Also this year, we'll start full-engine testing of the BE-4
'It's performing quite well', Blue Origin Chief Executive Bob Smith said of BE-4 on the same panel as Bruno. 'We've gone through several hundred seconds of firing, including an over 200-second firing of that engine, so we're feeling very good about its progress and what we're going to be able to deliver to the market, as well as for our own consumption.'

[550,000 lbf thrust rocket engine] performance can involve a lot of wear and tear, particularly if you're using traditional ball and roller bearings. To maximize the engine's reusability, Blue Origin's team is taking a different approach. To keep the BE-4 running smoothly, Bezos says the turbine at the heart of the engine's turbopump will use a thin film of the fluid propellants as its bearings.
