Introduction: A Misguided Inquiry

Before delving into the comparison between the SR-71 Blackbird and the A-12 Oxcart, it's essential to acknowledge that the question of which is better can be complex and multifaceted. Some define 'better' through operational success, while others might consider raw performance metrics. However, it's curious to note that the comparison requested involves an aircraft that saw extensive operational use and one that never made it past the test phase. This perspective highlights a level of ignorance in air force history.

Visual Evidence and Irony

The selected images for comparison—an A-12 Oxcart in USAF markings and an SR-71 Blackbird in NASA markings from the 1990s—underscores the irony of the inquiry. The A-12, while impressive, never left the test phase, whereas the SR-71 served with distinction for decades. This juxtaposition adds an interesting dimension to the narrative.

Performance Specifications

When evaluating performance, we often refer to key metrics like top speed and maximum altitude. In this case, there's a striking similarity between the two aircraft:

Top Speed: A-12 Mach 3.3; SR-71 Mach 3.3 Maximum Altitude: A-12 85,000 ft (26,000 m) or higher; SR-71 85,000 ft (26,000 m) Ferry Range with Inflight Refueling: A-12 2,500 nautical miles (2,900 miles, 4,600 km); SR-71 2,824 nautical miles (3,250 miles, 5,230 km)

It's worth noting that some sources report the A-12 as being slightly faster and with a slightly higher maximum altitude. Nevertheless, these differences are minimal and don't significantly alter the overall picture of the two aircraft's capabilities.

A-12 vs. SR-71 Outside of Specifications

The A-12 initially had the edge with its superior camera placement, which was housed in a bay behind the pilot. This setup translated into better initial imaging capabilities. However, improvements in the SR-71's camera systems over time negated the A-12's advantage in this area.

Moreover, the SR-71 was equipped with a variety of advanced systems, including:

Optical and Infrared Imagery Systems Side-Looking Airborne Radar (SLAR) Electronic Intelligence (ELINT) Gathering Systems Defensive Systems for Countering Missiles and Airborne Fighters Recorder Systems for SLAR, ELINT, and Maintenance Data more...

The inclusion of these systems makes the SR-71 vastly more versatile and capable for a wide range of missions, which is a significant advantage over the A-12.

Operational Success and Legacy

The SR-71's operational record speaks for itself. It set world records and operated for decades, making it not just a technological marvel but a reliable and proven asset in military service. Notably, on July 28, 1976, SR-71 serial number 61-7962, piloted by then-Captain Robert Helt, broke the world record for speed in a controlled configuration.

Additionally, the SR-71 Blackbird made its mark through its impressive cockpit design, which, while decidedly 1960s in style, was cutting-edge for its time. This legacy is further underscored by memorable experiences, such as the author witnessing a SR-71 land at Kadena Air Base in 1986.

When comparing the SR-71 and A-12, it becomes clear that while the A-12's performance metrics might edge ahead in certain aspects, the SR-71's operational capabilities, enhanced systems, and enduring legacy make it a more superior aircraft in a broader operational context.
