The Navy has installed their prototype railgun on a 1500 ton military catamaran called the joint high speed vessel aka JHSV. Lance M. Bacon reports this development at the Navy Times and Sam LaGrone at UNSI.
The JHSV has 600 tons of excess payload capacity, but Zumwalt Navy destroyers have 20 tons of excess payload capacity. The railgun will need to be made more compact to be installed on the destroyers. The Destroyers at 14500 tons are bigger than the JHSV. The Destroyers are already filled with other systems.
The railgun also uses 34 mega joules of power to launch a 23-pound projectile to distances greater than 100 miles at speeds topping Mach 7 (better than 5,300 mph). While Zumwalt-class destroyers will generate roughly 78 mega joules (twice the power the railgun needs), most destroyers have in reserve less than one-third of the power the railgun needs. And there are a whole bunch of limitations on what can be done inside the ship to add power generators. Developers will house power generators in con-ex boxes during the JHSV demonstration, but a permanent power solution will be needed before the railgun lands in the fleet.
Aegis is a fully integrated combat system on cruisers and destroyers, and the railgun's fire control loop doesn't yet know how to talk to that system. Railgun fire control will need Aegis integration.
The target is 2018 for installation of a combat railgun on a US Navy destroyer.
Engineering studies to include an electromagnetic railgun on a Zumwalt-class destroyer (DDG-1000) have started at Naval Sea Systems Command, NAVSEA’s head said Thursday.
The work will do the math to determine if the Zumwalt-class will have the space, power and cooling to field a railgun – likely replacing one of the two 155mm BAE Advanced Gun Systems (AGS) ahead of the ship’s deck house.
The likely candidate for the weapon would be the third planned Zumwalt, Lyndon B. Johnson (DDG-1002) currently under construction at General Dynamics Bath Iron Works (BIW) with an expected delivery date of 2018.
