While sliding beneath the Coronado Bridge aboard the bridge of both large vessel, I turned to the Captain and said, "Whoa ... What is that?" He replied, "That is a fairly new class of ships. Propelled by waterjets and resting on a lightweight, trimaran hull, it can turn while sitting, and flies through waters as shallow as about twelve feet." Later, I learned that this was the USS Montgomery, commissioned in September of 2016. As a Littoral Combat Ship, or LCS, its duties include operations such as shore patrol, combating piracy, and interactions with locals around the ports, in the "littoral zone," which means close to shore. What a stealthy, agile beast, she is.
