v1.4.1 / chapter 10 of 19 / 01 mar 08 / greg goebel / public domain
* Battlefield UAVs are now in use or development all over the world. This chapter discusses battlefield UAV developments in Israel, Canada, and France.
* The Israelis were the prime movers in establishing the battlefield UAV as a standard military weapon. After the Yom Kippur War in the Middle East in 1973, when the Israelis suffered substantial air losses from Soviet built SAMs fired by Arab forces, the Israeli military searched for new technology to ensure they would not have the same problems in the future. This led them to cross paths with Alvin Ellis, who had been born and raised in the US and worked for Ryan on the Firebee and the Lightning Bugs. He emigrated to Israel in 1967 to join Israel Aircraft Industries and work on the Kfir fighter, a derivative of the French Dassault Mirage III/5 fighter but fitted with an American GE J79 engine.
The history of Ellis and the battlefield UAV tends to recall that of Reginald Denny and the target drone. Ellis liked to tinker with RC models, and after the Yom Kippur War he decided that a small drone with a TV camera might be an answer to some of Israeli's battlefield needs. He joined up with an IAI colleague named Yehuda Manor and the two put together a prototype in Manor's garage. They flew the prototype for a short time, but it crashed when one of its two engines failed. Ellis still felt the idea was good and pitched it to IAI management, but was turned down. Undiscouraged, Ellis took the idea to Tadiran, the Israeli electronics conglomerate, and the company funded a second prototype.
The prototype flew in 1973. It was just a large hobbyist's RC airplane, similar in configuration to Reginald Denny's early Radioplane drones. The new prototype was successful and led to a demonstrator named the "Owl" that was fitted with a cheap TV camera. It was demonstrated to Tadiran and military brass in early 1974. Tadiran management was sold on the idea and gave Ellis a contract to develop an operational system named "Mastiff". The Mastiff had a different configuration from the early prototypes, featuring the pusher-propeller twin-boom configuration that would become common for combat surveillance UAVs. The Mastiff was introduced in 1975, but nobody seemed interested.
Ellis did a stint back in the US in the late 1970s working on drone autopilots for American companies, while the Mastiff gathered dust. Only two were sold by 1979. The lack of activity was deceptive. The Israeli military was becoming increasingly interested in battlefield UAVs, and in response IAI management finally decided the company was interested in the concept as well. Tadiran and IAI found themselves in bitter competition for military battlefield UAV contracts. The Israeli military began to buy more Mastiffs, while IAI came up with a competitor with the appropriate name of "Scout" and sold it to the military as well. The Scout, also known as "Zahavan (Oriole)", had a similar configuration to the Mastiff, with a pusher propeller and a twin-boom tail.
In June 1982, the Israelis began major military operations in Lebanon, where they were confronted by Syrian SAMs, which were heavily sited in Lebanon's Bekaa Valley. All 28 SAM sites in the Bekaa were destroyed, however, partly through the use of Sampson decoys to get them to reveal their presence, and partly through reconnaissance information obtained by the Mastiff and Scout UAVs.
* Israeli battlefield UAVs had proven a great success, and soon came to the attention of the US military, particularly after the American intervention in Lebanon in 1983. This led to the US Navy's request for a battlefield UAV in 1984, and Tadiran and IAI decided, or were told to, join forces to submit a proposal for the American requirement. The result was an IAI division named "Mazlat", now "Malat".
The US military is reluctant to buy from foreign sources, so foreign companies always team up with an American company to push a sale. AAI had already worked with Tadiran to sell the Mastiff in the US, so AAI was a logical choice, and Mazlat and AAI developed the Pioneer, which won the competition. Since then, Malat has developed more advanced battlefield UAVs, and has collaborated on battlefield UAV developments with partners such as AAI.
* After consolidating production of the Mastiff and Scout, the Malat company continued to sell them in slightly refined versions for over a decade. Both aircraft have fixed landing gear and are generally operated from runways, performing short landings using an arresting-wire hook, though they may be launched using a hydraulic catapult off the back of a truck, and recovered by a net. They both carry imaging sensors in a turret underneath the fuselage.

The Mastiff and Scout remained in service with the Israeli Army until the
early 1990s, when they were replaced by the Malat "Searcher", also known as
the "Meyromit (High Flier)". The Searcher looks almost identical to the
Scout and Pioneer, but is scaled up, and in fact is well over twice the size
of the Scout. The Searcher is powered by a 35 kW (47 HP) piston engine. It
not only features updated avionics and sensor systems as well as greater
endurance, but increased redundancy to improve survivability.

The Israelis have considered means of silencing the UAVs' engines, whose
chain-saw sound often tips off adversaries to the fact that they are being
observed.
* While Malat has been moving towards bigger and bigger battlefield UAVs, the
company has also been exploring the lower end of the range, with an
interesting aircraft known as the "I-View". Like its larger relatives, the
I-View has fixed landing gear and a pusher propeller, with an 18.6 kW (25 HP)
piston engine. It has a unique configuration, with a tail-boom mounted on
the top rear of the fuselage that ends in an "inverted vee" tail. The I-View
is also being promoted in civilian markets for forest-fire warning, and in
this form is appropriately known as the "FireBird".

* The MBD missile division of IAI sells another UAV, the "Harpy", which is an
antiradar loitering attack drone. It patrols over a battlefield, waiting for
somebody to turn on a radar, and then dives into it, destroying it with a
blast-fragmentation warhead. The Harpy is in service with the Israeli
Defense Forces, as well as Turkey, India, China, Taiwan, and the Republic of
Korea.
The Harpy is a delta-winged machine with finlets on the wingtips. It weighs 135 kilograms (300 pounds), and is 2.7 meters (8 feet 10 inches) long with a span of 2.1 meters (6 feet 10 inches). It is powered by a UAV Engines Limited (UEL) AR731 rotary engine, with 28 kW (37 HP), driving a pusher propeller. Maximum speed is roughly 185 KPH (115 MPH / 100 knots), and endurance is about six hours. Although the Harpy is clearly different in appearance to the Boeing BRAVE 200, the two UAVs are conceptually similar in many ways, and the Harpy has a similar launch scheme. 18 Harpies are carried by a truck, with each UAV in its own sealed container. Three trucks make up a battery, which also includes a mission control center.
A Harpy can be fueled, programmed, and tested inside its container, which is then opened for launch by RATO booster. After launch, the UAV makes its way to its patrol area, following navigational waypoints provided by the command center, and then flies circuits, waiting for a radar to turn on. On finding a radar, it dives into it almost vertically, detonating before impact to ensure maximum damage to the radar site. If the radar is turned off and the Harpy loses target lock, the UAV returns to its patrol. If no radar is spotted by the time the Harpy is running low on fuel, the UAV will self-destruct.
* Another Israeli firm, Silver Arrow, a collaboration between Elbit and Federmann Enterprises, focuses on selling large UAVs, but also sells two small battlefield UAVs, including the "Sniper" and the "Micro-V".
The Sniper's configuration resembles that of a conventional private aircraft
with fixed tricycle landing gear, driven by a nose-mounted propeller and a
28.5 kW (38 horsepower) piston engine. Its only unusual feature is an
upright vee tail.

The Micro-V is a neat little mini-UAV, powered by twin 3 kW (4 HP) piston
engines, one in a nacelle on each wing driving a pusher propeller. It has no
landing gear. The Micro-V appears to be too small to carry a full sensor
turret, carrying a miniaturized imager in a transparent section built into
the middle of its fuselage.

In 2002, Silver Arrow introduced a new "high-end" tactical UAV, the "Hermes 180". It is a piston-powered machine with a pusher prop. Instead of having a twin-boom tail as do many other UAVs in its class, the Hermes 180 has single boom perched on top of the fuselage on struts, ending in a twin-fin tail. Sensor payloads are carried in a turret under the middle of the fuselage. The Hermes 180 can operate at up to 4,575 meters (15,000 feet) in line of sight to its ground station, and has an endurance of more than 10 hours.
* The Canadians have proven enthusiastic about battlefield UAVs, and in fact have been in the business since the early 1960s. In 1961, Canadair LTD, now part of the Canadian Bombardier group, began development of a battlefield UAV that was eventually designated "CL-89" or "AN/USD-501". The requirements specified a rugged UAV that would be easy to use under battlefield conditions, highly survivable in a combat environment, and provide intelligence day or night in any weather in a timely fashion. Initially, the project was funded by both the Canadian and British governments, but in 1965 West Germany joined in the effort as well. Flight testing began in 1964 with cooperation with the US at the US Army proving grounds in Yuma, Arizona. Initial orders and production for the CL-89 did not begin until the early 1970s. Several hundred were ordered.
The CL-89 looked more like a missile than a UAV, with a torpedo-like fuselage, rectangular cruciform wings, and small triangular cruciform control fins on the nose. It was powered by a Williams Research WR2-6 turbojet engine with 559 N (57 kgp / 125 lbf) thrust fed by twin inlets on each side of the fuselage between the wings.
The CL-89 was launched on a rail from a truck using a RATO booster attached
to the vehicle's tail, with the booster providing 20.2 kN (2,065 kgp / 4,550
lbf) thrust for 2.5 seconds. The CL-89 then continued on a preprogrammed
course, performing its observations and returning to the recovery site,
assisted by a homing beacon. Once at the recovery site, the UAV deployed a
drogue chute to slow down, and then popped out a parachute and two airbags
for a soft landing. Two of the wings folded back when the airbags deployed
to ensure that they weren't damaged on touchdown.

_____________________ _________________ _______________________
The CL-89 had a modular design, with plug-in packs for the two airbags, a
dispenser for illumination flares, the parachute system, and the sensor
system. Sensor systems included a Zeiss optical camera pack and a
Hawker-Siddeley infrared camera pack. The CL-89 apparently saw limited
service with Canadian, British, and German forces, with the British Army
using it in combat during the Gulf War in 1991.
* The CL-89 led to an improved version, the "CL-289" or "AN/USD-502",
developed as a collaborative program between Canada, France, and West
Germany. The UAV was built by Canadair. It was integrated for German
operations by Dornier, and for French operations by Aerospatiale. It went
into service with West German forces in 1990 and with French forces in 1992.
A few CL-289s that were excess to German needs were later sold to the French.
The CL-289 is very similar to the CL-89 but slightly larger, with the most
visible difference being that the wings of the CL-289 have a leading-edge
sweep and are not rectangular like those of the CL-89.

_____________________ _________________ _______________________
The CL-289 can be fitted with a Zeiss film camera pack, or a French SAT
Corsaire infrared imager that can relay real-time imagery to a ground control
station. An "AOLOS-289" upgrade was offered from 2003, with the Germans and
French refitting their CL-289s up to this standard. AOLOS-289 UAVs are
easier to maintain, have GPS navigation capabilities, and a modernized
mission planning and control system. Several European companies have
collaborated to develop a miniature SAR all-weather sensor pack for the
CL-289, but it does not appear to have been fielded yet. Digital optical
imaging packs are being considered.
During the 1990s, the German Army deployed CL-289s to support operations in the former Yugoslavia, seeing combat action during the Kosovo air campaign in the spring of 1999. During this operation, the Germans fielded 18 CL-289s from a launch site in Macedonia, with three being lost. The Germans hope to keep their CL-289s in service until at least 2013.
The CL-289s were flown at altitudes from 200 to 1,000 meters (660 to 3,300 feet), over preprogrammed routes up to 400 kilometers (250 miles) long, with the missions lasting 30 to 40 minutes. The CL-289s could provide real-time video back to the control stations as long as they remained in line of sight, and then they took images on conventional or infrared film. The French also operated their CL-289s over the former Yugoslavia and in the intervention in Afghanistan in 2001:2002.
In the summer of 2002, the Italian Army decided to buy 20 CL-289s, along with a mission control center and two launchers, to support the Italian military commitment to the new European Union Rapid Reaction Force. The CL-289s were bought as an interim solution until a more modern UAV could be obtained.
* The Canadians also developed a helicopter-type battlefield UAV, the Canadair "CL-227". The CL-227 features a body resembling a peanut in shell stood on end, with coaxial rotors around the midbody and a sensor turret on the bottom. Unsurprisingly, it is nicknamed the "Peanut". It has a ring-shaped landing skid around its base, and can be operated as a free-flying or tethered drone.
The initial prototype of the CL-227 was powered by a Wankel rotary engine and first flew in 1978. The second prototype was powered by a Williams Research WR-34-15 turboshaft engine with 24 kW (32 SHP), and first flew in 1981. After demonstration to various military services, Canadair began full-scale development of the Peanut in 1984, with operational introduction at the end of the decade.
The CL-227 was followed by a refined design, the Bombardier "CL-327", which
was introduced in 1996. It is similar to the Peanut, but looks like two
mushrooms joined stem-to-stem. It is powered by a Williams Research
WTS-117-5 turboshaft engine with 94 kW (125 SHP). It has GPS-INS location
capability and a programmable waypoint autopilot system.

_____________________ _________________ _______________________
Two CL-327s can be carried and operated by a single Hummer light truck or
similar vehicle. The CL-327 was evaluated by the US Navy for the VT-UAV
competition, but lost the competition. Bombardier is now promoting a still
further improved version of the UAV, the "CL-427 Puma", with the same
configuration but with the mushroom-shaped enclosures replaced by
"weathervane" shaped fairings.
* The French operate the CL-289 and the Israeli Hunter, as well as a number
of French-designed UAVs. One of the earliest was the Altec "Mini-Avion de
Reconnaissance Telepilote (MART)" series, with the MART II serving with
French forces in the Gulf War. Details of the MART II are difficult to find,
but pictures of it show it to be a relatively small tactical UAV, with a
simple conventional configuration like that of a large RC model. It is
catapult-launched, carries an imaging system, and appears to be recovered by
parachute.

Altec is now selling an improved version of the MART II, the "S-MART". It is
slightly heavier, has 7 hours endurance, and can carry ELINT and jamming
payloads.
* The French Sagem firm also produced a medium-sized UAV, derived from the popular Meggitt Banshee target, known as the "Crecerelle" ("Kestrel" or "Sparrowhawk"). Its configuration is much like that of the Banshee, with a pusher prop, a clipped delta wing, and a single tailfin, though its fuselage is more cylindrical. It is powered by a 20 kW (26 HP) rotary engine and has no landing gear, being recovered by parachute and airbags. The Crecerelle saw action with French forces during the Kosovo campaign in 1999. Meggitt sells much the same machine as the "Spectre".

France, and Greece. The Swedes call it the "Ugglan (Owl)". Like the
Crecerelle, it uses a pusher propeller and has clipped delta wings, but it is
larger, has twin tailfins, a boxier fuselage, and an EO sensor turret under
the nose. It is powered by a 29.5 kW (65 HP) two-stroke Rotax engine.

_____________________ _________________ _______________________
Sagem has sold well over a hundred Crecerelles and Sperwers. Canada is the
latest customer for the Sperwer, obtaining a system of four low-end UAVs
during the summer of 2003 for use by Canadian forces in Afghanistan. The
Canadians expect to buy more and keep the type in service over the long term.
Sagem followed up the original Sperwer with the "Sperwer B", which is similar to the original variant but features longer endurance. The Canadians are interested in obtaining an additional batch of Sperwers or Sperwer Bs. Sagem has been working on integrating a miniaturized SAR and a satellite datalink into the Sperwer system. Sagem has also experimented with an armed Sperwer, displaying a machine carrying two Israeli Rafael Spike anti-armor missiles at the Paris Air Show in 2005.
* Matra BAE Dynamics developed a UAV named "Dragon", no relation to the BAI Dragon. The Dragon was roughly the same size as and similar to the Crecerelle, with the same pusher-prop delta configuration, except that instead of having a single tailfin mounted on the fuselage, the Dragon had a finlets on each wingtip. It was intended as a jamming platform. It seems to have dropped out of sight, possibly because the French Army acquired the Crecerelle for the jamming mission.
* CAC Systems of France, discussed earlier as a manufacturer of aerial targets, also produces a number of different battlefield UAVs, including the "Fox" series, the "K100", and the "Heliot" UAV helicopter, as well as the Aerovironment Pointer, built under license.
The Fox is a mini-UAV powered by a 16 kW (22 HP) piston engine. About a
thousand have been sold in a number of variants, with generally similar
appearance and specifications. Specifications for the electronic
warfare-variant, the "Fox-TX", are as follows:

when fitted with a warhead and a radar-homing seeker, anti-radar attack. The
Fox-TX can also carry two small underwing stores. Other Fox variants
include:
Unlike the Fox-TX, the Fox-AT1 has a skid to permit belly landings. It can carry four small underwing stores. Endurance is only an hour and a half. French forces have used the Fox-AT1 for tactical reconnaissance in the Balkans.
* The CAC Systemes K100 is a mini-UAV. The company sells a reconnaissance variant, the "K100/R", and an antiradar loitering attack variant, the "K100/A". The K100 is of conventional aircraft configuration, except for an upright vee tail and a pusher propeller. It has no landing gear.
