This quote didn't tell us what does exactly unstable mean here?here was no horizontal tailplane, even though Saab engineers had considered fitting one. A few wind tunnel models were built with tailplanes, but during wind tunnel testing it was found that this configuration was unstable, and so the tailplane was dropped.

I am not qualified to answer this question,but we can send here some SAAB-35

kaiserbill said:Maybe export orientated, but then Sweden was notoriously fickle about who they would sell jet fighters to.

kaiserbill said:Thanks Abe.
kaiserbill said:I guess I was simply looking at the physical dimensions of the J-79 vs the RM6 as well as thrust. The J-79 is about 2 meters longer than the RM6, about 10% wider, and almost half a ton heavier, for roughly the same thrust. I think it has a higher airflow requirement too.
kaiserbill said:I would guess that would require a massive redesign to the aft-of-cockpit fuselage internal structure, as well as centre of gravity considerations...etc
kaiserbill said:Hence my pondering wonderment at benefits.
kaiserbill said:Thanks for the info on the Swedish defence export issue. Whilst being aware of Palme's odd foreign policies, I wasn't aware of his mentors/predecessors relative real politik.
kaiserbill said:Not to derail, but a quick question: Do you know what requirement the Lansen was aimed at to compete in South Africa? Was it a strike or intercept role? Trying to figure whether it was aimed at competing against the Mirage III/Sabre/Buccaneer/Canberra, all of which were SAAF projects/purchases in the late 50's/early 60's.

Abraham Gubler said:This well-known phenomenon only developed at a later date. Before the succession of Olof “US Bombing of Hanoi in 1972 is another Katyn or Sharpeville Massacre” Palme to the Prime Ministerial office (in 1969) his mentor Tage Erlander was far less romantic in foreign affairs. Sweden extensively tried to sell their domestic weapons abroad in the 50s and 60s. They were even quite upset when they failed to sell the Lansen strike fighter to South Africa.
Saab marketed Lansen during 1953-54 to Norway, Denmark, The Netherlands, Switzerland, Yugoslavia, Argentine, Venezuela and India.
India were somewhat interested in licence production of 25-40 Lansens at HAL. Saab delivered an offer in 1954. Interest increased in 1957 when series aircraft had flown and India then discussed a purchase of 10 photo reconnaissance and 20 fighter-bombers followed by licence production of 300 more. India purchased British aircraft instead.
South Africa also seriously discussed Lansen but never bought any (possibly because Saab didn't have export experience, possibly because the Swedish air force wanted their Lansens first and happily payed more even though they'd be cheaper with a larger production run, reasons which aren't unique for this case).
Pilots from the Finnish air force flew S 32C in 1957, but they really wanted fighters, so this was hardly a part of a genuine export drive.
Its performance is also quite impressive. Like a Mirage III but much tougher, with far better avionics and able to land and takeoff in a WWII standard 3,000 foot runway.
