The US Navy faces mounting pressure from record deployments, shipbuilding bottlenecks and President Donald Trump’s plans for a larger fleet and new carrier technology.

The US Navy is facing a growing readiness challenge as President Donald Trump pushes an ambitious expansion of the fleet while existing ships and crews remain under heavy operational pressure.

The strain has come into sharp focus with the USS Abraham Lincoln, which has spent more than 260 days at sea during the US-Iran conflict. Reports of supply problems, difficult living conditions and concerns over sailors’ mental health have triggered questions about how long the Navy can sustain such deployments.

At the same time, Trump’s administration is pursuing a costly naval expansion, including a proposed fleet of nuclear-powered battleships, a new shipyard and major changes to aircraft-carrier technology. The combination is placing fresh demands on an industrial base that already struggles to deliver ships on schedule.

Lincoln Deployment Raises Concerns

The Abraham Lincoln’s unusually long deployment has become a symbol of the pressure on US naval personnel.

The carrier has operated for more than nine months with limited opportunities for port visits. Families of sailors have raised concerns about mental health, supplies and living conditions, while Navy officials have acknowledged that the deployment has placed significant pressure on the crew.

The Pentagon is preparing to replace the Lincoln with the USS George Washington, which has begun moving towards the Middle East from the Pacific. The move could temporarily leave the western Pacific without a US aircraft carrier.

Global Missions Stretch Fleet

The Lincoln’s deployment reflects a broader problem for the US Navy: it must maintain a global presence while giving ships and sailors enough time for maintenance and recovery.

The continuing demands of operations in the Middle East have forced the Navy to shift assets between regions. Moving the George Washington towards West Asia illustrates how one deployment can affect the wider distribution of American naval power.

The situation has also renewed debate over deployment lengths and the impact of prolonged operations on crew readiness.

Golden Fleet Faces Shipyard Test

Trump has simultaneously pushed the proposed “Golden Fleet”, which includes a new class of large nuclear-powered battleships.

The Congressional Budget Office has warned that the Navy has repeatedly struggled to meet its long-term fleet expansion goals. In recent years, shipyards have had access to resources but have still struggled to deliver ordered vessels on time.

CBO analysis of the Golden Fleet has also pointed to potential pressure on the industrial base, particularly from large surface combatants.

The proposed battleship programme therefore faces a basic question: whether American shipyards can build new classes of warships without further delaying vessels already in the pipeline.

Shipbuilding Capacity Remains Weak

The administration has responded by seeking additional industrial capacity.

Trump’s latest naval memorandum calls for the establishment of a fifth public shipyard and allows limited overseas construction of Navy ships by foreign yards with significant US investment. The measures aim to increase production and reduce bottlenecks.

However, expanding shipbuilding capacity cannot happen overnight. Nuclear-powered warships require specialised facilities, trained workers, complex supply chains and lengthy certification processes.

That makes rapid fleet expansion difficult even with additional government funding.

Trump Orders Steam Catapults

Another major change involves the Ford-class aircraft carriers.

Trump has directed the Navy to develop a plan to replace the electromagnetic aircraft launch system, or EMALS, with traditional steam catapults on the future USS Doris Miller and subsequent carriers.

The decision reverses years of investment in electromagnetic technology. Reuters reported that EMALS production for the Doris Miller was already nearly 50 per cent complete when the administration ordered the change.

The first three Ford-class carriers will retain their electromagnetic systems, meaning the change primarily affects future ships.

Technology Shift Could Cost More

The reversal could create additional engineering and integration work.

General Atomics, the company involved in EMALS, has warned that abandoning the system after years of development could create cost and scheduling risks. Defence analysts have also questioned the practicality of introducing a different launch system into a carrier design built around electromagnetic technology.

For the Navy, the decision comes at a time when it is already trying to control delays across several major shipbuilding programmes.

Navy Faces Competing Demands

The US Navy now faces several pressures at once: crews require relief, existing ships need maintenance, shipyards need greater capacity and the administration wants a larger and more technologically capable fleet.

Trump’s plans could eventually expand American naval power, but the immediate challenge is implementation. The service must increase production without worsening existing delays and maintain global deployments without exhausting personnel.

For the US Navy, the Abraham Lincoln’s extended mission has shown the human cost of operating an overstretched fleet, while the Golden Fleet and carrier technology changes could add further demands on an already pressured system.
