Reason for urls protocol relative is useful for assisting pooling as its quicker and less resource intensive, ie, no need to renegotiating TLS security when an existing connection is available.
Wouldn't the biggest issue be the breeder reactor, so it isn't one but two reactors to keep going. One is bad enough, but a fast breeder reactor is likely to require far more skill and training for safe operation or operation at all. Any industrial machine or plant would be a serious undertaking at best to impossible to operate without training and documentation.
The cost for reactor design was done by the US Navy, hence that reactor design you talk about @Thucydides isn't optimal. Not sure if anyone else has birthed a reactor design that isn't a copy or based on the original US reactors.
Well the dynamics of the universe do not rule that all navigable space for combat is in vacuum that is devoid of matter. You may very well be in a nebula or even atmospherically dense gases in any number of scenarios, hell you could be flying your submarine in a gas giant, deep diving for safety.
Furthermore to that, I would construct my fighters out of pure diamond. It is extremely tough, and would also be an excellent beyond anything else to sink the energy received from energy weapons. Just like a heat sink, you can then just radiate the energy or use the energy for work, as in charging a weapon via whatever heatcycle you want..
Just thinking would you not want your dog fighter to be painted mostly black or whatever the prevailing wallpaper present in your corner space. But the paint essentially be entirely transparent to energy weapons and be a mirror finish underneath.
