Development
To facilitate development of the long-range SM-64 Navaho surface-to-surface cruise missile, North American Aviation developed the RTV-A-5, or X-10 in 1951. This vehicle was to prove out critical flight technology for the design of the cruise vehicle of the Navaho missile design. These included proving the basic aerodynamics out to Mach 2, flight testing the inertial guidance unit and flight control avionics to the same speed, and finally validate the recovery system for the next phase in the Navaho program. Preliminary design of the X-10 was completed in February 1951 and the first vehicle was delivered to Edwards Air Force Base in May 1953. The first flight occurred on October 14, 1953.
The X-10 was powered by two Westinghouse J40 turbojet engines with afterburners, and equipped with landing gear for conventional take off and landing. The combination of a delta wing with an all-moving canard gave it extremely good aerodynamics in the trans-sonic and supersonic environments. It also made the vehicle unstable requiring active computer flight control in the form of an autopilot. Thus, the X-10 is similar to modern military fighters which are flown by the onboard computer and not directly by the pilot. In this same regard, though the X-10 was receiving directional commands from a radio-command guidance system, these commands were sent through the on-board computer which in turn implemented the commands. Later X-10s included an N-6 inertial navigation system which completely controlled the vehicle through the cruise portion of the flight.

Famous quotes containing the word development:
“As a final instance of the force of limitations in the development of concentration, I must mention that beautiful creature, Helen Keller, whom I have known for these many years. I am filled with wonder of her knowledge, acquired because shut out from all distraction. If I could have been deaf, dumb, and blind I also might have arrived at something.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.”
—Henry David Thoreau (1817–1862)
“... work is only part of a man’s life; play, family, church, individual and group contacts, educational opportunities, the intelligent exercise of citizenship, all play a part in a well-rounded life. Workers are men and women with potentialities for mental and spiritual development as well as for physical health. We are paying the price today of having too long sidestepped all that this means to the mental, moral, and spiritual health of our nation.”
—Mary Barnett Gilson (1877–?)
