and lift performance to the C-2, and can carry greater payloads over short ranges, up to 20,000 lb, including suspended external loads. The C-2 can only deliver cargo to carriers, requiring further distribution to smaller vessels via helicopters, while the V-22 is certified for operating upon amphibious ships, aircraft carriers, and logistics ships. It could also take some helicopter roles by fitting a 600 lb hoist to the ramp and a cabin configuration for 12 non-ambulatory patients and 5 seats for medical attendants. Bell and P&W designed a frame for the V-22 to transport the Pratt & Whitney F135 engine of the Lockheed Martin F-35. On 5 January 2015, the Navy and USMC signed a memorandum of understanding to buy the V-22 for the COD mission. Initially designated HV-22, four aircraft were bought each year from 2018 to 2020. It incorporates an extended-range fuel system for an unrefueled range, a high-frequency radio for over-the-horizon communications, and a public address system to communicate with passengers; the range increase comes from extra fuel bladders through larger external sponsons, the only external difference from other variants. Its primary mission is long-range logistics; other conceivable missions include personnel recovery and special warfare. In February 2016, the Navy officially designated it the CMV-22B. The Navy's Program of Record originally called for 48 aircraft, it later determined that only 44 were required. Production began in FY 2018, and deliveries start in 2020. The Navy ordered the first 39 CMV-22Bs in June 2018; initial operating capability is anticipated to be achieved in 2021, with fielding to the fleet by the mid-2020s. The first CMV-22B made its initial flight in December 2019. The first deployment began in summer 2021 aboard the USS Carl Vinson. Japan Self-Defense Forces In 2012, former Defense Minister Satoshi Morimoto ordered an investigation of the costs of V-22 operations. The V-22's capabilities exceeded current Japan Self-Defense Forces helicopters in terms of range, speed and payload. The ministry anticipated deployments to the Nansei Islands and the Senkaku Islands, as well as in multinational cooperation with the U.S. In November 2014, the Japanese Ministry of Defense decided to procure 17 V-22s. The first V-22 for Japan undertook its first flight in August 2017 and the aircraft began delivery to the Japanese military in 2020. In September 2018, the Japanese Ministry of Defense decided to delay the deployment of the first five MV-22Bs it had received amid
