  1. Because one airplane could take out the ammo supply for hundreds of guns at once.

  2. Western GPS guidance is actually INS with GPS updates. Jamming only makes them use INS which is why you still see HIMARS makings good hits. Consumer grade drones do get jammed which forces recon to use landmarks for navigation but the weapons are jam resistant by ignoring the GPS system and defaulting to internal guidance.

  3.  @samoldfield5220  INS loses accuracy based on time. If an artillery shell or rocket/missile is moving at supersonic or near supersonic speeds, it will spend only seconds inside jamming range. INS usually has a drift of 650 meters over one hour. Shells do not spend an hour inside jammer range. They come down at lighting fast speeds. In 2012 the US military actually found a way to reduce INS drift by two thirds.

  4. Since they have less shells, they have to make them count.

  5.  @samoldfield5220  No, I am not talking about submarines. INS guidance inaccuracy comes from drift. That's why GPS guided munitions in the West are actually INS guided munitions with continuous GPS correction to account for drift. If you jam the GPS, the munition spends a grand total of a fraction of a second inside jammer range. The modern battlefield is full of GPS jammers because it hinders commercial quadcopter operation. It's simple as that.
