3. INTRODUCTION
Sperwer B (Sparrow Hawk B) is a long-
endurance tactical unmanned air vehicle
and a variant of the Sperwer A (formerly
called Sperwer).
Sperwer B can be used for long-endurance
missions such as battlefield surveillance, as a
communications relay or be armed for
combat missions.
5. DEVELOPMENT
A prototype interim design version first flew at the Mourmelon range
in 2001 and the first flight of the Sperwer B was in 2004.
Compared to the current Sperwer A, the B version has twice the
payload capacity, 100kg for Sperwer B and 50kg for Sperwer A, and
twice the endurance, 12 hours for Sperwer B compared to six hours
for Sperwer A.
A series of endurance test flights were successfully completed at
the Robonic Arctic test UAV flight centre in Kemijarvi in Finland
during 2006.
7. VEHICLE
The Sperwer B is of similar construction to the Sperwer A and uses a
similar fuselage design.
The air vehicle has distinctive double delta wings with clipped tips.
Swept canards are installed on the fuselage nose.
Take-off and landing of the air vehicle is fully automated with
catapult launch from the Sperwer pneumatic launcher and a
conventional automated landing with parachute and airbags.
The MC2555LLR launcher is supplied by Robonic Ltd of Tampere,
Finland.
9. CONTROL
Sperwer B has an advanced digital avionics suite with digital Ku
band (15GHz) datalink with a range of 200km, transponder / IFF
mode 3C and a VHF relay with air traffic control (ATC).
Sperwer B is fully compatible with the Sperwer A mobile ground
control station.
Two air vehicles can be controlled simultaneously from a single
ground station.
The ground station is provided with advanced technologies
including 3D mission planning, geographical information system
and connection and interoperability with C4I networks.
11. PAYIOADS
The system has embedded sensor to shooter capability. The double
delta wings can be fitted with under-wing pylons that can carry a
payload of 60kg (30kg each).
The lightweight pylons can carry rockets or air-launched missiles.
Weapon payloads could include the Rafael Spike-LR anti-tank missile
and the Bonus munition from Nexter / BAE Systems Bofors.
Spike-LR has a range of 4,000m and fibre-optic / imaging infrared
guidance.
Bonus is a 155mm munition with two sensor-fused submunitions and a
range up to 35km.
