A series of policy analyses argues the Jones Act makes US-flag shipping uncompetitive and reduces its military utility, citing higher operating costs and limits on shipyard modernization.

U.S. flag ships are more expensive to operate than international competitors because they require full U.S. crews and citizenship rules, according to one analysis[^4]. Another argues that because of the Jones Act, US carriers cannot contract with overseas shipyards and thus keep their existing ships[^3]. In 2019, MARAD Administrator Mark Buzby testified that US shipyards lack scale, technology, and series-building order books to compete with other countries[^5].

The military utility of the Jones Act fleet has faded because modern warfare requires transport ships that are fast and flexible, a separate study argues[^6]. In Hawaii and Puerto Rico, calls for change are ignored in Washington because special interests spend money to delay votes that benefit the nation, according to one analysis[^2].
