PROBLEM TO BE SOLVED: To provide single crystal nickel-based superalloy compositions, single crystal nickel-based superalloy components, and methods of fabricating such components. SOLUTION: Disclosed is a single crystal nickel-based superalloy composition consisting essentially of, in weight percent from about 3.8 to about 4.2 percent chromium, from about 10.0 to about 10.5 percent cobalt, from about 1.8 to about 2.2 percent molybdenum, from about 4.8 to about 5.2 percent tungsten, from about 5.8 to about 6.2 percent rhenium, from about 5.5 to about 5.8 percent aluminum, from about 5.8 to about 6.2 percent tantalum, from about 3.8 to about 4.2 percent ruthenium, from about 0.13 to about 0.17 percent hafnium, and a balance of nickel.
