Louisville Air National Guard Base

Louisville Muhammad Ali International Airport, also known by its former names Standiford Field and Louisville International Airport, is a civil-military airport located in Louisville, Jefferson County, Kentucky. It was constructed by the Army Corps of Engineers in 1941 and remained under Army control until 1947, when it was transferred to the Louisville Air Board for commercial operations. The airport covers 1,500 acres and features three concrete runways.

Initially, commercial service moved from Bowman Field to Standiford Field in 1947, with a proper terminal opening in 1950. Significant expansions occurred in the 1980s and 1990s, including the construction of a new landside terminal and the addition of two new parallel runways (17L/35R and 17R/35L). A $26 million terminal renovation was completed in 2005. As of 2024, the airport is undergoing a major renovation project called SDF Next, which includes over $1 billion in planned enhancements to the Jerry E. Abramson Terminal.

The airport is operated by the Louisville Regional Airport Authority (LRAA). It serves as a hub for UPS Airlines, which operates its worldwide air hub, UPS Worldport, from this location. Worldport is a large facility, measuring 5.2 million square feet, capable of handling 115 packages per second. Due to UPS operations, the airport is a major cargo facility, ranking among the busiest globally. The Kentucky Air National Guard's 123d Airlift Wing is also stationed at the co-located Louisville Air National Guard Base, operating C-130 transport aircraft. The airport was renamed in honor of Louisville native Muhammad Ali on January 16, 2019.
