Many hands make light work, well-equipped, the strongest company had already been temporarily contracted by Hu Anbiao for a high price.
However...
Replicating a nuclear warhead is not that easy.
Shape, size, weight, actually, all of these are manageable.
Bent steel plates, cutting, welding, polishing, painting...the exterior can be made to look identical.
As for the weight, that's even simpler. If the real warhead weighs three hundred kilograms, just stuff things like steel ingots inside the fake one.
The real challenge is the extremely special password device on the actual nuclear warhead.
This device is embedded in the missile body, and after lifting the pressure-resistant casing, there is a control panel similar to an old-fashioned calculator with buttons labeled in English for different functions.
And this control panel uses a classic PLC control circuit.
