The future USS Rafael Peralta (DDG-115) successfully completed alpha trials October 18, after spending two days underway off the coast of Maine. The trials were conducted by shipbuilder, General Dynamics’ Bath Iron Works (BIW).
Alpha trials, the initial set of builder’s trials, is the first of three underway periods that the ship will conduct to test and demonstrate that ship systems are properly installed and operational. Rafael Peralta successfully conducted a series of test events to demonstrate the operational capability of key communication, damage control, navigation and propulsion systems.
«Rafael Peralta is the first Arleigh Burke destroyer that BIW has taken to sea since the program was restarted in 2010», said Captain Casey Moton, DDG-51 class program manager, Program Executive Office (PEO) Ships. «The ship performed tremendously well, and that’s a testament to the hard work and commitment of our Navy team and industry partners».
Rafael Peralta is equipped with the Aegis Baseline 9 Combat System which includes an Integrated Air and Missile Defense (IAMD) capability incorporating Ballistic Missile Defense 5.0 Capability Upgrade and Naval Integrated Fire Control-Counter Air. The ship’s IAMD radar will provide increased computing power and radar upgrades that improve detection and reaction capabilities against modern air warfare threats. The Aegis Combat System will enable the ship to link radars with other ships and aircraft to provide a composite picture of the battle space and effectively increase the theater space.
USS Rafael Peralta (DDG-115) is the 65th Arleigh Burke (DDG-51) class destroyer and the first of the DDG-51 Flight IIA restart ships to be built at BIW. The shipyard is currently in production on future destroyers USS Thomas Hudner (DDG-116), USS Daniel Inouye (DDG-118) and USS Carl M. Levin (DDG-120) and under contract for three additional ships awarded as part of the five-ship multi-year procurement for fiscal years 2013-2017.
As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and boats and craft.
