Procurement of fighter aircrafts has always been a long, political, financial story in Austria, complicated by changes of parties in the government, The Northrop F-5 is no exception. Hereunder the details.
Tne
Austrian Air Force has had a long standing interest in the aircraft,
since the mid 60's, when the search for Saab J-29Ö fighter
replacement was started and the Northrop F-5A was oconsidered
together with
the Saab J-35. No decision at all was taken until 1970,
when an initial order for 20 Saab 105Ö was place, followed by
another order for 20 aircrafts.
Feeling
that the Saab was not suited for the air defence of the country,
another attempt to buy a fighter was started at the beginning of 1973
in view of procuring 18-24 aircrafts during the period 1974-76.
Candi-
dates under consideraton were the Saab 35X, the Mirage 5 optimised
for interception and the Northrop F-5E, all to new built aircrafts.
Information was even requested for the Mikoyan MiG-21 and MiG-23.
The
Northrop began to emerge as frontrunner after the demonstration
of Nrthrop F-5E 72-01390 at Linz-Hörsching in June 1973 after the
Paris-Le Bourget airwhow and quotation for 24 aircrafts with details of
delivery
requested dates by the Austrian Defence Department. A Letter
of Offer and Acceptance (expiring on January 1975) was sent by
Northrop. But, as usual, a final decision was postponed till at least
1976, but this year
passed without any decision.
A third attempt was started in 1978 with the shortlisting of 18 Northrop F-5E, Saab J-37Ö and Dassault 50, again without results due to financing problems.
Next attempt was in 1984; Austria hd devised a two-phase solution to its problem: buying 30 interim aircrafts cheaply as a stop-gap and then trading them back for a new generation aircraft in the early or mid-90'-.
Bristol
Aerospace offered initially ex RAF Jaguars to be replaced by Tornado
F.3 or Eurofighters; Saab-Scania between 24 and 30 ex Royal Swedish AF
J-35D Drakens, followed by Saab J-39 Gripen; General-Electric
had F-16/79 or F-16A for phase one and an option of the same aircraft for
phase two. Dassault was also present with refurbished Mirage III
initially, followed by Mirage 2000.
Northrop
was still interested in selling its fighter with a first phase proposal
for 12 new-build F-5E at a rather high initial cost of USD 173
millions, It had calculated that after six-and-a-quarter years use the
Tigers
could be resold for 88% of the original price. A cheaper
possibility would have been used Northrop F-5A coming at the time onn
the market. The Northrop F-20 would have been available for phase two.
The
Tiger offer was disqualified as Northrop refused to submit a fixed
price and contract disputes were to be settled by an USA court,
unacceptable for Austria.
As all earlier purchases had failed mainly due ro financial reasons an unorthodox proposal was submitted by Austrian Airlines for the purchase of the Northrop fighter: the airline would be willing to buy 16 Northrop
F-5E/F-5F aircrafts through its US subsidiary Austrian
Aircraft Corporation and lease them back to the Ministry of Defence,
also being responsible for their maintenance.
All
Northrops efforts were to no avail as the Austrian Ministry of Defence
decided to buy 24 secondhand Saab J-35D Draken, to be designated Saab
J-35Ö, on March 26th, 1985 for political (neutrality) and
financial
reasons. Northrop final offer for 16 aircrafts was higher than the Swedish one
(ASch 6,600 millions compared to ASch 2,700 millions) but the
life-cycle costs would cost some ASch 140 millions a year less to
operate
and would have lasted for 33 rather than the eight years in
service planned for the Saab J-35. The Northrop F-5 would also have a
75 percent residual value against none for the Saab aircraft.
Next
act of the Tiger saga happened almost by coincidence.The Drakens were
kept by far longer in service than the planned 8 years; on JUly 2nd
2002 the Austrian government announced the decision to buy 18
Eurofighter Typhoon (as usual after long political, financial and
popular discussions) as the new fighter. Delivery of them could only
start mis-2007 and an interim solution had to be quickly found for the
time starting
the withdrawal (2004) of th Saab J-35Ö operated and
the foreseen delivery date.
Next act of the Tiger saga happened almost by coincidence.
A
solution was found at a mid-February 2004 meeting between the Austrian
and the Swiss defence ministers. Switzerland was at the time
withdrawing 47 Northrop F-5E from use and 12 of these were to be leased
by
Austria for four years, with a possible extension of up to 2 years.
Voices that the Tiger had lost against the Draken the selection in 1985
were countered by the fact that it was on costs account. The contract
was
signed at the end of April 2004 with the Swiss armament agency
"Armaswiss" for the approximative cost of 15 millions Euros per year.
It included logistics for the main and the reserve bases
(Graz-Thalerhof and Linz-
Hörsching). documentation, armament,
training of flight and maintenance crews and maintenance of the
aircrafts itselves by RUAG in Emmen (Switzerland).
Also
included was modification by RUAG to add GPS navigation sets (Garmin
GPSMAP 295) and new communications sets (VHF/UHF). An ILS landing
systemm was also added due to mixed civil/military use of most
Austrian
airfields. Quick delivery of the first four aircraft was foreseen on
July 2004. All this subject to approval by the US governement, due to
the original transfer restrictions. Approval was granted on 14-07-04.
Ground
training (under the code name "Aquila") started on June 7th
for the first 4 of a total of 12 Austrian pilots at Dübendorf. Each
pilot had a minimum of 3'000 hours flying experience. Three flights
on Swiss F-5F followed,
starting from June 15th (one day after US
transfer approval!), first sollo flight for all pilots being on the
new fighter on 24th 2004.
The second batch of 4 pilots followed in
November 2004 and the third, again of 4 pilots, completed transition
on 24-03-06 at Emmen, some of the last being former Saab 105Ö
pilots, all other being former
Draken pilots.
The selected
airframes had in the meantime undergone modification af RUAG's
factory in Emmen and first ones were ready for delivery according
plans. Camouflage remained the same as Swiss aircrafts, only visible
change were the Austrian nationality markings.

The first
four aircrafts (J-3005, J-3030, J-3033, J-3065) were finally
delivered from Emmen to Graz-Thalerhof on July 7th 2004, while the
official handover ceremony took place at Graz on July 9th,
2004.

The
Überwachungsgeschwader - 2. Staffel (Surveillance Wing - 2nd
Squadron / Serials page code: 2 Sqn) at Graz-Thalerhof was selected
from the very beginning to re-equip with the former Swiss aircrafts,
at the time
equipped with Saab 105Ö in charge for training,
VIP transport with specially modified aircrafts, air traffic
control/interception and target-towing for the Saab J-35ÖThe Tigers.
With
the arrival of Northrop F-5Es additional local pilot training could
be undertaken, but, as no live-firing range is available in
Austria, Swiss shooting-ranges had to be utilised. Two courses
were organised, the first
started on 21-02-05 and lasted till
04-03-05 with F-5E serials J-3004/05/30/38/52/57; the second one
ending in May 2005 with F-5E serials J-3014/36/41/30/33/56. The
Tigers were transferred by Swiss personnell as
Austrian pilots not yet
in a position to fly from country to country. Another source mentions
that this happened for two weeks between February and March 2005.
Northrop F-5E
J-3058 at Sion on 25-02-05 still without IFR antenna on tail, but
with Squadron badge. The
inscription "CALL 121.5 MHz " was added on aircrafts'
underbelly tanks to instruct civilian
aircrafts
infringing the local
"no-fly" area during the WEF congress, mainly in January each Year.
On
July 1st, 2005 the 2. Staffel was officially entrusted with
armed air-defence of the Austrian airspace, keeping a flight of
two aircrafts
based at Linz-Hörsching (plus 1 reserve), while while the Draken era
ended officially
on November 25th, 2005, though some J-35Ö remained operational till
the end of 2005, flying aggressors missions against the
F-5Es.
The
beginning of 2006 Staffel saw the first operational test. In
collaboration with the Swiss AF, it undertook 57 flights between
January 25th and January 29th,
policing
the Austrian sky next to Davos (Switzerland)
during the World
Economic Forum (WEF) meeting.

Same procedure was in use while
Austria was holding the presidency of the European Community in 2006
and several European ministerial meetings that took place on Austrian
soil.
Laage in Germany was the destination of the only trip
abroad on 18th and 19th August 2006. This base houses the first
German AF Typhoons unit, Jagdgeschwader 73 "Steinhoff", and
it was surely interesting to
visit the operator of the future
Austrian fighter aircraft.
An
annually repeating Austrian AF task is the protection of the airspace
around Davos (Switzerland) when the World Economic Forum takes place.
The F-5s participated with "CALL 121.5 MHz" inscription
tanks for
the 2007 (24-28 January) and 2008 (23-27 January) flying
from Graz, together with Pilatus PC-7 and
helicopters.

Unfortunately,
some accidents have been reported, luckily all of them with minimum
damage and without serious consequences:
September
19th, 2006: F-5E J-30XX
slid
off-runway at Linz-Hörsching on take-off, slight damage to
the undercarriage.

BADGES / PATCHES
END
OF AN ERA
The
end of the Tiger era begun on July 12th, 2007 when Eurofighter
Typhoon 7L-WA landed at Zeltweg.
Fifteen
Eurofighters Typhoon (reduced from 18 originally on order) equip
the Überwachungsgeschwader-
1. Staffel (Surveillance Wing 1st
Squadron) at Linz-Hörsching and the Tigers have been returned to
Switzerland.
Final active
operation of the Tigers was the control of Austrian sky during the
European Football Championship in 07-7 till 28-06-08, together with the Saab 105, the Pilaus PC-7 and an
array of
helicopters. Two Northrop F-5E took care of Quick Alert
Reaction (QRA) at Graz-Thalerhof until 29-06-08, two Eurofighter
based at Zeltweg have replaced them from 01-07-08.
The
return flight of the first 4 to Payerne (J-3004, J-3033, J-3052,
J-3056) has taken place on 30-06-08, when the contract ended.
Remaining
8 aircrafts landed on 22-07-08 (two at Emmen, 2 at Payerne) and on
24-07-08 (4 at Payerne).
