The Thermal Ray Turret is a base energy weapon. It is the first base weapon and first base energy weapon available for research. They fire yellow pulses of lasers at targets with slight spread in bursts. They are common short range weapons for base defence that low level players use.
The Thermal ray turret is a powerful close range weapon, particularly at level V, able to fend off mid level fleet attacks at such ranges. They are relatively light and cheap in terms of resources. Because of its light mass, combat modules can equip heavier armor and shields.
Their lasers however can be dodged, most energy weapons do not miss - Thermal ray turret is an exception, they can miss their bursts firing at high speed targets with a small profile size at maximum range. Thermal ray turrets are easily out ranged by destroyers and are of minimal use when it comes to defending a base for long range attacks.
The Thermal ray turret was commonly used until blueprints were introduced, bringing in the much more powerful Tachyon beam turret to replace the Thermal ray turret. However, players who lack blueprints continue to use the Thermal ray turret.
The Thermal ray turret was once called the heavy beam laser.
