Yes, the F135 was much more mature than the F136. But the price of the F135 jumped after the F136 was killed. You also run the risk of grounding the entire fleet when a systematic engine issue occurs.
Not as big of deal if you have a competing airframe, such as F-15 vs F-16, or F-22 vs F-15. When you are guaranteed to get all future sales, prices tend to go way up.
The real problem is development costs are out of control, and have been for a very long time, so you can't afford to develop multiple airframes and engines any more. Some of this because of more complexity, tougher requirements, more optimization, but a lot of it, IMHO, is due to changes in processes and cultures.
Competing airframes = $$$$$
Specialized airframes = $$$$$
Rehash of existing airframes - Wasteful and pointless.
Every new airplane is always going to be worse than "That other plane"
"Instead of A-10's they should have gone with A-7's!!"
"Instead of the F-16's, the world missed out on F-20"
"Instead of the F-22, they should have gone with the YF-23!!!"
"Every cancelled program should have never been cancelled because "reasons"
Now with the F-35, it's the X-32 or they should have built more A-10's or X,Y,Z
I won't even get into Hornet and Superhornet vs A6\A7 and F-14s
Which variant saw the increase ( *-100 or *-600) and what is the year by year unit cost with the jump? Early in the program, before they Dod brought out thors hammer in 2012 they had the whole crap with supplier costs but from what recall they had kept prices fairly stable over the years. You have the actual numbers?
I don't think that the P&W isn't purposely out their to fuck over the taxpayer and several airforces around the world. The F135 (sans afterburner) is powering the B2 replacement and the Pentagon remembers fuckery next time contracts are out
I'm also looking forward to what GE and P&W do this year with the adaptive engine demonstrators that have been flying since last year and if rumor are true the F22 replacement is already flying.
The B3 and NGAD or whatever is allegedly leveraging a lot of the work done on the F35 program and done in record time so in the grand scheme of things this all hopefully resulted in a lot of money well spent.
This stuff is going to be flying for the next 50+ years
Meanwhile, while everyone is picking their favorite aircraft, the military has to focus on "mission" and what the mission will be.
We live in era where politicians just love blowing up armed civilians in pickup trucks in other countries where don't have to worry about air defense systems or any significant threat to aircraft. That "mission" doesn't require jets. We could literally just rent Super Tucanos and drones.
I will come out and say that I'd rather we keep looking forward than looking back and I think the F-35 is good plane that's going to serve a lot of countries well. I think they will bring operating costs down over time, especially when it comes to the coatings which is big part of that cost.
I'm in the camp that we should be building things like 6th gen platform and F-35's and B3's. I don't even care about arguing on their value or purpose anymore because I'm confident that time will prove me right.
I came into this thread with the intent of discussing\debating the F-35 like the original thread back in OT from years ago.
Your points actually led me to catching up on all the fun little congressional reports and poking around. Good stuff. I do enjoy the discussion.
However
Nickqt's comment seems more important and worth talking about.
I think the more important question is what the fuck we are doing around the world where we are basically bombing and murdering around the world for vanity purposes and "Votes".
I don't think we need the size military that we have and I don't think we should be coming up with excuses to show the world that we have a lethal military. I do believe that we should maintain a modern capable military and that includes things like modern aircraft that can survive a modern battle field with a peer state.
Do I think we need bases all over the world?
No.
Do I think we need multiple carrier groups in every patch of ocean?
No.
Do I think we should be worlds leading arms dealer?
Gotta think about that one.
