This will not be a learned more robustly in the US until one or both of the only two (edit: major) gas turbine manufacturers in the world (GE Vernova, Siemens Energy) suffer a tail risk event causing their failure. Backlog for new gas turbines is ~7 years, as of this comment. Continued production capacity is a function of how fragile those two companies are.
Yes, but their production volume is limited (imho) compared to the two companies I mentioned. Good callout regardless. I'll have a post put together to share here enumerating and comparing.
(i track global fossil generation production capacity as a component of tracking the overall rate of global energy transition to clean energy and electrification, but some of my resources are simply an excel spreadsheet)
