High-G Airframe

 is a performance slot boost available to the Liberator and Galaxy. It is unlocked and upgrade using Certification Points.

While fitted, a high-G airframe improves the power of the aircraft's vertical thrusters, an increase to their maximum pitch and the rate at which they accelerate into a pitch. The effect of "increased agility" is unclear.

Each rank of High-G Airframe is 100% more effective than the last, with rank three providing three times the benefit of rank one.
