Ammunition,
explosives and the environment may seem like an unlikely combination
but that is what Lancelin Naval Gunfire Support Range has managed
to blend.
Situated on one of the most beautiful coastlines in Australia,
the range is approximately 150km north of Perth; about three and
a half hours drive from HMAS Stirling.
The range is half way between the town of Lancelin renowned for
its fishing and perfect windsurfing conditions and the crayfishing
community of Wedge Island.
And while many readers will be familiar with being on the firing
side of Lancelin, there are only a few who will have experienced
what it’s like to be on the range itself.
LCDR Peter Radburn, HMAS Stirling’s Gunnery Officer said that
the edge of the range, used by Defence since pre WWII, is 25 km
north of Lancelin, with the southern tip of the impact area a
further 5 km north.
This 30 kms to the impact area takes an hour to negotiate because
of the sand dunes and rocky limestone outcrops.
“The front of the range has 25 kms ocean frontage and the depth
of the range goes back about 12 kms and tacked onto the back of
that is a military exercise area,” LCDR Radburn explained.
“The Navy owns an impact area approximately 8 kms wide across
the front facing the beach and about 10 kms deep.
“In there we have eight targets, six of which are gunnery targets,
that is shore bombardment targets, and two which are aerial bombing
targets.”
The ground along the coastline and the area at the back of the
range consists of sand dunes while the middle of the range, where
the bombardment and bombing occurs, is limestone and very low
scrub.
The original targets the ships fired at were old buses. Now the
targets are coppers logs wrapped in orange bunting.
The bright colour is not so the ship can see the target but rather
to ensure the range spotters in the observation tower can see
them.
“The forward artillery spotter/ range safety officer (RSO) sits
in the observation post just outside the impact area and gives
ships grid coordinates for the onboard navigation and bombardment
teams so they can complete their calculations and ensure their
rounds land on or as close as possible to, the target.”
The RSO will give spotting corrections to the ship calling the
fall of shot until the projectiles are impacting within 50 yards
of the target.
They will then be instructed to ‘fire for effect’.
When that happens the ship expends the rest of the allocated munitions
onto the target.
A computer program assesses and records such factors as the “time
call to ready” and a range of calculations the ship must apply
and the amount of reaction time.
The ship receives a score at the end of the serial which is sent
to the RAN trials and assessing unit (RAU) in Sydney.
“They can tell if the ship has an accurate gun system and a ‘swept
up’ gun team and plotting team.
The points go towards things such as the Gloucester Cup and Gunnery
shields but NGS (Naval Gun Fire Support) is just a small part
of Naval Gunnery.”
The Navy has a demolitions area and bunker within the Lancelin
impact area, used mainly by Australian Clearance Diving Team Four
and occasionally the Army Engineers.
But the range itself is used for a variety of purposes such as
tactical explosive ordnance disposal as well as the demolition
of obsolete ordnance.
Counter-terrorism training and SAS Cadre courses are also conducted
on the range.
When the range is activated, approximately 16 support people deploy
from Stirling.
Sentries are posted well before any serial start time to ensure
there are no members of the public on the range.
Additionally well before any range activation, a notification
will go in the papers as well as warnings to mariners and aircraft.
Notices also go to other groups such as tour agencies.
“When the range isn’t active, all of the range, with the exception
of the impact area, is open to the public.
We discourage people from going off the main tracks for environmental
reasons and the fact there may be unexploded ordnance,” LCDR Radburn
said.
The Lancelin gunnery range has been the subject of environmental
concerns for some time, but Navy, who must strictly adhere to
an environmental management policy, is working closely with the
local residents to allay concerns.
“Up until two years ago, there was a lot of animosity between
locals and Defence but now we are working with the locals to achieve
the Navy training serials with minimum impact on the public and
the environment and the public appreciate the fact that we have
their interests in mind.
“A positive step towards Defence working with the local community
is the formation of the Lancelin Management Advisory Committee.
“Every three months we have a meeting with representatives from
Defence (including Defence environmental management), the Lancelin
and Wedge Island communities, regional shires, CALM, FESA, Fisheries
(Rock Lobster and recreational), Bee Keepers and WA Wild Flower
Pickers associations.
“`At the meetings, any ideas or concerns can be raised and hopefully
resolved.
It’s working quite well and we have established a good working
rapport.”
The next major range activation will occur later this year in
support of Principal Warfare Officer (PWO) Sea Week as well as
individual ship work-ups.
