90 - 120 hours is the target MTBF for a jet engine? _mind blown_ glad I am not in aeronautics.

An engine for a military application has very different characteristics from that of a commercial passenger plane. The MTBF for the latter is in the 100k+ hours, with servicing usually performed around 10k.

UAVs are the future. They are more affordable, they can be stealther, they can be smaller, they can stay flying for longer, and they require less ground support. I can not believe the F-35 hasn't been completely cancelled yet. Every partner of the US doesn't really want these expensive beasts.

Not trying to justify the F-35, it's a cluster fuck, but manned aircraft will be around for a while. Unless the operator is local, the communication latency for UAVs makes them unsuitable for some types of combat missions.

For some types, not all of them.

Also, 'Unmanned' does not necessarily means "remote-controlled". They can be autonomous.

We are making progress: http://www.naval-technology.com/news/newsus-navys-x-47b-cond...

This is after carrier landings and takeoffs and formation flying with manned aircraft.

And all that developed at a fraction of what the F-35 program will spend on engines alone

Every air force in the world wants these expensive beasts, it's the entire identity of the service - TOP GUN knights of old jousting for supremacy. The command structure of most air forces comes from the fighter pilots, it's a common complaint in USAF that transport, which is maybe the most useful day to day function, is a career dead-end.

Nobody in the military will take seriously a "warrior" that runs a joystick on a RPV, and when these things gain more autonomy it's going to eliminate the necessity for whole ranks of command. So the Air Force will fight to the bitter end for these things, long after they are will be effective solely as air show entertainment.

I think the F-35 isn't real, that all the videos of it are CGI, and that all these reports are supposed to convince us that this money has been lost, all while the government is secretly using the entire F-35 budget to build a flock of flying drones, walking and talking robots, and rail guns for the next major war. I have to believe such contrivances to avoid thinking about how my tax dollars are wasted.

The X-47B is pretty damn cool, makes one wonder with the rate of advancement they had why we would need to develop manned craft much longer. http://en.wikipedia.org/wiki/Northrop_Grumman_X-47B

The US Navy has said the F-35 is probably that last manned fighter for them. The X-47B is done after the refuel testing so it makes one wonder what is the next test aircraft.

I have my picture taken next to an F-35 thanks to a friend who is an F-35 pilot. I can assure you that it's fake. Most likely made of paper mache. The helmet's pretty cool though.

Make them semi-autonomous. For the amount of money spent on the F35, surely we can make the UAV's smarter.

I was thinking mostly about air-to-air combat. Other missions (recon, bombing, ground support, refueling, etc.) can or are done with UAVs now. But on thinking about it further, the UAVs of tomorrow can be much faster and more maneuverable than any manned fighter aircraft once you remove the requirement of keeping the pilot alive. I don't know that it could be done today, but I imagine in the not-to-distant future we'll have effective air-to-air UAVs.

Autonomous military drones seem politically unlikely. At least, I hope so, what a nightmare.

Procurement is often not about warfighting but about politics. That's why they split construction up among multiple locations -- that's multiple congressmen who have a vested incentive in seeing that money continue to roll into their district and provide jobs.

It's basically "New Deal"-type spending that is acceptable to the right wing (which, for the most part these days, includes the Democrats). The economy is in shambles, so you have to do something about it. But fixing the economy would involve breaking from your orthodoxy and upsetting your wealthy sponsors. So what do you do? Pay the unemployed to build killing machines, everyone loves those.

It's easy to blame the wealthy sponsors, but some blame also rests on the people who are convinced that literally all of the taxes they pay on their 250%-of-poverty-line income go to support those on 150%-of-poverty-line assistance programs, and that that's a terrible thing, because of someone they met once who got more than they 'deserved' from the system.

There's a whole psychology there which is missed by the usual "blame everything on the rich" reflexes. It's a problem which will have to be addressed if any social reforms are actually going to stick, as opposed to being pissed away in tax cuts and whinging about how much more deserving the poor were back before they could afford to treat two major diseases a lifetime.
