Millennium Space Systems: A Boeing Company: 0.4 TCR = 11% of Developing and producing prototypes for complete guided missiles and space vehicles BLS 3.3 · 6y Form 300A (see methodology below)

Millennium Space Systems: A Boeing Company safety composite

Millennium Space Systems: A Boeing Company scores strongest on total case rate (tcr) (safer than 74% of same-industry peers) and weakest on fatalities (safer than 51%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
