Modification to Restricted Area R-5601F and Establishment of Restricted Area R-5601J; Fort Sill, OK

This action amends the restricted areas at Fort Sill, OK, to subdivide R-5601F into two subareas, R-5601F and R-5601J, make a minor correction to one boundary point in R-5601G, and to update and standardize the using agency information for each restricted area in the Fort Sill restricted area complex. The FAA is taking this action to allow for more efficient use of the airspace during periods when military activities only require the eastern portions of the restricted area complex. The airspace modifications are fully contained within the existing lateral and vertical boundaries of the Fort Sill, OK, restricted airspace. The using agency information update to each of the restricted areas in the Fort Sill complex is editorial only.
