UAV
Weaponised, man-transportable Micro UAVs
By Mike Hanlon
March 14, 2006) Military conflict over the millennia has been defined largely by the technologies available – the spear, the sword, the horse, gunpowder, rifles, cannons, motorised transport, tanks, the anti-tank and anti-personnel mine, aircraft, rockets and so on. One of the coming capabilities capable of offering a massive advantage in warfare involves robots, sometimes guided and sometimes autonomous that walk, carry, roll, swim and fly. The first UAVs were used to improve situational awaereness and this has quickly evolved – now all but the smallest UAVs have been armed and found to be very effective at delivering precision firepower. The Tactical Aerospace Group (TAG) is about to reveal a new class of weaponised UAV that will be particularly useful for brigade level and down. Initially designed with the ability to be transported through a jungle environment for use in drug interdiction, the TAG UAVs can accompany spec-op teams, be carried over severe terrain and can be fitted with recoilless firearms, new technologies such as Metal Storm and up to 70mm rockets/missiles adapted from existing shoulder launched weapons.

Fire Scout UAV completes first autonomous ship landings
By Mike Hanlon
January 22, 2006 A new chapter in naval aviation history was rewritten this week when two RQ-8A Fire Scout unmanned aerial vehicles (UAV) completed nine autonomous shipboard landings on board USS Nashville (LPD 13). It is the first time a UAV has performed vertical landings on a moving ship without a pilot controlling the aircraft. The RQ-8A is a test version of the newer MQ-8B Fire Scout being developed by Northrop Grumman for the Navy and the U.S. Army. The MQ-8B Fire Scout is the aircraft element of a complete system called the Vertical takeoff and landing Tactical Unmanned Aerial Vehicle (VTUAV) system. Read More
A160 Hummingbird unmanned rotorcraft can loiter for 24 hours
By Mike Hanlon
December 7, 2005 Boeing’s A160 Hummingbird unmanned rotorcraft made its first test flight using a six cylinder Subaru engine on November 30. The new A160 successfully flew for about 30 minutes in the vicinity of an airfield near Victorville, California, bringing the total number of A160 test flights to 32 and the total number of flight hours to 58. The Hummingbird features a unique optimum speed rotor technology that significantly improves overall performance efficiency by adjusting the RPM of the rotor system at different altitudes, gross weights and cruise speeds. It is designed to fly autonomously, for much longer periods of time (in excess of 24 hours), over greater distances (2,500+ nautical miles), at higher altitudes (up to 30,000 feet), and much more quietly than current helicopters.

X-50A Dragonfly Canard Rotor/Wing prototype completes hover flight
By Mike Hanlon
December 6, 2005 Boeing’s second canard rotor/wing (CRW) X-50A Dragonfly unmanned air vehicle (UAV) has successfully completed a four-minute hover flight at the U.S. Army’s Yuma Proving Ground reaching an altitude of about 20 feet above ground. The aircraft combines the vertical takeoff/landing capabilities of a rotorcraft with the high-subsonic cruise speed and agility of a fixed-wing airplane. As its name implies, its versatility is achieved by having a specially designed rotor for vertical takeoffs and landings that can be stopped in flight to serve as a fixed wing for jet cruise. Under an agreement with DARPA, Boeing Phantom Works has built and flight-tested two pilotless demonstrators to assess and validate the advanced rotorcraft concept and according to Clark Mitchell, Boeing Phantom Works program manager for the CRW prototype, the flight was “a significant achievement toward validating the new stopped-rotor technology.” Read More
Global Hawk UAV gets bigger and more capable
By Mike Hanlon
November 11, 2005 The Global Hawk UAV was still in its development stages when the needs of the war in Afghanistan saw it pressed into service. Since then, Global Hawk has successfully completed more than 225 missions through three deployments and more than 4,900 combat flight hours. Now the aircraft has been redesigned to carry 50% more payload, so the Air Force can install additional sensors, enhancing its ability to simultaneously collect imagery, signals intelligence and infrared and radar information, and transfer it to the warfighting machine in near-real time. Global Hawk flies autonomously at an altitude of more than 60,000 feet, above inclement weather and prevailing winds, for 35+ hours at a time. During a single mission, it can provide detailed intelligence, surveillance and reconnaissance information in near-real time over 40,000 square miles - approximately the size of Illinois. Read More
UAVs get smaller: the Micro Air Vehicle nears readiness
By Mike Hanlon
October 26, 2005 As the conflicts in Afghanistan and Iraq have unfolded, one of the new stars in the theatre of battle has been the Unmanned Aerial Vehicle (UAV). As each new conflict redefines war based on the technologies coming of age at that time, the Iraq campaign has seen the coming of age of the UAV in its many wonderous forms. It is the most-requested capability among combatant commanders and in the last 18 months, UAV numbers in Iraq have jumped from fewer than 100 to more than 400 and there are now nearly 600 UAVs in the Afghanistan and Iraq theatres. Even more interesting is the dizzying array of unmanned aircraft used in traditional intelligence, surveillance and reconnaissance UAV roles. Now we’re set to see UAVs get smaller – much smaller. The United States Future Combat Systems (FCS) program recently passed a significant milestone in its progress toward selecting a Class I Unmanned Aerial Vehicle (UAV) system. The MAV has achieved a technology readiness level 6 and is now ready to begin transitioning the technology to the FCS program as an affordable backpackable systems suitable for dismounted soldier, Marine, and Special Forces missions. It will focus on the development of lift augmented ducted fan MAVs to accomplish unique military missions, particularly the hover and stare capability in restricted (e.g urban) environments to provide real-time combat information.

BAE VTOL UAV impresses in autonomous tests
By Mike Hanlon
September 7, 2005 BAE Systems has achieved its first autonomous, untethered flight of its third-generation ducted-fan unmanned aerial vehicle. The company's vertical takeoff and landing (VTOL) air vehicle completed a course of 10 waypoints at BAE Systems' Southern California flight test facility. The seven-minute flight of the IAV2 ducted-fan air vehicle demonstrated a pre-programmed flight plan that included automatic takeoff, waypoint navigation with multiple groundspeeds and altitudes, and loitering and automatic landing. The demonstration flight was achieved just 10 days after the air vehicle's first flight and was the 14th flight of the IAV2. Flights were conducted at temperatures of up to 109 degrees, equating to density altitudes approaching 7,000 feet, in winds of nearly 15 knots. Read More
X-45A Unmanned Combat Aircraft graduate with flying colours
By Mike Hanlon
August 11, 2005 – Two Boeing Joint Unmanned Combat Air Systems (J-UCAS) X-45A unmanned aircraft successfully completed a graduation exercise when they flew their most challenging simulated combat mission to date earlier this week at NASA's Dryden Flight Research Center at Edwards Air Force Base in California. For test flights 63 and 64, the X-45As departed from the base, climbed to altitude, and autonomously used their on-board decision-making software to determine the best route of flight within the "area of action" or AOA. The pilot on the ground approved the plan and the two unmanned vehicles entered the AOA, a 30 by 60 mile area within the test range, ready to perform a simulated Preemptive Destruction-Suppression of Enemy Air Defenses mission. The mission involved identifying, attacking and destroying pre-identified ground-based radars and associated missile launchers before they could be used to launch surface-to-air missiles. During the test flight, the X-45A unmanned aircraft faced a simulated "pop-up" threat, used evasive maneuvers to avoid it, and autonomously determined which vehicle held the optimum position, weapons and fuel to attack the higher priority simulated target. Once the pilot authorized the attack, the unmanned aircraft simulated dropping weapons on the target. After engaging and destroying a second simulated target, the two X-45As completed their mission and safely returned to Edwards. Read More

Boeing X-45A Unmanned Aircraft Demonstrates Autonomous Capability
By Mike Hanlon
June 25, 2005 The Boeing X-45A unmanned aircraft continues to impress in trials as it showcases its ability to adapt to a realistic and changing wartime operational environment. During a recent test flight, its 52nd to date, an X-45A departed from NASA’s Dryden Flight Research Center at Edwards Air Force Base in California, climbed to 29,000 ft. and entered the base’s test range. While flying the mission, several simulated Surface-to-Air Missile (SAM) emitters were activated and the unmanned aircraft autonomously created its own flight plan to remain out of lethal range of the simulated SAM sites. Always managed by the pilot-operator, the X-45A then attacked its simulated priority ground target and showcased the ability to suppress enemy air defenses. Once the aircraft had conducted a simulated battle damage assessment, the X-45A safely returned to Edwards. Read More
ScanEagle UAV passes 3000 combat hours in Iraq
By Mike Hanlon
June 6, 2005 – ScanEagle, a long-endurance fully autonomous unmanned aerial vehicle (UAV) has surpassed 3,000 combat flight hours during operations in Iraq in just ten months. The low-cost UAV has proven to be one of the military's most effective tools for intelligence, surveillance and reconnaissance (ISR) in Iraqi. Since being deployed by the First Marine Expeditionary Force in August 2004, ScanEagle has accumulated flight hours at an increasingly high rate due to the need for its unmatched capabilities. "The Marines depend on ScanEagle daily to provide critical real-time imagery tactical commanders can use to develop a clearer picture of the battlefield," said Peggy Holly, Boeing ScanEagle program manager. "Reaching 3,000 combat flight hours in such a short time is a testament to ScanEagle's operational value." Read More
The networked battlefield moves a step closer
By Mike Hanlon
June 1, 2005 The network centric battlefield moved a step closer this week with the first live-fire testing of the Quick Reaction Unitary (QRU) Army Tactical Missile System (ATACMS) using a network centric integrated High Mobility Artillery Rocket System (HIMARS) launcher. If it sounds complex, that’s because it is, but the big idea is to save time when a time-critical target is identified in the battle space. The test went like this: an Unmanned Aerial Vehicle (UAV) identified a Time Sensitive Target (TST), relaying the information to the proper system node in order to generate a "call-for-fire" message to a Battle Command Cell (BCC) prototype. The BCC prototype provides embedded battle command capabilities, including command and control, situational awareness and direct sensor feeds of target imagery. The UAV provided geographic location data to the BCC, which then ordered a fire mission for an ATACMS QRU off the network-integrated HIMARS launcher, significantly reducing the time to hit the target. The test proved that in those defining moments when seconds matter, a directly networked HIMARS firing ATACMS in the command and control structure will prove to be a considerable force multiplier.
