To be frank, it is not worth buying more until these things (ainonline June reporting from Farnborough) have been tested, not in isolation (unit test with the engine in 2019) but with proper integration test (that is only starting next year with the newest - once again patched - 3F incarnation of JSF).
"P&W is offering the new optional package as a result of the perceived need for an improved power and thermal management system (PTMS) to accompany the upgrades to the F-35 that Lockheed Martin is proposing. Lockheed Martin describes these as a continuous capability development and delivery (C2D2) strategy, but some are also known as the Block 4 upgrade.
The upgrade program is scheduled to begin next year but is still under negotiation by the F-35 Joint Program Office.
The Growth Option 2.0 upgrades will result from P&W’s adaptive-cycle R&D effort focusing on third-airstream capability, adaptive-cycle controls, and new materials, with the company planning to “take the technologies as they mature and insert them into existing engines,”
So, 2019 (at least) for both the integrated SW and the new engine, in isolation. Then P&W says 4 years for the actual prgrm, to get a production rate engine
... and voi la! It will be 2024, when we are due to complete with deliveries in Jan. The rest of the decade might be taken up by the upgrades needed to be made to the early batch - who knows?
A mere coincidence? Or keeping mushrooms in the dark and (drip)feeding with...
- whether we have any money or not; that's the question
- at least we will have put ourselves into a position where there are real (VFM & mature) options
