As one cutter departs, another deploys to maintain Coast Guard presence in Western Pacific

YOKOSUKA NAVAL BASE, Japan — As the Coast Guard cutter Bertholf concluded six months deployed in the Western Pacific, its sister ship, the cutter Stratton, left its homeport in California on Wednesday to take its place, according to the Coast Guard.

While operating in the Pacific, under the aegis of the 7th Fleet, the Bertholf sailed with a Navy guided-missile destroyer through the Taiwan Strait, the first Coast Guard cutter to do so. It also sailed through contentious waters of the East China Sea and exercised with ships of the Philippine coast guard near Scarborough Shoal, a ring of sand in the South China Sea claimed zealously by China.

Sending the Bertholf and the Stratton, both national security cutters, represents a law enforcement approach to a problem of international relations. The Coast Guard has operated in the Western Pacific previously, but not in such high-profile fashion.

“This is, for us, just a return to engagement in an area that we have been and conducted operations in before and consistent with international law,” said Vice Adm. Linda Fagan, commander of the Coast Guard Pacific Area, in a conference call with reporters Tuesday.

In addition to exercising rights of free navigation in Western Pacific, the Bertholf also policed ship-to-ship transfers of goods barred by international sanctions from entering North Korea.

Coast Guard vessels, with their white hulls and orange bands, represent something less than a military threat to potential adversaries. U.S. vessels in the Western Pacific are often shadowed by Chinese ships.

Fagan said the service committed to provide the Defense Department “a ship into the Western Pacific to partner and engage and bring our unique Coast Guard authorities and access into the region” while discussing Pentagon resourcing a few years ago.

White hulls

Philippine Coast Guard Lt. Cmdr. Jay Terriela during an April presentation to the Yokosuka Council on Asia-Pacific Studies said Indo-Pacific nations are increasingly engaging in “white hull” diplomacy, using their coast guards — not always their navies — to challenge China’s maritime territorial claims.

“[The] China trend is a reason why the coast guard is getting bigger, but only in the last decade,” he said of the increasing coast guard presence in the Indo-Pacific.

Fagan in a January press release called the Bertholf’s deployment a “force multiplier” in its work with the Defense Department.

She said the Coast Guard is committed to a “free and open Indo-Pacific and a rules-based international system.” Defense officials commonly use this phrase when referring to growing challenges in the region as countries — most notably, China — make claims to land features in the South China Sea not recognized by international law.

With each land mass claimed comes the assertion that the 12 nautical miles around the islets are the country’s territorial waters. China claims 27 features in the South China Sea, according to the Center for Strategic and International Studies Asia Maritime Transparency Initiative. The Chinese navy regularly follows foreign vessels that come within the 12 nautical miles without first seeking permission.

The Coast Guard’s dual role as a federal law enforcement agency and an armed force allows the it “to conduct defense operations in support of combatant commanders on all seven continents,” according to the Tuesday statement.

When the Bertholf left Alameda Coast Guard Base in January, its commanding officer, Capt. John Driscoll, in a video the commandant posted to Twitter Jan. 20, said the ship would “live up to the name ‘national-security cutter.’”

National-security cutters are equipped with advanced command-and-control features and for long-range patrols. Each ship is 418-feet long, can carry a crew of 170 and travel at speeds beyond 28 knots. The Coast Guard in August will commission two new national-security cutters to be based in Hawaii.

“When we get underway, we’re going to be working for the United States Indo-Pacific Command combatant commander and we’re going to be executing national-security operations throughout the Pacific,” Driscoll, in the video, tells his crew.

A cutter first

Two months later, the Bertholf sailed through the Taiwan Strait with the USS Curtis Wilbur – the seventh such transit by U.S. naval vessels since July but the first by a U.S. Coast Guard cutter. The 110-mile-wide strait separates Taiwan from mainland China.

Afterward, Chinese Foreign Ministry spokesman Geng Shuang said Beijing protested to U.S. leaders.

The Bertholf also raised eyebrows in Beijing when it practiced search-and-seizure procedures last month with the Philippine coast guard near Scarborough Shoal. Both the Philippines and China claim the shoal, but China “effectively controls” it with a constant coast guard presence there since 2012, according to the Asia Maritime Transparency Initiative.

The cutter also made port visits in Hong Kong — the first for a Coast Guard cutter in 17 years — and in Manila — the first for the service in seven years.

Fagan said the Coast Guard is interested in helping partner nations improve their maritime law-enforcement capabilities. “We’ll do things like send a small training team into a nation and help teach them how to do a fisheries enforcement boarding to guard against fishing incursions,” she said. “When Stratton gets into theater, you’ll see some similar engagement, partnership capacity-building and a continued commitment to a safe, secure, predictable conduct of vessels navigating on the high seas.”
