C-23 Sherpa

The Sherpa is an all-freight version of the Shorts 330 regional airliner with a 5 ft-6 inch square cabin section over an unimpeded hold length of 29 ft. Through-loading is provided via a large forward freight door, and via a full width, hydraullically operated rear ramp door with removable roller conveyors. The C-23 Sherpa is the Army National Guard旧 answer to missions requiring an aircraft that is capable of faster, higher-altitude and longer-distance coverage than helicopters. The Sherpa comes with a low operating cost due to its simple, robust construction, compared to that of other cargo aircraft.

The Army National Guard has procured 44 C-23B/B+ Sherpa light cargo aircraft to support theater aviation, cargo, airdrop, and aeromedical evacuation for both state and federal wartime missions. The C-23 multi-role utility airplane is the only cargo airplane in the Army, and is organized into 4 theater airplane companies. Each company has four detachments. The detachments are all located in different states. Each detachment has two aircraft. In the Alaska Army National Guard the UV-18As have been replaced by the C-23B+. Requirements exist to standardize C-23B/B+ systems to include global positioning systems, high frequency radios, airdrop equipment, aeromedical evacuation, and engine upgrades. A few of these aircraft are used as all-freight regional airliners by Air Force Material Command.
The aircraft can carry up to 30 passengers in airline-type seats, along with palletized cargo, four small pallets, and do airdrop of those pallets, or 18 litter patients plus their medical personnel. It has a range of a thousand miles, cruises up to two hundred knots, and it旧 square because most of the things the Army has are square rather than round. It has six-and-a-half feet of headroom. It is unpressurized, but if it flies above 10,000 feet for an extended period of time, the crew wears oxygen masks. The Sherpa has a crew of three, but sometimes flies with four man crews if there is a need for two flight engineers.


The C-23B Sherpa aircraft is a light military transport aircraft, designed to operate efficiently, even under the most arduous conditions, in a wide range of mission configurations. The large square-section hold, with excellent access at both ends, offers ready flexibility to perform ordnance movement, troop & vehicle transport, airborne/airdrop missions, medical evacuation and is suitable for conversion to other specialist duties such as maritime or land surveillance.

Configured as a troop transport, the Sherpa provides comfortable, air-conditioned seating for 30 passengers, features "walk about" headroom, a removable latrine unit, and has a 500 lb capacity / 345 cu. ft. baggage compartment located in the nose of the aircraft. Additional space for a 600 lb capacity optional baggage pallet is provided on the rear ramp of the aircraft.

During airborne operations, the aircraft accommodates 27 paratroopers. Optionally, it can be outfitted to handle up to 18 stretchers plus 2 medical attendants. The airplane meets Army Short Take-off & Landing guidelines (STOL), can operate from unpaved runways and is equipped with self-contained ground handling equipment. Operational experience with this remarkable aircraft has proven it to have low maintenance costs and low fuel consumption.

The grey, 30-foot long Sherpa, begins life as a Shorts 360 Airliner. The Shorts Aviation Company is located in Belfast, Northern Ireland, and is one of the oldest aircraft builders in the world. The airplanes are then sent to Clarksburg, West Virginia, where each is remanufactured into an Army Sherpa. The West Virginia Air Center (WVAC) operated by Bombardier Defence Services Inc. provides Contractor Logistics Support (CLS) for the C-23 Sherpa aircraft operated by the United States Army National Guard (USARNG) and the US Air Force. This entails support of 27 C-23B and C-23B+ aircraft located at 19 different bases in the USA, Puerto Rico and the US Virgin Islands. Additionally, the company provide CLS to the fleet of C-23A aircraft operated by the Air Force Test Pilot School at Edwards Air Force Base CA.

US Army Aviation Technical Test Center (USAATTC) has a C-23A aircraft which has been modified to acquire various electronic sensor data in support of the Program Executive Officer (PEO) Intelligence and Electronic Warfare Programs. The Sherpa (C-23A) is owned by Aviation Technical Test Center (ATTC), Ft. Rucker, AL. Originally under the sponsorship of PM, Airborne Reconnaissance Low (PM ARL) and currently being transitioned to PM NV/RSTA, it acts as a UAV surrogate for payload testing. The C-23A Sherpa, with its on-board workstation and capability to carry observers, is ideal for real-time evaluations of various sensor and target detection/recognition systems.

美國陸軍C-23“夏爾巴人”運輸機

　　國際線上消息：英國《簡氏防務週刊》2005年8月31日刊報道，美國陸軍發佈了關於現貨採辦取代其現有老化的固定翼運輸機機隊的更多細節，包括與早期的計劃相比對裝載能力要求有所降低。陸軍的"未來貨運飛機(FCA)"現在預計載貨量降為5450千克，而早期文件中要求的是8200千克。陸軍還增加了預計購買的飛機數量。

　　根據參加FCA競爭的一支由EADS北美公司和雷聲公司組成的小組的官員說，這一新計劃的細節使他們對自己提出的用相同座艙的CN-235和C-295組成混合機隊的方案更有信心了。他們的主要競爭對手是由阿萊尼亞北美公司與L-3通信公司組成的小組，他們的解決方案是C-27J"斯巴達人"飛機。

　　根據陸軍FCA的有關文件，陸軍希望FCA承擔後勤補給、傷員撤離、部隊移動、空降作戰、人道援助等任務以及國內的"國土安全"任務。陸軍計劃用FCA來取代大部分C-23"夏爾巴人"飛機，但是最近計劃的範圍擴大到包括替換C-26偵察飛機和部分C-12"空中國王"(King Air)運輸機。

　　美國陸軍航空和導彈司令部的官員稱，下一個五年中購買33架飛機的資金已經到位，陸軍希望最終購買145架。陸軍計劃在10月份發佈正式的方案徵詢書，並在2006財年年底授予合同。根據最新的有關文件，陸軍計劃在2007財年購買3架飛機，然後在隨後的三年中依次購買4架、7架和8架飛機。
