Development
Development of the LY-60 was precipitated by the Chinese requirement for a beyond visual range (BVR) weapons system. Directly copying the AIM-7 proved unsuccessful, after which China purchased a number of Alenia Aspide missiles from Italy. Due to the urgent need of BVR air-to-air missile, PL-11 was given the priority. The very first batch of PL-11 was Chinese assembled Aspide using Italy supplied components, and it was accepted to Chinese service in the same year. However, hopes of locally manufacturing the missile under license collapsed after the Tiananmen Square crackdown of 1989.

Famous quotes containing the word development:
“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)
“The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.”
—Selma H. Fraiberg (20th century)
“Somehow we have been taught to believe that the experiences of girls and women are not important in the study and understanding of human behavior. If we know men, then we know all of humankind. These prevalent cultural attitudes totally deny the uniqueness of the female experience, limiting the development of girls and women and depriving a needy world of the gifts, talents, and resources our daughters have to offer.”
—Jeanne Elium (20th century)
