The US Naval Forces Central Command (NAVCENT) and forces attached to the United Arab Emirates (UAE), Bahrain and Israel are conducting a multilateral naval exercise.
The exercise between the four countries has been made public for the first time, according to reports.
It comes just one year after the UAE and Bahrain signed a US-brokered deal, called the Abraham Accords agreement, with Israel.
The five-day maritime security operations exercise, which began on 10 November, is being conducted in the Red Sea.
It includes at-sea training onboard the San Antonio-class amphibious transport dock vessel USS Portland (LPD 27). The training will cover tactics and techniques related to search and seizure.
NAVCENT noted that the naval drill will improve interoperability between maritime interdiction forces of the participating nations.
The US 5th Fleet is conducting the exercise.
NAVCENT commander US 5th Fleet and Combined Maritime Forces vice admiral Brad Cooper said: “It is exciting to see US forces training with regional partners to enhance our collective maritime security capabilities.
“Maritime collaboration helps safeguard freedom of navigation and the free flow of trade, which are essential to regional security and stability.”
The US 5th Fleet is based in the Gulf island state of Bahrain and operates in the Arabian Gulf, Gulf of Oman, Red Sea and parts of the Indian Ocean.
Its area of operations stretches across nearly 2.5 million square miles of water.
The US Navy recently deployed Arleigh Burke-class guided-missile destroyer USS Porter, the US naval tanker John Lenthall, and the US command and control ship (C2) Mount Whitney in the Black Sea.
