With its huge, white partially-folding delta wing, its fuselage resembling a striking cobra and its extraordinary performance, it was one of the foremost technological achievements of the 20th century. A strategic bomber built to outrun any Soviet fighter jet, it could reach Mach 3 with a full nuclear payload - as fast as the legendary SR-71 Blackbird but more than three times the size. However, its role as a nuclear bomber was limited after the introduction of Intercontinental Ballistic Missiles, and defence cuts eventually led to the project being scrapped in the mid-1960s. The Valkyrie had a brief, costly decade of life but it proved the continuing value of developing manned bombers. However, almost half a century after the XB-70 its predecessor, the B-52, continues in service. Using full colour artwork and rigorous analysis, this is the complete story of the ultimate US Cold War military X-plane.","brand":"Bloomsbury USA","offers":[{"title":"Default Title","offer_id":53579969167702,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"url":"https:\/\/www.momoxbooks.com\/products\/davies-e-peter-north-american-xb-70-valkyrie-9781472825032","provider":"momoxbooks","version":"1.0","type":"link"}
