(1:144) Fx 1400 Fritz X

Fritz X was the most common name for a German guided anti-ship glide bomb used during World War II. Fritz X was the world's first precision guided weapon deployed in combat and the first to sink a ship in combat. Fritz X was a nickname used both by Allied and Luftwaffe personnel. Alternative names include Ruhrstahl SD 1400 X, Kramer X-1, PC 1400X or FX 1400 (the latter, along with the unguided PC 1400 Fritz nickname, is the origin for the name "Fritz X"). Along with the United States Army Air Forces (USAAF) similar Azon weapon of the same period, it is one of the forerunners of modern anti-ship missiles and precision-guided weapons.
