10401

This is indeed a very impressive image. The Boden based 1st Helicopter Squadron had five helicopters at the time, and it held the rescue alert for entire northern Sweden. Four of the Super Pumas used to be based at the Boden base and one was based at the F4 Frösö Air Force base in Östersund. The image was shot as all five aircraft were gathered at the home base. A sight like this is extremely rare.

Both bases are now closed and a couple of the machines have been moved to the F21 Air Force Base in Luleå. The rest of them have been transferred to southern Sweden.
H-91 ditched in the water south of Ronneby in November of 2005. All occupants survived.

The helicopters visible in the image are most likely 10401, 10403, 10407, 10411 and 10412 (not mentioned by order).
