834 Red Flag

In an era without GPS navigation, the accuracy of missiles could actually be made a little higher. However, such a device was quite expensive and was called the Celestial Navigation System.

This thing could, in the age without satellite positioning navigation, control the attack error of ballistic missiles within 200 meters, which could be called a miracle.

But the price of this thing was also "sky-high", so the cost of the missiles themselves also rose significantly.

Under normal circumstances, in order to reduce the cost of missiles, manufacturers would not equip insignificant missiles with this precise and expensive guidance system.

The Dongfeng series ballistic missiles of Tang Country, due to the rush of warfare progress, had previously not adopted this new system that was immature and had lagging development progress.

But now, everything had changed.
