Design and Development
The T-6 is a development of the Pilatus PC-9, modified significantly by Beechcraft in order to enter the Joint Primary Aircraft Training System (JPATS) competition in the 1990s. A similar arrangement between Pilatus and British Aerospace had also been in place for a Royal Air Force competition in the 1980s, although this competition selected the Short Tucano. The aircraft was designated under the 1962 United States Tri-Service aircraft designation system and named for the decades-earlier T-6 Texan.
The Beechcraft brand has since been purchased from Raytheon by Onex Corporation a Canadian "private equity fund" which retained the name Hawker Beechcraft.
The JPATS competition winning design was based on a commercial off the shelf Pilatus PC-9, with minor modifications. Additional requirements and conflicts between the Air Force and the Navy resulted in delays, cost increases (from initial estimates of $3.9 to roughly $6 million per aircraft) and a completely new aircraft that is 22% or 1,100 lbs heavier than the Pilatus.
On April 9, 2007 the U.S. Department of Defense released their Selected Acquisition Reports, which reported that the T-6 JPATS program was one of only eight programs cited for Congressional notification for 25-50% cost overrun over initial estimates, which is referred to as a "Nunn-McCurdy Breach" after the Nunn-McCurdy Amendment. It is unusual for a program so far into full rate production to experience significant enough cost overruns to trigger this Congressional notification.

Famous quotes containing the words design and/or development:
“If I knew for a certainty that a man was coming to my house with the conscious design of doing me good, I should run for my life ... for fear that I should get some of his good done to me,—some of its virus mingled with my blood.”
—Henry David Thoreau (1817–1862)
“For decades child development experts have erroneously directed parents to sing with one voice, a unison chorus of values, politics, disciplinary and loving styles. But duets have greater harmonic possibilities and are more interesting to listen to, so long as cacophony or dissonance remains at acceptable levels.”
—Kyle D. Pruett (20th century)
