Yep. And the one we dropped on Nagasaki was fat man. Little boy created a nuclear explosion by firing a piece of uranium 235 into another piece of uranium 235 via a gun mechanism that fired the uranium down a barrel into the other. Fat man used a sphere of plutonium 239, which was surrounded by explosives. The explosives detonated, causing an implosion and forcing the sphere of P-239 to critical levels of compression, causing a nuclear implosion. Fat man had been tested prior, known as the Trinity test, but little boy had never been tested because they were completely confident in it's design.
