The United States ... will provide pre-launch notification of commercial and National Aeronautics and Space Administration (NASA) space launches as well as the majority of intercontinental ballistic and submarine-launched ballistic missile launches.

Yes. The Soviets were even notified, shortly before the launch, of the Minuteman III ICBM I helped launch out at Vandenberg AFB back in the 80s.

Even then we had to hold for quite some time because a Soviet trawler and a sub were spotted in the downrange safety corridor and had to be chased out.
