The AH-64D Longbow Apache is currently the most advanced, the most versatile and the most powerfully armed combat helicopter in the world. This upgraded version of the Apache was used extremely effectively by the US Army in the Gulf Wars of 1991 and 2003. The long-range radar can be used for its own protection, but it is also capable of accurately acquiring up to 1000 potential targets and identifying 128 opponents as well as automatically determining the priorities for up to 16 Hellfire missiles in attack mode.
