AJS 37 Viggen, conversion of three versions into one
(This information is from issue 2/91 of FlygvapenNytt, the
magazine of the Swedish Air Force.)
The new anti-ship missile Rb 15F has already been purchased. To enable
the Viggen to carry it, the computer has to be upgraded and fitted with
a multi-processor unit and a databus introduced. Together with this
modification, it is a small matter to give the aircraft a TRUE multi-role
capability (which was envisioned in 1972, when it entered service).
Future pilots are also supposed to be multi-role.
The computer upgrade also allows transfer of large amounts of data between
the mission planning and evaluation system (FASA).
ADVANTAGES
- More aircraft available for large scale attack missions.
- Better air defence coverage of Sweden.
- Faster evaluation of reconnaissance missions.
- You can get high quality reconnaissance data from any mission.
- To eliminate one component, ALL aircraft in the AJS system
must be destroyed by an attacker.
- Since FASA is used to evaluate all missions in detail, including
air combat between several aircraft (something which in other air forces
has to be done on instrumented ranges with external data pods), it
is very suitable to evaluate new threats in wartime. (And I wish to
point out again that you use the SAME computer to plan your next mission.)
- Economic usage of airframes. When attack squadrons are supplied
with JAS 39 Gripen, their Viggens can be used in recce squadrons.
- Easier introduction of Gripen in squadrons, since the new operational
philosophy is what you need to make full use of that aircraft's capability.
WHEN?
It has already begun.

Very likely the photo reconnaissance pod for JAS 39 Gripen
will be used on versions AJ and SH.
Some loads shown in pictures or mentioned are
6 * 24 + E
2 * 24 + 2 * 05 + 2 * 74 + E
2 * 24 + 2 * C + 2 * 05
4 * BK + 2 * 24
4 * 24 + 2 * 15 + E
Not necessarily typical, but _changes_ from what was possible before.
(Fighter/attack, not included in the AJS-upgrade programme since it
already is more modern than the older aircraft. It is of course also
upgraded all the time.)
