פטנטים של מדע מתקדם
להלן רשימת פטנטים סינים, רוסים ואמריקאים של כלים ושיטות הינע שיתכן והושגו באמצעות הנדסה לאחור של כלים חוצניים.
בדומה לכל כלי טיס קונבנציונלי בעל יכולות מיוחדות שפותח בעבר, כלים כאלו יכולים לשמש לאיסוף מודיעין ומשימות חשאיות מיוחדות, שהאינטרס הביטחוני מחייב לחסות אותן ואת היכולות המבצעיות. זו אחת הסיבות להסתרה בנושא הזה.
