Fatigue is setting in as a U.S. aircraft carrier nears its ninth month waging the most intense running sea battle since World War II

ABOARD THE USS DWIGHT D. EISENHOWER IN THE RED SEA — The combat markings emblazoned on the F/A-18 fighter jet tell the story: 15 missiles and six drones, painted in black just below the cockpit windshield.

As the jet sits on the deck of the USS Dwight D. Eisenhower aircraft carrier in the Red Sea, its markings illuminate the enemy targets that it's destroyed in recent months and underscore the intensity of the fight to protect commercial shipping from persistent missile and drone attacks by the Iranian-backed Houthi rebels in Yemen.

But they also hint at the fatigue setting in, as the carrier, its strike group and about 7,000 sailors close in on their ninth month waging the most intense running sea battle since World War II. That raises difficult questions about what comes next as U.S. military and defense leaders wrangle over how they will replicate the carrier's combat power if the ship returns home to Norfolk, Virginia.

Already, the carrier's deployment has been extended twice, and sailors post dark memes around the ship about only getting one short break during their steadily growing tour. Some worry they could be ordered to stay out even longer as the campaign drags on to protect global trade in the vital Red Sea corridor.

At the Pentagon, leaders are wrestling with what has become a thorny but familiar debate. Do they bow to Navy pressure to bring the Eisenhower and the other three warships in its strike group home or heed U.S. Central Command's plea to keep them there longer? And if they bring them home — what can replace them?

U.S. officials say that they're weighing all options
