The answer to your first question is, no, the BE-4 is not significantly more complicated than the Raptor, though it is quite a bit larger and heavier.

The answer to your second question isn’t likely to be available soon. I suspect that it, along with many other equally good questions about Blue Origin, will only be answered when some long-time insider writes a tell-all book.

If not, why would it take them so much time to get flight articles ready, when Raptor production is approaching 50 (or possibly more)?
