F35 jet has crashed into the sea...why?

Those figures, we call serviceability rate in our Airforce, are about right.  Though at 75SQN (F18s, years back) we had a rate of pretty mush 87% at all times.  That's because that SQN had part priority over other SQNs.  77SQN was around 72% serviceability at best of times.

That said, they calculate mission capable rate differently to Australia. We count the serviceable rate of Acft ready for flight in the morning or ready for planned missions.   A lot of all nighter's were done at 75SQN. 

I noted the F35 rate dipped then rose.  They might be sorting their parts issues.  But the F22 rates are abysmal.   Maybe they are having modifications or structural fixes.  Maybe they spend a lot of time fixing surface coatings?

I wasn't referring to a standoff weapon, but something more like an automated stealthy loitering bomb truck, or a mortar which lofts smart munitions.  But the idea relies on soldiers equipped with localizers to mark targets and I am not aware of any serious development in that direction.

Update: something I did not notice until after writing this post is that they are enhancing the standoff weapons capability of the A10.


--- Quote ---The JSF F35 was supposed to replace A10.   Using a $100M tool in replacement of a $20M tool, and the F35 cannot do half the close ground support job, has now been recognised as, "stupid".

I agree that whatever would be required to replace the A10, the F35 is not it.

I didn't think the F35 COULD take off horizontally from an aircraft carrier? That was the prime reason for there being a vertical take off version, so it could be used on carriers?

The graphic in that dailymail aricle is probably total bunk. The plane was presumably taking off vertically, and had an engine or fan failure. Hence the pilot coming down close enough to get hung up over the ship's side, hanging by the snagged parachute. If we can believe _anything_ in the press about the event.

The story about the rain cover - over what? The wing air intakes? Or the top fan intake (which has a hatch anyway.) Either it got sucked into a fan or it didn't. If it did, how could it be found floating on the sea afterwards?

Methinks they just don't want to admit it had an intrinsic power plant failure on takeoff. Because that might imply the plane is a 35M$ lemon. (Which it is.)
Monkeh:
No, it wasn't and cannot practically take off vertically.

..its just the inevitable consequence..of what happens when you outsource  much of your general electronics industry to the other side of the world. You loose the skills[1]. The same skills that are needed in the F-35. Not to mention that general electronics is the foundation of the rest of electronics......you lose general electronics, and  you lose a big chunk of every other part of electronics, eg, the more specialist areas....because you have lost general electronics.

The pilot, all the way up to, and going up that ramp, appears to not be in control of that F-35...its going too slow...just thank goodness the pilot got out alive....i wouldnt mind betting that unfortunately the poor chap has damaged his spine getting ejected though...that was always a problem with these ejections...probably still is.....can you imagine it happening if your back wasnt totally straight....ejected pilots get  sent for MRI scans immediately following any ejection.

Wouldnt even surprise me if some bias power supply supplying a processor just didnt work...something as simple as that.
If it was a rain cover...then howcome he didnt realise straight away that something was amiss.....and howcome the sensors didnt report it.

[1]....correction "lose the skills"
