|S 31 – Supermarine Spitfire PR Mk XIX (1948-1955)|
|Page 1 (1)|
PR.XIX was the last unarmed reconnaissance variant of the
well-known Supermarine Spitfire. Totally 225 were built. Fifty
of these were bought, nearly new and in excellent condition,
from the RAF in 1948. They were all provided
to the Reconnaissance Wing F 11 at Nyköping Their Swedish
designation became S 31. The
aircraft were delivered complete with camera installations and spares.
The S 31 carried three cameras. One oblique camera type SKa 12 was always fitted. The other two were either two telephoto cameras type SKa 10 or one SKa 10 and one SKa 12.
Ska10 could be fitted with lenses of 50 cm alt. 92 cm focal length. Most
missions were therefore flown at
an altitude of 5.000 alt. 9.200 metres, giving the photographic film a
scale of 1/10.000 metres.
PR missions used to contain a moment when the aircraft took a main
series of photographs while flying right above the target. The S 31 with
its side camera was safer as earlier Swedish P.R. aircraft, as the
initial oblique photos could be taken from a safe distance of a
S 31 was fitted with a Rolls-Royce Griffon 12-cylinder liquid-cooled 66
engine developing 2.055 hp. The aircraft had a pressurized cockpit.
Chief of the Swedish Air Force 1942-1954, General Bengt Nordenskiöld,
ordered that the Air Force only should look forward. No photos from old
times should be saved. Aircraft which have served its time should be
sold or scrapped. Fortunately, a few colonels took care of old aircraft
from their Wings in spite of the order. But all S 31s were scrapped. The
Spitfire on the photo has served in Germany and India, returned to
Britain and later sold to Canada. After a lot of difficulties, it was
brought to Sweden in bad shape, but after an extensive work, it has been
rebuilt to full S31 standard. It was committed to the Flygvapenmuseum
(the Swedish Air Force Museum) in 1989. The original Spitfire was
once RAF PM627 (C/n 6S-699626) and carries now the fictive RSwAf Number
