Development
Development began in 1958, with the technical evaluation being completed in 1963. That year, the US Navy received the first rounds and soon reached Initial Operation Capability (IOC) aboard the attack submarine Permit. When SUBROC reached IOC The US Navy's admiral in charge of weapons procurement stated that SUBROC was " .. a more difficult technical problem than Polaris." SUBROC was never used in combat, and all were decommissioned following the end of the Cold War in 1989. Because the nuclear warhead was an integral part of the weapon, SUBROC could not be exported to other navies, and there is no evidence that any were supplied to other NATO allies under the well-established arrangements for supplying other dual-key nuclear weapons. Towards the end of the 1970s, a planned successor, the UUM-125 Sea Lance, was frequently delayed due to funding problems and eventually canceled.

Famous quotes containing the word development:
“Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.”
—Sara Lawrence Lightfoot (20th century)
“I hope I may claim in the present work to have made it probable that the laws of arithmetic are analytic judgments and consequently a priori. Arithmetic thus becomes simply a development of logic, and every proposition of arithmetic a law of logic, albeit a derivative one. To apply arithmetic in the physical sciences is to bring logic to bear on observed facts; calculation becomes deduction.”
—Gottlob Frege (1848–1925)
“The highest form of development is to govern one’s self.”
—Zerelda G. Wallace (1817–1901)
