On March 10,
1970, the Minister for Defence (John Gorton - Later Prime Minister Sir
John Grey Gorton) announced a comprehensive
helicopter acquisition program for the RAAF and the
Australian Army which was to include 84 Light Observation
Helicopters (LOH), 42 Utility Helicopters (UH) and 11
Helicopter Gunships. With the withdrawal of Australian
forces from Vietnam the LOH purchase was pared back to 75
Kiowa (subsequently reduced to 56) and the UH order to 14
UH-1H Iroquois (7 in 1970 for 5 Sqn, 2 replacements in
1971 for 9 Sqn in Vietnam and a final 5 delivered in
March 1974) plus 12 Ch-47C Chinook Medium Lift
Helicopters.
The 11 helicopter
gunships were intended to improve firepower and
battlefield surveillance capabilities for the Australian
Army and a budget of$13.2m was set aside for
acquisition. A final decision on the type of helicopter
to be selected was planned to be made in April 1970. The
two contenders were both from the Bell stable in the form
of the AH-1 Cobra and the armed UH-1 Iroquois
(similar to the Bushranger configured Hueys that 9 Sqn
had operated successfully in Vietnam).
In December 1970,
the AH-1G Huey Cobra was selected at a program cost of
$12.4m and the A16 serial prefix was allocated to the
type for RAAF service. It is probable that these aircraft
would have been diverted from the U.S. Army production
batch serialled 71-20983 to 71-21052 delivered in 1973.
A new helicopter
unit (8 Sqn RAAF) was to be formed but it had not been
decided whether the Cobras would equip 8 Sqn at
Townsville or be shared with 9 Sqn at Amberley.
As it turned out,
the RAAF AH-1G order was cancelled on October 7, 1971.
The Army tried to reverse the cancellation in support of
the RAAF given the experience gained in Vietnam. However,
it was not to be and the RAAF and Army soldiered on with
the UH-1H Bushranger until a dedicated type was selected
decades later in the form of the Eurocopter Tiger ARH.
Around 1992, there
was an rumour circulating around RAAF Amberley that there
had been some Cobras spotted sporting RAAF roundels.
These may have actually been visiting U.S. aircraft that
had been "zapped" with kangaroos!
