It is named after Thomas Mifflin, 1st Governor of Pennsylvania, signer of the United States Constitution, and 1st Quartermaster General of the United States Army.Although the borough is heavily residential, it is home to one of America's oldest traditional amusement parks, Kennywood Park. Other employers include advanced naval nuclear propulsion technology research and development facility, Bettis Atomic Power Laboratory; monorail manufacturer Bombardier; US Steel's Mon Valley Works–Irvin Plant; Community College of Allegheny County's South Campus; and the Allegheny County Airport.

Bettis Atomic Power Laboratory is a U.S. Government-owned research and development facility in the Pittsburgh suburb of West Mifflin, Pennsylvania, that works exclusively on the design and development of nuclear power for the U.S. Navy. It was one of the leaders in creating the nuclear navy. The laboratory is part of the Naval Nuclear Propulsion Program, a joint U.S Navy-Department of Energy program responsible for the research, design, construction, operation and maintenance of U.S. nuclear-powered warships. The laboratory was founded in 1949 on the site of the former Bettis Field, named after Cyrus Bettis. It covers approximately 207 acres (0.84 km2). From the Lab's founding until 1998, it was run by Westinghouse Electric Corporation. Bechtel Corporation won the contract to run the laboratory on September 19, 2008 and assumed operation on February 1, 2009, first under its subsidiary Bechtel Bettis, Inc., later under Bechtel Marine Propulsion Corporation. The contract changed hands again when Fluor Corporation, as their subsidiary Fluor Marine Propulsion, LLC won the contract to run the laboratory on July 12, 2018 and assumed operations on October 1, 2018.The laboratory developed Oak Ridge National Laboratory's original design of the pressurized water reactor (PWR) for operational naval use. It built the nuclear propulsion plants for the first U.S. nuclear submarines and surface ships including USS Nautilus, USS George Washington, USS Long Beach, and USS Enterprise.Westinghouse's Nuclear Power Division adapted the PWR design for commercial use and built the first commercial nuclear power plant in the United States, the Shippingport Power Plant in the west hills of Pittsburgh.The laboratory had two supercomputers listed on the 26th TOP500 List (November 2005). Ranked 97 a 1,090 processor Opteron system and ranked 405 a 536 processor Itanium 2 system.The laboratory is also home to the U.S. Navy's Bettis Reactor Engineering School. The school provides a post-graduate certificate program in nuclear engineering with a focus on nuclear reactor design, construction, and operations. It is open only to naval personnel and Bettis engineers. The laboratory had been chosen to develop the Project Prometheus nuclear power source for the JIMO (Jupiter Icy Moons Orbiter) project, however, funding for this program was cancelled in the fall of 2005.

Bettis Field was an airstrip in West Mifflin, Pennsylvania, southeast of Pittsburgh, Pennsylvania, established in 1924. It was named for U.S. Army Air Corps Lieutenant Cyrus Bettis following his fatal accident on Jack's Mountain near Bellefonte, Pennsylvania in 1926.

Allegheny County Airport (IATA: AGC, ICAO: KAGC, FAA LID: AGC) is in West Mifflin, Pennsylvania, United States, 7 miles (11 km) southeast of Pittsburgh. It is the fifth-busiest airport in Pennsylvania following Philadelphia, Pittsburgh, Allentown, and Harrisburg. The airport is owned by the Allegheny County Airport Authority and is the primary FAA-designated reliever airport for Pittsburgh International Airport. Allegheny County Airport was dedicated on September 11, 1931.When it was completed, it was third-largest airport in the country and the only hard-surface airport in the country. It was historically the main entrance to metro Pittsburgh via air from its inception until June 1952, when the Greater Pittsburgh Airport (now Pittsburgh International Airport – KPIT) opened for commercial aviation. Like many historic municipal fields, Allegheny serves small and mid-sized private, corporate and commercial traffic well, but was not built to handle jet airliners. A Boeing 727 owned by Rockwell and two DC-9's however were based on the field for years. One DC-9, owned by Westinghouse Air Brake, operated from the former TWA hangar. Another DC-9 was owned by Richard Scaife. Additionally, political candidates often operate chartered jet airliners into the field. Air Force 2, a Boeing 757, has been on the airport in the 2000s. In May 2017, a Southwest Boeing 737 with 143 passengers en route from Orlando, made a precautionary landing when running low on fuel. The airport is popular among business travelers, being closer to downtown than Pittsburgh International Airport. It is much closer to the densely populated South Hills, Monroeville area and Monongahela Valley. The airport is home to Pittsburgh Institute of Aeronautics (PIA), a large aircraft maintenance school.

The Pittsburgh Institute of Aeronautics (PIA) is a private trade school focused on aviation-related programs with its main location in West Mifflin, Pennsylvania. The institution's headquarters is at the Allegheny County Airport and it has three branch campuses. PIA's aviation programs are accredited by the Accrediting Commission of Career Schools and Colleges.
