>What is the scope of the improvements and refinements? The current F16 has very little in common with the original one that entered into service in 1978, even the air-frame was redesigned several times, new engine, new avionics new everything, the modern F16 blocks (C 50/52 onward) are like 6000 lbs heavier (naked) than the F16A naked while having a longer range and larger carrying capacity. >Computer? Automobile? Spacecraft? Telephone? Probably not. Dwelling or building? Potentially... Yes and no, in this analogy the F16 isn't a Laptop Model X123 but rather just a "Laptop", in the desktop PC world just a "case" and on top of that if the case could also be heavily modified. https://en.wikipedia.org/wiki/General_Dynamics_F-16_Fighting_Falcon_variants https://en.wikipedia.org/wiki/General_Dynamics_F-16_Fighting... And in space you can see it today take a look at Space X and the differences implemented in Falcon 9 during it's development from block to block. https://en.wikipedia.org/wiki/Falcon_9#Launcher_versions https://en.wikipedia.org/wiki/Falcon_9#Launcher_versions
