The book presents a comprehensive history and analysis of the aircraft carrier and the Fresnel Lens Optical Landing System (FLOLS). It compares landing systems used in most aircraft carriers from the 20th century. The future of the aircraft landing systems also forms the basis of the book to compare different carrier technologies and evaluate the types of aircraft carriers, their development and future expectations in relation to technological changes.
