However, it is Chemring's contention
that optimum performance can only be
achieved if chaff payloads can be placed
at exactly the right point in time and
space. "Maximizing the capabilities of
both current and future products to
meet the current and future threat scenarios critically depends upon accurate
positioning of the deployed decoy or
individual placement of submunitions,"
says Steve Kerchey, the company's senior business manager (naval). "This is
because modern missiles have very small

range gates. So, no matter how realistic
the decoy, it will be ineffective unless
it is in the right place for the missile to
'see' it."
He adds, "Fixed launchers have long
proliferated, but they suffer from a
number of limitations. They have no
positional capability; offer low coverage; require ship maneuver; and do not
fully exploit the performance of the decoy round."

need for greater payload placement accuracy to improve effectiveness against
evolving seekers."
Chemring undertook a market survey to identify options for a trainable
launcher system - able to position in
both azimuth and elevation - compatible with its range of 130-mm decoy
munitions. Unable to find an off-theshelf solution, the company chose to
pursue the private venture development of its own CENTURION system.
This is a trainable, stabilized launcher
featuring 12 vertically-stowed 130-mm
barrels, fitted atop a rotating plinth,
with each barrel able to depress to the
desired firing angle.
Response time is less than 3 seconds
from the stow position, with angular
accuracy maintained through compensation for ship movement. This, in
combination with the latest variablerange decoy rounds, allows payload
placement to be controlled in three axes
so as to give improved ship signature
replication.
CENTURION has been engineered to
ensure all soft-kill rounds are available
for all engagements. Another advantage of the design is that it allows munitions to be fired at a far wider range
of elevations. For example, higher
angles of elevation (up to 80 deg) offer improved protection against "high
diver" attacks, while launch at lower
ballistic elevations may reduce the
time of flight for distraction payloads
by several seconds.
CENTURION also addresses the need
for the associated development of optimized launch control algorithms and
the integration of a new generation of
variable-range decoys. "The launch algorithm will take into account ship
heading, speed, wind and bearing, the
threat bearing, and the type of threat,"
says Kerchey. "The wide training angle
frees the command from having to consider changes to the ship's course to
achieve the optimum firing solution."
"The important thing here is to make
an accurate calculation so that the decoy payload is released at the right
range, at the right time, and in the right
shape. It is vital that the missile seeker
logic 'sees' a realistic pattern which it
does not reject." - R. Scott a
