Operation Tomodachi


Operation Tomodachi was a United States Armed Forces assistance operation to support Japan in disaster relief following the 2011 Tōhoku earthquake and tsunami. The operation took place from 12 March to 4 May 2011; involved 24,000 U.S. servicemembers, 189 aircraft, 24 naval ships; and cost $90 million.

Bases and commands

Many, if not most, of the U.S. military bases in Japan were involved in some manner in Operation Tomodachi.
Col. Stephen Bissonnette, deputy commander of the 353rd SOG stated that "he devastation caused by the earthquake is truly heartbreaking...As part of coordinated relief efforts, the group will work tirelessly with our Japanese counterparts and other relief organizations to help the people affected by the earthquake recover..." The US aid efforts are conducted under the direction of Japanese government or military authorities.

Navy

The United States Navy quickly responded to provide aid. Aircraft from three FLSW squadrons were in theatre during the earthquake at Naval Air Facility Atsugi. VR-62's C-130 delivered 127 tons of material to aid in relief efforts and VR-58's C-40 delivered 366,000 pounds of food and water and 1400 passengers. VR-52's aircrew and maintenance detachment moved Navy patrol and helicopter units directly involved with the search and rescue of survivors in addition to relocating 185 Navy personnel and dependents from the Atsugi-based Carrier Air Group Five to Guam. During this time, the Taskmasters were airborne for 19 out of 26 hours transporting personnel and humanitarian relief supplies. The aircraft carrier and its battle group were moved to the east coast of Honshu. As well as the group's own helicopters, the Ronald Reagan served as a refueling platform for Japan Self-Defense Forces helicopters. C-2 Greyhound aircraft assigned to VRC-30 and attached to CVW-14 and CVW-5 ferried over 100 tons of food, water, blankets, clothing, and medical supplies from NAF Atsugi to USS Ronald Reagan for distribution by helicopter to local sites in Japan.
Yokota Air Base was used in the aftermath of the earthquake as a landing field for commercial flights as Tokyo Narita Airport was closed. The Navy helicopters based at Naval Air Facility Atsugi and elsewhere were made available for search and rescue immediately after the tsunami, including searching off-shore debris fields and later assisted with food drops. P-3 Orion aircraft were used to do damage surveys. Amphibious landing craft and utility landing craft were used to deploy U.S. and Japanese troops and supplies to areas where docks were damaged. Japan electrical company trucks were moved by U.S. LCUs from, notably to Oshima Island.
The destroyers and were off the Bōsō Peninsula at the time of the earthquake, and their helicopters were made available for search and rescue. The landing ships and, with the embarked 31st Marine Expeditionary Unit from Okinawa, were moved from the Sea of Japan to the east coast of Japan.
, which had just arrived in Singapore at the time of the earthquake, was loaded with relief supplies and prepared to sail for Japan.
, an amphibious dock ship, embarked two MH-53E Heavy Lift Helicopters assigned to HM-14 DET 1 stationed in Pohang South Korea. The entire DET was on board Tortuga less than 18 hours after the earthquake and tsunami hit. Tortuga transported 300 Japan Ground Self Defense Force personnel and 90 vehicles from Hokkaido to Honshu.
Military Sealift Command ships also took part in the operation by transferring relief supplies and fuel to other supporting ships. The ships that took part in the operation were USNS Carl Brashear, USNS Pecos, USNS Rappahannock, USNS Matthew Perry, USNS Bridge.
, which was stationed at U.S. Fleet Activities Sasebo, arrived at Hachinohe, Japan with Explosive Ordnance Disposal Mobile Unit 5 and Underwater Construction Team 2 to clear wreckage from a local commercial channel.
During the operation the 7th Fleet flew 160 search and relief sorties for 1,100 flight hours, delivered 260 tons of relief supplies, and helped clear the ports of Hachinohe, Aomori, Miyako, Iwate, and Kesennuma, Miyagi.
In total 130 aircraft, 12,510 personnel and over 16 American naval ships took part in Operation Tomodachi, including USS Ronald Reagan, USS Chancellorsville, USS Cowpens, USS Shiloh, USS John S. McCain, USS Fitzgerald, USS Stethem, USS McCampbell, USS Preble, USS Mustin, USS Germantown, USS Tortuga, USS Harpers Ferry, USS Essex, USS Blue Ridge, USNS Safeguard.

Radiologic incidents

The US Navy dispatched aircraft carrier and other vessels which flew a series of helicopter operations. A spokesman for U.S. 7th Fleet naval personnel stated that monitoring equipment indicated that the warship had been exposed to radiation. Separate hand-held equipment also picked up the contamination on 17 crew members, who had participated in rescue operations. Commander Jeff Davis said that the exposure was low enough that after the crew washed with soap and water, follow-up tests were negative. Davis characterized the exposure as comparable to routine civilian activities and reiterated the US Navy's commitment to the relief operation. As a precaution, the aircraft carrier was repositioned farther offshore, away from the downwind direction of the plant and decontaminated. Several helicopters were decontaminated after returning from flights. One helicopter made a landing at Fukushima Airport after experiencing rotor icing and exposed some Australian and New Zealand search and rescue team members to low levels of radiation.
Radiation precautions were taken at U.S. bases, including USS George Washington leaving port at Yokosuka after very low levels of radiation were detected there. Part of its air complement moved to Misawa Air Base to support relief operations. External scientists not participating in the Operation have concluded these precautions failed to protect not only American military members, but also the millions of citizens in Japan operating under the auspice that radiation wasn't a concern. The effects of the radiation have not been analyzed in detail to conclude one way or the other. Further, it is alleged that there were pressures by the countries of Japan and the United States, in order to not disturb their international relationship, to pressure media sources to not accurately report on the severity of the radiation exposure.
Three years after the accident, servicemen who were part of the operation have reported radiation-related disorders, including cancers, thyroid disease, uterine bleeding and other ailments. 51 crew members have filed a lawsuit against the Tokyo Electric Power Company, which owns the Fukushima Daiichi power plant.

Marine Corps

facilities in Japan escaped major damage, with no reported casualties. This intact infrastructure allowed Marines from III Marine Expeditionary Force and Marine Corps Base Camp Smedley D. Butler to mobilize aid quickly.
Marines based at Marine Corps Air Station Futenma moved command and control teams and systems to NAF Atsugi. Eight KC-130Js from VMGR-152 and eight CH-46E and four CH-53 Super Stallions transport helicopters from HMM-265, all from MCAS Futenma, were made available to transport rescue teams and equipment, as well as provide search and rescue.
The 31st Marine Expeditionary Unit responded to Northern Japan from Malaysia and Indonesia, where the unit was conducting Theater Security Cooperation exercises. The 31st MEU delivered relief supplies to five cities, one island and one Japanese ship. More than 164,000 pounds of food and relief supplies were delivered, along with thousands of gallons of water. Elements of the 31st MEU, including Combat Logistics Battalion 31, 2nd Battalion 5th Marines went ashore on Oshima Island to deliver critical supplies and assist in debris removal.
MV Westpac Express, a civil-registered fast ferry chartered by the Marine Corps, was made available to transport equipment from Okinawa to Honshu. Westpac Express made two sorties in support of Operation Tomodachi. The ship moved 450 tons of cargo, including 7-ton trucks, fuel tankers, generators and water tanks from Okinawa to Iwakuni, Japan, arriving 15 March. On 20 March, Westpac Express loaded 226 pallets of bottled water at Pohang, ROK, off-loading at Iwakuni the next day.

Air Force

A United States Air Force KC-135 Stratotanker arrived at Misawa Air Base on 14 March with the first batch of relief workers and 50 civil engineers from Kadena Air Base.

Two C-17A Globemaster cargo aircraft from Joint Base Lewis-McChord were made available to transport rescue teams and equipment. A Global Hawk unmanned aerial vehicle was deployed from Guam for damage assessments.
