the Navy's new Columbia class missile submarine a stealth killer while the Columbia class is intended to replace the existing fleet of ohio-class ballistic. Missile submarines the new boats include a number of not yet seen technologies as well as. Different configurations when compared with the ohio-class the Columbia. Class will have 16 launch tubes rather than the 20 tubes current on Ohio boats yet the Columbia's will also be about two tons larger according to Navy information the Navy has now issued at least one-fourth of the design work and begun further advancing work on systems such as a. Stealthy electric drive propulsion system for the emerging nuclear-armed Columbia class ballistic missile submarines by 2021 of the required design disclosures drawings 26% have been issued and the program is on a path to of 83% issued by construction start bill. Couch spokesman for Naval Sea Systems Command told warrior maven the Columbia classes to be equipped with an electric drive propulsion train as opposed to the mechanical drive propulsion train. Used on other Navy submarines in today's ohio-class submarines a reactor plant generates heat which creates steam Navy officials explain the steam men turns turbines which produce electricity and also propel the ship forward through reduction gears which are able to translate the high-speed energy from a turbine into the. Shaft RPMs needed to move in both propeller the electric drive system is expected to be quieter that. Is stealthier than a mechanical drive system a Congressional Research Service report on Columbia class submarines from earlier this year. States designed to be 560 feet long and housed 16 tried and on ID five missiles fired from 44 foot long missile tubes Columbia class submarines will use a quieting X shaped Stern configuration the X shaped Stern will restore maneuverability to. Submarines as submarine designs progressed from using a propeller to using a propulsor to improve quieting submarines lost some surface maneuverability Navy officials explained Navy developers explained. An electric drive. Propulsion technology still relies on a nuclear reactor to generate heat and create steam to power turbines however the electricity produced is transferred to an electric motor. Rather than so-called reduction gears to spin the boats propellers the use of an electric motor brings other advantages as well according to an MIT essay written years ago when electric drive was being evaluated for submarine propulsion using an electric motor optimizes use of installed reactor power in a more efficient way. Compared with mechanical drive submarines making more on-board power available for other uses according to an essay called evaluation and comparison of electric propulsion motors for submarines author Joel Harbor says that on mechanical drive submarine 80% of the total reactor power is used exclusively for. Propulsion with submarine the installed reactor power of the submarine is first converted into electrical power and then delivered to an electric propulsion motor the now available electrical potential not being used for propulsion could easily be tapped into for other uses he writes research Science. And Technology work an initial missile tube construction has been underway for several years one key exercise called tube and how foraging involves building four packs of missile tubes to assess welding and construction methods these structures are intended to load into the boats modules as construction advances. Early procurement of the missile tubes and prototyping of the first assembly of four missile tubes are supporting the proving out to production planning couch said while the Columbia class is intended to replace the existing fleet. Of ohio-class ballistic class will have 16 launch tubes rather than the 20 tubes current on Ohio boats yet the Columbia's will also be about two tons larger according to Navy information to Columbia class to be operational by the 2028 is a new generation of technically advanced submarines intended to quietly patrol the undersea realm around the world to ensure second-strike. Ability should the u.s. be hit with the catastrophic nuclear attack formal production is scheduled for 2021 as a key step toward fielding of a new generation of nuclear armed submarines to serve all the. Way into and beyond the 2080s General Dynamics an electric bolt has begun acquiring long lead items and anticipation of beginning construction the process involves acquiring metals electronics sonar arrays and other key components necessary to build the submarines both the Pentagon in the Navy are approaching this program with the sense of urgency given the escalation of the current. Global threat environment many senior dot officials. Have called the Columbia class program as a number one priority across all the services the Columbia class submarine program is leveraging enhanced acquisition authorities provided by Congress such as advanced procurement advanced construction and multi-year continuous production of missile tubes couch added .
