Why uncrewed vessels intended for LCS lost support

Why have so few Fleet-class uncrewed surface vessels been built for Freedom- and Independence-class littoral combat ships?

The answer links their limited production to loss of support for LCS and its associated systems after design problems, curtailed orders, and early retirements.

The question concerns Fleet-class uncrewed surface vessels intended to work with Freedom- and Independence-class littoral combat ships. Support for associated systems weakened with the parent LCS programme. The requirement for a 45-knot sprint is criticised as a major design compromise, since embarked helicopters and boats could undertake the cited customs intercepts. Curtailed production and early retirements left little incentive to fund the additional systems that were supposed to accompany the ships.
