Here are the four possible paths I see us taking. They are in my order of preference.
Give Natalie at Kasgyre a Comm Officer. Also have it transport a Comm Officer to one of the Natalies currently at Glowcove if that's possible.
Anguis II, Viperidae, and 4 Natalies attack the Wreth fleet at Blackstone. One Natalie Scouting, the rest using Coordinated Fire. Use the Spire Guns for covering fire.
Ocker loads up Topaz Vanguard, Topaz Lance, and 3-4 Kettleguns. Smuggles them to Blackstone with Improved Blockade Running. Sets them up as spire guns.
All spire guns use Coordinated Fire.
Jupiter, Dionysus, and escort Natalie return to Glowcove. All Scouting.
All marines at Burned Mountain advance with Survival Tactics.
With all our ships and significant spire gun assistance, I can see us pulling off a victory, or at least causing a lot of damage to the Wreth fleet and delaying the capture of Blackstone.
Return Viperidae, Anguis II, and all Natalies from Glowcove to Kasgyre.
Strip 1 Comm Officer, 1 Silk Ream, and 1 Small Lift from Ocker.
Strip 1 Silk Ream, 1 Lance Cannon, and 1 Kettlegun from Viperidae.
Strip 2 Silk Reams, 1 Topaz Kettlegun, and 1 Kettlegun from Anguis II.
Equip Viperidae with 1 Topaz Lance, and 1 Topaz Kettlegun.
Equip Anguis II with 1 Lance Cannon, and 1 Kettlegun.
Equip Anguis with:
Topaz Medium Core.
Small Lift.
2 Topaz Trim Webs.
8 Trim Webs.
1 Topaz Vanguard.
8 Kettleguns.
4 Silk Reams.
1 Comm Officer.
Equip 2 Natalies with Comms Officers.
Also repaint all ships and upgrade the lance cannon cooling.
Jupiter, Dionysus, and escort Natalie return to Glowcove. All Scouting.
All marines at Burned Mountain advance with Survival Tactics.
Anguis II isn't that bad of a viper. It's miles better than Causinae was.
All our vipers have slightly lower silk reserves.
But our entire combat fleet is distributed with comm officers, camouflage, our lance cannons have their cooling upgraded, and the cannon loadouts of our vipers are rebalanced.
Strongest possible combat fleet for the next couple turns before we finish the docks.
Give Natalie XIV a Comm Officer and send her to Hive.
Viperidae, Anguis II, all Natalies use Coordinated Fire.
Load up Ocker with (Cannons, Marines, whatever we decide) and have her transport them to Blackstone with Enhanced Blockade Running.
Jupiter, Dionysus, and escort Natalie return to Glowcove. All Scouting.
All marines at Burned Mountain advance with Survival Tactics.
Consists of limited half-measures to save Blackstone.
Give Natalie XIV a Comm Officer and send her to Hive.
Viperidae, Anguis II, all Natalies use Coordinated Fire.
Jupiter, Dionysus, and escort Natalie return to Glowcove. All Scouting.
