Does Aerojet have any NK-33's left over, or am I remembering wrong? Antares has flown with them before, it should be a able to do it again.

What about the Ukrainian first stages - does NG already have the first stages it needs for NG-18 and NG-19?
Kathy Warden, Northrop Grumman’s president and CEO, said in an April 28 earnings call that the company has “some exposure” to the fallout from the war in Ukraine on the NASA resupply contract.“We have what we need for the next two launches,” Warden said. “So there isn’t immediate disruption, and we have a plan in place that we could use other sources if needed, beyond those two launches.”
[Kurt Eberly, Northrop Grumman’s Director of Space Launch:]"...we have all of the hardware we need for all the missions we have on contract with NASA. So that includes NG-17, 18 and 19. All that hardware is here at Wallops.”

Maybe Aerojet used up all the NK-33s for the Antares rocket, because the NK-33 is an old rocket engine, and the Soyuz 2.1v remains the only SLV in service to use the NK-33.
