This requirement is to provide Static Transfer Switches (STS) at any applicable National Airspace Systems (NAS) facilities located throughout the United States and its territories. 

The Federal Aviation Administration is currently acquiring Commercial Off-The-Shelf/Non-Developmental Items (COTS/NDI) Static Transfer Switches. This COTS/NDI approach provides the FAA with the most efficient approach to acquire Static Transfer Switches. The STS functions as a selector between two sources of power to critical equipment.

This Statement of Work (SOW) defines the requirements for project management, configuration management, technical support services, test and evaluation, logistics support, training, and quality control for the STS and associated equipment being acquired. The Contractor must provide all necessary equipment; engineering; logistics support; maintenance/operator training; spares provisioning and maintenance program; and provide the documentation to support the acquisition of the STS and associated equipment.
