USS Iowa (BB 61) ramming powder bags, DN-SC-91-03644 - The gun captain of the center Mark 7 16-inch/50-caliber gun in the No. 2 turret aboard the battleship USS IOWA (BB-61) gives the signal to ram the powder bags on the spanning tray into the gun's chamber. The crew is loading what will be the 1,000th round fired by the IOWAs 16-inch guns since the ship's recommissioning.  The panel opposite the gun captain with the red line is the door to the powder hoist from which the bags are delivered to the gun from the powder room at the base of the turret.  At left, the rammerman operates the lever which uses hydraulics to ram the projectiles and powder bags into the gun's breech.  The rammerman must carefully operate the ram lever as an overram could jam the powder bags and/or projectile too far into the gun, causing a dangerous situation.  On 19 April 1989 this same gun exploded and killed 47 crewmembers in the turret.  The explosion is theorized to have been caused by an overram of five bags of D-846 powder., Finally, the rammerman, at left, operates a lever which uses hydraulics to ram the powder bags into the gun's breech. The spanning tray is then folded out of the way and the breech block is closed and locked.Schwoebel, pp. 4–6, 89.

アイオワ乗組員は、IOWAs 16インチ砲が発射した1,000発目の砲弾を、艦の再就役以来の装填を行っている。赤いラインで銃の隊長の反対側のパネルは、砲塔の根元の火薬室からバッグが銃に届けられる火薬ホイストへのドアです。左のラマーマンは、油圧装置を使用して発射体と火薬袋を銃の後部に挟み込むレバーを操作する。ラムレーバーは、火薬袋や発射物が銃に詰まりすぎるため、慎重に操作しなければならない。1989年4月19日、この同じ銃が爆発し、砲塔にいた47人の乗組員が死亡した。爆発の原因はD-846の5つの袋のオーバーラムによると理論づけられている。最後に、ラマーマンは油圧装置を使用して火薬袋を銃の後部に挟むレバーを操作する。次に、スパンニングトレイを途中で折りたたんで後続ブロックを閉じロックする。Schwoebel, pp. 4–6, 89.
