First published in 1900, the Weyer has gained recognition as an international standard work for decades. Its relevance, the accuracy of the sketches, and clarity are proverbial. The 69th edition also offers an extensive amount of information about all navies of the world in a compact format. The fleet lists, uniformly presented in genera and subgenera, can be used not only for reference but also for comparing individual ships. The wealth of specific information on ships and classes includes, among other data: number and type, name and identification, water displacement, dimensions, speed, engines/boilers, performance, range, armor, electronics, armament, missiles, aircraft, radar and sonar systems, as well as information on electrical installations. It provides a comprehensive overview of the ships, vehicles, and aircraft of all navies. The Weyer is the fleet handbook for both professionals and interested laypersons.
