Lee components have been involved in spaceflight since before NASA existed, contributing to space exploration, telecommunications, satellite observation, and recent commercial New Space efforts.
From the glory days of the space race to the burgeoning commercial spaceflight boom, components from The Lee Company 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. Lee components have served on the space shuttle and are currently serving on the ISS. Those found in the Voyager spacecraft are presently located outside the solar system.
The Lee Company is one of the only organisations with both a pedigree that extends to the dawn of spaceflight and the capacity to supply high-quality products in the volumes necessary to equip constellations with thousands of satellites. We currently supply components used in purge, pressurisation, propulsion, thrust vector control, thermal control, life support systems, and more. We also provide a steady stream of innovations, such as:
These result in launch vehicles and spacecraft that are safer, more reliable, and can achieve better performance. In addition, we can contribute to lowering the cost of launch, as our products are among the smallest and lightest available.
Lastly, The Lee Company can offer a level of expertise that far exceeds our range of off-the-shelf products. Our solutions include but are not limited to plugs, flow restrictors, safety screen filters, and valves such as check valves, relief valves, and solenoid valves, and each can be customised to fit your unique needs. In other words, you can save your engineering time and resources by utilising our experience in developing miniature precision components.
Our custom products may represent a departure from traditional designs, but they’ll never represent a risk. Each custom component relies on one of our field-proven designs. Our components (both standard and custom) are manufactured under a rigorous quality management system (QMS) and put through extensive acceptance testing. This helps our spaceflight customers eliminate risk when failure is not an option.
Our miniaturised components are designed and tested to withstand the extremes of temperature, pressure, and vibration associated with launch and operation in space.
