The Littoral Combat Ship (LCS), sometimes referred to as the "Little Crappy Ship," has suffered from uncontrolled cost overruns, delivery delays, and various mechanical problems.
The Navy has pumped around $30 billion over roughly 20 years into this project, which was started to create an inexpensive vessel that was small, fast, and capable of handling a variety of missions in coastal waterways.
The LCS was specifically designed to carry out anti-submarine warfare, mine countermeasure, and surface warfare missions in contested littoral waters, but there have been a lot of problems with the modular mission packages designed to be loaded aboard.
There are also concerns that the ships are not survivable in high-intensity conflict and that they are not sufficiently armed to perform their missions, according to the most recent Department of Defense operational testing and evaluation assessment.
While the Navy initially aimed to build a fleet of 55 ships, the LCS order has since been reduced to 35. The Navy, which has struggled to deploy the ships it already has, is currently looking at new missile frigates to replace the LCS.
