F-35 engine upgrade hits delay, casting doubt on timeline
Critical design review has been pushed back a year, according to Pratt & Whitney.

PARIS—A key milestone for the Pentagon’s program to upgrade the F-35 engine has been pushed back a year, raising questions about the overall timeline of the effort.

The engine upgrade will reach “critical design review,” a milestone that essentially closes the design phase of the program, by “mid-next year,” according to Jill Albertelli, president of military engines for Pratt & Whitney—a year later than Pratt previously estimated.

The upgraded engines were supposed to hit the fleet by 2029, but Albertelli declined to confirm whether they will be ready by then, deferring specifics to the F-35 Joint Program Office. JPO did not respond in time for publication.

“We were working the timeline with the JPO because many things have to come in place: obviously I have to design, develop the engine, test it, deliver the hardware, all of that. But you also have certification with the jet, so we're working very closely with Lockheed and the JPO on that timing. So we'll see how that ends up,” Albertelli told Defense One on the sidelines of the Paris Air Show.

Pratt declined to say why the delay is happening.

If a political party does not have its foundation in the determination to advance a cause that is right and that is moral, then it is not a political party; it is merely a conspiracy to seize power.     -Dwight Eisenhower-

"The [U.S.] Constitution is a limitation on the government, not on private individuals ... it does not prescribe the conduct of private individuals, only the conduct of the government ... it is not a charter for government power, but a charter of the citizen's protection against the government."     -Ayn Rand-

Correction.  They put their only egg (F-35) in their only (single contractor) basket.  Time to get more hens, more eggs, and more baskets.  Maybe get some quail and ostrich, too.

  • I was a "conspiracy theorist". Now I'm just right.

Seventeen Techniques for Truth Suppression

Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.

C S Lewis
