2.1.2 RQ-2B Pioneer
User Service: Marine Corps Manufacturer: Pioneer UAV, Inc.
Background: The Navy/Marine RQ-2B Pioneer has served with Navy, Marine, and Army units, deploying aboard ship and ashore since 1986. Initially deployed aboard battleships to provide gunnery spotting, its mission evolved into reconnaissance and surveillance, primarily for amphibious forces. Launched by rocket assist, pneumatic launcher, or from a runway, it recovers on a runway with arresting gear after flying up to 5 hours with a 75 pound payload. It currently flies with a gimbaled electro-optical/infra red (EO/IR) sensor, relaying analog video in real time via a C-band line-of-sight (LOS) data link. Since 1991, Pioneer has flown reconnaissance missions during the Persian Gulf, Bosnia, and Kosovo conflicts. It is currently flying in support of Marine Forces in OIF. The Navy ceased Pioneer operations at the end of FY02 and transferred assets to the Marine Corps. The Marine Corps is sustaining the Pioneer to extend their operations with it until replaced by a follow-on vertical UA.

2.1.3 RQ-4 Global Hawk
User Service: Air Force Manufacturer: Northrop Grumman Inventory: 12 Delivered/58 Planned (7 ACTD + 51 Production aircraft)
Background: The Air Force RQ-4 Global Hawk is a high altitude, long endurance UA designed to provide wide area coverage of up to 40,000 nm2 per day. The size differences between the RQ-4A (Block 10) and RQ-4B (Blocks 20, 30, 40) models are shown above. Global Hawk completed its first flight in February 1998 and transitioned from an ACTD into engineering and manufacturing development (EMD) in March 2001. Global Hawk carries both an EO/IR sensor and a Synthetic Aperture Radar (SAR) with moving target indicator (MTI) capability, allowing day/night, all-weather reconnaissance. Sensor data is relayed over CDL LOS (X-band) and/or beyond-line-of-site (BLOS) (Ku-band SATCOM) data links to its mission control element (MCE), which distributes imagery to up to seven theater exploitation systems. The Air Force has budgeted for 34 production aircraft in FY05-10, and plans a total fleet of 51. The first of 44 ‘B’ models is to be available for flight test in November 2006. The first Mult-Int payload which includes Advanced Signals Intelligence Program (ASIP) will be available for flight test in May 2007 followed by the Multi-Platform Radar Technology Insertion Program (MP-RTIP) payload in July 2007. The Air Force plans to add other sensor and communications capabilities in a spiral development process as this fleet is procured. Ground stations in theaters equipped with the common imagery processor (CIP) will eventually be able to receive Global Hawk imagery directly. IOC for imagery intelligence (IMINT)-equipped aircraft is expected to occur in FY06. http://www.af.mil/factsheets/factsheet.asp?fsID=175.
