Marsh Space

Marsh's Space Practice is the world's leading space insurance brokerage — part of Marsh McLennan (NYSE: MMC), the global professional services firm — providing comprehensive insurance advisory, placement, and risk management services to satellite operators, launch service providers, governments, and investors across the full lifecycle of space missions from pre-launch through end of operational life.

Founded in 1871 and headquartered in New York, Marsh's Space Practice operates through dedicated space insurance specialists in its London, New York, Paris, and Singapore offices who maintain relationships with the specialized underwriters and syndicates at Lloyd's of London (where 90%+ of the world's space insurance capacity is placed), as well as specialty insurers including AXA XL, Allianz Global Corporate & Specialty, and Munich Re's space reinsurance team.

Marsh places insurance across all phases of the space insurance value chain: pre-launch coverage (protecting against delays, vehicle accidents during transport and integration), launch coverage (the highest-risk phase, covering the rocket and satellite during ascent through initial orbit insertion), in-orbit life coverage (annual or multi-year policies covering GEO satellites against random failure of components, transponder degradation, attitude control anomalies, and debris collision), third-party liability coverage (protecting operators against claims from property or personal injury damage from satellite reentry debris), and specialized coverage for commercial human spaceflight operators.

Marsh's scale — the broker for dozens of the world's largest satellite fleet operators, national space agencies, and launch vehicles — means it has actuarial data on satellite failure modes, orbital debris risk at different altitudes, launch vehicle reliability statistics, and in-orbit anomaly frequencies across the entire global fleet that no individual operator or insurer possesses. This information asymmetry advantage enables Marsh to structure optimal coverage terms, challenge insurer premium assumptions with historical data, and advise clients on risk mitigation measures that reduce premiums. Marsh competes with Aon's space practice and Willis Towers Watson as the three dominant space insurance brokers globally.
