Products: satellite-servicing, robotic-arm. Risk band: Low RobotRisk index 9.0/100 (incidents/exposure, time-weighted) · 89th percentile of 118 defense space companies.
The register carries a single entry for Northrop Grumman: a September 2025 propulsion issue that delayed Cygnus XL's arrival at the ISS, classed as a disruption at severity 2. Index and percentile place the company at the low end of the defense-space category, 89.7th percentile, indicating fewer and less severe recorded events than most peers in the category. The record is a single-event profile with no fatality, injury, or recall history present, and no trajectory can be established from one data point. The event is operational and mission-related rather than safety-critical in the recorded severity terms, and the source is press/mission-status reporting rather than a regulatory action.
