AUSTIN — AUSTin, Texas — The US Navy remains stuck in a legal battle with a Philippine-flagged cargo ship over how much it owes to American carriers.

The Coast Guard is also asking the US military to transfer its cargo to another US ship to make up the difference.

The Coast Guard says the Philippine ship, the Triton, is the only one of its kind in the world.

The Tritons owner says it is owed $20 million.

That is the sum the Coast Guard estimates the ship owes to carriers in the United States, Canada, Mexico and China.

But the Coast Guards claims it cannot pay because the ship is stuck in the Philippine court system, unable to leave the Philippines for the United State.

The dispute stems from a law that took effect in 2015 that gives the Philippines a sovereign immunity from US law.

The law allows the US government to hold a court hearing to determine if the ship was actually in the Philippines when it left.

The US Coast Guard has tried for years to get the ship to leave.

The US military’s Central Command said the ship had sailed through the disputed waters, but the court case has dragged on for years.

The Justice Department is seeking to overturn that ruling.
