Pentagon: Chinese vessels harassed unarmed ship
BY PAULINE JELINEK, Associated Press Writer Pauline Jelinek, Associated Press Writer – 23 mins ago
WASHINGTON – The Pentagon charged Monday that five Chinese ships shadowed and maneuvered dangerously close to a U.S. Navy vessel in an apparent attempt to harass the American crew.

Defense officials in the Obama administration said the incident Sunday followed several days of "increasingly aggressive" acts by Chinese ships in the region. The incident took place in international waters in the South China Sea, about 75 miles south of Hainan Island.

U.S. officials said a protest was lodged with the Chinese government over the weekend and it was to be repeated to a Beijing military attache at a Pentagon meeting Monday.

The USNS Impeccable sprayed one ship with water from fire hoses to force it away. Despite the force of the water, Chinese crew members stripped to their underwear and continued closing within 25 feet, the Defense Department said.

"On March 8, 2009, five Chinese vessels shadowed and aggressively maneuvered in dangerously close proximity to USNS Impeccable, in an apparent coordinated effort to harass the U.S. ocean surveillance ship while it was conducting routine operations in international waters," the Pentagon statement said.

The Chinese ships included a Chinese Navy intelligence collection ship, a Bureau of Maritime Fisheries Patrol Vessel, a State Oceanographic Administration patrol vessel, and two small Chinese-flagged trawlers, officials said.

"The Chinese vessels surrounded USNS Impeccable, two of them closing to within 50 feet, waving Chinese flags and telling Impeccable to leave the area," officials said in the statement.

"Because the vessels' intentions were not known, Impeccable sprayed its fire hoses at one of the vessels in order to protect itself," the Defense statement said. "The Chinese crew members disrobed to their underwear and continued closing to within 25 feet."

Impeccable crew radioed to tell the Chinese ships that it was leaving the area and requested a safe path to navigate, the Pentagon said.

But shortly afterward, two of the Chinese ships stopped directly ahead of the Impeccable, forcing it to an emergency stop to avoid collision because the Chinese had dropped pieces of wood in the water directly in front of Impeccable's path.

"The unprofessional maneuvers by Chinese vessels violated the requirement under international law to operate with due regard for the rights and safety of other lawful users of the ocean," said Marine Maj. Stewart Upton, a Pentagon spokesman.

"We expect Chinese ships to act responsibly and refrain from provocative activities that could lead to miscalculation or a collision at sea, endangering vessels and the lives of U.S. and Chinese mariners," Upton added.

In Beijing, Chinese officials did not immediately respond to voicemail messages and e-mail.

China views almost the entirety of the South China Sea as its territory. China's claims to small islets in the region have put it at odds with five governments — the Philippines, Vietnam, Malaysia, Brunei and Taiwan.

Upton said U.S. Navy ships and aircraft routinely operate in the area and that Chinese ships and aircraft routinely steam or fly nearby. "However, these actions were considerably more aggressive and unprofessional than we have seen."

He said the Impeccable is one of five surveillance ships that gather underwater acoustical data.

The incident came just a week after China and the U.S. resumed military-to-military consultations following a five-month suspension over U.S. arms sales to Taiwan. And it came as Chinese Foreign Minister Yang Jiechi was due in Washington this week to meet with U.S. officials.

Pentagon officials said the close encounter followed several other incidents involving the Impeccable and another U.S. vessel Wednesday, Thursday and Saturday.

• On Wednesday, a Chinese Bureau of Fisheries Patrol vessel used a high-intensity spotlight to illuminate the ocean surveillance ship USNS Victorious as it operated in the Yellow Sea, about 125 nautical miles from China's coast, the Pentagon said. The move was made without notice or warning, U.S. officials said. The next day, a Chinese Y-12 maritime surveillance aircraft conducted 12 fly-bys of Victorious at an altitude of about 400 feet and a range of 500 yards.

• On Thursday, a Chinese frigate approached USNS Impeccable without warning and crossed its bow at a close range of approximately 100 yards, the Pentagon said. This was followed less than two hours later by a Chinese Y-12 aircraft conducting 11 fly-bys of Impeccable at an altitude of 600 feet and a range from 100-300 feet. The frigate then closely crossed Impeccable's bow yet again, this time at a range of approximately 400-500 yards without rendering courtesy or notice of her intentions.

• On Saturday, a Chinese intelligence collection ship challenged USNS Impeccable over bridge-to-bridge radio, calling her operations illegal and directing Impeccable to leave the area or "suffer the consequences."

Sunday's incident is reminiscent of a similar early foreign policy crisis that forced former President George W. Bush to deal with Beijing shortly after he took office — China's forced landing of a spy plane and seizure of the crew in April 2001.

That incident between a Chinese jet and U.S. Navy spy plane infuriated Defense Secretary Donald Rumsfeld, who responded by breaking off U.S. military contacts with China for a time.

The Chinese fighter jet collided in midair with a U.S. Navy EP-3 surveillance plane. The Navy plane was so badly damaged...

Perhaps the Chinese are getting fed up with the big honking set of ears in the water so close to home.

for anyone wondering......

http://www.globalsecurity.org/military/systems/ship/tagos-23.htm

The mission of the T-AGOS 23 Class ships is to collect, process, and transmit acoustic data in support of the Integrated Undersea Surveillance System (IUSS) mission requirements. The ship will be operated by the Military Sealift Command (MSC) utilizing both civilian and naval personnel to carry out its mission. In short, this vessel is used by the military to track submarines, and is the quietest vessel the government operates, outside of submarines themselves. The unique hull form is one of the most impressive features of this massive 281-foot vessel.

Surveillance ships serve as a stable platform to gather underwater acoustical data. IMPECCABLE was specifically designed to deploy two underwater listening devices called surveillance towed-array sensor system (SURTASS) used to augment the Navy's antisubmarine warfare capability. The SURTASS mission is to gather ocean acoustical data and, through electronic equipment onboard, process and provide rapid transmission of antisubmarine warfare information via satellite to shore stations for evaluation and analysis.

The keel for the first Impeccable class was laid down Feb. 2, 1993. Ship was more than 60 percent completed when the shipyard encountered difficulties. The contract was sublet to Halter Marine in Pascagoula, MS on April 20, 1995 to complete the ship, with a planned christening date of early 1999.

On 01 November 2000 Friede Goldman Halter, Inc. announced the christening of the USNS Impeccable (T-AGOS 23) at their Pascagoula, MS yard. The remaining four ships of the program (AGOS 24-27) will not be constructed. The Government made the USNS IMPECCABLE (T-AGOS-23) available for repairs from 27 August 2001 through 26 September 2001. The Government projected that it would take 12 consecutive days to complete the Drydocking repairs. The ship is homeported at Saint Helena's Annex, Virginia.

The Small Waterplane Twin-Hull-Active (SWATH-A) T-AGOS is the third generation of T-AGOS. Originally designed as a multi-purpose hull configuration, only the SURTASS application has been implemented. This ship is 281 feet in length, has a beam of 95.9 feet, displaces 5,370 long tons, and is capable of sustaining speeds up to 12 knots.

Built on a small water plane area twin hull design for greater stability at slow speeds in high latitudes under adverse weather conditions, Impeccable class ships have a hull form based on that of Victorious. IMPECCABLE is larger and faster then her predecessors, VICTORIOUS Class ships. This vessel is a larger version of the SWATH-P (T-19 Class) ships with 47 extra feet in length and almost 2000 tons greater displacement. The ship is powered by a larger diesel electric propulsion system that generates 5000 shaft horsepower. The larger hull design provides the same stable, hospitable environment as the smaller SWATH-P platforms with the additional space, displacement and power needed to accommodate not only the passive acoustic system, but also Low Frequency Active sonar. The ship is crewed by approximately 20 civilian mariners, 10 technicians, and up to 20 Navy personnel. T-23's larger dimensions are necessary to provide accommodations for the 43 man crew, made up of a mix of military operators, MSC crewmen and O&M technicians.

The T-23 Class will be equipped with a vertical line active transmit array, a multi-frequency horizontal receiver array and a real-time processing and analysis suite to accomplish both the active and passive surveillance missions for which it was designed. In addition to primary acoustic mission equipment, T-23 is also outfitted with an extensive suite of navigation, communications, command and control and support equipment.

Acoustic systems include an active low frequency towed array, which has a series of modules each of which houses two high-powered active transducers. These can be used with either mono or bistatic receivers. Oceanographic and hydrographic surveys, underwater surveillance, acoustic research and submarine support are just a few of the services these ships support. The ships are operated and maintained by civilian contractors. The Surveillance Towed Array Sensor is a linear array deployed on a tow cable. Information from the array is relayed via WSC-6 (SHF) SATCOM link to the shore. These ships have the same WSC-6 communications, links and operating procedures as the Stalwart class. SURTASS patrols are 60 to 90 days in duration.

The Surveillance Towed Array Sensor System [SURTASS] Low Frequency Active (LFA) is the active adjunct to the towed array. LFA adds an active transmit array and handling system, power amplification and control systems, an active signal processing and display receive system, and an environmental analysis system to the SURTASS Upgrade. A prototype LFA system has been installed on a leased commercial vessel, Cory Chouest, and operated as an interim LFA asset pending delivery of T-AGOS-23 (SWATH-A), which will be equipped with LFA.

T-AGOS ships are operated by the Military Sealift Command and are under the administrative command of Commander, Undersea Surveillance. They are deployed under the Operational Control (OPCON) of the Theater ASW Commanders, CTF 84 and CTF 12. Civilian technicians who operate and maintain the mission equipment man the SURTASS Operations Center (SOC), the nerve center of the ship. When operating with tactical forces, military detachments are embarked for onboard analysis and direct reporting to fleet units. A SURTASS mission consists of 60 days on station while towing an array of hydrophones that collect acoustic data.

On 16 August 2000 the Military Sealift Command awarded a three-year contract for more than $108 million to Maersk Line, Limited of Norfolk, VA, to operate and maintain all 14 MSC-owned Auxiliary General Ocean Surveillance T-AGOS class ships. The fourteen ships support four Department of Defense programs: the Navy's Surveillance Towed Array Sensor System (SURTASS) operations; Navy, Atlantic Fleet and U.S. Coast Guard counter drug initiatives; and the Air Force Electronic Systems Command's radar missile tracking system.
 
Based on the southern most point of Hainan, the incident occurred somewhere within the rose arc. Pretty close to the PLA base on the Paracels as well. Not far from Vietnam.

The US keeps tabs on everyone.  >:D

Pretty map. The USNS vessel was in fact keeping tabs on PRC sub activity,which the reds dont seem to like. :)
 
The USNS Impeccable now has an escort: the AEGIS Destroyer USS Chung Hoon.

US Ship in China Scrape Assigned Escort
March 12, 2009
Associated Press

WASHINGTON - The Navy has assigned a heavily armed destroyer to escort the U.S. surveillance ship that got into a high-seas confrontation with Chinese ships last weekend.

A defense official says the Hawaii-based destroyer USS Chung-Hoon is keeping a close eye on the unarmed sub-hunting ship Impeccable as it continues operations in the South China Sea. The official spoke on condition of anonymity to describe sensitive ship movements.

The official says the escort ship joined the Impeccable on Wednesday.

China has demanded that the United States quit surveillance work in a disputed area far off the Chinese coastline. U.S. officials say they won't back off.

The Chung-Hoon is among the Navy's newest and most sophisticated warships. It joined the fleet in 2004.

[size=14pt]Inside the Ring: New naval harassment in Asia

USNS Impeccable


A U.S. intelligence-gathering ship was harassed by a Chinese security ship last month in an incident that analysts say indicates Beijing is stepping up aggressive maritime encounters toward the U.S. Navy in the Asia-Pacific.

A Chinese website, Sinocism, posted photographs of what it described as a “fierce confrontation” between the USNS Impeccable, an electronic spy ship, and a China Maritime Surveillance ship.

The Web posting said the Chinese ship videotaped the encounter and posted it online as a way to “expose the activity.” Photos of the Impeccable indicate they were taken on June 21.

The Chinese ship also warned the Navy vessel it was operating “illegally” despite being in undisclosed international waters. The Chinese also said the ship was not a “noncombatant” ship.

“The American vessel USNS Impeccable is far from being a noncombatant,” the Chinese posting stated. “The Impeccable is one of five American surveillance ships equipped with passive and active low-frequency towed-array sonar, and it is effective at detecting submarines, directly serving the American naval fleet by doing so.”

The Navy is stepping up surveillance of China’s submarine force, which has expanded by more than 50 submarines in the past two decades.

The Sinocism posting stated that the U.S. ship was within 100 nautical miles of the Chinese coast and that China had not granted permission for it to operate in that region.

The Chinese photos appear to have been taken by a cellphone camera from a distance of about 10,000 yards. Analysts suggested the Chinese were engaged in long-distance countersurveillance, thus raising questions about Chinese claims of a “fierce” encounter.

A video of the confrontation posted on another website shows a Chinese security officer on ship speaking into a microphone and demanding that the U.S. ship must first get China’s permission to be in the area.

An unidentified U.S. official was then heard in the radio message as saying the Impeccable was operating legally in international waters. (The video can be viewed at cjdby.net/redianzhuizong/2013-07-04/military-4476.html.)

The last time the Impeccable was harassed by the Chinese was in March 2009 when five Chinese ships shadowed the surveillance vessel and sprayed it with water in what the Pentagon at the time said was a “dangerous” effort to force the ship out of its operating zone. Another spy ship, the Victorious, also was harassed several years ago.

A U.S. Pacific Command spokesman would not address the U.S.-China ship incident. Capt. Chris Sims, the spokesman, referred Inside the Ring to comments made last week by Adm. Samuel J. Locklear, head of U.S. Pacific Command.

Asked about an increase in Chinese naval activity around Guam and Hawaii, in apparent retaliation for U.S. naval spying on China, Adm. Locklear said the United States and China disagree on U.N. definitions of controlled waters.

“We believe, the U.S. position is that those activities are less constrained than what the Chinese believe,” the four-star admiral said in a meeting with reporters July 11.

Adm. Locklear said economic exclusion zones cover “most of the major sea lines of communication” that are vital for trade and shipping.

Sounds like someone has been watching too much "Whale Wars". ;D
 
It's all fun and games picking on the little guy... Until the big brother shows up. Big brother being a Arleigh Burke-class destroyer  ;D
 
Its all about sending a message.The PRC doesnt like the USN operating near China and the USN is asserting the right of free passage in international waters.
