Stephen M. Carmel, writing in MarineLink, asserted that rebuilding the U.S. maritime industry must prioritize a commercial shipbuilding and operating base over an exclusive focus on building more Navy ships.[^1]

That erosion, Carmel argued, created a strategic vulnerability: the government became the sole customer for critical vendors, reducing economic health and resilience.[^2] The Jones Act requires that all goods transported by water between U.S. ports be carried on U.S.-built, U.S.-flagged, U.S.-owned and U.S.-crewed ships.[^3] The Merchant Marine Act of 1936 established the United States Maritime Commission and required a U.S. merchant marine with U.S.-built ships and citizen crews.[^4]

On the fleet's numbers, Jones Act construction costs run about three times foreign levels, and operating costs at least twice as much.[^5] Jones Act ships average 11 to 12 years old, about three times older than foreign ships.[^6] Oceangoing Jones Act ships fell 17% from 2006 to 2011, indicating too few ships relative to demand.[^7] A study was prepared for La Alianza Maritima de Puerto Rico, an industry trade association representing Jones Act ship operators and maritime unions in the Puerto Rico trade.[^8]
