You read that right! This is not Thunderhawk! Neither Storm Hawk nor Storm Raven!

It is the largest support combat unit in the air, the Stormbrid Thunderbird (it doesn't look domineering if it is directly turned into a storm bird), except for the battleship!

The Thunderbird (officially designated by the Cult of the Mechanicus as the Warhawk VIdropship) was used by the Astarte Star Marine Legion in warfare during the Great Expedition and the Great Horus Mutiny of the 30th and 31st millennia as the primary means of transporting troops and air support. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoBefore the advent of Thunderhawkgunship, it was considered the key to any Space Marine legion, due to its ability to play a huge role in many combat positions. The Thunderbird Stormbird can undoubtedly be used as an orbital transporter, a heavy ground attack aircraft, or a bomber. This vehicle can quickly transport Space Marines from orbital battleships to the scorching heat of a battle. At the same time, it can provide supporting firepower against enemy targets from the air and from the ground.

The Thunderbird Stormbird is far larger and bulkier than the Thunderhawk, and it lacks flexibility in combat. However, the Thunderbird Stormbird can transport a standard company of Space Marines, about 60 to 100 Space Marines, which is far beyond the transport capacity of the Thunderhawk. It has missile launchers under the wings on both sides, and a powerful kinetic cannon mounted on its nose. Two Space Marines seated back-to-back piloted the behemoth, assisted by two Caboots in the container. The true face of the Thunderbird is not well known, as early Thunderhawk drawings show its huge, vertical take-off and landing capabilities, as well as its huge loading capacity to transport Space Marines from the Imperial landing barge to their destination, the Thunderbird Stormbird should look similar to these early Thunderhawks, but much larger!

The Stormbird, which can navigate both vacuum and atmosphere, was born on Earth (Terra) and was created by a political group called the Yndonesic and used in the Unification Wars against another tribe called the Panpacific. It was widely used throughout the Great Expedition, although during the Horus period, most legions had switched to the smaller and more nimble Thunderhawks, and TheLuna Wolves were the few legions that still deliberately used the Stormbird because they could send them into battle at the beginning of the battle. A Stormbird is piloted by two Space Marines seated back-to-back, assisted by two Mechs in a container.

As an aside, theUnificationWars is the general term for the AgeofStrife, a warlord war between the Earth's warlords and a chaotic war between the 25th and 30th millennia, and it is at the end of this Unification Wars that our wise Emperor leads the first generation of genetically modified warriors: the ThunderWarriors Unified the earth and established the empire of mankind.

During the Great Horus Mutiny, Captain Nathaniel Garro, the former commander of the Legion Company, under the direction of the Imperial Prime Minister MalcadortheSigillite, used the Stormbird to visit many planets, just like Garro's Power Armor, which no longer had any legion logos and colors, and only turned a uniform gray.

Starting with the Horus Rebellion, Chaos Space Marines (such as Eat the World) still use the old Stormbird Thunderbird.
