04 Oct 18. Kestrel Block II Wide-Area Sensor, Exhibited at AUSA Expo. Logos Technologies announced today that it has concluded the very first sale of its exportable aerostat-mounted Kestrel Block II sensor to a military customer. The name of the customer and the total number of systems included in the contract have not been disclosed. Exhibited at the upcoming Association of the United States Army (AUSA) expo, in Washington, D.C., Kestrel Block II is a lightweight (under 85 pounds, or 36kg) version of the Kestrel wide-area motion imagery (WAMI) system, which has proven itself with U.S. forces in both Iraq and Afghanistan.
“Like the original Kestrel, the Block II can image a city-sized area all at once, day and night, once per second,” said John Marion, president of Logos Technologies. “And since it is mounted on an aerostat, it can deliver that ISR capability for days and even weeks at a stretch for true persistent surveillance and full situational awareness.”
The Kestrel Block II has a 360-degree view of its roughly 115sq km coverage area and can detect all significant movers within the scene, all in real-time. The WAMI system can also cue a high resolution, full-motion video camera and guide it to an object or area of interest for close-in inspection.
“Besides following movers in real time, the system also records all the imagery,” Marion explained, “so the Kestrel Block II operator can go ‘back in time’ from an event and see where those involved came from, all the other people they were connected to, and in turn, those people’s actions and connections.”
Redkite-I now official offering with Insitu UAS
In addition to the Kestrel Block II and other systems, Logos Technologies will be displaying its Redkite-I WAMI sensor at AUSA. Redkite-I weighs less than 25 pounds, or 11 kg, and is compact enough to fit inside the payload bay of the Insitu Integrator tactical unmanned aircraft system (UAS).
“Our soldiers deserve the very best, to include the most capable and reliable tactical UAS,” said Don Williamson, Vice President and General Manager Insitu Defense. “Insitu is proud to work with Logos to continue to expand the technologies available to serve our customers.”

04 Oct 18. The newest addition to a line of high-performance SWIR cameras developed by Quantum Imaging (a SCD USA subsidiary) – the high definition SWIR camera QI-SWIR-HD10 – will be introduced at the October Washington DC AUSA convention. This SWIR HD camera’s superior laser see-spot performance, reliability under all battlefield conditions and low SWaP make it suitable for use in a variety of military and industrial applications, including laser beam profiling, semiconductor and solar cell production, enhanced vision and persistent surveillance.
With SCD’s latest Low SWaP 10μm pixel pitch detector, advanced programmable on-chip features and a very low noise performance, the QI-SWIR-HD10 camera provides extended spectral range, a full-frame 2-Dimensional capture and X-Y position of short duration laser pulses in both daytime and nighttime. Multiple asynchronous spots events can be tracked in the same FOV. This capability is completely independent of imaging, assuring optimal imaging capability with laser spot detection.
“Our new SWIR HD camera’s performance, reliability and low SWaP make it ideal for use in a variety of military and industrial applications including laser beam profiling, semiconductor and solar cell production, enhanced vision and persistent surveillance”, explains David Gardner, QI Executive VP.
Following the successful alliance of eight months ago between SCD.USA Infrared, LLC (SCD.USA-IR) and Quantum Imaging, Quantum lately announced its expansion in space and investment in manufacturing and test equipment infrastructure, a growth that allows additional capacity in manufacturing, engineering and customer support.
“The combination of the larger space with SCD investments in new infrastructure is expected to increase Quantum’s camera production capacity by roughly 500% over its current level”, says Robert McDaniel, President and CEO of SCD.USA Infrared, LLC.
03 Oct 18. UK Wedgetail procurement to benefit Australian industry. The UK has confirmed that it was in discussion with Boeing and the Royal Australian Air Force about the potential for the E-7 Wedgetail Airborne Early Warning and Control (AEW&C) aircraft to replace its current E-3 Sentry fleet.
Minister for Defence Christopher Pyne and Minister for Defence Industry Steve Ciobo welcomed the announcement and said it would further deepen Australia’s relationship with the UK and was an endorsement of a crucial part of Australia’s air combat capability.
“The Wedgetail is a great Australian success story, designed for the Royal Australian Air Force with investment by the Australian government and significant contribution by Australian industry, it is a highly advanced world-best aircraft,” Minister Pyne explained.
Australia’s experience in operating the Wedgetail presents a significant opportunity to work closely with the UK through co-operative development and industry collaboration.
Minister Ciobo said, “A UK procurement will add to the global fleet of Wedgetails, already including Australia, Turkey and South Korea, which can be supported and sustained by Australian industry and create hundreds of Australian jobs. Australian industry, including the more than 200 Australian companies that have contributed to our own Wedgetail acquisition and sustainment, stands to benefit from what could become one of Australia’s most significant defence exports.”
This announcement follows the third Australia-United Kingdom Defence Industry Dialogue (AUKDID), held in London in July, with Minister Pyne explaining, “During the dialogue I took the opportunity to further promote Australia’s world-class Wedgetail capability to the United Kingdom’s Secretary of State for Defence and the then Minister for Defence Procurement.”
Defence Secretary Gavin Williamson, said “Our future with Australia will already see us operate the same maritime patrol aircraft, world-class Type 26 warships and supersonic F-35 jets. Wedgetail may join that formidable armoury and help us work together to take on the global threats that we both face.”
In a release, the UK Ministry of Defence (MOD) highlighted proven interoperability and capbility delivered by the E-7A Wedgetail, with the release stating: “It is a proven and reliable aircraft that has been in-Service with the Royal Australian Air Force for some time, with potential to considerably reduce the risk normally associated with acquiring a complex new platform of this nature. The aircraft is based on the Boeing 737 airliner family as is the P-8A Poseidon maritime patrol aircraft due to enter service in 2019.”
Additionally, the MOD stated, “With its proven interoperability, the Wedgetail could also link up with the RAF’s latest arrival, the F-35 Lightning, providing pilots with the latest intelligence and situational awareness demonstrating how a modernised next generation Air Force. With Australia also a partner in the F-35 programme, the RAF and the Royal Australian Air Force will have further opportunities to work together across platforms and with other allies such as the United States to share and collect data and conduct joint training missions, all leading to faster, more effective and more integrated combat forces.”
The Boeing 737 AEW&C is a state-of-the-art system providing powerful airborne surveillance, communications and battle management.
The 737 AEW&C system encompasses both the Boeing 737-700 aircraft platform and a variety of aircraft control and advanced radar systems. Consisting of components created by Boeing and Northrop Grumman, the 737 AEW&C represents the standard for future airborne early warning systems. The E-7A Wedgetail AEW&C functions include:
- A steerable beam, L-band, electronically scanned array that provides optimal performance in range, tracking and accuracy;
- Radar that can track airborne and maritime targets simultaneously;
- Assistance to the mission crew in directing the control of high-performance fighter aircraft while continuously scanning the operational area;
- A “top hat” portion that provides a practical solution for fore and aft coverage while maintaining the low drag profile of the dorsal array system – enabling the MESA system to be installed on the mid-size 737-700 platform without significant impact to aircraft performance;
- An integrated identification friend or foe (IFF) function that shares the primary radar arrays to reduce weight, improve reliability, and simplify target correlation; and
- Advanced open-system architecture with standards-based design for cost-effective integration and add-on flexibility.
This announcement comes a week after Boeing consolidated $1.5bn worth of contracts to support and enhance the capability delivered by the RAAF’s E-7A Wedgetails. Based at RAAF Base Williamtown, the six E-7A Wedgetails significantly improve the effectiveness of the ADF. They are capable of communicating with other aircraft and providing air control from the sky, and can cover 4 million square kilometres during a single 10-hour mission. (Source: Defence Connect)
03 Oct 18. Aircraft carrier HMS Queen Elizabeth has reached another milestone in her flight trials with the first night-time landings of F-35 Lightning jets. Britain’s biggest warship is currently conducting flight testing off the east coast of the United States and part of that is practicing landing in darkness. These tests were carried out with and without the aid of night-vision technology, with the pilots and aircraft handlers successfully guiding the fast fighter jets onto the flight deck.
Pilots initially flew in using only ambient light and the lights on the carrier’s deck before later conducting landings using the night-vision capability in their helmets.
Commander James Blackmore is the Commander Air in HMS Queen Elizabeth, who is referred to as simply ‘Wings’ by the ship’s company. He said: “The concept of night flying isn’t difficult for us. What we are looking at is what the new lights on board HMS Queen Elizabeth look like at night from the perspective of the F-35s.
“We’ve already done that with the rotary wing aircraft earlier this year, but now it’s crucial that we understand how suitable they are for the F-35s to operate at night from the carrier. First indications are that they are in good order for both the aided and unaided perspectives.”
The stealth F-35 jets flew from HMS Queen Elizabeth for the first time last week. Royal Navy Commander Nathan Gray and RAF Squadron Leader Andy Edgell were the first pilots to make history by landing their aircraft on the flight deck of the giant carrier.
Now the flying trials have swiftly moved on to the next phase, including the night-time flying which up until now has only been tested in simulators or on the ground.
Using the night-vision technology doesn’t always make landings easy as even the smallest light becomes ultra-bright when it is viewed through the specialist equipment.
The lights on a carrier’s deck can look fine to the naked eye but suddenly become very bright when night-vision is switched on. However, HMS Queen Elizabeth has been installed with specially-designed LED lightning on her flight deck, which solves the issue.
Even still, it is important for pilots to test their ability to land with and without night-vision assistance.
Andrew Maack, the Chief Test Engineer for the Integrated Test Force – the organisation responsible for analysing the flight trials – added: “In daytime there are cues that tell the pilot’s brain what the relative motion is between the airplane and the ship.
“At night, especially very dark night, all those cues go away and you become dependent on exactly what the lights are and what the sight of those lights looks like. It’s something you can’t translate in your mind ahead of time – you don’t know it until you see it.”
HMS Queen Elizabeth left her home port of Portsmouth in August, crossing the Atlantic to conduct the flying trials as well as training with the US Navy. More than 1,400 sailors, flight crew and Royal Marines have been working on board the carrier during her deployment.
The Royal Navy’s two new aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales, will project British military power across the globe for the next half a century.
Construction work continues at a pace on board HMS Prince of Wales, the second aircraft carrier in the class, which nears completion at the Rosyth shipbuilding yard.
They will be used to provide humanitarian assistance and disaster relief, strengthen defence relationships with our nation’s allies, and support British armed forces deployed around the world.
In recent operations, US aircraft carriers including the USS George HW Bush and USS Harry S Truman have played a central role in the Gulf and Mediterranean, conducting strikes against Daesh in Iraq and Syria.
HMS Queen Elizabeth is on track to deploy on global operations from 2021. Meanwhile, the UK has now taken delivery of 16 out of a planned 138 F-35 jets as part of its world-leading fleet of military aircraft for use by the Royal Navy and Royal Air Force.
03 Oct 18. CONTROP USA Inc. – a company specializing in the field of electro-optics (EO) and InfraRed (IR) defense and homeland security solutions – launches the MEOS-LRS, the latest member of its family of land-based automatic detection, recognition and identification surveillance systems with SWIR capabilities, at AUSA 2018. The MEOS-LRS provides long-range border / coastal surveillance and force protection where needed most. The SWIR capabilities enable vision and observation in difficult terrain and environmental conditions, including fog, smog, dust, and at twilight times. In addition to the automatic detection, recognition and identification surveillance functions, the panoramic observation capabilities of the MEOS-LRS enables quick decision-making regarding key focus areas – which are critical for surveillance and force protection. The system enables execution of exact target coordinates based on the combined GPS system. The compact, portable system may be carried on a soldier’s back and is quickly and easily deployed.
The MEOS-LRS multi-spectral system provides maximum sensor range performance by using highly sensitive sensors and unique video enhancement algorithms. Features include a compact EO/IR gyro-stabilized day-and-night system, 360⁰ observational coverage, panoramic map view, scanning capability, and automatic detection. The system may be configured for medium-to-long ranges with Thermal Imaging detection range of 25km for NATO target. A 720mm Thermal Imaging Camera, 660 mm high resolution Day Camera, a Laser Pointer, and an optional Laser Range Finder (LRF) are included.
According to Mr. Guy Oren, CONTROP USA’s VP Business Operations North America, “The MEOS-LRS system was specially developed to provide long-range observation and surveillance capabilities for border and coastal surveillance as well as force protection. The payload has high electro-mechanical stability with both internal and external stabilization and line-of-sight stabilization, which significantly improves the image quality as well as the panoramic view. Though new, the MEOS-LRS is already in daily operational use with additional orders expected, and is being evaluated by several other customers prior to anticipated purchases of this very cost effective system.”
02 Oct 18. US Army continues push for integrated sensors and shooters with latest IBCS contract. The U.S. Army awarded Northrop Grumman a $298m contract modification to continue development and enhancement of the company’s Integrated Air and Missile Defense Battle Command System, or IBCS, Sept. 28.
These funds will pay for upgrades to IBCS engagement operations centers and integrated fire control network relay to boost performance and reliability, and make the systems easier to maintain, according to a Northrop statement. The company will also deliver IBCS software version 4.5 to integrate Patriot system updates.
“IBCS creates a paradigm shift for IAMD, and we have proven many transformational capabilities that will be game-changers on the battlefield. IBCS maximizes the combat potential of sensors and weapons while allowing future modernization at lower overall lifecycle costs,” said Dan Verwiel, Northrop Grumman vice president and general manager, missile defense and protective systems. “From integrating weapons developed decades ago with capabilities still in development, to rapidly adding protection against emerging threats and enabling seamless multi-domain operations, through logistics, training and lifecycle support, IBCS is solving some of the most difficult defense challenges confronting our nation and allies today. ”
The brain behind the Army’s future air and missile defense command-and-control system, IBCS is considered an essential component of future multidomain operations. The system has performed well in a series of flight and operational tests, but has experienced substantial delays as the Army’s envisioned mission for the system has grown.
Initially, IBCS was meant to link sensors, launchers and shooters under one air and missile defense architecture, but the Army now plans to use IBCS to integrate other vital air and missile defense systems on the battlefield, including the Army’s Indirect Fire Protection Capability, which is designed to defend against rockets, mortars and artillery as well as cruise missiles and unmanned aircraft systems. After reviewing fiscal 2017 budget documents, Defense News first reported the initial operational capability for the program was delayed by four years and would need an additional half-billion dollars across a five-year span beyond previous budget requests.
ICBS will also be used to link together two of the Army’s most critical air and missile defense capabilities, the Terminal High Altitude Area Defense system, or THAAD, and the Patriot short- to medium-range air and missile defense system. Getting these systems to effortlessly communicate is important to increase operational capability and paint a better picture of incoming threats.
But IBCS won’t only benefit the Army. The system has been tested in live joint exercises with the Navy, Marine Corps and Air Force, leveraging the Link 16 tactical data link that is employed on the Navy’s Aegis BMD guided-missile destroyers and Army’s AMD systems. During a test in April, IBCS controlled multiple sensors and interceptors from disparate air defense systems to track and defeat a ballistic missile target and a cruise missile target.

02 Oct 18. UK in exclusive talks with Boeing to replace Awacs aircraft. Move likely to spark backlash from defence establishment over lack of competitive process. Britain has begun exclusive talks with Boeing, the US aerospace group, about a multibillion pound contract to replace its fleet of ageing surveillance aircraft for the Royal Air Force. The decision to move ahead with one potential supplier, coming ahead of a Nato conference this week, is likely to spark a backlash from parts of the defence establishment as it has been done without a competitive process. The RAF has been keen to secure a replacement for its fleet of six Sentry E-3D airborne warning and control system aircraft (Awacs) which have been in operation since 1992. Gavin Williamson, the defence secretary, confirmed that the Ministry of Defence was in talks with Boeing about the potential of its E-7 Wedgetail radar aircraft to replace the Sentry fleet. Boeing’s E-7 is based on a standard Boeing 737-700 airliner modified to carry an advanced, electronically scanned radar and 10 state-of-the-art mission crew consoles which can track airborne and maritime targets simultaneously. The project could cost the MoD around £5bn over its expected 20-year operational lifespan, for which Britain will receive five or six E-7 aircraft. One consideration in the decision, according to sources close to the talks, was that Australia’s air force had already procured the E-7. A UK purchase would deepen the two nations’ defence co-operation. Both already operate the same maritime patrol aircraft, Type 26 warships and F-35 fighter jets. Australia earlier this year selected the British Type 26 design for its future frigate. Recommended UK defence spending Britain’s ‘withered’ forces not fit to repel all-out attack Mr Williamson said the Wedgetail “is the standout performer in our pursuit of a new battlespace surveillance aircraft, and has already proved itself in Iraq and Syria.” “Our future with Australia will already see us operate the same maritime patrol aircraft, world-class Type 26 warships and supersonic F-35 jets,” he said in a statement. “Wedgetail may join that formidable armoury and help us work together to take on the global threats that we both face.” The MoD is expected to stress that further discussions with Boeing will take place before a final investment decision is made to ensure the aircraft represents value for money. It seems unsatisfactory that these deals are done on the basis of excluding viable alternatives from even being considered. There ought to be a fair competition Julian Lewis The department is, however, expected to face criticism over its decision to move ahead without a competitive tendering process. Analysts have said that Airbus, the European aircraft group which has invested heavily in the UK, could offer an alternative based on its A330 jetliner. But Boeing’s offering is currently the only such aircraft already in service, including with Turkey, Korea and the US in addition to Australia. Julian Lewis, the Conservative MP who chairs the Commons defence committee and who had previously raised concerns about the lack of an open competitive process, said he was aware of one alternative aircraft system which the UK could have looked at before opting for the Wedgetail. “It may be that Wedgetail would have won,” said Mr Lewis. “But it seems unsatisfactory that these deals are done on the basis of excluding viable alternatives from even being considered. There ought to be a fair competition.” “If you go for sole source, where is your negotiation position?” asked Francis Tusa, editor of Defence Analysis. “There is no rush to make a decision,” he added. News of the talks comes as negotiations between Mr Williamson and Philip Hammond, the chancellor, enter a critical phase ahead of the Budget on October 29. Mr Williamson and his defence chiefs are arguing for more money to help plug a potential £20bn shortfall over the next decade in the MoD’s new equipment budget. If selected, Boeing is expected to confirm that the conversion work of the 737s would be undertaken at Marshall Aerospace and Defence Group, an independent aerospace company in Cambridge, and support hundreds of jobs at the site. The US company employs around 2,300 people in the UK and spent $2.3bn in the UK supply chain in 2017. Boeing declined to comment. (Source: FT.com)
01 Oct 18. UAVOS Fixed-Wing Sitaria Completed Flight Tests. UAVOS Inc. has completed a series of test flights of a new Sitaria fixed – wing UAV. The new UAV is designed for patrol and observation missions, for aerial photography of terrain area with a radius of up to 120 km. Among other tasks, the unmanned aircraft is purposely designed to work with the LIDAR airborne laser scanning equipment as payload.
UAV Sitaria has a wide range of speeds (stall speed 65 km/h, maximum speed 150km/h), which allows the aircraft to carry out missions at minimum flight speeds close to 70 km/h. For example, taking into account a tailwind of 6m/s, the minimum operational speed of the aircraft will be about 90km/h. To fulfill a mission using LIDAR it is important to maintain a certain speed of the aircraft relative to the ground. When the UAV performs monitoring while moving against the wind, it shall keep high air speed, and moving upwind – lower speed.
Vadim Tarasov, UAVOS investor and board member comments: “During monitoring missions, a wide range of speeds allows Sitaria fixed – wing drone to quickly reach the object and return back at the optimal speed. Takeoff and landing is carried out at low speeds, which makes it possible to use short runways. All these features directly affect safety, and also optimize operating costs.”
The weight of Sitaria is 35 kg, the wingspan is 5.2m, the length of the fuselage is 2.8m. Flight time with a payload of 4kg is 3 hours, operating altitude is up to 6000 m. The range of the video transmission can be up to 60km; the backup Iridium command line is unlimited in range. The EW countermeasure function provides an opportunity to carry out research under jamming of satellite radio navigation signals and the command line channel. Sitaria fixed-wing drone is a part of the unmanned aerial system Sitaria, which includes a ground control system. The UAV is equipped with an electric motor, which is less noisy and more reliable; low vibration level does not affect the stable work of the payload. Sitaria unmanned airplane has a unique aerodynamic design allowing to quickly adjust the position of the wing relative to the fuselage when the weight of the payload changes. The minimum tail weight has a positive effect on the control and stability of the aircraft.
“Technical solutions, implemented in Sitaria, provide the high level of fail-safety, reliability and security that is required for operation in diverse areas of commercial applications of the UAV,” says Vadim Tarasov. (Source: UAS VISION)
01 Oct 18. VTT’s NanoSat hyperspectral camera delivers high quality spectral data after enduring one year of space wheather and a solar storm. VTT’s hyperspectral imager continues to observe the earth on board the Aalto-1 nanosatellite. For hyperspectral imagers it is unique to reach such a small size and weight, and also to prove a capability to survive in harsh space conditions on-board a small satellite. It has even survived a grade X solar storm while still continuing to supply high-quality data.
The hyperspectral camera on Aalto-1 operates in a wavelength range of 500–900 nanometres and is half a cubesat unit (0.5U) in size, or 5 cm x 10 cm x 10 cm. While the camera is up in space, it has been possible to program the operation wavelengths from Earth, which makes it easy to scale the same camera hardware to enable different applications.
The spectral image was taken over central Africa in August, and it shows and the Tshuapa river near Mbandaka. The “red edge” of vegetation is clearly visible: the reflectance of the forest rapidly increases around 700nm.
“It is much more difficult to distinguish these features from the regular camera image of the same target. Hyperspectral imaging can help distinguish information which is not visible from regular images”, comments Senior Scientist Antti Näsilä on the recent land-target images received from Aalto-1.
“The severe solar storm in fall 2017 was the ultimate test for the ability of our hyperspectral camera technology to withstand extreme space conditions”, says Näsilä.
Since small satellites are cost-efficient to launch, it is possible to form constellations of multiple smallsat instruments, which can provide global observation data with better real-time coverage than traditional satellites. This makes it possible to use space technology in the creation of novel service concepts on Earth based on data and AI, expanding to completely new markets such as insurance and agriculture.
VTT’s next new instrument waiting to be launched to space soon is the world’s first CubeSat near- and short-wave infrared (NIR/SWIR) hyperspectral imager.
“Data obtained from this new spectral range increases the application potential significantly, because the infrared range beyond the visible wavelengths contains much more information about the chemistry and composition of measurement targets. This type of data is useful for example in creating novel service concepts for agriculture or in analysing composition of asteroids”, says Research Team Leader Anna Rissanen. VTT’s hyperspectral imaging technologies have been developed for a wide variety of wavelengths as well as applications. ”We are constantly looking for partners both from industry and academia in order to create societal impact”, says Rissanen.
28 Sep 18. Northrop Grumman demos unmanned capabilities at ANTX. An MQ-8C Fire Scout surrogate aircraft has demonstrated its ability to autonomously deliver underwater sensors for the first time, Northrop Grumman announced on 19 September. During the demonstration, which was conducted in late August as part of the US Navy’s (USN’s) Advanced Naval Technology Exercise (ANTX) in Newport, Rhode Island, the P10 Bell 407 helicopter – which the MQ-8C unmanned aerial vehicle (UAV) is derived from – delivered multiple sonobuoys into the exercise area to support mine warfare operations and maritime situation awareness. Mine warfare operations were also supported by Northrop Grumman’s deployment of its Micro Synthetic Aperture Sonar (μSAS) technology, integrated on board an autonomous underwater vehicle (AUV) and launched from a navy work vessel participating in the exercise.
