The verdict

Orbital Sciences Corporation runs at 13% of its industry's injury rate - far safer than the typical Space vehicles, complete, manufacturing workplace, earning a grade A.

Orbital Sciences Corporation: 0.4 TCR = 13% of Space vehicles, complete, manufacturing BLS 3.3 · 4y Form 300A (see methodology below)

Orbital Sciences Corporation safety composite

Orbital Sciences Corporation scores strongest on total case rate (tcr) (safer than 72% of same-industry peers) and weakest on dart rate (safer than 31%), 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).
