Re: Boeing to test experimental rocket engine - from Rocketdyne Propulsion & Power busin

test of experimental rocket engine

I was surprised to see that so many companies were working collectively to achieve this goal.
Not quite enough in the article to tell where they will be used.

Capable of generating about 250,000 pounds of thrust, the Integrated Powerhead Demonstration or IPD ranks as a booster-class engine and is the first full-flow, staged-combustion engine produced in the U.S. It has been designed as a re-usable engine system, and features hydrostatic bearings ­ already being implemented in the Boeing/Mitsubishi Heavy Industries MB-XX engine ­ as well as exotic new materials.
Rocketdyne provides the turbopumps, thrust chamber assembly and system components, and serves as the lead system integrator, while Aerojet is responsible for all preburner and nozzle work.

250,000 pounds of thrust.

Does that mean heavy lift without SRB?

It is an LH2/Lox engine about half as powerful as an SSME.  The main goals of this program are to demonstrate technologies that will significantly improve engine reliability and lifetime.
