USAF DRONE - GLOBAL HAWK RQ-4 - CLOSE UP LOOK AT MECHANICS WORKING ON ENGINES

The RQ-4B & MQ-4C:

The Northrop Grumman RQ-4 Global Hawk is a high-altitude long-endurance (HALE) Intelligence, Surveillance, and Reconnaissance (ISR) UAV/UAS. The Global hawk is powered by a single Rolls-Royce AE 3007H (military desig-nation is F137-RR-100) Turbofan engine with 8,600 pounds of thrust.

Cruising at extremely high altitudes of up to 65,000 feet (19,800 meters), the RQ-4 can survey large geographic areas with pinpoint accuracy, providing real-time information about the location of the enemy as well as resources and personnel. When mission parameters are programmed into the Global Hawk, it can autonomously taxi, take off, fly, remain on station, return, and land. No actual remotely piloted flying takes place. Ground-based operators monitor the RQ-4's health and status, and can alter navigation and sensor plans during flight when necessary.

The now retired RQ-4A was an imagery-intelligence (IMINT) UAS designed to carry a 2,000 pound payload. The RQ-4A has one configuration - the Block 10. The Block 10 employs an IMINT system comprised of a synthetic aperture radar (SAR) sensor and an EO / IR sensor. In 2011, the last of seven RQ-4As was retired from the Air Force inventory. The RQ-4B, the successor to the RQ-4A, is designed to carry 3,000 pounds of payload and enable multi-intelligence (multi-INT) collecting. The RQ-4B has three configurations: Block 20, Block 30, and Block 40. The Block 20 employs upgraded SAR and EO/IR sensors in an IMINT-only configuration, however, four Block 20 aircraft were subsequently converted to EQ-4B communication relay platforms (three still active), carrying the Battlefield Airborne Communication Node (BACN) payload. The Block 30 employs the same SAR and EO/IR sensors as the Block 20 and integrates a wide spectrum signals intelligence (SIGINT) sensor, the Airborne Signals Intelligence Payload (ASIP). SAR, EO/IR and ASIP are used simultaneously to create a multi-INT platform. Eighteen Block 30 UAS are currently fielded. The Global Hawk Block 40 is equipped with the multi-platform radar technology insertion program (MP-RTIP) Active Electronically Scanned Array (AESA) radar, which provides wide-area surveillance of stationary and moving targets. The MP-RTIP sensor allows military commanders to gather near real-time imagery of moving targets. Eleven Block 40 UAS are currently fielded. Block 40 Initial Operational Capability (IOC) is projected for 2015. In 2014, an RQ-4 Block 40 flew for 34.3 hours, setting a new endurance record for longest unrefueled flight by a U.S. Air Force aircraft.
