Joint Strike Fighter, Sammelthread Einstellungen

[Praetorian]

Da wir gar keinen eigenen Thread zum JSF hatten und das ganze Vorhaben aktuell sowohl finanziell als auch bei Exportentscheidungen vor wichtigen Entwicklungen steht, war ich der Meinung, wir könnten einen der allseits beliebten Sammelthreads gut gebrauchen

Da will ich auch gleich mal mit einem Beitrag von Bill Sweetman, Chefredakteur von Defense Technology International, bei Ares einsteigen, in dem er einen Blogbeitrag des berühmt-berüchtigten Loren Thompson genüsslich seziert. Und den ich viel zu gut finde, um ihm nur ausschnittsweise zu zitieren

1. The F-35 program is meeting or exceeding every one of its key performance parameters.
"Is projected to" might be better, since not one KPP has yet been demonstrated.

2. The testing program to date has uncovered no significant design defects or problems.
This would be unsurprising if it were true, since there hasn't been much testing, but if the thermal issues and problems with the ejection seat aren't significant, the flight control failure on AA-1 certainly is.

3. The designs for all three versions of the plane are complete, and all three have been built.
Nine years into the program, it would be nice to know that the designs are complete.

4. Weights, strengths and radar cross sections in early planes are matching planned goals.
The different variants are 2700-4800 pounds above the 2002 empty weight targets. (Yes, I have the program documents.)

5. Software reliability is 20 times better than on the F-22 fighter at the same stage of development.
Define "at the same stage of development". Nine years in? Six years ahead of IOC?

6. The production plan is only running six months late, and that lag will continue shrinking.
Delivery of all 12 aircraft to flight test centers will not now take place until February 2011 - six months later than predicted in September 2009, at which point they were already an average of six months late.

7. 16 of the 19 developmental aircraft have been delivered, with the rest arriving by June.
That is, if you define non-flying airframes as "aircraft" and aircraft that have not yet flown as "delivered" but most of us don't do these things.

8. The cost of each aircraft fell 50 percent between the first and fourth production lots.
As it should. That's called the learning curve.

9. Projected fleet prices for all three variants of F-35 have been stable for several years.
Exactly. What we found out on Thursday was that the projections were wrong.

10. 157 flight tests have been completed, with over 70% of planes ready to fly again after routine maintenance.
And the single Gripen NG has completed 117 flights in less time.

11. Over 80 percent of the development program has been completed, with excellent early test results.
What does this mean? How can any part of the development program be "completed" without flight tests on the airplane itself?

12. Despite the complexity of building three variants, the program is progressing better than previous fighter efforts.
There are people in St Louis who would disagree with this. And the F-22 was not six years late, despite being treated much more harshly by Congress than JSF has been so far.

PARIS AIR SHOW NEWS: Lockheed Planning Major Increase in Range, Other Capabilities for F-35

6/17/2019
PARIS — The Lockheed Martin-built F-35 joint strike fighter will receive additional capabilities in the coming years including significantly enhanced range, weapons capacity and manned-unmanned teaming options, a company executive said June 17 at the Paris Air Show.
[...]
“We talked to several customers about how do we extend the range of the airplane,” Ulmer told reporters during a briefing. “We're looking at conformal fuel tanks as well as external fuel tanks on the airplane to increase the range” by about 40 percent. The F-35A currently has a combat radius of about 590 [669] nautical miles.

Other capabilities are slated to improve. By the time of Lot 15 production, Lockheed aims to increase the internal weapons bay capacity from four to six missiles and integrate new weapons into the aircraft. The fighter could potentially externally carry new hypersonic weapons that the Pentagon is pursuing, he noted. Hypersonics can travel at speeds of Mach 5 or faster and are highly maneuverable, posing a major challenge to enemy air defenses.

New sensor fusion capabilities could facilitate multi-domain operations such as missile defense, Ulmer noted.

“We've done some experimentation here and seen some very strong results as well, and that will only improve” with the technology refresh, he said.

The sensing and communications capabilities could enable the jet to team with unmanned systems, he added.

“The data sensor fusion approach to the airplane as well as our relationship with our brethren at the Skunk Works [division of the company] I think very well align relative to unmanned teaming and the F-35's ability to play in that realm,” he said.

Lockheed is planning other classified upgrades to the aircraft, which Ulmer declined to discuss.

Echt jetzt Dave? Nimmst du nun schon unkommentiert Änderungen an Artikeln vor, die du zitierst, weil du glaubst deine Daten wären besser als die, die der Artikel nennt?
