Development
Trident I (designated C4) was deployed in 1979 and retired in 2005. Its objective was to achieve performance similar to Poseidon (C3) but at extended range which improved survivability of the submarine. Trident II (designated D5) had the objective of improved accuracy, and was first deployed in 1990, and was planned to be in service for the thirty-year life of the submarines, until 2027.
Trident missiles are provided to the United Kingdom under the terms of the 1963 Polaris Sales Agreement which was modified in 1982 for Trident. British Prime Minister Margaret Thatcher wrote to President Carter on July 10, 1980, to request that he approve supply of Trident I missiles. However, in 1982 Thatcher wrote to President Reagan to request the United Kingdom be allowed to procure the Trident II system, the procurement of which had been accelerated by the US Navy. This was agreed in March 1982. Under the agreement, the United Kingdom made a 5% research and development contribution.

Famous quotes containing the word development:
“And then ... he flung open the door of my compartment, and ushered in Ma young and lovely lady! I muttered to myself with some bitterness. And this is, of course, the opening scene of Vol. I. She is the Heroine. And I am one of those subordinate characters that only turn up when needed for the development of her destiny, and whose final appearance is outside the church, waiting to greet the Happy Pair!”
—Lewis Carroll [Charles Lutwidge Dodgson] (18321898)
“The work of adult life is not easy. As in childhood, each step presents not only new tasks of development but requires a letting go of the techniques that worked before. With each passage some magic must be given up, some cherished illusion of safety and comfortably familiar sense of self must be cast off, to allow for the greater expansion of our distinctiveness.”
—Gail Sheehy (20th century)
“Fascism, the more it considers and observes the future and the development of humanity, quite apart from political considerations of the moment, believes neither in the possibility nor the utility of perpetual peace.”
—Benito Mussolini (18831945)
