Product Description

The Rocketdyne F-1 liquid-fueled rocket engine, developed by Rocketdyne (later Rockwell International), powered the Saturn V S-IC first stage that carried the Apollo lunar missions. Plaintiffs allege in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that the F-1 engine as installed on the S-IC stage was equipped with an asbestos-fabric heat shield blanket protecting the thrust chamber and adjacent structure from radiant heating and with asbestos-refractory nozzle throat insulation designed for the extreme thermal environment of first-stage ignition. Plaintiffs allege these materials were selected for their high-temperature ablative and insulative performance.

Workers Exposed

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that occupational exposure to alleged F-1 asbestos components occurred among:

  • Rocketdyne engine assembly technicians fabricating and installing asbestos-fabric heat shield blankets
  • Rocket engine test-stand mechanics at Rocketdyne test facilities performing pre- and post-firing service
  • NASA and aerospace-contractor propellant technicians supporting stage integration
  • Kennedy Space Center / Cape Canaveral integration technicians during S-IC stage mate
  • Pre-flight refurbishment crews removing and replacing scorched heat-shield sections

Alleged exposure pathways included dust and fiber release during blanket fabrication, cutting, and installation and disturbance of asbestos-refractory nozzle throat material during pre-flight inspection and post-test rework.
