The headquarters and main rotorcraft factory is in Ridley Park, Pennsylvania, a suburb of Philadelphia.
Production of Apache attack helicopters in Mesa, Arizona, formerly part of Rotorcraft Systems, is now under the Global Strike Division of Boeing Military Aircraft.
For much of the 1970s, Boeing Vertol entered the railroad rolling stock market in an attempt to keep government-funded contracts in the wake of the Vietnam War.
During this period, Boeing Vertol manufactured the Morgantown Personal Rapid Transit system for West Virginia University, the 2400 series Chicago 'L' cars for the Chicago Transit Authority, and the US Standard Light Rail Vehicle (marketed as the Boeing LRV).
[4][5][better source needed] While the company's subway cars performed better, they did not continue in the railcar business, as competitors may have underbid on a key contract[citation needed] and the post-Vietnam War military build-up provided far more lucrative military contracts.
