This is not a small engine. Two of these will give the first stage of
Vulcan more thrust than one Russian RD-180 gives Atlas V.


Note that they've just gotten the first one built, but it's never been
fired. They have a long way to go, particularly at the glacial speed
that Blue Origin usually moves. It has around 2/3 the thrust of a
SpaceX Raptor, which was test fired last year.
