Four MV-22 Ospreys to be built for Japan


20 Jul, 16, Source: US DoD

The following statement from the US Dept of Defense yesterday indicates that four MV-22 Ospreys are to be built for Japan, with the wording carefully crafted due to the way that the Far Eastern country had regarded their defence operations since 1954 – for example, they use “Air Self-Defence Force” in place of “Air Force” for example.

Bell-Boeing Joint Project Office, Amarillo, Texas, is being awarded a $544,668,978 modification to the previously awarded fixed-price-incentive-firm target, Lot 17-21 multi-year contract (N00019-12-C-2001).  This modification provides for the long lead production materials and the manufacture and delivery of four MV-22 tilt rotor aircraft pursuant to the variation in quantity clause in support of the government of Japan; as well as incorporation of an engineering change proposal for the standby flight display.  Work will be performed in Fort Worth, Texas (24.6 percent); Ridley Park, Pennsylvania (19.2 percent); Amarillo, Texas (10.4 percent); Dallas, Texas (4.3 percent); East Aurora, New York (2.5 percent); Park City, Utah (1.7 percent); El Segundo, California (1.3 percent); Endicott, New York (1 percent); Ontario, Canada (0.9 percent); Tempe, Arizona (0.8 percent); Corinth, Texas (0.8 percent); Rome, New York (0.7 percent); Torrance, California (0.7 percent); Luton, United Kingdom (0.6 percent);  Los Angeles, California (0.6 percent); Cobham, United Kingdom (0.6 percent); Irvine, California (0.6 percent); San Diego, California (0.5 percent); Yakima, Washington (0.5 percent); Brea, California (0.5 percent); Rockmart, Georgia (0.5 percent); Albuquerque, New Mexico (0.4 percent); Whitehall, Michigan (0.4 percent); Wolverhampton, United Kingdom (0.4 percent); Tucson, Arizona (0.4 percent); Erie, Pennsylvania (0.3 percent); Vergennes, Vermont (0.3 percent); Kilgore, Texas (0.3 percent); Shelby, North Carolina (0.3 percent); Avon, Ohio (0.2 percent); Santa Clarita, California (0.2 percent); Garden City, New York (0.2 percent); El Cajon, California (0.2 percent); Sylmar, California (0.2 percent); Westbury, New York (0.1 percent); and various other locations inside and outside the U.S. (22.8 percent), and is expected to be completed in May 2020.  Foreign military sales funds in the amount of $302,913,946 will be obligated at time of award, none of which will expire at the end of the current fiscal year.  The Naval Air Systems Command, Patuxent River, Maryland, is the contracting activity.

V-22 Osprey


Japan became the first export customer of this tiltrotor transport. A contract for delivery of 17 Ospreys was announced in 2015. Other countries like India, Israel, South Korea and United Arab Emirates also expressed interest in obtaining these machines.

  The Osprey has greater speed, range and lift capability over conventional helicopters. It can operate from ships, as well as from the rough frontline airfields. It can carry 9 000 kg internally or 6 800 kg externally. The MV-22A operated by the US Marine Corps accomodates up to 24 troops, or 12 litters and medical attendants. The Osprey can carry various combinations of troops, weapons or vehicles. In the near future the Osprey will be capable of refueling other aircraft and helicopters in the air.

  This machine can be armed with 7.62-mm or 12.7-mm machine guns, or 7.62-mm minigun on its ramp. A gun turret system was also developed and integrated in its belly, but was found of limited use. A Gatling gun under the nose is planned for the future upgrades. Also there are plans to equip the V-22 with of air-to-ground missiles like Hellfire or Griffin on its wing hardpoints.

The Remote Guardian System is an add-on kit that is mounted under the belly and it is retractable.

It has two turrets, a gun turret with a 7.62mm minigun and a FLIR type sight turret in front of it. The system is controlled from a display and a playstation type hand controller. Source

  Mounted in wingtip nacelles, the engines can be swiveled through 97.5° and drive three-bladed prop-rotors through interconnected drive shafts. It takes just 12 seconds fro the nacelles to swivel and switch between helicopter and aircraft modes. For shipboard stowage, the main planes pivot centrally to rotate along the fuselage top, the prop-rotor blades also folding in parallel.
