I'm not seeing the connection to the F-35. I guess you know there was a competition for the right to build the JSF. Both aircraft met all the requirements for the competition. So can you please clarify?

The F-35 continuously overruns budgets and gets more and more money poured into it. I think this is the what is being referred to.

[engi_nerd]

It has a history of overrunning budgets, yes, but the per-aircraft cost is declining and should continue to decline. I thought parent might have been referring to budget issues but I'm not really grasping how that's relevant.

The per-aircraft cost is still 3x or more that of the F/A-18, and the costs of operating it are also dramatically higher. http://breakingdefense.com/2014/09/gao-draft-slams-f-35-on-u...

http://www.bga-aeroweb.com/Defense/F-18-Super-Hornet.html F-18E/F: $65.3 million (flyaway cost) or $80.7 million incl. support costs. You'll see a number of places quoting slightly different per unit costs for an F-18E/F, but they cluster around that figure. The cost of an F-35 in the latest LRIP lot (8) was as follows:

http://www.janes.com/article/46129/pentagon-finalises-f-35-l... "The US buy is for 19 F-35A conventional take-off and landing aircraft at USD94.8 million apiece; 6 F-35B short take-off and landing aircraft for USD102 million each."

That does not include an F-135 engine for each jet, which is anywhere from $10 to $15 million depending on the variant.

So while the F-35 is more expensive than the F-18, I do not believe the figures bear your "3x or more" assertion.

Also it's difficult to compare the operating costs of a fully mature aircraft like the F-18 with the F-35, which is still being tested and developed. I don't think that is an apples/apples comparison.

Sorry, I was going off F/A-18D unit costs from Wikipedia rather than the Super Hornet. Still, ~2x the unit cost plus a 79% increase in support costs is nothing to sneeze at.

[engi_nerd]

Well keep in mind that we are still in a low production rate situation. Production will ramp up greatly in the next few years, driving costs down further.

While I think the JSF is quite the boondoggle, this is not necessariy a fair comparison. We should expect the F-35 to cost quite a bit more in both upfront and operating costs; it is, after all, much more capable.

[ceejayoz]

There seem to be a wide variety of concerns on the capability front.

I think somewhere else on HN today there was mention of the famous discussion between Kissinger and Ellsberg about how the world seems different when you have access to information that most people don't.

I think most people that work on the F-35 feel that way.
