The Harrier Aircraft: An Overview
When it comes to jet-powered attack aircraft capable of Vertical/Short Takeoff and Landing (V/STOL) operations, the Harrier stands out as a remarkable and pioneering design. Developed by British manufacturer Hawker Siddeley in the 1960s, the Harrier was specifically designed to operate from improvised bases without the need for large and vulnerable air bases.
Introduction to the Harrier
The Harrier, named after a bird of prey, was a groundbreaking aircraft that revolutionized military aviation. Its ability to take off and land vertically or in short distances made it highly versatile and adaptable to various operational scenarios. Originally conceived to operate from improvised bases, such as car parks or forest clearings, the Harrier was later adapted for use from aircraft carriers, further expanding its range of missions and capabilities (Wikipedia).
Evolution and Advancements of the Harrier
The Harrier family includes two generations and several notable variants. The first generation, consisting of the AV-8A and AV-8C Harrier, served multiple air forces, including the Royal Air Force (RAF) and the United States Marine Corps (USMC). These early Harrier models displayed the aircraft’s exceptional V/STOL capabilities and marked its successful entry into service.
In the second generation, which emerged in the 1980s, two primary variants were developed: the AV-8B Harrier II produced in the United States and the British Aerospace Harrier II manufactured in Britain. These second-generation Harriers incorporated advancements in avionics and weapons systems, enhancing their tactical capabilities. The AV-8B Harrier II became the primary choice for the USMC, while the British Aerospace Harrier II found favor with other operators as a replacement for the first-generation models.

It excels in providing close air support to ground troops and conducting armed reconnaissance. With its V/STOL capability, the Harrier can operate in challenging environments and provide rapid response and flexibility on the battlefield.
The AV-8B Harrier II is employed by the United States Marine Corps (USMC), the Spanish Navy, and the Italian Navy, as stated by Wikipedia. These operators utilize the Harrier’s capabilities to carry out a range of missions, including air-to-surface attacks, air defense suppression, and battlefield interdiction.
Operators and Service History
Throughout its history, the Harrier aircraft has been operated by several nations worldwide. As of 2012, the active service operators include the United States Marine Corps (USMC), the Spanish Navy, and the Italian Navy, as stated by Wikipedia. Other operators, such as the Royal Air Force (RAF) and the Royal Navy, have retired their Harrier variants.
The Harrier has demonstrated its operational effectiveness in various conflicts and military operations. It has seen action in the Falklands War, the Gulf War, and more recently, in Afghanistan. The Harrier’s successful service history showcases its adaptability, versatility, and reliable performance in combat situations.
By understanding the vertical/short takeoff and landing capabilities, the tactical applications, and the operators and service history of the Harrier aircraft, one can appreciate the unique characteristics and significance of this remarkable military aircraft.
The Development of the Harrier
The Harrier, a remarkable aircraft known for its Vertical/Short Takeoff and Landing (V/STOL) capabilities, has a fascinating development history. Let’s explore the collaborative efforts and project initiation, the P.1127 prototypes and RAF order, as well as the Pegasus engine and design adaptations that contributed to the creation of this innovative aircraft.
Collaborative Efforts and Project Initiation
The development of the Harrier was made possible through collaboration between the British aero engine manufacturer Bristol Engine Company and Hawker Aircraft. In the 1950s, various aircraft companies were exploring vertical take-off and landing (VTOL) capabilities due to the aftermath of the Korean War. The Bristol Engine Company developed a vectored thrust engine named Pegasus, while Hawker created the design for an aircraft to meet an existing NATO specification for a “Light Tactical Support Fighter” (Wikipedia).
This collaborative effort between the two companies laid the foundation for the development of the Harrier, a groundbreaking aircraft that would revolutionize V/STOL capabilities.
The P.1127 Prototypes and RAF Order
The P.1127 prototypes played a crucial role in the development of the Harrier. These prototypes attracted the attention of the Royal Air Force (RAF) for a V/STOL ground attack aircraft. The success and potential demonstrated by the P.1127 prototypes led to an order from the RAF for further development and production of the aircraft. This marked a significant milestone in the journey of the Harrier, as it gained official recognition and support from a renowned military force.
The Pegasus Engine and Design Adaptations
At the heart of the Harrier’s exceptional V/STOL capabilities lies the Pegasus engine. Developed by the Bristol Engine Company, the Pegasus engine utilizes vectored thrust technology, allowing the aircraft to direct its engine thrust vertically during takeoff and landing. This innovative engine design enables the Harrier to operate from improvised bases and smaller airfields, eliminating the need for traditional runways (Wikipedia).
Throughout the development process, the design of the Harrier underwent several adaptations to optimize its performance and ensure its suitability for various missions. These design adaptations included modifications to the aircraft’s structure, aerodynamics, and controls, all aimed at enhancing its V/STOL capabilities and overall operational effectiveness.
The collaborative efforts between the Bristol Engine Company and Hawker Aircraft, combined with the success of the P.1127 prototypes and the advancements made in the Pegasus engine and design adaptations, culminated in the creation of the remarkable Harrier aircraft. Its unique capabilities and groundbreaking technology have solidified its place in aviation history as a true pioneer in the field of V/STOL aircraft.
