US senator demands answers over USS Abraham Lincoln deployment

US Senator Richard Blumenthal has called on the Pentagon to explain why the USS Abraham Lincoln

WASHINGTON: US Senator Richard Blumenthal has called on the Pentagon to explain why the USS Abraham Lincoln has remained at sea for more than 250 days, raising concerns about the health, safety and readiness of thousands of sailors and Marines aboard the aircraft carrier.

Blumenthal, a member of the Senate Armed Services Committee, sent a letter to Defence Secretary Pete Hegseth and Acting Navy Secretary Hung Cao seeking detailed information about the carrier’s prolonged deployment.

The senator said the USS Abraham Lincoln left Naval Base San Diego on November 21, 2025, for what was originally expected to be a seven-month mission. Its deployment was scheduled to end in May but has since been extended, with no publicly announced date for its return.

According to Blumenthal, the carrier has spent more than 200 consecutive days without a port visit, setting a record for the length of time it has remained at sea without such a stop.

The prolonged deployment has triggered concerns about conditions aboard the carrier, including reported shortages of basic supplies, water contamination, plumbing problems and difficulties with mail deliveries.

Blumenthal also raised concerns about the mental health and morale of crew members, as well as deck safety and general living conditions.

He said reports of fatigue, deferred maintenance and limited opportunities for rest could increase the risks faced by personnel working aboard an aircraft carrier.

The USS Abraham Lincoln carries around 5,000 sailors and Marines and operates in an environment involving aircraft, fuel, weapons, heavy machinery and complex electrical systems. Blumenthal warned that prolonged exposure to these conditions could create additional safety risks if crews are exhausted or equipment maintenance is delayed.

The senator asked the Pentagon to provide information about reported habitability problems aboard the carrier, including issues involving hygiene supplies, mould, toilets, laundry facilities and water systems.

He also requested details about the Navy’s measures for monitoring crew fatigue, morale, mental health and operational readiness.

Blumenthal wants officials to disclose whether the extended deployment has been linked to increases in safety incidents, medical problems or disciplinary cases.

Reports cited by US military publications have also described incidents in which sailors aboard the carrier allegedly attempted to go overboard during its prolonged deployment, intensifying concerns about the psychological pressure on personnel.

The senator has asked the Navy to explain what measures are being taken to address such concerns and protect the wellbeing of the crew.

The extended deployment comes as the United States continues military operations and maintains a significant naval presence connected to tensions involving Iran and the wider Middle East.

Blumenthal questioned the Pentagon about the strategic purpose of keeping the carrier deployed for such an extended period.

He asked officials to explain the military objectives linked to the Lincoln’s continued presence in the region and how the Navy determines whether the carrier remains operationally necessary.

The senator also sought details about every extension of the carrier’s deployment, including who approved the extensions and what operational requirements were cited.

He further questioned whether the Navy’s existing fleet structure and deployment system can maintain the current demand for aircraft carriers without undermining crew welfare, equipment readiness and future maintenance requirements.

Blumenthal warned that maintaining a high operational tempo for an extended period could create a readiness problem in the future if the impact on personnel and equipment is not properly addressed.
