The U.S. Secret Service has grown from a small bureau staffed by a few operatives in 1865, to a law enforcement organization of nearly 7,000 employees worldwide. Today, the U.S. Secret Service fights crime on a global scale through its field offices located in the United States, Canada, Mexico, South America, Europe, Africa and Asia. The agency works closely with local, state and federal law enforcement organizations. These entities are valued partners of the Secret Service, and they are integral to the agency’s investigative and protective endeavors.
The United States Secret Service is one of the oldest federal law enforcement agencies in the country and ranks among the most elite in the world. With its origin dating back to the end of the American Civil War, the Secret Service was originally founded to combat the then-widespread counterfeiting of U.S. currency. In 1901, the agency was asked to begin its protective mission after the assassination of President William McKinley – the third sitting U.S. President to be assassinated. Today, the Secret Service proudly continues to protect both national leaders and visiting foreign dignitaries while helping to secure the nation’s financial infrastructure through financial and cybercrime investigations.
The image of the presidential motorcade is one of the most commonly recognizable symbols of Secret Service protection. But sleek, black limousines with darkened windows and advance security elements were not always features of the presidential limousine.

Advent of the Armored Limo - 1941
With the United States' entry into World War II, the Secret Service increased its protective web around the President. In December 1941, Franklin Roosevelt became the first President to use an armored vehicle. Originally belonging to infamous gangster Al Capone, the car was seized by the Treasury Department in 1932 on an income-tax evasion charge. The car's armor actually was comprised of only bulletproof glass; the body of the car was still vulnerable. The vehicle was used until limousines in the presidential fleet – such as the 1939 Lincoln “Sunshine Special”– were armor-plated in the early part of 1942.
Railroad Horse Car - 1944
Before utilizing today’s methods of transporting vehicles for protective visits by airplane, in the old days, the President's limousine and follow-up vehicles were driven across the country for use upon the President's arrival. Soon however, the agency realized that the distance needed to transport each vehicle produced wear and tear on the vehicles as well as driver fatigue, so the search for alternative means of transportation kicked into full gear. Beginning in 1944, the Secret Service transported motorcade vehicles using a revamped railroad horse car that could hold four automobiles. It was fitted with portable ramps so that the vehicles could be loaded on and off the railroad car quickly. The railway car also was equipped with water tanks to wash the cars en route and held racks for extra tires and accessories for emergency maintenance. For overseas destinations, the vehicles were loaded aboard ships.

The limousine included a series of removable steel and transparent plastic roof panels that could be installed in various combinations. It also contained a hydraulically operated seat, which could be raised 10 ½ inches to give the gathered crowds a better view of President Kennedy and his fellow passengers. After President Kennedy's assassination in 1963, the entire vehicle was armored and returned to the Secret Service in May 1964. The finished product weighed about one ton more than the original weight of 7,800 pounds.
Air Travel - 1965
In the 1960s, air travel began to provide the Secret Service a much more convenient and effective means of transportation. Official vehicles were able to be loaded aboard aircraft to destinations in advance of protective visits.
President Ronald Regan - 1981
The 1972 Lincoln Parade Limousine was used by President Ronald Regan on Inauguration day, January 20, 1981. In the aftermath of the assassination attempt on President Reagan on March 30, 1981, the vehicle was returned to the Ford Motor Company for refurbishing. It received a new interior and the exterior was updated to appear as a 1979 Lincoln.
President George W. Bush - 2005
On Inauguration Day 2005, President George W. Bush rode in a 2006 Cadillac DeVille Touring Sedan (DTS). The limousine actually was a refurbished 2005 model that gave the appearance of the 2006 Cadillac, available to the general public. The vehicle was wider, longer and taller than its predecessor.
President Barack Obama - 2009
President Barack Obama travels in a 2009 customized DTS Cadillac that was in production for two years prior to being unveiled on Inauguration Day. Slightly more upright than its predecessor, the vehicle features 19.5 inch wheels and enough room for five seated passengers. The interior is ornate, complete with a fold-out desk for the President. The limousine is designed to Secret Service specifications, which includes a heavy duty chassis, extended length and armored material, and offers the President secure communications with encrypted measures. At the time, the Assistant Director for the Office of Protective Operations noted,
The Secret Service continues to be responsible for procuring, driving, maintaining and securing the vehicles at all times. Each vehicle is outfitted with a variety of equipment to provide the protectees with a secure environment throughout the entire trip. As the agency has adapted its protective and investigative responsibilities to keep pace with evolving security needs, the Presidents' limousines too have changed over the years to reflect the tastes, needs and security considerations of each generation.
