The US Navy’s tenth San Antonio-class amphibious transport dock John P. Murtha (LPD 26) has successfully completed the acceptance trials, validating the functionality of the ship’s system.
Trials were carried out by the navy’s Board of Inspection and Survey (INSURV) over a six-day period.
LPD 17 Class programme manager and ships programme executive office captain Darren Plath said: "The INSURV team provided a detailed assessment of the ship’s readiness through a rigorous schedule of test events.
"This included several systems new to the LPD 17 Class to include the SPS-48G air search radar and the navy multiband terminal satellite communications system.
"Overall, LPD 26 performed very well and will soon be another highly capable, combat ready ship delivered to the US Fleet."
The dockside checks validated the functionality of the ship’s key systems prior to the underway period.
During the at sea testing, the future USS John P. Murtha completed a series of demonstrations including a full power run, self-defence detect-to-engage exercises, steering checks, boat handling, anchoring and rapid ballast and de-ballast demonstrations.
The tests conducted during the underway period certified that all systems including main propulsion, ship control, combat, communications and damage control were fully inspected and validated for operational tasking.
Last month, the vessel completed the four-day builder’s trials that included a series of testing and at-sea demonstrations.
The 684ft-long San Antonio-class ships have a displacement capacity of 25,000t and more than 23,000ft² of vehicle storage, capable of transporting a landing force of up to 800 marines and their equipment.
The 11 San Antonio-class ships will functionally replace more than 41 ships across four classes, providing the navy and marine corps with modern, sea-based platforms.
