Everyone knows jeep as a famous car brand, and can even represent a model, but have you heard of The Sep? It is called because of its positioning as "Sea Jeep". Doesn't it feel a little outrageous?
This also begins with World War II, when the concept of "amphibious jeeps" was quite prevalent (the Germans would blow up the bridge when they retreated, and the Americans were in desperate need of a car that could cross the river). The most famous of these is the GP-A amphibious utility vehicle, aka the "1942 Seep Jeep".
Show you an original video of a Ford GPA Seep G504 amphibious jeep "swimming" with the U.S. military during World War II.
The model was designed by Marmon-Herrington and shipmaker Sparkman & Stephens, and was modeled after Ford's GPW model.

When designing the prototype, Engineers at Ford named the model "GP," which is said to be abbreviations for "General Purpose" and "Government Purposes," respectively. Although american television host R. Lee Ermey said on his show years later that the "G" in the name may refer to "government use" and "P" means that the wheel size of the model is 80 inches (about 2.03 meters), in any case, the acronym "GP" became synonymous with the new reconnaissance vehicle at the time, and its harmonic "Jeep" has since become the official name of the model.
Back on the GPA Seep, it's handled like a regular Jeep, except that it has two more handles behind the gear lever, one of which controls the propeller and the other that operates the bilge's air pump.
GPA Seep, which began production in 1942, was not as popular with Allied soldiers as Willis and GPW. Because it is too heavy, far more than the original setting reached 1600KG. When you get to the shoal, it is particularly easy to get stuck in the car; and because the car is not large, it cannot carry many required items, and as soon as there is a wave, it will enter the water and sink in the water. Soldiers also wore life jackets when they went to war, and soon it earned the nickname "Big Bath".
So in March 1943, after producing 12,778 units, the GPA Seep ceased production.
In 1945, World War II ended in the utter defeat of the Axis Powers, but the popularity of this particular model among civilians did not fade. An Australian engineer, Ben Carlin, has spent a full 9 years since 1950 driving a modified Ford GPA amphibious jeep around the world.
The first motor vehicle seen on Komodo Island was this Ford GPA.
After 1970, the world war II collection fever rose, and the Ford GPA became very popular due to its rarity and specialness, and frequently appeared in various exhibitions.
He also attended the Normandy landing commemoration, which was compared to the situation of being ridiculed by the crowd as a "big bath", which was a salted fish turned over.
