What technology was highlighted during Operation Linebacker?

During Operation Linebacker, which was a significant aerial bombing campaign conducted by the United States during the Vietnam War in 1972, precision-guided munitions were notably emphasized. These advanced munitions represented a significant evolution in military technology as they allowed for more accurate targeting compared to traditional unguided bombs. The implementation of these munitions aimed to enhance effectiveness while minimizing collateral damage, which was a critical objective for U.S. military operations at the time.

Precision-guided munitions, often referred to as "smart bombs," utilized guidance systems such as laser targeting and inertial navigation to hit specific targets with greater accuracy. Their introduction during Operation Linebacker marked a shift in air combat tactics, showcasing how technology could effectively change the dynamics of warfare.

The other options, while relevant to military operations generally, did not play a central role in this specific campaign. For instance, stealth bombers and drone warfare were not yet integral parts of military operations at that time, and nuclear options were not the focus of this particular campaign, which aimed to achieve strategic bombardment without escalating to nuclear warfare.
