The Coast Guard also placed an order for three sets of long lead time material (LLTM) to support future production. The total value of the production and long lead time material orders is approximately $110 million. Public Law 119-21, the One Big Beautiful Bill Act, provided $51 million, covering production of the second WLIC and two sets of long lead time material. They are the only Coast Guard platform with the capability to drive and remove piles, erect towers and effect major structural changes. The Coast Guard inland fleet is responsible for maintaining more than 28,200 marine aids throughout 12,000 miles of inland waterways, through which an estimated 630 million tons of cargo move annually.
