Fleet Capacity - increases limit of units that can be produced by 20 a tier, up to the cap of 125. Already at the beginning, unlock two tiers and develop this technology gradually, until the end of the game.

Production Cruiser - Refinery Mode - allows you to use Production Cruisers as resource collection point. Compulsory at the very beginning of the game.

Sandskimmer Raiding - increases max speed of Sandskimmers by 33%. It is a good idea to buy it, not necessarily at the very beginning of the game.

Sandskimmer Armor - each tier increases Sandskimmers' armor by 2.

Missile Ship - Direct Fire Barrage - speeds up cooldown rate of mortar attack (Direct Fire Barrage) that those ships are armed with, by 50% . If you have such vehicles, you can try out this upgrade. Still, this is not recommended if you are short of supplies.

Missile Ship - Radar Guided Missiles - improves accuracy of attack against aircraft. This one is a cheap upgrade and you can afford it.

Armored Unit Defenses - increases armor and, at higher tiers, health of Assault Ships and Missile Ships. If there are many Assault Ships in your army, this one is compulsory.

Assault Railgun - Dart Maneuver - provides you with an option to speed the movement speed of units. Not too useful for this type of units.

Honorguard Cruiser - Anti-Air - unlocks the ability to shoot down airborne units. However, it is necessary that you switch the unit into this mode and remain in it for the next 25 seconds. This upgrade is costly and inarguably, it is better to invest into additional Missile Ships.

Bomber - Ammo Capacity - increases bomb capacity of bombers from 2 to 4 per unit. The only situation in which you might not want to buy this upgrade is when you do not use this type of units.
