aircraft for the U.S. Navy and NACA. A straight-wing aircraft,
the first of three Skystreak aircraft flew in 1947.
To continue research at higher speeds and
altitudes, the D-558-II Skyrocket was given swept-wings and a
rocket motor in addition to its turbojet. The first of three
Skyrocket aircraft flew in 1948. In 1953, a Skyrocket became
the first aircraft in the world to be flown at Mach 2. The
Skyrocket program lasted until 1956. |
