The attributes that make the use of unmanned preferable to manned aircraft in the above three roles are, in the case of the dull, the better sustained alertness of machines over that of humans and, for the dirty and the dangerous, the lower political and human cost if the mission is lost, and greater probability that the mission will be successful. Lower downside risk and higher confidence in mission success are two strong motivators for continued expansion of unmanned aircraft systems.

2.0 CURRENT UAS
This Section provides condensed descriptions of current and planned DoD UAS efforts for the users of this Roadmap. It categorizes DoD’s UAS as Major UAS, Concept Exploration (those being used to develop new technologies or operating concepts), Special Operations (those UAS unique to SOCOM), Small (those mini and micro UAS that can be operated by 1-2 people), and Unmanned Airships (aerostats and blimps).  Detailed descriptions are available at the websites listed with specific systems below.
Figure 2.0-1 presents a consolidated timeline of the Services’ ongoing and planned programs of record for tactical, endurance, and combat UAS.  The vertical line on each program’s bar represents actual or projected initial operational capability (IOC).  This Figure is a key component of the overall UAS Roadmap for the next 25 years, shown in Figure 6.2-1.

2.1 MAJOR UAS
2.1.1 MQ-1 Predator
User Service: Air Force Manufacturer: General Atomics Aeronautical Systems Inc. Inventory: 120+ (All types) Delivered/77 Planned

Background: The Air Force MQ-1 Predator was one of the initial Advanced Concept Technology Demonstrations (ACTDs) in 1994 and transitioned to an Air Force program in 1997.  Since 1995, Predator has flown surveillance missions over Iraq, Bosnia, Kosovo, and Afghanistan.  In 2001, the Air Force demonstrated the ability to employ Hellfire missiles from the Predator, leading to its designation being changed from RQ-1 to MQ-1 to reflect its multi-mission capability.  The Air Force operates 12 systems in three Predator squadrons.  The MQ-1 fleet reached the 100,000 flight hour mark in October 2004, and was declared operationally capable (IOC) in March 2005.
