic materials from Gaia and Aquarius, kill, sterilize it properly and let it rot on Aries, but getting rid of the algae is preferable. Let's create one area with rich soil, then we may think about grass.
10) Design and build farm ships, basically big, mobile, transparent, space based hydroponic farms. We should move majority of our food production in space, in that way farming will never mess with ecology and, more importantly, ecology will not mess with the farms. Also wastes from farming may be used for dumping on Aries
11)Build two cloning centers for the settlements on Gaia
12) Build small scientific outposts all over Aries to monitor ecology more closely (like 20 with 10-50 scientist each)
13) Extensively explore Planet E, maybe we miss something interesting
BTW about the moons... are there any notable (more then 100km in diameter) moons around planets other then gas giant?
I like how we have our population in different places, it's hard to wipe us out in one strike, so we must develop all colonies, and maybe, create even more on B and E planets: military bases, scientific outposts, everything to lure people there. But it's more a long term goal.
