2,300 new jobs and about $350 million in investment. In September 2020, Kroger announced plans for a $95 million fulfillment center in Romulus, which was expected to create 250 jobs, and aimed to capitalize on the growing online grocery segment. The 135,000-square-foot facility will be built on 22-acre site as part of the Detroit Region Aerotropolis. In July 2021, Ford Motor Company announced that Romulus, Michigan would be the home of its new global battery center – Ford Ion Park – which is accelerating the company’s research and development of battery and battery cell technology – including future battery manufacturing. The new collaborative learning lab represents $100 million of Ford’s $185 million investment in developing, testing, and building vehicle battery cells and cell arrays. Ion Park will house some 200 engineers, researchers and other workers. Employees there will research and test battery technologies and pilot advanced manufacturing techniques to help Ford boost battery cell volumes, improve battery range and reduce costs. Highways in the Sky: Developments in Advanced Air Mobility The proliferation of drone technology and e-commerce, have accelerated Aerotropolis' effort to build highways in the sky, which are a system of low-altitude flight routes at between 40 and 400 feet where lightweight air vehicles would fly, carrying everything from Amazon purchases to automotive parts. In January 2020, the Detroit Aerotropolis licensed the Airspace Link AirHub platform, in partnership with Michigan’s PlanetM and the Michigan Unmanned Aerial Systems Consortium, to establish and test a new low-altitude drone infrastructure in the region and bring new advanced manufacturing prospects to the region. Aerotropolis has since deployed the Airspace Link low-altitude drone infrastructure to its local communities and airports to support the safe use of recreational and commercial drone use. These capabilities provide a new type of Smart City mobility infrastructure supporting the growth of drone operations, drone service providers, drone manufacturing, package delivery and air taxi in the future. The complete AirHub platform, including AirHub for Pilots and AirHub for Government, was developed and implemented for all four Aerotropolis communities. Data from the communities, county, state, local and commercial sources were collected, processed and analyzed to identify relevant hazards and risks associated with UAS operations occurring within Aerotropolis used for building safe “Highways in the Sky” that are in harmony with Aerotropolis community interests. Aerotropolis continues to collaborate with Airspace Link to test drone flight and delivery. On August 19, 2021, it
