I expected something more flashy. This was somewhat subdued performance.
Like the Grand Slam, Tallboy was designed to penetrate the earth, concrete, steel, whatever. To keep it from breaking up when it hit something solid, the tip would be armoured and the sidewalls of the bomb would be thick - the time delayed detonator was in the tail section. So proportionally, there would be a lot less explosive and a lot more steel than an ordinary contact bomb.
But when the bomb is already into the vitals of the target, you don't need as much boom anyway.
