My understanding is that it wasn't done in a single shot, this is a multi year long project. The weapon isn't a single satellite but is like four or five that either were put together later or have some kind of interlocking function. (Think like a rifle that assembles itself.) The ammunition itself is telescoping and permits a hollow core that can be filled either with a liquid or gas. Once the needle is extended to full size it is so precisely machined that the seams are invisible and also it cannot be returned to original size. I don't recall the material but some kind of tungsten alloy sounds right.
