A12 vs SR71 Speed Comparison

Introduction to the A12 and SR71

The Lockheed A-12 and the Lockheed SR-71 are two of the most iconic and secretive aircraft in the history of aviation. Both were designed by Lockheed’s Skunk Works division, led by the legendary Clarence “Kelly” Johnson. The A-12 was a precursor to the SR-71, and both aircraft were designed for high-speed, high-altitude reconnaissance missions. In this article, we will explore the speed comparison between the A-12 and the SR-71, two of the fastest aircraft ever built.

Design and Development of the A12 and SR71

The A-12 was the first of the two aircraft to be developed, with the first flight taking place in 1962. The A-12 was designed to be a high-speed, high-altitude reconnaissance aircraft, capable of evading enemy defenses. The aircraft was powered by a single Pratt & Whitney J58 turbojet engine, which produced 32,500 pounds of thrust. The SR-71, on the other hand, was developed in the late 1960s and made its first flight in 1964. The SR-71 was also powered by the J58 engine, but with a number of improvements and modifications to increase its speed and altitude capabilities.

Speed Comparison

The speed of the A-12 and SR-71 is a matter of great interest and debate. The A-12 was capable of reaching speeds of over 2,200 mph (3,540 km/h), while the SR-71 could reach speeds of over 2,500 mph (4,020 km/h). The SR-71 was also capable of reaching altitudes of over 85,000 feet (25,900 meters), while the A-12 could reach altitudes of up to 80,000 feet (24,400 meters). The speed and altitude capabilities of these aircraft were made possible by the use of advanced materials, such as titanium, and the development of sophisticated cooling systems to prevent overheating.

Key Features of the A12 and SR71

Some of the key features of the A-12 and SR-71 include: * High-speed capability: Both aircraft were designed to operate at extremely high speeds, making them difficult to intercept. * High-altitude capability: Both aircraft were designed to operate at extremely high altitudes, making them difficult to detect. * Advanced materials: Both aircraft were made from advanced materials, such as titanium, to reduce weight and increase strength. * Sophisticated cooling systems: Both aircraft had sophisticated cooling systems to prevent overheating during high-speed flight. * Secretive design: Both aircraft were designed to be secretive, with a number of features, such as the use of radar-absorbing materials, to reduce their visibility on radar.

Comparison Table

The following table compares the key features of the A-12 and SR-71:

Aircraft	Top Speed	Altitude	Length	Wingspan
A-12	2,200 mph (3,540 km/h)	80,000 feet (24,400 meters)	101 feet (31 meters)	55 feet (17 meters)
SR-71	2,500 mph (4,020 km/h)	85,000 feet (25,900 meters)	107 feet (33 meters)	55 feet (17 meters)

Legacy of the A12 and SR71

The A-12 and SR-71 are two of the most iconic and secretive aircraft in the history of aviation. Both aircraft played a significant role in the Cold War, providing the United States with a significant advantage in terms of reconnaissance and surveillance. The development of these aircraft also led to a number of advances in technology, including the development of advanced materials and sophisticated cooling systems. Today, the A-12 and SR-71 are remembered as two of the greatest aircraft ever built, and their legacy continues to inspire new generations of engineers and aviation enthusiasts.

The main points of this article can be summarized as follows: the A-12 and SR-71 were two high-speed, high-altitude reconnaissance aircraft developed by Lockheed’s Skunk Works division. The SR-71 was capable of reaching higher speeds and altitudes than the A-12, but both aircraft were significant advancements in aviation technology. The development of these aircraft led to a number of advances in technology and played a significant role in the Cold War.
