You can build fleets by producing ships at your bases shipyards, or by splinting a existing fleet
There is no limit to how many fleets you can have, but you are limited to how many astros you can have fleets over.
The limit is your number of bases * 2 + number of occupied bases + computer tech level
You can move your ships with extra speed by selecting a available space gate or gateship
You can use other alliances space gates if they set it to public, but it might cost a percentage of your fleet size
If you add a cloak ship, each cloak will affected the detectable size by -5%, limited to -25%
holo ship does the opposite, +5% up to +25%
To move a fleet, you have 2 choices
* The first option is available to Premium account only.
To move part of a fleet, you need to split it.
First you click on your desired fleet that have the ships you want to move.
On the fleet page, you will notice several tabs, click on Split.
You need to type the new fleet name, as by splitting you will divide your fleet in two.
Type the numbers next to each ship type you want, if you have 100 corvettes and want to move 10, inform the number.
The block on the right side will calculate how much marine and hangar space you will have on your new fleet, so you can split with those types to send it to where you want.
Are you done? Click the button 
The game have cloaking tech, which allow you to build Cloak Ship, Holo Ship and Cloak Generator
The 2 ships works reducing or increasing its fleet size to the other players scanners, at 5% per ship, 50% maximum.
So if you have a fleet size 10,000 and 1 cloak ship, it will appear as 9,500, causing the enemies scanners to detect it later than it should at normal size (9500 seconds befor landing, not 10k)
And if you wish to scare them with a fleet size 7.5m, instead the real size 5m, add 5 Holo Ships 
The Cloak Generator is a defense structure for your bases, it works similar to the Cloak Ship, by reducing its detection. The scanners will only list your base at their screens if their Stellar Cartography Tech is at least equal level of your Cloaking Tech.
At a Fleet Overview page, there is a combobox with all your fleets
When you click it, it will open the list with the following colors:
fleet on route
moved under 10 minutes ago
moved under 1 hour ago
moved under 1 day ago
moved under 1 week ago
the list is ordered by on route, user order, fleet name
The Ships Market is where you can buy ships
The daily limit that you can buy is related limited to your bases production capacity for 24 hours, except the speed universe where the limit is doubled (48 hours)
The daily limit also increase by your account total experience, in the percentage to the game universe top xp player. The top player will have 100% extra limit, and you will have it proportionally to him/her.
Its up to you to get that 100%!!
The ships prices are related to your account level, 75% + level, so if your level is 10, you will buy the ship original cost +85%.
At level 100, it will cost you +175% (example for a fighter, 5+175% = 13.75 rounded up to 14 credits)
