Lockheed Martin manages the supply chain for the production and maintenance of the U.S. Air Force's entire aircraft line. That includes combat aircraft like the F-35, which consists of about 425,000 parts. In total, there are more than 616 million parts used across all aircraft in the U.S. Air Force. Lockheed's warehouse operations have unique challenges like inventory validity and inconsistent productivity due to a lack of trained workers. The work environment can also be incredibly complex, with production line changes happening every time a new aircraft needs to be produced. Lockheed's Rotary and Mission Systems group hoped to alleviate some of these issues by introducing autonomous mobile robots (AMRs) in its warehouses.
