Just When You Thought that the JSF Could Not Get Any More f%$#ed………

We now find out that they bought into Lithium Ion batteries for the fighter, the technology that has grounded the 787:

The Pentagon said it plans to continue using lithium-ion batteries on the new F-35 fighter jet despite problems with similar batteries that have grounded Boeing Co’s new 787 airliner and are causing Airbus to rethink their use on its A350 jet.

Joe DellaVedova, spokesman for the Pentagon’s $396 billion F-35 program office, said on Tuesday that the lithium-ion batteries used on the new radar-evading fighter were made by different manufacturers than those used on the 787, and the jet’s battery systems had been rigorously tested.

“The bottom line is the lithium-ion batteries used on the F-35s have been through extensive tests and have redundant systems to protect the aircraft and battery compartments; they are considered safe,” DellaVedova said.

DellaVedova said there had been some irregularities with the lithium-ion batteries not starting properly in cold temperatures that were being addressed, but no issues affecting flight safety had come up during years of testing.

All 50 Boeing Dreamliners in commercial service were grounded worldwide on January 16 after a series of battery-related incidents, including a fire on board a parked 787 at Boston’s Logan International Airport and an in-flight problem on another airplane in Japan.

The groundings have cost airlines tens of millions of dollars, with no solution yet in sight, and have sparked growing concerns among aerospace industry executives about whether the powerful but delicate backup energy systems are technically “mature”, or predictable.

Why am I not surprised?

When you cross reference "advance technology", "unproven", and "risky", the Venn diagram of the intersection is the JSF.
