Problem that Trek has is that power for FTL and shields, weapons life support and sensors comes from one very big and very single point of failure prone warp reactor. No adequate backups. This is the kind of thinking in supertankers where if the main and only engine or engine pair goes, you have no propulsion. All USN destroyers have at least two engine rooms with two engines each for a total of four engines in the form of gas turbines driving two propellers to provide both more power and redundancy of propulsion so if the forward engine room drops out, the aft engine room can continue to drive the ship while power is supplied by three separate gas turbine generators, one in each engine room and a separate third generator in a generator room between the two side by side helo hangars and giving redundant power generation. In Trek, kill the one big warp reactor and all you have is fusion impulse power which is STL and very limited power for shields, weapons or sensors and life support. There really ought to be two main engine rooms with their own warp MAM reactors and emergency fusion reactors to supplement impulse power reactors. Heck, NASA shuttle had three engines driven by triple redundant auxillary power units, any one which provided enough power for safe launch, orbit and return. And one engine could fail and you still reach orbit in early stage of flight and later two engines could fail and you could still make it to orbit and failing that, NASA abort options would see the crew to safe parachuting into the ocean in extremis. And, if NASA had the will and the money, the Shuttle II would have had a larger cabin that could separate from the Shuttle proper and land safely on the water or the land. But they lacked both money and will to do that. Future Trek ships should always have two engine rooms while separable saucers should have backup internal or retractable warp engines with a least Warp 3 FLT speed since a saucer on impulse STL drive is essentially stationary. In the second pilot, " Where No Man Has Gone Before", such a backup fusion powered warp engine or small backup warp reactor could provide the real possibility of reaching the ore refinery when main power was lost. This would tie into statement that bases were now years away. Without such backup warp drive, bases would be centuries away and not mere years. The same could be said of lifeboats, as their very limited propulsion makes them stationary as well and they should have at least Warp 2 or 3 speeds with enough range to reach the nearest star system.
