Description
To generate the energy required for this type of shield, modular power plants are usually installed. The energy bubble projected around the object is capable of absorbing a significant amount of destructive, directed energy, ion pulses and radiations, and gravitational waves.

All research bonuses are shown by reference levels. The study price is in Science points (values, they grow with the level). It can be instantly sped up with Dark Matter.
Science price and calculator
How much science each level needs:
Calculator: time and instant speed-up
Enter your science and choose a level — we'll show how long the research takes and how much dark matter is needed to finish it instantly.
Formulas verified: time = science price ÷ your science per hour (but no less than price ÷ 5), divided by research speed. Instant completion is calculated by the dark matter for the remaining time. Overlock multiplies the science price (and thus the time and dark matter): each overlock level is pricier.
Overclock (honing)
After the maximum level, the research can be “honed” with star ore — this gives a super-bonus.
Heavy Shield · first reset 150 star ore
Each reset adds the bonus on top of the max level; the star-ore price grows with every reset.
