Harmonic Chase Thruster

"Thrusters designed for closing long distances quickly. When equipped to an AXIS hull, the Harmonic Chase Thruster provides a Harmonic Agility bonus for added mobility in combat to the entire fleet."

General
The Harmonic Chase Thruster boosts the forward and rotation speeds of your ships, in addition to a Harmonic Agility buff to your fleet. It is limited to A.X.I.S. Hulls or better.

Advantages
Like the Xeno Armored Thruster, this thruster drastically increases your ships' effectiveness in combat, enabling them to open fire sooner and kite shorter-ranged enemies.

Its Harmonic Agility bonus compensates for some of the loss in strafe speed, while further enhancing your fleet's forward speed.

Disadvantages
Harmonic Chase Thrusters take up more mass than Xeno Armored Thrusters and do not provide an armor bonus, which is not desirable if you only plan to tank with the ship this thruster is equipped to, especially in base combat.
