F-35 Block 4 – Total Crap
11th September 2025
As you know, the F-35 does not yet have its full combat capabilities. Those were part of the incremental Block software upgrades and should have happened years ago. Now, the Block 4 upgrade effort has been delayed yet again.
The Pentagon now anticipates the F-35’s Block 4 modernization won’t be complete until 2031 at the earliest, a five-year delay from its original timeline, even as the department rescopes the effort to include fewer capabilities than originally envisioned … [1]Note the phrases,
“at the earliest”
“include fewer capabilities than originally envisioned”
You know, beyond the slightest shadow of a doubt, that the even the much delayed 2031 date will slip further still and the already downgraded capabilities of the Block 4 will be further downgraded. Honestly, at the rate we’re going, Block 4 isn’t going to deliver much in the way of new capabilities, at all. Many features have already been deferred to a nebulous, non-existent. Unfunded, future upgrade instead of the Block 4.
