RIN 2120-AA66


Proposed Establishment of and Modification to Restricted Areas; 
Fort Sill, OK

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: This action proposes to establish 2 new restricted areas (R-
5601G and R-5601H) to expand the special use airspace (SUA) complex 
located at Fort Sill, OK, to provide additional maneuvering airspace 
for current and planned training activities determined to be hazardous 
to non-participating aircraft. Specifically, the proposed restricted 
areas would provide participating fighter or bomber aircraft with 
laser-firing and maneuvering airspace when training at the Falcon 
Bombing Range contained in R-5601C, at the West Range Target Area 
contained in R-5601B, or at the East Range Target Area contained in R-
5601A. In addition, the using agency for all Fort Sill restricted areas 
would be updated to reflect the current organization tasked with that 
responsibility. The U.S. Army requested that the FAA take this action 
to allow realistic training on current tactics developed and refined 
during recent combat operations for employing hazardous targeting laser 
systems and weapons capabilities at longer ranges from the target area.

DATES: Comments must be received on or before December 3, 2015.

ADDRESSES: Send comments on this proposal to the U.S. Department of

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking

    The FAA's authority to issue rules regarding aviation safety is 
found in Title 49 of the United States Code. Subtitle I, Section 106 
describes the authority of the FAA Administrator. Subtitle VII, 
Aviation Programs, describes in more detail the scope of the agency's 
authority.
    This rulemaking is promulgated under the authority described in 
Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the 
FAA is charged with prescribing regulations to assign the use of the 
airspace necessary to ensure the safety of aircraft and the efficient 
use of airspace. This regulation is within the scope of that authority 
as it would restructure the restricted airspace at Fort Sill, OK, to 
enhance safety and accommodate essential military training.

Background

    Military use of the airspace at Fort Sill, OK, can be traced back 
to 1949. Today, the Fort Sill SUA complex consists of six restricted 
areas, designated R-5601A, R-5601B, R-5601C, R-5601D, R-5601E, and R-
5601F. The three ranges (Falcon Range, West Range, and East Range) 
contained within the Fort Sill SUA complex are used for a wide variety 
of military air and ground activities; including, but not limited to, 
air-to-surface weapons delivery training, laser systems, artillery, and 
joint air and ground forces exercises. Weapons events include high-, 
medium-, and low-altitude bombing runs, to include level, climbing, and 
diving deliveries. Today, real-world combat tactics for employing 
targeting lasers and weapons systems at distances farther from the 
target are driving the requirement for increased lateral dimensions of 
the Fort Sill SUA complex to support aircrew training in laser 
employment and weapons delivery tactics. Although the R-5601A, R-5601B, 
R-5601C, and R-5601F airspace areas extend to a maximum altitude of 
40,000 feet mean sea level (MSL), the relatively small north to south 
dimensions of the restricted areas (approximately 9 nautical miles (NM) 
at its widest point) is not sufficient to provide the required distance 
from targets needed by aircrews employing current combat laser 
targeting or weapons deliveries tactics. Since there is no alternative 
SUA complex within 200 NM where combat lasers may be employed, aircrew 
training is significantly restricted at the Fort Sill ranges.

The Proposal

    The FAA is proposing an amendment to 14 CFR part 73 to establish 2 
new restricted areas (designated R-5601G and R-5601H) at Fort Sill, OK. 
This action would establish restricted area R-5601G with a ceiling to, 
but not including, 8,000 feet MSL under the Washita Military Operations 
Area (MOA), and establish restricted area R-5601H with a ceiling of 
Flight Level (FL) 400 to match the adjacent restricted areas; thus, 
expanding the lateral limits of restricted area airspace at the Fort 
Sill SUA complex. Restricted area R-5601G would abut the existing 
restricted area complex to the north, underlying the Washita MOA, and 
extend from 500 feet above ground level (AGL) to, but not including, 
8,000 feet MSL. R-5601G would extend approximately three quarters of 
the existing restricted area complex northward, between 5 NM to 11 NM, 
to provide the required expanded lateral space from the current range 
boundaries. Restricted area R-5601H would extend from the surface to 
FL400. R-5601H would fill a small airspace area surrounded by two 
continuously active restricted areas (R-5601A and R-5601B) extending 
from the surface to FL400 and a MOA extending from 8,000 feet MSL to, 
but not including, FL180. Additionally, when active, R-5601H would 
overlay the Fort Sill post and a portion of the Class D airspace 
supporting the non-joint use military airfield located at Fort Sill.
    The two new restricted areas would allow participating aircraft to 
maneuver within the current Fort Sill Approach Control Airspace and 
contain the hazardous combat laser energy (not eye-safe) within 
restricted airspace. As proposed, R-5601G would only be used for 
aircraft maneuvering and combat laser targeting employment and R-5601H 
would only be used for aircraft conducting Close Air Support (CAS) 
training. There would be no changes to

[[Page 63155]]

the existing pattern of firing, ordnance delivery runs, or weapons 
impact areas and all weapons release would continue to occur in R-
5601A, R-5601B, or R-5601C, as they are now. Additionally, no 
supersonic flight will occur.
    In addition to the proposed establishment of R-5601G and R-5601H, 
the following minor changes to the descriptions of the six existing 
Fort Sill restricted areas would be made. The using agency for R-5601A-
E would be changed from ``U.S. Army, Commanding General, Fort Sill, 
OK,'' to ``U.S. Army, Commanding General, U.S. Army Fires Center of 
Excellence (USAFCOE), Fort Sill, OK.'' The using agency for R-5601F 
would be changed from ``Commanding General, United States Army Field 
Artillery Center (USAFACFS), Fort Sill, OK,'' to ``U.S. Army, 
Commanding General, U.S. Army Fires Center of Excellence (USAFCOE), 
Fort Sill, OK.'' This change would reflect the current organizational 
responsibilities. The new using agency would also apply to the proposed 
R-5601G and R-5601H. The boundaries, designated altitudes, times of 
designation, and controlling agency information for restricted areas R-
5601A-F would not be changed by this proposal.
    The FAA does not anticipate any aeronautical impacts as a result of 
this proposed action since Fort Sill Approach Control has radar 
coverage over the proposed restricted areas and already controls the 
airspace from surface to 7,000 feet MSL. Procedures will be established 
to continue allowing non-participating aircraft access to the airspace 
even when the restricted areas are in use. Pilots seeking information 
about the activity status of R-5601G and R-5601H should contact Fort 
Sill Approach Control on the frequency listed in the ``Special Use 
Airspace'' panel of the Dallas--Ft. Worth Sectional Aeronautical Chart. 
Fort Sill Approach Control will continue to provide VFR traffic 
advisories, as they do today, to non-participating aircraft requesting 
them.

Regulatory Notices and Analyses

    The FAA has determined that this proposed regulation only involves 
an established body of technical regulations for which frequent and 
routine amendments are necessary to keep them operationally current. 
It, therefore: (1) Is not a ``significant regulatory action'' under 
Executive Order 12866; (2) is not a ``significant rule'' under 
Department of Transportation (DOT) Regulatory Policies and Procedures 
(44 FR 11034; February 26, 1979); and (3) does not warrant preparation 
of a regulatory evaluation as the anticipated impact is so minimal.
    Since this is a routine matter that will only affect air traffic 
procedures and air navigation, it is certified that this proposed rule, 
when promulgated, will not have a significant economic impact on a 
substantial number of small entities under the criteria of the 
Regulatory Flexibility Act.

Environmental Review

    This proposal will be subjected to an environmental analysis in 
accordance with FAA Order 1050.1E, ``Environmental Impacts: Policies 
and Procedures,'' prior to any FAA final regulatory action.
