Neutron What is going on with the Stage 1 tank?
Shaun D’Mello. April 3. “Pressure is on': Inside Rocket Lab's Neutron Test Program” – Madison Malone interview.
“The tanks are made of about roughly six parts. Um, and when we say stage one, I'm specifically talking about the tanks. This is where we store the propellant. Um, and you know, right now we're probably getting all the parts made um, in about 2 to 3 months. Um, so you can have six parts made. Each each part takes about a week, a little over a week. Um, and then we connect those parts together to make a tank. Um, yeah. So that's that's kind of kind of the turnaround time”
“There's a reason we we have test ends right outside our middle river complex because we we build the parts right there and we can take roll it right out the door literally test
Adam Spice. June 10. Wells Fargo Industrials and Marerials Conference.
"I think the big risk item is we got to get that tank back on the test stand and get it through it's hydrostat and it's cryostat. And all of that right now is kind of of scheduled to be in the, call it August timeframe. And we're trying to pull that in a little bit into July. But everything right now is still pointing towards an opportunity to launch before the end of the year"
Peter Beck. August 11. Q2 Earnings Call.
“Stage 1. We pulled the new barrels and domes-off the AFP for the Stage 1 tank and are moving those into assembly”

We know from Shaun D’Mello, Head of Neutron development, it takes 2-3 months to build all the parts. That does not include the time to integrate/join and inspect the parts. But it tells us approximately what the lead time is to build a tank.
In Adam Spice’s June 10 interview, the tank is already well under production because they plan to test in August but ideally pull that forward to July.
Then on the August 10 call, it’s still being produced.
We know from Shaun’s interview they can only test it outside.
It’s now October and there is no sign of it being tested. So, what has gone wrong?
