LCSP
Life Cycle Sustainment Plan
What it actually means
The program document laying out how the system will be supported for its whole service life — maintenance concept, support strategy, product support arrangements, sustainment metrics, and the funding those require. It exists to force sustainment thinking during design, when supportability is still cheap to influence.
Where you'll meet it
Milestone documentation and sustainment reviews on DoD programs.
