New Glenn has demonstrated reuse, and once it returns to flight (1H of 2027) it should quickly reach a monthly cadence with 3X the lift capacity of Neutron. New Glenn has a bajillion dollars of Artemis related launches on the books.

By contrast Neutron is likely to debut in mid- to late 2027 (if lucky, IMO). Even assuming early successes, it will have a slow ramp up. That's just how it goes with rockets. I would say three launches in 2028 would be a solid target.

Big picture: Blue Origin has been extremely capital inefficient over a quarter of a century. But it is simply difficult to compete with a company gifted ~$30 billion from a wealthy founder. And under Dave Limp Blue Origin does appear to be becoming more efficient and better run. Blue Origin is going to have multiple pads and massive factories to build engines and rockets. It has a huge workforce. What Rocket Lab has done with its resources is impressive, but it's difficult to compete with that kind of scale, and scale matters in launch.
