G 和 K 的争论很多人都认为 C-119飞行货车的炮艇机改型是是 AC-47的继承人,第二代炮艇机。但实际上,AC-130A 才是整个项目的第二步。导致这种误解的主要原因是,AC-119实际上比 AC-130更早投入使用,是它接替了AC-47在越南战场上的作战任务。实际上,在美国空军的正式项目编号里,AC-130研制项目被称为炮艇机-Ⅱ项目(ProjectGunship Ⅱ),AC-119才是炮艇机-Ⅲ Controversies between G and K Many consider the modification of the gunboat on the C-119 as a second-generation gunboat to the AC-47. But in fact, AC-130A is the second step of the entire project. The main reason for this misconception is that the AC-119 was actually put into operation earlier than the AC-130, taking over the AC-47’s combat mission in Vietnam. In fact, in the official Air Force project code, the AC-130 development project is called the Project Gunship II, and the AC-119 is a gunboat-III
