This mod requires Vehicle Framework. It works for all VF vehicles as well as Seamoth / Prawn.
Introducing the pinnacle of submersible defense technology, the Ion Defense Capacitor: a single-use, charge-based module designed to provide your submarine with temporary invincibility. Once activated, this capacitor harnesses the raw power of ion energy to envelop your vessel in an impregnable energy shield, nullifying all forms of damage for a critical period of three seconds. While its defensive capabilities are unparalleled, they come at a significant cost, consuming a vast amount of your submarine's power reserves upon activation. Additionally, the intricate nature of its ion matrix requires an extensive cooldown period before it can be re-engaged. Ideal for explorers facing the most extreme threats in the darkest depths, the Ion Defense Capacitor is your emergency shield against the unforgiving forces of the deep.
