New technologies should make iteration time on this stuff faster not shorter... even for complex things like fighter aircraft.
The fact that there are over a dozen Chinese humanoid robotics companies that have shipped working products in the past 12 months should be a big red flag.
I will say though that during WW2 and the Cold War, the amount of tolerance for killing test pilots was much greater given the number of people dying during active military conflicts at the time.
- DoD / DoW is a chaotic project owner, trying to squeeze in colossal and sometimes self-contradictory lists of requirements, which it wants to change often.
- The US government is a poor customer, which runs out of money from time to time.
- The US Congress is a cantankerous financier, which haggles for the money every year, and demands the production to be distributed all over the place, to bring jobs to the constituencies which voted for the congresspersons.
- The companies that produce this stuff are few and mostly cannot be easily replaced, and they know it. This is because in the late 1980s the US government decided that it has won the Cold War and will not need the many competing manufacturers of military gear any more. That proved to be a bit shortsighted, but now it's a bit late.
I think that mostly means money is cheap in China. In America, if you try to start a humanoid robot company you'll immediately run into the "Why though?" question when you try to get money for it. The case for the economic relevance of humanoid robots is dubious at best, so to proceed with such a development program you need your own money or at least good friends with connections who don't care about money.
Just the software for the helmet alone provides a huge technical advantage that has little to do with how the aircraft is manufactured other than having the appropriate sensors, communication systems, and computing power. Yet through all that bureaucracy what would normally be 3 different airframes all get to leverage the same systems without the need for retrofits etc. It’s inherently a two step process to figure out what you need before you can finalize the design.
By comparison vs the F-35, the B-2 spirit was vastly more expensive and far more limited. The F-35 also costs less than the more specialized F-22, but that versatility takes time.
That said, we could have made more than 195 of the them, but even at 750 it would have still been significantly more expensive per aircraft than the F-35 and it wouldn’t have let us cancel the F-35 program.
It would cost an insane amount of money.... but... It already does cost an insane amount of money, and then we have to run three separate military aviation programs for different regimes.
As to cost, in many ways a cruise ship is a better comparison than a cargo ship. The giant crew needed to maintain and operate a large aircraft fleet themselves need support staff, supplies, housing, etc. Carriers are expensive because of the people and systems onboard not the size of the ship.
Even just moving aircraft up and down from the flight deck requires a massive and thus expensive system. Civilian nuclear reactor are hideously expensive to build and operate let alone a system designed to ramp up and down more quickly, operate on a moving ship etc. Close in weapon systems have limited field of fire when you want a clear flight deck etc.
So sure, in theory you could just say we want a larger flight deck and are going to just have a number of empty components to pad out the ship but it’s not so simple.
Now that we do have the Third Locks, I think it would be reasonable to replace the bridges and make the alterations, a rounding error in the CVN budget.
The much smaller Wasp-class amphibious assault ship on the other hand can carry as many as 20 F-35B’s. https://en.wikipedia.org/wiki/Wasp-class_amphibious_assault_...

Design iteration cycle-times should be decreasing due to CAD, experimental cycles-times reduced due to the proliferation of rapid-turn 5-axis CNC mills, experimental cycles reduced due to simulation, business processes streamlined due to advancements in JIT manufacturing and six-sigma/kaizen/etc, and so on and so forth. That this isn't occurring is a giant blinking red light that something is wrong, and that we are going to get our lunch eaten by someone who researches, designs, and manufactures with a modicum of competence. Ostensibly China.
