Excalibur - missile-armed heavy cruiser.
It was developed and widely used as a "flying fortress", with a serious numerical superiority, it can almost without loss be leveled with the surface of the planet enemy fleet.
To build this ship, you only need to learn the skill (production license) at the Orital Station.
Building Excalibur is available from the first level of spacecraft plant and does not require any special conditions.
Excaliber is the heaviest warship with a superiority in characteristics towards protection, which (no matter how paradoxical it may sound) makes it an excellent ship for a competent attack with minimal losses and excellent cover for a less protected fleet.
From the very launch of the game, this ship has been loved by the players and is still actively used, mainly, of course, for clearing important objects from frigates and fighters.
Due to its impressive characteristics, Excalibur does not differ in speed, but all ships are balanced among themselves, so you should not be disappointed, on the contrary, you can use it as protection and cover for other space ships, for example, Valkyries. Also, never forget class advantage mechanics in combat mechanics.
Excaliber vulnerable to Abaddon and Javeline, has an advantage when fighting Raptor and Hornet.
Best used in conjunction with profile modules "Shield Booster", "Bastion complex" и "Halo complex".
