Ingalls delivers aft peripheral vertical launch system

Huntington Ingalls Industries’ Ingalls Shipbuilding division has delivered the final aft peripheral vertical launch system (PVLS) assemblies to the U.S. Navy for the Zumwalt-class destroyer Michael Monsoor.

The PVLS distributes the missile launchers for the destroyer in separate four-cell launcher compartments along the ship’s hull. It is an alternative to the traditional centralized missile magazines found on DDG 51-class ships. The PVLS launcher configuration was chosen to significantly enhance the ship’s survivability. Four assembly units make up the aft PVLS. The first two units were delivered in July 2012.

General Dynamics’ Bath Iron Works is building the Michael Monsoor‘s hull, while Ingalls is building the PVLS assemblies in Pascagoula, Miss., and the composite hangar and deckhouse in Gulfport, Miss. The rest of Ingalls’ work for the Michael Monsoor is expected to be completed by the first quarter of 2014.
