USS Jackson (LCS-6) littoral combat ship successfully completed the first of three scheduled full ship shock trials June 10, that reported by U.S. Navy.

The shock trials are designed to demonstrate the ship’s ability to withstand the effects of nearby underwater explosion and retain required capability. Jackson is currently ported at Naval Station Mayport, Florida, for required inspections and preparation for the second full ship shock trial scheduled for later this month.

The Freedom-class LCS USS Milwaukee will be subjected to shock trials later this summer. The Milwaukee, the third in her class, made news in December when she suffered damage to her combining gears and lost propulsion, 20 days after commissioning. She has since been repaired, and the Navy says that the issue does not affect her sister ships.

USS Jackson (LCS-6) is an Independence-class littoral combat ship of the United States Navy. She is the first ship to be named for Jackson, the capital of Mississippi.

Construction began on 1 August 2011 with the first cutting of aluminum at Austal USA’s Modular Manufacturing facility in Mobile, Alabama. The name of the ship was announced on 5 October 2011. The ship was launched on 14 December 2013. Jackson was delivered to the Navy on 11 August 2015 and placed into service that day.
