The US Navy has started Citadel Pacific 2019, an annual anti-terrorism force protection exercise intended to increase the readiness of forces.

Running until 28 June, the exercise will involve the participation of US Navy installations in the Pacific, including Joint Region Marianas, Navy Region Japan and Navy Region Hawaii, along with their installations.

Exercise Citadel Pacific is aimed at improving the training, readiness, and capability of navy security personnel so that they can counter threats to installations, commands and units.

Conducted by US Pacific Fleet Commander and Navy Installations Command commander, the exercise will provide realistic scenarios to the participating personnel.

These scenarios will allow the security forces to hone their skills and improve their preparedness to respond to changing and dynamic threats.

The Navy Installations Command consists of around 52,000 military and civilian personnel deployed in 11 regions at 71 installations around the world.

The command provides support services for the military branch’s fleet, fighters and their families.

Officials stated that the exercise is a regularly scheduled exercise and not being held in response to any specific threat.

In a statement, the navy said: “Measures have been taken to minimise disruptions within local communities and to normal base operations, but there may be times when the exercise causes increased traffic around bases or delays in base access.”

Last month, the navy held a multinational exercise in the Western Pacific. The Pacific Vanguard exercise near Guam also involved warships from allies Japan, Australia and South Korea, including three destroyers and two frigates.

More than 3,000 forces took part in the six-day exercise.
