Aerojet Rocketdyne - Stennis: 0.6 TCR = 18% of Aerospace BLS 3.3 · 8y Form 300A (see methodology below)

Aerojet Rocketdyne - Stennis safety composite

Aerojet Rocketdyne - Stennis scores strongest on dart rate (safer than 80% 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).
