Description: The Astra-Romana, Phoenix (Orion) and Lumia Group of refineries (White IV) were the most important target of the mission, with 10 key installations to attack. The target was attacked by the 98th Bomb Group. The damage report, published on 5 August 1943 determined that: 'Damage to this group of refineries is considerable, but although production will be curtailed, it is not sufficient to cause complete stoppage after the few weeks necessary for essential repairs to be carried out have elapsed. This is due to the fact that in the ASTRA ROMANA Refinery the boiler house does not appear to be unserviceable, though it may have suffered minor damage from the fire in the McKee Plant about 15 yards away, and that, while the two most important furnaces in the McKee Plant itself are damaged beyond repair, the old distillation plant appears to be untouched. Damage seen to the Lubricating Oil Plant will probably cause a slight curtailment of production of this type of oil. 15 tanks of various types have been destroyed and one damaged, but this will not affect the working capacity of the plant. In the PHOENIX (ORION) Refinery damage to the boiler house will have caused the loss of approximately one third of the steam generating capacity, resulting in a corresponding loss of production over a considerable period. Damage is also noted to the power plant, but its extent and effect of the working capacity of the plant cannot be gauged. 4 tanks have been destroyed and 2 damaged. The LUMINA Refinery is untouched except by one bomb which has exploded in the railway sidings severing one or two tracks.'

Description: The Concordia Vega refinery (White II) was the second most important target of the mission, and attacked by aircraft of the 93rd Bomb Group. The damage report, published on 5 August 1943 determined that: 'Damage to this plant is confined almost entirely to the destruction of tanks. 6 large storage tanks with a capacity of probably 5,000 tons each have been destroyed, while in the groups of sunken process tanks within the works, 11 have been destroyed and 4 to 6 damaged. One of the distillation plants appears to have suffered fairly heavily, but not sufficiently to affect the output of the refinery to any serious degree.'

Description: The Steaua Romana Campina pumping station (Red), close to the Concordia Vega refinery was the fourth most important target of the mission, it was attacked by the 389th Bomb Group. The damage report, published on 5 August 1943 determined that: This small plant situated near the VEGA refinery (CONCORDIA) has been severely damaged, but the installations are such that they can be fairly quickly replaced. the two pump houses and one storage tank have been destroyed.'

Description: The Standard Petrol Block at Unirea Speranta (White III) was the fifth most important target of the mission, it was attacked by components of the 93rd Bomb Group. The damage report, published on 5 August 1943 determined that: 'Slight damage is noted to 2 large storage tanks and to a building in the CONCORDIA Munitions Works on the opposite side of the railway. The appearance and scattered nature of this damage, together with the complete absence of craters in the vicinity, suggest that it is due to earlier raids and that this plant entirely escaped damage during the attach of August 1st.'

Description: The Creditul Minier Refinery at Brazi (Blue) was the sixth most important target of the mission, it was attacked by the 44th Bomb Group. The damage report, published on 5 August 1943 determined that: 'Apart from damage to 20 storage tanks of varying capacities and to railway tracks on the outskirts of the plant, no statement can be made on the limited cover available.'

Description: The Columbia Aquila Refinery (White V) was the fifth most important target of the mission, and was attacked by components of the 44th Bomb Group. The damage report, published on 5 August 1943 determined that: 'Damage to this plant is so intense that almost complete rebuilding would be necessary before it could resume operation. The crude oil distilling plant has been devastated by fires and explosions while the cracking plant and stablisier installation have been damaged on slightly less seriously. the boiler house appears damaged. Nine storage tanks and at least 9 process tanks have been destroyed. Other damage is located among workshops, offices, compressor buildings and storehouses, while some damage has been done to railway tracks and rolling stock. the number of craters seen outside the target area is small.'
