You may thinking of the Littoral Combat Ship (LCS). The Navy just announced in the past two weeks or so that its multi mission modular design was deficient and that they were scaling back on the total number of ships being constructed. The ships that are going to be built will be dedicated to single mission configurations. Part of the confusion may arise from the fact that there are two different LCS designs, one of which is a trimaran design.
The High Speed Vessel is a passenger and cargo catamaran ferry of Austrailian design built to commercial not military standards. It’s not a combatant; its role is intratheater logistics. They are lightly armed and would likely not have the detection and jamming system needed to defeat an anti ship missile. It is a successful design built in the US for both the Army and Navy.
By the way, this was a large missile. In the video, you can see the glow of the launch booster rocket as it detaches from the missile after launch.
Thanks for that.
