In this new book of the Italian Aviation Series, you will learn about the birth and development of the UH-1N, a twin-engine helicopter, starting from the UH-1D single-engine version. The UH-1N was built in Italy by Agusta, assuming the abbreviation AB 212, which developed the ASW version, used by Naval Aviation (the Navy has always used an electronic warfare version called "Owl"). The Air Force used the AB 212 in the various Link Squadrons, upgrading it to the ICO standard and using it in combat in Afghanistan. The Army is the armed force that has received the lowest number of units, but which uses the AB 212 with satisfaction in foreign missions, such as the ITALIR contingent present in Lebanon for over 40 years. The AB 212 helicopter is still in service with Naval Aviation, the Air Force, and Army Aviation. All this and much more are described in a compelling book that fills an important gap. A book full of images, most of them unpublished, this story cannot be missing from the library of any aviation enthusiast.
