	There's a good article in the latest Av. Week about this.
Yes, they will try to market the RD-170/171.  I don't have the mag
with me right now, but P&W will be the sole rep. for Energomash in
North America (I think).  The time scale for actual engine
availability was undefined (depending on the application, I'm sure).

	Av. Week had a second article on the NPO RD-701, a tri-fuel
engined which burns kerosene, LOX, and LH2, with continuously variable
fuel transition from kerosene to LH2.  Is this to customize the rocket
performance as a function of altitude, load, etc.?  The thrust figures
for all kerosene were significantly higher than with pure LH2.
