From the glory days of the space race to the burgeoning commercial spaceflight boom, Lee components  have helped propel humankind beyond the atmosphere. Our components were used to supply oxygen to Neil Armstrong when he took his first steps on the moon and in the rocket and lunar lander that helped get him there. They have served on the space shuttle, international space station, and virtually every other significant mission in US and European spaceflight history. Lee products are used in a wide range of systems such as:

  • Propulsion
  • Purge
  • Ullage / Pressurization
  • Reaction Control
  • Thrust Vector Control
  • Stage Separation
  • Landing
  • Thermal Control
  • Life Support


Work with a partner that offers both a pedigree extending to the dawn of spaceflight and the manufacturing capacity to supply high-quality products in the volumes necessary to equip constellations with thousands of satellites. Whether designing a launch vehicle, spacecraft, or satellite, industry mainstays and New Space start-ups choose The Lee Company to provide the lightweight, high performance, reliable components necessary to guarantee mission success.
