This book summarizes current understanding of the scientific, clinical, and technical issues surrounding the use of contact lenses. It discusses the special occupational conditions experienced by military personnel, particularly in extreme environments, that give rise to the question of whether or not to use contact lenses. Experts in optometry, ophthalmology, visual psychophysics, and engineering describe recent developments in design and use; and representatives of the military services provide examples of actual situations in aerospace settings. Considerations in Contact Lens Use Under Adverse Conditions will be of particular interest to those involved in the design of contact lenses and those responsible for occupational safety and health matters in the private sector.

Naval Aviation is a warfighting force. Its capabilities and capacity have been sharply honed and are fundamental to achieving the goals of the Defense Strategic Guidance, Sustaining U.S. Global Leadership: Priorities for 21st-Century Defense. The fiscal landscape and emerging security environment are unstable and uncertain; balancing budgetary challenges and the need for national defense demand that Naval Aviation fulfill more global commitments while operating within tighter budget limitations. This document, guided by and aligned to The Vision for Naval Aviation 2025 and its pillars of capability superiority, wholeness, and maintaining capacity, provides our unified view of how Naval Aviation intends to meet the challenges ahead. We will do it through revolutionary changes in capabilities, retaining our aggregate and operational capacity, and by safely, effectively, and affordably executing our job of organizing, manning, training, and equipping fleet combat forces. Naval Aviation is a warfighting enterprise that continues to be the preeminent forward-deployed force ready to fulfill any mission assigned. Our aircraft carriers, amphibious assault ships, carrier air wings, aviation combat elements, and maritime patrol and reconnaissance forces maintain a combat-ready posture as an instrument of our nation's will. For the past century, Naval Aviation has been at the forefront of operational and tactical innovation. Consistent with The Vision for Naval Aviation 2025, we remain focused on systematically establishing an enduring, affordable, lethal, and adaptable approach to meet and shape strategic objectives. We will continue to operate forward with revolutionary Integrated and Interoperable capabilities designed to face future threats in an increasingly-contested operating environment. Our nation's demand for access, commerce, and maneuver will require us to continue to evolve capabilities and capacities to assure our nation's and Navy's global leadership from the sea. Naval Aviation is a major stakeholder in these operations, and will continue to play key roles in the rebalancing of our nation's global posture and presence to an emphasis on the Pacific and sustaining support for our partners in the Middle East. This vision for Naval Aviation aspires to ensure an affordable, powerful Navy that maintains our core competencies across the spectrum of military operations. Our Sailors and Marines embrace the privilege of this awesome responsibility with pride, determination, and enthusiasm.

Top Gun was only part of the story. Fly Navy delves beyond the Hollywood image to reveal the true mettle and genuine story of the elite men and women of naval aviation. For one hundred years, the U.S. Navy's aviators and crews have made the difference on military and peacetime missions around the world. Their unparalleled skill, preparation, and everyday dedication have paid off when it matters most: when lives are on the line. Together, these men and women—officers and enlisted personnel, past and present—have protected freedom, served their country, and forged a legacy of valor like no other. In this landmark book, Alvin Townley takes readers on an adventure around the world and across generations as he goes behind the scenes of naval aviation. From the skies over the Arabian Sea to the jungles of Southeast Asia to carriers patrolling the vast Pacific, he uncovers incredible stories of service members who survived weeks adrift at sea, made midnight rescues in deadly storms, crash-landed behind enemy lines, and found themselves in situations where their exceptional training and focus were the only things standing between life and death. Filled with inspiring personal accounts of courage, camaraderie, and sheer perseverance, Fly Navy pays tribute to the extraordinary individuals who have built naval aviation into the revered force it is today—and will remain tomorrow.

The ability of the United States Air Force (USAF) to keep its aircraft operating at an acceptable operational tempo, in wartime and in peacetime, has been important to the Air Force since its inception. This is a much larger issue for the Air Force today, having effectively been at war for 20 years, with its aircraft becoming increasingly more expensive to operate and maintain and with military budgets certain to further decrease. The enormously complex Air Force weapon system sustainment enterprise is currently constrained on many sides by laws, policies, regulations and procedures, relationships, and organizational issues emanating from Congress, the Department of Defense (DoD), and the Air Force itself. Against the back-drop of these stark realities, the Air Force requested the National Research Council (NRC) of the National Academies, under the auspices of the Air Force Studies Board to conduct and in-depth assessment of current and future Air Force weapon system sustainment initiatives and recommended future courses of action for consideration by the Air Force. Examination of the U.S. Air Force's Aircraft Sustainment Needs in the Future and Its Strategy to Meet Those Needs addresses the following topics: Assess current sustainment investments, infrastructure, and processes for adequacy in sustaining aging legacy systems and their support equipment. Determine if any modifications in policy are required and, if so, identify them and make recommendations for changes in Air Force regulations, policies, and strategies to accomplish the sustainment goals of the Air Force. Determine if any modifications in technology efforts are required and, if so, identify them and make recommendations regarding the technology efforts that should be pursued because they could make positive impacts on the sustainment of the current and future systems and equipment of the Air Force. Determine if the Air Logistics Centers have the necessary resources (funding, manpower, skill sets, and technologies) and are equipped and organized to sustain legacy systems and equipment and the Air Force of tomorrow. Identify and make recommendations regarding incorporating sustainability into future aircraft designs.

Naval Aviation forces are forward, engaged and ready-every day. Expeditionary forces, amphibious forces, nuclear-powered aircraft carriers, air wings, manned and unmanned platforms, rotary- and fixed-wing aircraft are on station, valued and in increasingly higher demand. No other service or community can deliver the capabilities Naval Aviation brings in support of our national interests. It is a national priority to sustain, resource and ultimately expand these capabilities to ensure that when called, Naval Aviation is at the hold short, takeoff checks complete... Ready to Go. This publication is part of the roadmap to ensuring Naval Aviation possesses the readiness, capabilities and capacity to deliver on the five essential functions outlined in the maritime strategy-All Domain Access, Deterrence, Sea Control, Power Projection and Maritime Security-are missions that depend upon Naval Aviation to guarantee their success. It is essential that our vision fully supports and aligns to this cooperative strategy.
