Its extreme structural simplicity, forgiving flight behaviour, and near-indestructible wooden airframe made it the backbone of Soviet pilot training and, in wartime, one of the most effective low-level night harassment bombers of World War II.\u003c\/p\u003e\n\u003cp\u003eThis collection brings together original Soviet factory and military publications spanning 1937–1951, covering the U-2, U-2VS, U-2S, and Po-2 variants across their full operational life.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eDocument Manifest — 7 Original Soviet Publications\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eСамолет У-2\u003c\/strong\u003e — Aircraft U-2\u003cbr\u003eAuthor: N.
