U.S. 6th Fleet joins multinational maritime exercises led by France

Warships from the U.S. Sixth Fleet have joined France and four other NATO allies in an annual French-led maritime exercise in the Mediterranean, the navy said on Wednesday.

“US forces joined forces with Italian, Greek, Spanish and British navies to develop interoperability and combat skills at the high-end air strike group level among NATO allies during the maritime exercise from France, ”the navy said in the press release.

Arleigh Burke Porter-class guided missile destroyer (DDG 78), a Navy P-8A Poseidon aircraft and Fleet Replenisher John Lenthall joined the exercise on Monday, four days after the start of the exercise on 18 November, according to the statement.

French units scheduled to participate in Exercise Polaris 21 include the French aircraft carrier Charles de Gaulle, other French ships and units of the French Air Force and Air Force, added the press release.

NATO’s involvement includes Italian Navy destroyer Carlo Bergamini, Spanish Navy destroyer Mendez Nunez, Hellenic Navy frigate Adrias and British Royal Navy destroyer HMS Dragon (D35), the statement said.

Exercise Polaris 21 – Navy

Increasingly, NATO allies are expanding their high-end maritime combat capabilities by integrating into multinational exercises and carrier carrier group deployments, the statement said.

Other recent examples of integration for the US Navy include Porter’s participation in the British Royal Navy Fleet Sea Training Exercise and the integration of the Sullivans into the deployment of the British aircraft carrier Queen Elizabeth. , according to the press release.

US seeks to fill Arctic Gap in GPS with new system using cosmic rays – Navy

Scientists from four countries are trying to develop a new navigation system, as precise as the global positioning system (GPS), which uses radiation from space instead of satellites, the Office of Naval Research said on Wednesday.

“A team of researchers from Japan, UK, US and Finland… will use a natural source of radiation called cosmic-ray muons as an alternative to GPS signals derived from satellites,” the Office of Naval said. Research in a press release.

The team won a recent competition calling for international projects to fill gaps in GPS coverage in polar regions. The competition was jointly sponsored by the Office of Naval Research and the US Army Development Command, the statement said.

“The ability to navigate the polar regions will be of increasing importance over the coming decades as climate change opens up arctic waterways to commercial and military activities,” team leader Chris Steer said in the statement. .

After initially testing the system in a large water immersion tank in the UK, the project will move to Finland to deploy in an arctic lake covered by a meter of ice, the statement said.

Muons are subatomic particles capable of traversing rock, buildings, land and underwater – areas where GPS communications cannot be received, the statement added.

While the statement focused on potential scientific applications in underwater environments, tunnels and other underground environments, it made no mention of the obvious military implications of a navigation system in a future conflict, in which adversaries could. attempt to deactivate existing GPS satellites.
