Yeah, that BO development seems slow, but they are investing in facilities and talent in the right places. And they are replacing relatively inexpensive, very reliable motors. 

United Launch needs Blue Origin to come through with its engines so they can finally kick the Russian habit! I am super interested in seeing how Relativity Space plays out this year. The 3D printing could be huge but the drawbacks are also pretty big! Axiom Space is another as they are looking to start building their own space station and they are looking into a mission that would actually go to Hubble and help do maintenance on it and lift it further into orbit!

Rocket Lab Returns Previously Flown First Stage to Prepare for First Reflight

Exciting times in aerospace. In the U.S., Relativity Space, Blue Origin - looking to replace the current need for Russian rockets, SpaceX, Ursa Major, Hermeus, Sierra Nevada, Firefly - and I haven't even mentioned The Primes (Lockheed Martin, RTX, Boeing, Northrup Grumman), nor Japan, China, India, UAE, Russia, etc!
