However, I am not aware of any technologies that were based on SR and GR before the GPS system or nuclear weapons. Does anyone know of any earlier technologies?
If you consider nuclear weapons to be based on relativity (presumably because it turns some mass m into an energy mc^2), then by the same logic a campfire is also based on relativity. The mass m which is converted to energy is smaller, but the principle is the same.
