Sea level ISP?

Do we know that the 303 ISP figure is the Rutherfords SL performance? It seems to me that the difference is too low between 333 ISP for the vacuum version in vacuum and 303 ISP for the SL version in SL pressure. The merlin 1D has 282 ISP for the SL version in SL pressure and 348 for the vacuum version in vacuum. Is it possible that the 303 figure is for the SL Version in vacuum? there is nothing on the Rocket Lab website that says whether the 303 number is in vacuum or SL pressure.

Someone updated for the recent updates from Rocket Lab, but I think the updates reflect the same error you suggest. The update lists the sea level ISP as 311s, but from context this is clearly the vacuum ISP of the first stage version of the engine, and the 343s number is the upper stage version of the engine. The difference is analogous to the Merlin 1D and the Merlin 1D Vac. To my knowledge Rocket Lab has not disclosed the sea level ISP of the current version.

Move discussion in progress

There is a move discussion in progress on Talk:Curie (rocket engine) which affects this page. Please participate on that page and not in this talk page section. Thank you. —RMCD bot 05:05, 14 August 2020 (UTC)[reply]

I think this should be moved

It should be moved to "Rutherford (rocket engine)" to fit with Curie (rocket engine)

Not sure why it says RocketLab in the title
