Baltimore Municipal Airport Baltimore Municipal Airport ( also known as " Harbor Field " ) is a former airport and United States Air Force military airfield located about 6 miles southeast of Baltimore , Maryland on an artificial peninsula . Construction began in 1929 and was completed in 1941 . It was closed on 30 December 1960 . The western half of the airport was located within the city of Baltimore , whereas the eastern half was in Dundalk , in Baltimore County . Today , the former airfield is the site of the Dundalk Marine Terminal , a multi - use shipping facility . History . Construction of the new " Baltimore Municipal Airport " began in 1929 under authority and exertions of the municipal government of the City of Baltimore . The airport was planned as a replacement for the smaller previous Logan Field , which was located adjacent to the planned site of the " Baltimore Municipal Airport " . It was constructed on an artificial peninsula built from dredged harbor silt alongside old Colgate Creek on the " Patapsco Neck " peninsula ( which ends and juts out into the Chesapeake Bay between the Patapsco River to the south and Back River ( Maryland ) in the north at Sparrows Point and North Point ) . Lower Colgate Creek flowed into the Patapsco River and is today the site of the Dundalk Marine Terminal facility of the Helen Delich Bentley Port of Baltimore . A seaplane facility was opened by Pan American Airlines in 1932 , and by 1937 Imperial Airlines began operation out of the airport ( seaplane use subsequently declined , and by the end of 1940s the seaplane facilities had fallen into disuse ) . Various commercial airliners and " Pan Am " seaplanes ( known as " Clippers " ) used the facility until World War II . Problems with the harbor silt led to lengthy delays and the facilities for land - based aircraft weren ' t ready for use until 1941 . All normal civilian traffic was suspended in 1942 , when the United States Army Air Corps took over the airfield . The Army Air Corps used Baltimore Army Airfield as a I Fighter Command training airfield . Units assigned to the airfield were the 324th Fighter Group ( 6 July - 28 October 1942 ) ; 353rd Fighter Group ( 26 October 1942 – 27 May 1943 ) , and the 358th Fighter Group ( 28 April - 28 May 1943 ) . Beginning in 1943 , it was transferred to the Air Technical Service Command as a repair and maintenance sub - depot for the Middletown Air Depot , located near Harrisburg , Pennsylvania . British Prime Minister Winston Churchill departed from " Baltimore Municipal Airport " on a 1942 British Overseas Airways Company ( BOAC ) flight ( today it is " British Airways " ) after visiting President Franklin D . Roosevelt in what was at first , a secret trip to the White House in Washington , D . C . for Allied consultations shortly after America entered the War following the Japanese bombing at Pearl Harbor , on Sunday , December 7 , 1941 . He later met with reporters and addressed a joint session of the United States Congress at the The Capitol . BOAC continued to use Harbor Field as its main U . S . Operating Base during the war . BOAC " flying boat " service to Baltimore Municipal Airport ended in 1948 . Civilian airline service returned to " Baltimore Municipal Airport " after the war in 1946 . However , the airport ' s runways were not long enough for the postwar jet airliners . The airport ' s use was limited to smaller , lower - capacity planes . When Friendship International Airport ( later later renamed Baltimore - Washington International Airport in the 1980s , when it came under control of the new Department of Transportation of the State of Maryland ) ) opened in 1950 , dedicated by President Harry S Truman , near Linthicum in suburban Anne Arundel County , major airline operations almost immediately moved to the new larger , more modern airport . " Baltimore Municipal Airport " was officially renamed " Harbor Field " in 1950 . During the 1950s " Baltimore Harbor Field " continued to serve private pilots and business aviation . It was also used as a Maryland Air National Guard ( MDANG ) base after the war . Beginning in 1946 , the MDANG based its 104th Fighter Squadron at the airport . The squadron was originally equipped with piston - powered P - 47 Thunderbolt aircraft , later replaced by F - 51 Mustang s , but eventually the unit converted to the jet - powered F - 86 Sabre . In 1957 , the 104th relocated to the Glenn L . Martin Company Airport , further to the east along Eastern Avenue in Middle River whose longer runways was necessary to support jet operations . In addition , the Maryland Air National Guard ' s 135th Air Commando Group was based at Harbor Field from 1955 until 1960 , when it too relocated to the Martin Company Airport . That unit flew twin - engine C - 46 Commando and SA - 16 Albatross aircraft . In 1958 , the Martin Company airport was purchased by the recently constituted Maryland Port Authority of the State of Maryland for conversion into a marine terminal for port and maritime business and shipping , ending the use of the facility as an airport . The airfield was officially closed on 30 December 1960 , following the departure of the last Air National Guard unit . Construction throughout the 1960s removed the runways and other airport structures , and by 1971 almost all physical evidence of the former airport were gone . A 1990 historic site survey reported on four major structures from the " Airport Era " which were still extant : the old 1930 ' s " art - deco " - style Pan American terminal , the Air Station , Hangar # 1 , and the Air Guard Building . The Maryland Historical Trust subsequently earlier found these buildings to be eligible for the National Register of Historic Places , based on their innovative design features & their association with local transportation history . In 2005 the former control tower building , which had become derelict , was torn down . Unfortunately , by April 2013 , it was reported by a local historical newspaper columnist in the Baltimore Sun , Frederick N . Rasmussen , that the iconic " Pan Am " Terminal that he had visited five years before had now been razed , and a substantial piece of Maryland ' s aviation history was lost . It is also known that somewhere on the grounds of the former " Logan Field " , " Baltimore Municipal Airport " or " Dundalk Marine Terminal " along the shores of the lower Colgate Creek , was the original location of the first church building for St . Paul ' s Parish of the old Church of England , the established state church then of the colonial Province of Maryland , and one of the " Original Thirty " parishes designated for the Colony and the one for the newly " erected " ( established ) Baltimore County , founded in 1692 , and the oldest church in either the County or the newly established " Baltimore Town " on the north shores of " The Basin " at the head of the Patapsco River . After 1706 , when an official tobacco port had been established at Baltimore Town by authority of the General Assembly of Maryland for shipping and imports , the was enough that local citizens petitioned the legislature to lay out a town which was authorized in 1729 and followed the next year by an official " Original Survey " laying out lots of land . As the official Anglican Church for the County , it was decided to move the Parish to the new Baltimore Town , so Lot # 19 was purchased from Charles Carroll of Annapolis in 1730 and construction of a new building was begun .
