An airborne electro-optical laser sensor designed to detect minefields has demonstrated the ability to detect simulated improvised explosive devices. The Airborne Surveillance, Target Acquisition and Minefield Detection System (ASTAMIDS) developed by Northrop Grumman, demonstrated this capability during an Army evaluation of the new system. The system was flown on the MQ-8B Fire Scout unmanned aerial system.

ASTAMIDS combines multi-spectral electro-optical sensors employing different sensing methods, including texture analysis and change detection, to spot recently buried objects suspected as mines or IEDs. In addition to its primary counter-mine and counter-IED mission ASTAMIDS also provides reconnaissance, surveillance and target acquisition capability. The system’s laser can also designate targets for laser guided munitions. Under the Army evaluation the system successfully designated targets for three Hellfire missiles.

Through a recent test series conducted in September 2010, ASTAMIDS flew 12 missions on an Army UH-1 and the Northrop Grumman owned MQ-8B unmanned vehicle. These flight tests evaluated the system’s C-IED nadir step stare, off-nadir road following and large area precision mapping capabilities.

These capabilities were supported by the new ‘ASTAMIDS Ground Exploitation Station’ (AGES), integrated with the systems’ ground control segment for the test. AGES processed streaming telemetry data obtained from the airborne sensor, enabling operators to identify target locations in near real-time.

The core of the system is the gimbaled, lightweight, multi-spectral, electro-optical and infrared imaging sensor designed to be flown on both manned and unmanned aircraft. The airborne payload weighs about 36 kg (80 pounds). Integrated with AGES processors and software, the system detects, locates and identifies ground targets, minefields, obstacles and IEDs, determines ranges to ground targets, and, as proven in the tests, designates targets for attack by laser-guided munitions.

According to the U.S. Army PM Close Combat Systems, “ASTAMIDS will give Army Brigade Combat Teams unprecedented situational awareness and target designation capabilities.” The near-real time response of the system is critical for counter-IED missions, as it provides warfighters with actionable intelligence minutes after a specific area is analyzed.

“These tests proved we’ve achieved our goal with ASTAMIDS – we can identify ground threats and deliver targeting-quality data to adjacent warfighters to destroy the threats and do that in near real time” said Dan Chang, Northrop Grumman vice president of Maritime and Tactical Systems.

The U.S. Air Force completed the final 103rd test flight in the testing for the Automatic Ground Collision Avoidance System (Auto GCAS), part of the Automatic Collision Avoidance Technology (ACAT) /Fighter Risk Reduction Program. Researchers hope the lessons learned during these tests will lead to the virtual elimination of fighter aircraft mishaps.

The cooperative program was conducted by the Air Force Research Laboratory (AFRL) in conjunction with the Air Force Flight Test Center and NASA Dryden. The Auto GCAS flight testing effort has collected data over the course of over 141 flight hours, with more than 1,600 automatic recoveries executed. The F-16 test aircraft will now be transitioned to the Air Force Flight Test Center 416th Flight Test Squadron, who will begin production flight testing in the next phase of the ACAT program. The Auto GCAS software was recently transitioned to Aeronautical Systems Center, with the goal of incorporating the system into F-16 production aircraft in 2014.

Auto GCAS technology uses information gathered from Global Positioning System data and incorporates it with Digital Terrain Elevation Data maps to enable aircraft to reference terrain below. In the event that an aircraft is flown dangerously close to the ground, this critical data enables the aircraft to automatically execute avoidance maneuvers without pilot intervention.

Onboard for the final test flight was Lockheed Avionics Design Engineer Charles Canney and NASA project pilot Nils Larsen. The flight took place over a widespread area including portions of California from Edwards Air Force Base to Death Valley and the peaks and canyons of the Sierra Nevada Range. The flight evaluated the ability of the system to fly at low levels without “nuisance fly-ups,” or unwarranted activations of the system. Additionally, the system’s collision avoidance capability was evaluated with the execution of numerous mishap profiles that are typically seen in the F-16 fleet.

Mr. Canney, who has served as part of the design team for Lockheed since 1989, flew aboard many of the collision avoidance runs throughout this testing effort. He described the final test flight as “the best flight anyone has ever had,” and stated, “As Nils got down low, I could see dirt being kicked up off of the desert floor and no nuisance activations.”

Israel Aerospace Industries (IAI) is unveiling two new unmanned systems, representing a breakthrough in Vertical Take off and Landing (VTOL) unmanned aerial vehicle (UAV) designs. Both designs, named Panther and Mini-Panther employ a new tilt-rotor propulsion concept patented by IAI. Both are designed for tactical use. The Panthers have already performed test flights and are expected to operational ready next year. The new Panther will be displayed tomorrow in Latrun, Israel

Panther combines the flight capabilities of fixed wing airplane with helicopter-like hovering, takeoff and landing, by employing two tilt-rotor propellers, and a vertical lift augmenter propeller providing additional lift for hovering, takeoff and landing. This configuration enables the Panther to be runway-independent, taking off and landing from unprepared areas. This unique, concept can be applied to UAVs of different sizes, providing land forces and special operations units at tactical level the capabilities commonly associated with much larger platforms.

Weighing about 65 kg, the Panther is powered by three electrical motors and packs sufficient power to loiter on missions of up to six hours at an altitude of 10,000 ft. At this altitude operational radius can exceed 60 km. The Panther carries IAI’s MiniPOP multi-sensor electro-optical day-night payload comprising stabilized day and night cameras, laser rangefinder, laser pointer or laser designator. The smaller Mini-Panther is a 12 kg tilt-rotor mini-UAV designed for mission endurance of two hours. This version operates at lower altitudes and carries the miniature ‘Micro-POP’ EO stabilized payload. Both versions are powered by ultra-quiet electrical motors contributing to the Panther’s stealth capability. The Panther’s flight control system is enhanced with automatic transition flight modes controlling the transitions between hovering and forward flight, enabling the Panther to take off and land automatically by a simple click of the operator console, thus eliminating the need for an external pilot. The Panther system employs compact ground control station and support systems packed into a midsize vehicle, storing up to three aircraft, communications datalink, and support equipment, allowing tactical units an autonomous operation. The ground control segment has two operators, using two fully redundant and identical consoles. The two consoles are employed for maximum mission efficiency – according to IAI, the Panther can be operated by a single operator as well. Designed as a portable system, the mini Panther includes two aircraft and a command and control unit carried by two soldiers. The Panther control station, transported on a midsize vehicle, can store up to three aircraft, as well as the ground data link, the support equipment and spare parts, all of which allow the troops’ autonomous operation on the field at a tactical level. Two operators control the mission using two fully redundant identical consoles. IAI is unveiling the Panther tilt-rotor tactical UAV tomorrow, at the Latrun Conference in Israel. IAI’s new UAV will make its international debut later this month, at the Association of the United States Army’s (AUSA) 2010 Annual Meeting and Exposition in the USA.

The Saab group has been awarded a contract to deliver an Airborne Early Warning & Control (AEW&C) system comprising the Saab 2000 aircraft platform equipped with the ERIEYE airborne early warning radar system. The contract comprises a Saab 2000 aircraft equipped with the advanced ERIEYE radar system, ground equipment, logistics and support services, to be delivered over a period of 4.5 years. The identity of the customer has not been released but it is assumed to be one of the Gulf States. The number of aircraft to be delivered has not been released as well.

Earlier this year the UAE has ordered two smaller Erieye AEW systems based on the saab 340 platform. At the time official sources at the UAE explained the w340 is an interim solution, and that the country is still undecided on the long-term plans for its objective AEW capability, considering the Saab 2000, Boeing 737 and Northrop Grumman E-2D. Other nations in the region interested in acquiring AEW capability include Oman and Kuwait.

Another country that could be interested in such capabilities is South Africa where Saab sold the Gripen fighter aircraft and also operates local subsidiaries. In 2008 the use of Erieye was considered to bolster aerial surveillance and security during the World Cup games this year. However, the presence of such aircraft during the games was not reported. According to Saab, the Erieye airborne surveillance system in combination with the ground equipment provide a detailed picture of a situation which can be used in connection with, for example, border surveillance, rescue operations as well as in combating terrorism and organized crime.

“This contract can be seen as a further confirmation of our strong position in the world regarding not only the area of airborne surveillance but in systems integration and data fusion as well, says Håkan Buskhe,” CEO, Saab. “This surveillance system will provide the customer with improved solutions for defense and civil security.”

Saab’s ERIEYE radar is currently operated by the Swedish Air Force and Royal Thai Air Force and the UAE Air Force (on Saab 340 platforms). Brazil, Mmexico and Greece operate it on the Embraer 145 platform. The only Saab-2000 sofar is Pakistan.

On Thursday last week (Sept 30) the Pentagon awarded two competitive contracts for the delivery of advanced targeting pods for U.S. Air Force fighters. The Air Force will continue the procurement of two types of pods under the Advanced Targeting Pod – Sensors Enhancement (ATP-SE) program – the AAQ-33 Sniper from Lockheed Martin and AAQ-28(V) Litening – from Northrop Grumman and Israel’s Rafael. The total spending on the two systems over the life of the program could reach US$2.3 billion. The service is seeking to acquire an estimated 275 systems. At present, the contracts awarded to each of the two teams amount about $23 million each.

Boeing has been awarded a sole-source $11.9 Billion  indefinite-delivery/indefinite-quantity (IDIQ) contract to support the fleet of B-52H bombers operated by the U.S. Air Force for the next eight years. The contract provides for the all acquisition and sustainment activities needed to support the aircraft and its systems, through their life extension and modernization. The award sets the framework for the program with individual orders to be awarded as required.

The B-52 is a long-range, heavy bomber that can perform a variety of missions. The bomber is capable of flying at high subsonic speeds at altitudes up to 50,000 feet (15,166.6 meters). It can carry nuclear or precision guided conventional ordnance with worldwide precision navigation capability.

In a conventional conflict, the B-52 can perform strategic attack, close-air support, air interdiction, offensive counter-air and maritime operations. For example, during Desert Storm in 1991, B-52s delivered 40 percent of all the weapons dropped by coalition forces. It is highly effective when used for ocean surveillance, and can assist the U.S. Navy in anti-ship and mine-laying operations. Two B-52s, in two hours, can monitor 140,000 square miles (364,000 square kilometers) of ocean surface. The aircraft has been equipped with heavy stores adapter beams for carrying 2,000 pound munitions, and a full array of advance weapons currently under development. All B-52s can be equipped for precision attack carrying two electro-optical viewing sensors, a forward-looking infrared and advanced targeting pods to augment targeting, battle assessment, and flight safety, thus further improving its combat ability. Pilots wear night vision goggles to enhance their vision during night operations. Night vision goggles provide greater safety during night operations by increasing the pilot’s ability to visually clear terrain, avoid enemy radar and see other aircraft in a lights-out environment.

The B-52A first flew in 1954, and the B model entered service in 1955. A total of 744 B-52s were built with the last, a B-52H, delivered in October 1962.  The first of 102 B-52H’s was delivered to Strategic Air Command in May 1961. The H model can carry up to 20 air launched cruise missiles. In addition, it can carry the conventional cruise missile that was launched in several contingencies during the 1990s, starting with Operation Desert Storm and culminating  in the early 2000s with Operation Iraqi Freedom, and Operation Enduring Freedom in Afghanistan.

Only the H model is still in the Air Force inventory and is assigned to the 5th Bomb Wing at Minot AFB, N.D. and the 2nd Bomb Wing at Barksdale AFB, La., which fall under Air Force Global Strike Command. The aircraft is also assigned to the Air Force Reserve Command’s 917th Wing at Barksdale.

Bavar-2 amphibian seaplane employs the 'Wing in Ground Effect' (WIG) principle to fly low above sea level. In fact, Bavar-2 traces back to the Russian Eska-1 an early WIG planes designed in the 1970s. It is equipped with maritime surveillance equipment, and communications for recce and target acquisition over the sea. The new plane is operated by the Iranian revolutionary Guards naval units.

Iran is preparing a massive force of small but highly capable combat elements capable of disrupting oil transportation through the Persian Gulf and the Straight of Hurmoz choke point. The Iranians have developed unique operational concepts employing coordinated swarm attacks that could effectively defeat large, well protected surface combatants such as those operated by the allied naval forces present at the Gulf. Many of these Swarm elements are currently stationed at the naval base at Bandar Abbas, acting as the Swarm’s ‘Hornets Nest’ at the southern end of the Hurmoz Straits in the Persian Gulf. In recent, highly publicized naval exercises held by Iran’s Revolutionary Guards’, swarm attacks were demonstrated by engaging targets from extended range by anti-ship missiles, while smaller fast boats were closing in at high speed, firing rockets and Rocket propelled Grenades (RPG) from very short range.

In recent years Iran is escalating its swarm capabilities to higher levels, with the development of indigenous weapons and platforms tailored for the Persian Gulf Theater of operation. Among these elements are mini submarines, amphibian seaplanes, high speed missile boats and medium range anti-ship missiles. All are designed as compact, cost efficient element that together, creating a force multiplier that cannot be ignored even by the world’s largest, most capable navies.

A key element in this ‘hornets nest’ is the Ghadir mini-submarine. The first two locally built subs were delivered in 2008 and this year during a visit at the base four subs were visible. These submarines built for short missions operating at shallow water, carrying out coastal reconnaissance, mine laying and engagement of surface targets, including moving vessels and oil rigs. Mining by submarines could become one of Iran’s modus operandi as detection or attribution of such action to the actual perpetrator is almost impossible.

Another element of the hornets nest was unveiled this week, as Iran’s Revolutionary Guards naval units displayed over a dozen planes during an official visit of the Guards’ commander, brig. General Ahmad vahidi at Bandar Abbas. Unveiled as a prototype in 2006, Bavar-2 is designed to operate as a rapid reaction force, equipped with aerial cameras and communications links transmitting images in real-time to command centers at sea or on land. The seaplane is also equipped with a machine gun. It is flown by a single pilot and is fitted to operate in day or night, using night vision devices.

In August 2010 the Iranians unveiled the ‘sting’ of the hornets – the new Zulfikar fast patrol boats (shown in the video below), an all-aluminum built fast boat armed with Iranian-made Nasr-1 medium range anti-ship missiles. (actually, an Iranian version of the Chinese C-704 missile). The Iranians plan to deploy large numbers of these boats, armed with the locally produced missiles, being able to saturate the defenses of highly protected surface vessels.

The new Bavar-2 Wind in Ground Effect (WIG) amphibian seaplane, designed to perform short range maritime surveillance, coastal patrol and provide target acquisition for the Zulfiqar fast boats, enabling them to launch their missiles at maximum range, thus avoiding counter attack from the surface. As a WIG amphibian, Bavar-2 has unique capabilities to ‘sea skim’ just above wave-top level, or perch at sea level, thus evading detection by hostile radars. Typically, such planes cruise at a speed of 130 km/h and perform optimally at an altitude of few meters above the sea although, technically some WIG designs can reach a maximum altitude of 300 meters.

In times of crisis it is assumed that the fast boats, submarines and seaplanes will disperse to many coastal locations, from where they will be able to launch surprise attacks against merchant ships, tankers or military targets. The submarines and amphibians will provide the eyes and ears for the missile carrying fast fast boats, which could group into attack swarms to strike and disperse immediately after it, thus making it difficult for the enemy to launch an effective counter strike.

Australia is wiring 12 of its new Super Hornets to receive Electronic Surveillance and Attack systems, if and when such capability will be required. Photo: Boeing

Boeing is pre-wiring 12 of the Royal Australian Air Force’s (RAAF) Super Hornet for potential conversion of the aircraft for Electronic Attack role. At present the Australians have not decided whether to equip the aircraft with such capabilities. According to RAAF Group Capt. Steve Roberton, Officer Commanding 82 Wing currently operating these fighters, the ability to introduce an electronic attack capability on part of the Australian Super Hornets provides maximum flexibility for future missions. “Ultimately, if a decision to incorporate an electronic attack option is pursued, it will further expand the broad capability of an already formidable Super Hornet weapon system.” Robertson said.

Pre-wiring prepares the infrastructure on aircraft to feed RF signals, power, and cool the unique payloads associated with electronic surveillance and attack. Pre-wiring will enable a standard Super-Hornet Block II to carry Signals Intelligence (SIGINT) payloads (ALQ-218 radar band and ALQ-227 communications scanners) as well as the ALQ-99 Electronic Attack jammer. Both are currently employed with the U.S. Navy’s F-18G Growler. Australia is the first Super Hornet customer to follow the ‘pre wiring’ track. Boeing completed the production of the first batch of 12 Australian F/A-18E/Fs and is on schedule to deliver the last of the 24h Super Hornets in 2011. According to Boeing’s Australian Super Hornet program manager, Carolyn Nichols, the pre-wired configuration reduces the cost associated with future retrofit at a later date”

The 24 F/A-18E/F Block II Super Hornets ordered by Australia in 2007 are multirole aircraft, able to perform virtually every mission in the tactical spectrum, including air superiority, day/night strike with precision-guided weapons, fighter escort, close air support, suppression of enemy air defenses, maritime strike, reconnaissance, forward air control and tanker missions. Adding an Electronic surveillance and Attack capabilities will dramatically enhance the nation’s cyber-warfare potential to engage future adversaries with non lethal but highly effective, means.
