In case you haven't noticed, the Antares rocket hasn't been in the news lately. I looked at the launch schedule and found that this past August was the last launch of the Antares 230 series. The 330 series is still in development and isn't expected to be ready until the summer of 2025. There have been 17 successful Antares launches and one failure.

The 330 series booster is contracted out to Firefly Aerospace and will have 7 of their Miranda RP-1/LOX engines (also to be used on Firefly's MLV) producing about 1.6 million lbs of thrust.

It looks like the Cygnus resupply spacecraft will be lofted by Falcon 9 boosters until the 330 series comes online. There are three scheduled for the F9 and three more scheduled for the new Antares.
