I can't speak to all Navies of the world, but those that I follow in
the English speaking countries have spent a great deal of money
modularizing, standardizing components (like O-rings), and increasing
the reliability and unmaintained life of equipment. And not just
because maintenance costs money and requires (often expensive)
training.
While preventative and corrective maintenance skills will be important
for long duration missions, it is _vastly_ preferable that the damn
thing 'just work', because every time you open something up for
maintenance (whether preventative or corrective), you risk damaging
it. This can range from the simple (nicking an O-ring or bending a
pin) to the spectacular (dropping a 20 million dollar periscope onto
the pier).
Hmmm....
Seems that you know well the current Naval field, agree, (I remember your nick on s.m.n.) but the issue is that, quoting yourself, the current technology & engineering has left the times more comparable, making abstraction with hardware & communications, with Space *exploration* that is, the times from Columbus to early XIXth century, of ocean *exploration* Today a modern Destroyer or freighter can make a port call near everyhere and make repairs or wait the spares without problems, this was not an option for the wooden sailing ships of Columbus, Magellan and Cook's times, and this is true also for a manned mission to Mars. If a non-catastrophic, but not-compromising mishap happens somewhere between Earth and Mars, what to do ? and spacecraft can't turn back easily (Apollo 13 was obliged to do a Lunar circumnavigation) and obviously there's no safe havens in the deep space between Earth and Mars (and also between Earth and Moon, excluding the ISS) So, repairing and/or make-do with what still work must be the only viable option. This is the core of my thinking, and the true meaning of "Naval paradigm"
