CANADA AVIATION AND SPACE MUSEUM AIRCRAFT SAGEM CU-161 SPERWER CANADIAN ARMED FORCES SERIAL CU161001 INTRODUCTION Designed by a French company, SAGEM,1 the Sperwer (Dutch for Sparrow Hawk) Unmanned Aerial Vehicle (UAV) system was comprised of aerial vehicles, a ground control station (GCS), a transportable hydraulic catapult and a ground data terminal (GDT) housed in a communications shelter carried on high mobility vehicles. The entire system could be transported in five C-130 Hercules aircraft and could operate from unprepared sites using a catapult launch and a combined parachute and airbag recovery system. The overall system supported simultaneous control of two aerial vehicles, from a single GCS. Furthermore, several GCSs could control multiple missions, and could hand-over UAVs between each other. The ground station was equipped with advanced mission planning tools, including 3-dimension terrain modeling and flight path presentation on a geographical data system, image processing, interpretation and connection to command and control networks. The Sperwer platform was primarily designed to carry a Forward Looking Infrared (FLIR) payload, providing high resolution day and night imagery and target geo-location with an accuracy of 20 meters (65 ft 6 in). In Canada, the Sperwer system was procured as an Urgent Operational Requirement (UOR) in support of ongoing Canadian Army operations in Afghanistan. In August of 2003, the Canadian Forces (CF) provided a battalion group and and brigade headquarters in support of a 12-month mission in Afghanistan (known as Op ATHENA). Their mission was to provide security and stability in the Kabul region and in order to provide “real time” situational awareness, the Army urgently acquired the Sperwer as a tactical UAV (TUAV) system. Designated, while in Canadian use, as the CU-161 Sperwer, the system was used in Afghanistan from October 2003 until April 2009. It was then declared as A Canadian Forces CU-161 Sperwer is catapulted from “surplus” and, on 11 August 2009, most of the remaining its launcher on a mission - (CF Photo) Canadian Forces (CF) Sperwer UAV air vehicles / assets that were still in flyable condition were sold to the French Government. The Sperwer was the first UAV operated by the CF in combat and it paved the way for the use of future UAV systems, including the CU-170 Heron system which was also employed in Afghanistan.

Its lineage is rather complex. While the SAGEM Crécerelle (Kestrel) was its immediate, direct ancestor, the shorter-range Sperwer UAV was, in fact, derived from the Meggit Defence Systems Banshee, a British target drone. Meggit also marketed a very similar design to the Crécerelle known as the Spectre. All of these earlier designs helped influence the delta-winged platform of the Sperwer tactical UAV. The Crécerelle was intended as a low- risk battlefield reconnaissance platform. The Above - The Sperwer design owed much to the British-designed French 7th Artillery Regiment took the Crécerelle Meggitt Banshee, as seen here on its launcher. - (Finish Armed Forces image) to Macedonia, where they operated alongside Bundeswehr Luna Below - the SAGEM Crécerelle was the immediate predecessor the CL-289 and German to the Sperwer and the design similarities are apparent. - UAVs. While these operational trials were (SAGEM image) successful, they also showed the need for greater speed and range. The Sperwer design provided these requisite improvements and consequently replaced the Crécerelle in French service. After entering Dutch service, the Sperwer was not only been adopted by France but also by Sweden, Denmark, Canada, and Greece. The Sperwer was fairly conventional for a modern tactical UAV. Its airframe design was constrained by the need to position turret- mounted sensors close to the UAV's nose. As a result, the Sperwer's powerplant was positioned in its tail, driving a 4-bladed, pusher-propeller. The Sperwer's small delta wings, angled twin tails, and simple rectangular fuselage-section all served to lower the vehicle's radar return signature. The Sperwer airframe was also designed to be compact in order to be as portable as possible. The Sperwer possessed a 4.2 m (13 ft 9 in) span delta wing. Engine radiators were mounted on either side of the fuselage beneath each vertical The SAGEM Sperwer featured twin tails as opposed the tail. The use of liquid-cooling was somewhat singular fin on previous designs. - (SAGEM Image) unusual for a small 2-stroke UAV powerplant but it served to reduce engine noise, making the Sperwer harder to spot. The two-cylinder engine generated 48 4 / 35 kW (65 hp) at 6500 rpm, an impressive output considering its tiny 581 cc (35 cu in) displacement. Still, the surplus power of a Sperwer was marginal, severely restricting its “hot-and-high” performance. SAGEM consequently made improvements to subsequent variants. The Sperwer's pneumatic rail-launcher was carried by a 10-tonne (22,000 lb) truck. The Sperwer sat in a cradle, which was propelled along an elevated rail to gain flying speed. The post-mission recovery was via a 117 m2 (1,259 ft2) parachute, which deployed from a hatch in the upper fuselage. The landing was further cushioned by airbags under each wing, as well as The Sperwer’s engine. - underneath the fuselage. (Bombardier Image) The forward-fuselage airbag protected the Sperwer’s video sensor. This camera was mounted in a prominent ball-turret beneath the nose. Ground-based operators used a joystick to aim this video camera, generating live images. Alternatively, the camera could be locked onto a target while the Sperwer manoeuvered, or the Sperwer could be instructed to follow the camera's line-of-sight. A fixed, video camera in the Sperwer's nose also gave operators a forward-looking, wide- angle view of the flightpath. SAGEM went on to develop a longer endurance model of original design (now called the Sperwer-B) distinguished by an This view of the front of the Sperwer clearly illustrates the ball turret and the forward-looking camera port. - (CF Photo) extended 6.2 m (20 ft 4 in) span wing. The Sperwer-B also has canard control surfaces which, like the extended wing, are derived from the turbojet -powered Sperwer HV (Haute Vitesse) variant. Canadian Forces UAV Use 3 Prior to 2000, the CF had only sporadically experimented with various Unmanned Aerial Systems (UAS) during specific trials and exercises. By the turn of the century, however, UAS use had proliferated in other countries and the CF also embarked on rapid series of intensive trials and exercises. Operation (Op) ROBUST RAM was the first chance that DND had to experiment with some of these newer systems. This exercise took place in April 2002 at Canadian Forces Base (CFB) Suffield, Alberta and involved the leasing and trial of three different systems: the Pointer (produced by AeroVironment), which was a mini-UAS, the CL-327 Guardian (produced by Bombardier), also The AeroVironment POINTER was a small, hand- launched UAV. - (CF Photo) better known as the “Peanut” UAS, and the I-Gnat 5 / 35 (produced by General Atomics), which was a medium- altitude, long-endurance UAS. Op ROBUST RAM therefore trialled a layered system of UAVs in an integrated fashion. During the exercise, the Pointer conducted 39 missions (totaling 15.9 flight hours). This platform operated at less than 152 m (500 ft) above ground level, and had an operational radius of less than 10 km (6.2 mi). By comparison, the CL-327 Guardian completed seven missions (totaling 15.3 flight hours), and flew at altitudes between 1,500 - 3,048 m (5,000– 10,000 ft) above sea level (ASL). And finally, the I-Gnat also flew seven missions (totaling 29.4 flight hours), at The Bombardier CL-327 GUARDIAN design was a altitudes up to a maximum of 4,572 m (15,000 ft) ASL. unique helicopter - like UAV design often referred to as the “Peanut” .- (US Navy Photo) Then, in June 2002, during the G-8 Summit Conference in Kananaskis, the CF was tasked to assist with security in an exercise known as Op GRIZZLY. As part of this operation, the CF again leased the I-Gnat UAV system, in order to provide an “overwatch capability”. The aircraft was limited to a 56 x 65 km (30 x 35 nautical mile) operating box around Kananaskis, and the CF established a Joint Airspace Coordination Centre to integrate the I-Gnat in with other airspace users. The Op GRIZZLY, was immediately followed by yet another exercise known as the Pacific Litoral ISR Exercise (or PLIX). The PLIX exercise took place off Vancouver Island in July 2003. Flying from the airport in The General Atomics IGNAT was very similar in design to the much more famous Predator drone produced by Tofino, another leased medium-altitude, long-endurance the same company.
