1. Development and History

Boeing AH-64 Apache Helicopter
The AH-64 Apache, originally known as the Model 77, began its journey in the early 1970s. Hughes Helicopters developed it to meet the U.S. Army's need for an Advanced Attack Helicopter (AAH). The prototype, designated YAH-64, first took to the skies on September 30, 1975, marking a significant milestone in helicopter development.

In 1976, the U.S. Army chose the YAH-64 over its competitor, the Bell YAH-63. This decision allowed Hughes Helicopters to start full-scale production. McDonnell Douglas acquiring Hughes Helicopters in 1984 brought more resources and expertise to improve and manufacture the Apache for military use.

Key milestones in the development process

  • 1972: Hughes Helicopters starts work on the Model 77.
  • 1975: The YAH-64 prototype conducts its maiden flight.
  • 1976: U.S. Army selects YAH-64 over Bell YAH-63.
  • 1982: Full production approved by U.S. Army.
  • 1984: McDonnell Douglas acquires Hughes Helicopters.
  • 1986: Introduction of AH-64 Apache into U.S. Army service.

After acquiring Hughes, McDonnell Douglas focused on improving the helicopter's capabilities, contributing significantly to its current status as a powerful attack platform. In March 1997, they introduced the advanced AH-64D Apache Longbow variant with better targeting and survivability features.

The transition from McDonnell Douglas to Boeing Defense, Space & Security happened in 1997 when Boeing merged with McDonnell Douglas. Since then, Boeing has continued to innovate and enhance the Apache platform, ensuring its relevance in modern warfare situations.

The development and history of the AH-64 Apache showcase a collaborative effort among key aerospace players like Hughes Helicopters, McDonnell Douglas, and Boeing Defense.
