Martin, a pioneer aviation designer and constructor, purchased 1,260 acres for an aircraft manufacturing site for the Glenn L. Martin Aircraft Company • His company employed more than 50,000 workers in the Baltimore area during World War II, most of whom worked at this facility. • At one point during WWII, the facility became the largest and most advanced aircraft manufacturing complex in the world. • While in operation, this facility produced more than 11,000 planes.

Martin employed 52,474 workers in the Baltimore area, most of whom commuted from Baltimore by car every day. The roadways became so congested, a December 1941 issue of LIFE magazine featured a story on the severe traffic jams (photos shown) Due to high demand and needing to solve the congestion, the State of Maryland built two new high-speed “divided highways,” Eastern and Martin Boulevards. They crossed in front of the Martin plant in what is probably Maryland’s first cloverleaf interchange. In addition, they extended new water and sewer lines to Middle River which provided the infrastructure to develop new housing.

Martin first provided trailers, then began to develop residential communities such as: Stansbury Manor Aero Acres Background MTN State History Aero Acres • Commissioned by Glenn L. Martin and designed by S.O.M Architects • 600 prefab homes only $30-$35 a month • Street names such as Fuselage Avenue, Cockpit Street, and Helicopter Street Victory Villa MTN • The Federal GovernmentStansbury Manor followed suit, building more than a thousand• Glenn homes L. Martin’s first residential • Wood panel prefabsdevelopment in a more traditional design • Aeronautical street• Gardennaming apartmentscontinued (Runway on Wilson Point Court, Taxi Way,• Manifold$65 a month, Court) too expensive at the time Shaping the Community Background MTN State History Impacts on Aviation and Aerospace Industry The Martin Company employed many of the founders and chief engineers of the American aerospace industry William Boeing took flight training at the Glenn L. Martin school in LA, and ordered his first plane from the Martin factory The Martin Company consolidated with the American Marietta Corporation in September 1961 to form the Martin Marietta Corporation In 1995, the merger of Martin Marietta and Lockheed produced the Lockheed Martin Corporation, one of the world’s premiere technology companies. Lockheed Martin still maintains an active presence at MTN, occupying a large hangar at the airport. They also own a large facility along Wilson Point Rd. where they employ about 470 people doing aircraft parts assembly.

From 1955- 1958 the 104th unit was charged with defending the Baltimore-Washington area against possible Soviet bomber attacks. The unit relocated to the Glenn L. Martin Company Airport in 1957, whose longer runway was 1955 - 1958 necessary to support jet operations. •135th Air Resupply Group was organized at Harbor Field. Following the closure of Harbor Field in 1960, this unit also 1960 relocated to the Martin Company Airport. •The military facilities at Martin State Airport were formally renamed in honor of Maj. Gen. Edwin Warfield III, former adjutant general of Maryland, in 1982, and the base has since been 1982 known as Warfield Air National Guard Base.

Therefore it cannot be demolished or removed. • Distance from the existing cab to physical paved Runway End 33 makes detection and recognition of aircraft and/or vehicles difficult in that area. • Current ATCT Relative Cab Eye Height is 42 feet AGL (59’ MSL), with a roof height 53 feet AGL (70’ MSL) • Controllers must take stairs to the roof of the administration building and walk outside to reach the cab (accessed from the roof) • In addition, A new tower is needed based upon the existing tower’s age (1945), physical condition, and remaining service life Purpose Existing ATCT Runway 15/33: Existing Length 6,997’ Ultimate Length: 7,430’ Siting Process • FAA Order 6480.4B, Airport Traffic Control Tower Siting Process • Chapter 8 – Alternate Siting Process • Development of a Safety Risk Management Document (SRMD), which includes: • Siting Report • Comparative Safety Assessment (CSA) • Functional Hazard Assessment (FHA) Project Timeline Approx.
