Shield Generators come in three sizes: small, medium, and large. The smaller the generator the more efficient it is at producing shield power, but the less output it has. Every generator is equally efficient to a generator of the same size, regardless of technological advancement, but more advanced generators have higher outputs.
Larger ships innately have more powerful shields. The larger the ship, the more overall output the shield system has and the more damage it can weather.
But the shield generator becomes less efficient as a ship becomes increasingly large. After 100kt, every extra ton is less efficient at producing shield power, and this effect compounds. Ships under 100kt are perfectly efficient. But a ship at 500kt is only 95% efficient. By the time any ship reaches 4 million tons its shields are only 50% efficient overall, so it is effectively paying double for each point of shield power compared to a much smaller ship. After 4.1M tons ships gain no more advantage to shield strength by becoming more massive, but do still have to pay the cost of the extra mass in generators.
As technology advances, new shield generators are introduced that have higher outputs. In a new technological generation, medium shields have the same output as a last-generation large shield, but retain the better efficiency ratio of their medium size.
The same rules for cost as other technologies apply, with prototype shields costing 25% more and mature shield technology costing 25% less.
