What was the purpose of T30 Heavy Tank?

The T30 Heavy Tank's purpose was to provide the United States with a powerful and well-armored heavy tank that could effectively engage enemy armor and fortifications during World War II. The tank was designed to be armed with a 155 mm gun, which would have given it a significant advantage over most enemy tanks at the time. However, the T30 was never mass-produced, and only two prototypes were built before the end of the war.
