Following a successful first launch of the Space Launch System (SLS) and its critical Core Stage, Boeing is looking ahead to “the SLS fleet” as the aerospace company moves to complete the next three core stages for Artemis missions II through IV

With Core Stage 1’s flight now in the books for Boeing, attention continues to be paid to the future core stages currently in production at the Michoud Assembly Facility (MAF) in Louisiana

Looking further ahead, Zietsman noted that major assemblies for Core Stage 3 are underway and have so far been executing well to that mission’s overall timeline. 

Likewise, build operations are also underway for Core Stage 4, while the core for Artemis V is currently having parts and equipment ordered for its eventual build and assembly

However, the Core Stages for Artemis IV and beyond will be different from those that come before as they need to accommodate a much larger upper stage in the EUS
