On January 10, 2012, Austal’s Mobile, Alabama shipyard completed the launch of the second 127-metre Independence-Variant Littoral Combat Ship, “Coronado” (LCS 4).

The roll-out marked Austal’s second use of an innovative self-propelled modular transporter system to transfer the ship from the yard’s final assembly bay onto a drydock for launch. This system was first used a few months ago, in September 2011, to successfully launch USNS “Spearhead” (JHSV 1). Austal and the US Navy collaborated in the design of a new set of keel stands to support the ship during construction and facilitate the transition from the assembly bay. Austal’s own self-propelled modular transporters (SPMTs) supplemented those of Berard Transportation of New Iberia, LA, to provide a total of 3,800 tons lift capacity, on some 104 axle lines.
