The United States Air Force and the National Park Service share one fundamental mission: to defend, protect and preserve the United States. Both agencies work to ensure that the America we know today is the same nation we pass on to our children and grandchildren. National parks are the crown jewels set aside to look and sound today and tomorrow as they did generations ago. Accomplishing the objectives of the two agencies in the same space is a complex and challenging task. The Air Force must test its equipment and train its people to defend our nation; the National Park Service must continually serve, satisfy, and educate today's visitors while safeguarding the wildlife, natural, cultural, and historic assets for future generations. With 387 park units, an estimated 150 of which underlie training routes and other military airspace, some conflict between the two agencies is inevitable. Population growth and development around installations threatens to diminish the amount of airspace available for training. Similarly, many NPS soundscapes are being degraded by a variety of noise intrusions. Though a critical park resource, natural sound cannot be safeguarded in all places at all times. But where the potential for conflict can be identified, it can be managed, minimized, or entirely avoided.

The United States Air Force and National Park Service Western Pacific Regional Sourcebook is designed to facilitate better communication and local interaction between the National Park Service (NPS) and United States Air Force (USAF). The sourcebook was a cooperative effort developed by a task force of USAF and NPS officers, employees, and consultants, and advised by a focus group comprised of USAF officers and managers and NPS park superintendents, park staffs, and regional office officials.

The sourcebook builds on the progress made by the USAF Airspace and Range Council's regional conferences, which bring together all types of airspace users for discussion. The sourcebook provides a tool for the increased understanding of the NPS and USAF missions and priorities by providing information on each NPS unit and USAF installation within the region. Along with the contact information, mission and significance of each NPS unit and USAF installation, a map is included that cross-reference the boundary of the park, the major features and visitors services with underlying military airspace and the military uses of the airspace overlying the parks.
