The war in Ukraine has shown the US that expensive GPS-guided munitions are ineffective

The United States used to believe that any conflict could be won with expensive and precision weapons, but the war in Ukraine is forcing it to rethink its assumptions.

Here's What We Know

Stacey Pettijohn, director of the defence programme at the Centre for a New American Security, told The Washington Post that the Russian-Ukrainian war has forced a rethinking of the notion that precision weapons are the key to winning conflicts in the United States.

The Himars or Excalibur missiles, which are guided by GPS, have proven to be vulnerable to Russian electronic warfare. First of all, because they encode their signals and divert them from their course.

Pettijohn said the US has noted the fact that Ukraine mostly uses older artillery that is guided by sensors and drones.
