|Page 1 (2)|
The SH 89 is an aircraft
primarily for antisubmarine operations, but is also used for sea
surveillance and transports. The
SH 89, a variant of the well-known Spanish CASA Aviocar, (the
manufacturers designation is C-212-300), was provided to the Air Force
in 1986. On the same time, the Swedish Coast Guard bought three similar
aircraft for sea- and fishing zone supervision.
The SH 89 is equipped
with a radar type PS-864 in the nose. The radar is used for the
searching of small objects (like the periscope of a submarine) at the
surface of the sea. It is also used for navigation and to fix the
position of ships. Hydrophone buoys are carried and can be dropped in
the reconnaissance area. The buoys transmit sound signals to the
operators in the aircraft. With help of a computer system,
they can compare the sounds from the buoys with the earlier
recorded sound of different submarine types.
Another aid is the FLIR (Forward
Looking InfraRed) system, that is used to search for objects as
submarines under the surface. The system indicates differences of
temperature of the water, which follows the wake of a submarine. Other
equipment includes a SLAR (Side-Looking Airborne Radar), camera
equipment and microwave radiometer.
The SH 89 has crew of five – two pilots, one flight engineer, one
hydrophone operator and one system operator, who also leads the tactical
