This Catachan Valkyrie was on display at Warhammer World.
The Valkyrie are troop carrying gunships used by the Imperial Guard. They are used to take soldiers into the heart of the battle. Flying through the enemy gunfire, landing in the hotzone and dropping off their payload before flying up in support.
Sometimes the troops are jumping, using grave chutes, from high above the battlefield.
The Valkyrie is armed with lascannons or a multi-laser, and under the wings are missiles or rocket pods.
The Valkyrie, like most of the Imperium’s aircraft, is piloted and operated by the Imperial Navy, with a pilot, co-pilot and two door gunners.
There were some Tempestus Scions Valkyries on display as well.
The Tempestus Scions are elite special forces of the Imperial Guard. They have the best equipment and weapons.
Though not a helicopter, the Valkyrie is used in a similar way.
I do have one of these, but it currently remains unbuilt in its box. I did though paint some for Aeronautica Imperialis.
