Our current western industrial society tends to build cheap disposable tech, specifically because our rate of tech progress makes things obsolete by the time they would typically need repair. In a society more like the Third Imperium, where both societies and general tech levels are stable on the scale of many centuries, you might see more emphasis being put on rugged, maintainable equipment. Brin touches on this in his Uplift series.

I thought quite a few times about what happens to older TL equipment in Traveller. Obsolete may have a different meaning on different worlds.

Also, its a myth that tinkering with old technology can produce a better capability. In general, a design would cost up to 200% to go through a redesign that changed its use requirement even 10%. This option is the least viable, and usually the last option taken when nothing else is available.

ObTrav: Aggressor forces are surprised by a spirited defense lead by supposedly obsolete vehicles from a military grave yard that has been raided for a couple of generations by the descendants of a lost Planetary Army that have tinkered them into superior performance. Think 'muscle cars with teeth' and yes they do maneuver exercises with them and shooting competitions.

Now here's something from the 'Defense Industry Daily' n/l that almost sounds impossible!

"Pratt and Whitney has maintained that they can develop a TF33 upgrade package that will keep Boeing's B-52 bomber flying until the 2040s. The eight engine bomber has kept the same TF33 engine since its induction in 1952, but high fuel consumption had the USAF looking at potential re-engine options. With oil prices dropping dramatically, the program was dropped; but P&W are still looking at improvements for the TF33 that will keep it on-wing, and allow the air force to reduce their maintenance costs."

These planes have been in service so long ('H" models were built about '60-'64) that the authors seem unaware that only the 'H" models had the TF33 turbofan. Earlier models had turbojets. The 'fanjets' gave the 'H' a much greater range than the earlier versions & were more powerful.
Still, I find it amazing that those planes could still be flying past the age of 75 years old!
