"According to the website Nuclear Weapon Archive,[7][8] inside the weapon, the uranium-235 material was divided into two parts, following the gun principle: the "projectile" and the "target". The projectile was a hollow cylinder with 60% of the total mass (38.5 kg). It consisted of a stack of 9 uranium rings, each 6.25 inches (159 mm) in diameter with a 4-inch-diameter (100 mm) hole in the center, pressed together into a thin-walled canister 7 inches (180 mm) long. At detonation, it was pushed down a short smooth-bore gun barrel by a tungsten carbide and steel plug. The target was a 4-inch-diameter solid spike, 7 inches long, with 40% of the total mass (25.6 kg). Composed of a stack of 6 washer-like uranium rings somewhat thicker than the projectile rings, it was secured by a 1-inch-diameter (25 mm) bolt through the rings, that protruded out the front of the bomb casing.
When the projectile and plug reached the target, the assembled super-critical mass of uranium would be completely surrounded by a tamper and neutron reflector of tungsten carbide and steel, both materials having a combined mass of 2,300 kg.[9] Neutron generators at the base of the spike would be activated by the impact."

Az uránium-235 izotóp két részre van szedve. Az egyik a lövedék a másik a céltárgy. A lövedék 38.5 kg (gondolom te csak ezt számoltad), a céltárgy 25.6 kg. A robbanás a lövedéket a céltárgyba ütközteti. (Ahhoz hogy meglegyen a láncreakcióhoz szükséges neutronfluxus a neutronsugárzás visszaverő anyaggal veszik körbe.) Az egész körbe van véve 2,3 t wolfram-karbiddal ami a neutronsugárzást veri vissza. (Na ez nem csak holmi körítés, ha ez nincs ott nem fog robbanni.)
