Frank Kendall, Pentagon Under Secretary for Defense for Acquisition, Technology and Logistics, signed off on a $125 billion purchase of twelve sophisticated, nuclear-capable submarines. Kendall said he hoped to have the project done before he left.
|In late 2016, a continuing resolution authorized the use of $773 million to be spent on the program. The Columbia-class ballistic missile submarines are to begin construction in 2021. The submarines use several propulsion mechanisms, that include nuclear power, turbo-electric drive and a pump-jet. They can be equipped with 16 Trident DS submarine-launched ballistic missiles. The missiles are said to be able to achieve nuclear deterrence with fewer submarines and are almost as accurate as land-based missiles. Submarines are a vital part of the top-priority US Navy weapons program.|
