In addition to heavy ground units, the Iron Hands committed every available air and sub-orbital asset at their disposal to the Isstvan V drop. In the case of the Ferrum's complement, this primarily consisted of Thunderhawks and Caestus Assault Rams. Such vessels were utilised in a range of different roles, from that of gunship to ferrying troops around the battlefield directly in the face of enemy guns.

除了重型地面單位，鐵手軍團還執(zhí)行伊斯特萬五號空降任務時動用了他們所有可用的航空器與次軌道飛行器。就鐵拳號的補充而言，這些空運部隊主要由雷鷹和拳套突擊艇組成。這些載具有眾多不同的用途，從用作炮艇到直接面對敵人的炮火在戰(zhàn)場上運送部隊。

The ultimate fate of many of these aircraft is a salutary example of the spirit in which the Legiones Astartes were forged. Even as the full and dire extent of the rebel Legions’?treachery became clear, Loyalist Thunderhawks and other similar sized classes of aircraft worked tirelessly and entirely without consideration for their own safety to aid the beleaguered ground forces. Those aircraft that were able to do so launched ceaseless strafing runs against the enemy, while those whose ammunition was expended attempted to evacuate their brothers to orbit. Others fought desperately to fend off the attacks of enemy aircraft, while a few sacrificed themselves by crashing into the densest concentrations of enemy forces they could identify. Though noble in the extreme, such glorious acts of self sacrifice failed to stave off the death of the Primarch Ferrus Manus and the near total destruction of the ground forces so perfidiously betrayed in the Dropsite Massacre at Isstvan V

這些飛行器的最終命運是阿斯塔特軍團精神的有益范例。雖然叛徒軍團們叛變行徑的全面程度和可怕程度已經變得清晰，忠誠軍團的雷鷹和其他尺寸類似的飛行器們不知疲倦地工作著，他們奮不顧身地救援著被圍困的地面部隊。有能力的飛行器不斷對地面上的敵人發(fā)起掃射進攻，而其他那些耗盡彈藥的飛行器則試圖將兄弟們撤退到軌道上，其他人拼命抵抗敵機的攻擊，有些甚至犧牲自己撞向他們能識別出的最密集的敵軍。雖然忠誠派飛行員們極其高尚，但他們光榮高潔的自我犧牲未能延緩原體費魯斯 馬努斯的戰(zhàn)死以及在伊斯特萬五號登錄點大屠殺中遭到如此背信棄義的背叛的地面部隊那近乎完全的毀滅。
