Someone out there more familiar with ICBM’s please correct me.
But, before the age of GPS, wasn’t the missile guided by stars? I heard that once. Which made their accuracy about a mile from the target, which was why we needed so many warheads and missiles.
Regardless, if the jammers reduce accuracy, the missile will still get there and the fallout alone will create havoc.
Also, in obama’s first term it was his goal to reduce our nuclear stockpile. My understanding now, is they are updating the delivery methods and not will not reduce inventory. Right?
I think even now GPS can be used to get a fix, then inertial guidance can be used.

They use inertial guidance systems that use spinning gyroscopes that hold their position in respect to the center of the earths gravity at the point of launch, then the guidance system’s computer senses the gyroscopes motion/rotation as the missile travels across the earth guiding the missile to its target. The technology has so improved that a strike within feet of the target is now achievable. Our current ICBM’s and cruise missiles still use it. It’s impervious to outside interference, so if the GPS system is disrupted, inertial guidance as well as other backup systems should be able to take over and guide the missile successfully to its target.
Inertial guidance on-board has a CEP way less than a mile, maybe end-zone to end-zone on the old stuff. Big yields were to compensate for targeting errors on subterranean facilities.
Lacking GPS, the solution (for the aggressor), would be to send more or bigger bombs.
