NASMOD - Quantifying the Impacts of Encroachment

NASMOD quantifying the impact of windfarms encroachment on military training

Valuable tool for developing defensible cost and impact on military training

Growth of urban areas, other development, and construction of land and offshore energy infrastructure has gradually reduced the isolation and safety buffers of critical military training resources and has a detrimental impact on the ability of the military to successfully complete training.

NASMOD is a valuable and proven tool for documenting detailed impacts on training:

    • Quantify the impacts of encroachment in terms of training lost, relocated, or delayed
    • Identify specific mission area and readiness level impacts
    • Defensibly calculate cost of training relocation or other mitigation
    • Determine military environment impact (EIS)

Windmill Farm Proposals near Navy Basic Jet Pilot Training Base Study

Recently, several windmill electric generation farms were proposed in the vicinity of NAS Kingsville, Texas. The U.S. Navy, concerned that air and ground-based radar and other electronic aids to air navigation have been shown to be degraded by windmill operation, used NASMOD to document the impacts on Naval Aviator basic jet training.

An existing NASMOD Model of the South Texas region was modified using a set of assumptions including the loss or degradation of local Airport Surveillance Radar, Precision Approach Radar, and Instrument Landing Systems on specific training syllabi missions. Alternative local training sites, training detachments triggered at certain training backlog points, and weather impacts all were included in the model. Several one-year simulations were then run assuming 100% degradation of the ground-based air navigation systems as well as various levels of lesser degradation.

Simulation results were compared back to the existing Baseline Model and shown to have significant impacts at nearly all levels of degradation.  The simulation identified the specific impact on student pilot throughput, which missions were subject to impact, what times of the year the impact was most severe, and calculated the cost to the Navy for mission re-routing and required extra training detachments out of the area due to the local training loss. The documented results were then available for use as ammunition to negotiate with authorities in order to mitigate these impacts and reduce future potential costs.

As a resourced-based and military training-centric simulation model, NASMOD has proven to be an ideal tool for defensible analysis and documentation of the impacts of encroachment and for protecting vital air, land and seaspace training resources. NASMOD provides planning and analysis expertise in support of the development of Air and Range Installation Compatible Use Zone Studies (AICUZ and RAICUZ) as well as Joint Land Use Study (JLUS).
