> can’t be updated

You mean the ICP that's already been updated as part of TR3 to support Block 4 features? https://militaryembedded.com/avionics/computers/f-35-program...

The contract modification that the American taxpayer paid over $7 billion for that wasn't released until 2023?

For that you got an update to...

>2900 DMIPS, 1MB L2 Cache 512MB DRAM, 256MB Flash 128KB NOVRAM

So you got to upgrade from an 80486 level to something the equivalent of an early-2000s Pentium II.

You can quibble about cost or timeline or specs, but that's a different argument than saying something that's factually incorrect.
