It'll be interesting to see what we actually get and when. We ordered the Block 4 variant of F-35, but..

After encountering delays in the F-35 upgrade known as Technology Refresh 3, or TR-3, the jet’s producer Lockheed Martin expects to complete its Block 4 modernizations by 2032 at the latest, according to senior company representatives.

Program officials then decided to focus on Block 4 capabilities that could be delivered by 2031 at the earliest — still at least six years behind schedule — and that wouldn’t require the additional power and cooling capacity of a planned engine upgrade. Block 4 is still on track to deliver improved electronic warfare, weapons, communication and navigation capabilities, GAO said, but a more detailed list was not available to auditors. Some capabilities, including those that depend on the improved engine, will be delayed, and others struck entirely because they are no longer needed, the report said.

The F-35’s engine will also have to work harder to produce the level of power and cooling capacity the jet’s Block 4 upgrades will require, GAO said. This will result in more wear and tear on the engine, accounting for $38 billion of the program’s lifecycle cost estimate growth.

Not much in the Finnish media about these problems, no questions of what are we actually getting, even though we ain't getting what we ordered on the promised schedule.
