Portland's keel was laid down on 2 August 2013, at the Ingalls Shipbuilding yard in Pascagoula, Mississippi. The ship's sponsor is Bonnie Amos, wife of U.S. Marine Corps Commandant General James Amos.[2] Portland was launched on 13 February 2016,[1][3][4] and she was delivered to the Navy on 18 September 2017.[5] She was commissioned on 14 December 2017,[1] but her commissioning ceremony was not held until 21 April 2018, when she was in the city of Portland for the festivities.[6][7][8] The commissioning ceremony was protested by a number of local anti-war groups, who opposed a warship being named after the city.[3][9]

Laser weapon systemEdit

Laser Weapon System (LaWS)

The AN/SEQ-3 Laser Weapon System (LaWS) was moved from ex-USS Ponce to Portland for indefinite testing.[10] It was installed at the end of 2018.[11] In May 2020, USS Portland (LPD-27) successfully destroyed an unmanned aerial vehicle (UAV) with a solid-state laser, Technology Maturation Laser Weapon System Demonstrator (LWSD).[12]
