V-22s outfitted with specialized communications gear. In 2013, following Typhoon Haiyan, 12 MV-22s of the 3rd Marine Expeditionary Brigade were deployed to the Philippines for disaster relief operations; its abilities were described as "uniquely relevant", flying faster and with greater payloads while moving supplies throughout the island archipelago. U.S. Air Force The USAF's first operational CV-22 was delivered to the 58th Special Operations Wing (58th SOW) at Kirtland Air Force Base, New Mexico, in March 2006. Early aircraft were delivered to the 58th SOW and used for training personnel for special operations use. On 16 November 2006, the USAF officially accepted the CV-22 in a ceremony conducted at Hurlburt Field, Florida. The USAF's first operational deployment sent four CV-22s to Mali in November 2008 in support of Exercise Flintlock. The CV-22s flew nonstop from Hurlburt Field, Florida, with in-flight refueling. AFSOC declared that the 8th Special Operations Squadron reached Initial Operational Capability in March 2009, with six CV-22s in service. In December 2013, three CV-22s came under small arms fire while trying to evacuate American civilians in Bor, South Sudan, during the 2013 South Sudanese political crisis; the aircraft flew to Entebbe, Uganda, after the mission was aborted. South Sudanese officials stated that the attackers were rebels. The CV-22s had flown to Bor over three countries across . The formation was hit 119 times, wounding four crew and causing flight control failures and hydraulic and fuel leaks on all three aircraft. Fuel leaks resulted in multiple air-to-air refuelings en route. After the incident, AFSOC developed optional armor floor panels. The USAF found that "CV-22 wake modeling is inadequate for a trailing aircraft to make accurate estimations of safe separation from the preceding aircraft." In 2015, the USAF sought to configure the CV-22 to perform combat search and rescue in addition to its long-range special operations transport mission. It would complement the HH-60G Pave Hawk and planned HH-60W rescue helicopters, being employed in scenarios where high speed is better suited to search and rescue than more nimble but slower helicopters. U.S. Navy The V-22 program originally included Navy 48 HV-22s, but none were ordered. In 2009, it was proposed that it replace the C-2 Greyhound for carrier onboard delivery (COD) duties. One advantage of the V-22 is the ability to deliver supplies and people between non-carrier ships beyond helicopter range. Proponents said that it is capable of similar speed, payload capacity,
