Take a look at 'The Beast,' the $1.5 million bulletproof presidential limousine used by Trump and Biden

US presidents travel in a secure limousine nicknamed "The Beast."

US presidents rode Lincoln limousines for most of the 20th century until the 1980s, when the Reagan administration switched to Cadillacs.

The latest model of the presidential limousine was commissioned by the US Secret Service in 2014 and used for the first time in 2018 by President Donald Trump.

Designed to look like a longer version of a Cadillac XT6, the chassis of the car is actually that of a Chevrolet Kodiak truck produced by General Motors, NBC News reported. The vehicle weighs around 20,000 pounds and cost around $1.5 million to build.

The heavily armored vehicle is bulletproof, blast-resistant, and sealed to withstand biochemical attacks.

While details about the limousine's security measures remain classified, NBC News reported that the vehicle features a night-vision system, tear gas firing capabilities, and door handles that can be electrified to prevent intruders.

The windows are believed to be 3 inches thick and the vehicle's armor around 8 inches thick.

"The Beast" is also equipped with medical supplies, including a refrigerator stocked with the president's blood type.

The limousine's secure communications system is able to dispatch the launch codes for nuclear weapons.

The presidential seal appears throughout the design of the car.

The seal, featuring an eagle holding an olive branch and 13 arrows in its talons below a banner reading "E Pluribus Unum" ("Out of many, one"), appears on both the interior and exterior of the passenger door.

The limousine can seat up to seven people.

The interior features water bottle holders and plush leather seats. Previous presidential limousines have also included a fold-out desk, according to the US Secret Service.

"The Beast" travels with the president.

Presidential limousines are transported by military cargo aircraft, such as US Air Force C-17s, for use during the president's travels, according to the US Secret Service.

When abroad, the presidential limousine flies the American flag and the flag of the host country.

When Biden visited the UK in June 2021, the presidential limousine flew both the American flag and the Union Jack.

On Inauguration Day, Secret Service agents change the car's license plates as a new president takes power.

Some presidents have used the Washington, DC, "End Taxation Without Representation" license plates, while others have removed the slogan, Axios reported.

Accompanied by the presidential motorcade, "The Beast" remains an instantly recognizable symbol of the power of the presidency.

"It is safe to say that this car's security and coded communications systems make it the most technologically advanced protection vehicle in the world," the assistant director for the US Secret Service's Office of Protective Operations said of "The Beast, " according to the US Secret Service's official website.
