## Abstract

This action amends the designated altitudes and times of use for Restricted Area R-2306C (R-2306C), Yuma West, AZ. This action would raise the upper altitude of R-2306C from 17,000 feet mean seal level (MSL) to 40,000 feet MSL. This action also reduces the time of use from continuous, to 0600 to 2200 hours daily local time, other times by NOTAM. The U.S. Army requested the modification to better accommodate existing and future testing requirements at the Yuma Proving Ground, AZ. This modification does not alter the current lateral boundaries or activities conducted in R-2306C.
