C-26 Metroliner

The C-26 is operated exclusively by the Air and Army National Guard and was first delivered in 1989. They have quick change passenger, medevac, or cargo interiors. The C-26A is the civilian equivalent of the Fairchild Metro III with the C-26B being equivalent to the Fairchild Metro 23. The C-26B(CD) [Counter Drug] and the UC-26 are National Guard Bureau aircraft used to support the Air National Guard in drug control operations. The UC-26C is a derivative of the Fairchild Merlin IVC. The C-26B provides time-sensitive movement of personnel and cargo, as well as limited medical evacuation. The UC-26C provides support to counter drug (CD) operations. Additionally, up to ten ANG C-26Bs are being modified to carry specialized electronic equipment used to support CD operations.

The C-26 aircraft, manufactured by Fairchild Aircraft Incorporated, is a high performance, fixed wing, pressurized, twin engine turboprop that has accomodations for a pilot and a co-pilot and 19 passengers and/or cargo or a combination of both. It is powered by two Garrett TPE331-12URH engines, rated at 1100 shaft horsepower (820 kw) takeoff power and 1000 shaft horsepower (746 kw) maximum continuous power and equipped with 106 inch (269 cm) diameter McCauly full feathering, reversible, constant speed four bladed propellers.

The aircraft represents an on-call, rapid response, modern air transport for high priority resupply and movement of key personnel to remote, unserviced or feeder sites. Specifically, the aircraft is used to deliver repair parts, equipment, technical teams, crash and accident investigation teams. In its role, such functions as range clearance, Medical Evacuation (MEDEVAC), administrative movement of personnel, transportation connections and courier flights are accomplished.

The C-26 Contractor Logistics Support (CLS) Follow-On Acquisition effort in 1997 focused on providing full CLS for 32 Air National Guard (ANG) and Army National Guard (ARNG) C-26B aircraft and 1 ANG UC-26C aircraft. The C-26 Program Office used acquisition streamlining initiatives to remove all Military Standards & Specifications (MIL STDs/SPECs) from the RFP. The RFP Support Office was employed to support the C-26 program. The team also reduced government-mandated Contract Data Requirements Lists (CDRLs) from 22 to 4, and substituted a performance-based Statement of Objectives (SOO) for a Statement of Work (SOW). The requirement was designed to conform to Federal Aviation Administration certifications and standards, creating a high level of interest and competition within the commercial industry. These efforts resulted in program cost avoidance of approximately $33.4M.

On 23 January 1998 the US Air Force Aeronautical Systems Center Reconnaissance Systems Program Office (ASC/RAKBL) awarded a $5,489,211 contract to Versatron Corp. for a replacement Forward Looking Infrared (FLIR) System for the Air National Guard C-26B Aircraft. The system is a third generation detector technology, non developmental item consisting of eleven installed and fully integrated systems and two complete spares. The FLIR system includes a Thermal Imaging System (TIS), color TV and Laser Range Finder all co-located in a single gimbal turret, plus any separate associated electronic units. The turret fits in the existing pod and weighs less than 145 pounds. The total system including the turret, electronic units and cabling weighs less than 285 pounds. The turret rotates a full 360 degree in azimuth field of regard and elevation coverage above 0 degree level elevation and beyond -90 degrees (NADIR). The FLIR is able to receive azimuth and elevation cue commands. The Modulation Transfer Function (MTF) and Noise Equivalent Temperature Difference (NETD) combined must result in a Minimum Resolvable Temperature Difference (MRTD) that provides thermal sensitivity and spatial resolution to detect and recognize a .5m x 2m man size target from other thermal sources or the background at 30,000 feet slant range under clear visibility weather conditions.

C-17戰略運輸機 C-130戰術運輸機

舊消息:

　國際線上消息：據法國《航宇防務》2006年3月24日報道，美陸軍和空軍3月17日宣佈將聯合研製新型運輸機，以加強兩個軍種的戰備。這種新型運輸機預計將在兩年內部署。


美國國防部官員透露，3月17日“採辦戰略報告”一經簽署，陸、海軍立即發佈了建議徵尋書。負責飛機採辦的聯合項目辦公室由陸軍牽頭，兩個軍種將派人員參加。

　　對於美空軍而言，此舉不只是意味著空軍將根據陸軍的需要調整其逐漸老化的機隊，還意味著空軍自身也對輕型運輸機有需求。這不僅是空軍轉型的需要，也是更好地完成本土防禦任務和提供災難救援的需要。空軍官員稱，新型運輸機的部署將為聯合部隊指揮官提供關鍵能力。59年來，空軍一直負責跨戰區空運。而過去的40年來，這一任務基本上都是由C-130戰術運輸機完成的，雖然C-17戰略運輸機也執行有限的跨戰區空運任務。空軍使跨戰區運輸機機型多樣化的工作長期停滯，主要挑戰在於空軍很難以有限的經費完成運輸機機隊的轉型，滿足包括陸軍在內的各個軍種以及戰區指揮官的需要。新型運輸機的部署是空軍迎接這一挑戰的重要一步。

　　對於陸軍而言，新型運輸機將取代老化極其嚴重的C-23“夏爾巴人”、C-12和C-26運輸機。雖然美國空軍在執行戰役和戰略性跨戰區空運方面具有世界領先能力，但是戰場的變化、旅戰鬥隊的模組化以及後勤保障概念向“推動系統”的轉變，都要求陸軍擁有額外的跨戰區運輸裝備，完成最後的戰術機動。空軍不承擔戰術空運任務，這一任務目前由戰術輪式車輛和直升機完成。由於兩個軍種有著相似的能力缺口，因此合作研製新型運輸機就是自然而然的了。空軍和陸軍已經達成協定，兩軍裝備的新型運輸機將採用相同的平臺。
