The Bomb That Ended a War | Summary and Q&A

TL;DR

In Operation Desert Storm, the US military designed and deployed a weapon in less than 4 weeks to destroy deep underground concrete bunkers in Iraq, leading to Saddam Hussein's surrender.

Key Insights

• 🔨 The US Air Force successfully developed and deployed a weapon in just four weeks to destroy underground bunkers in Operation Desert Storm.
• 🌍 Saddam Hussein invaded Kuwait in 1990 to annex it and acquire its oil reserves, leading to a coalition of 35 countries launching air campaigns against Iraq.
• 🧱 Iraqi concrete bunkers, buried 30 to 50 feet underground, were immune to existing bombs designed to penetrate reinforced concrete.
• 💣 The US Air Force and Lockheed Missiles and Space Company worked on a solution, eventually repurposing Army Howitzer barrels to create a heavyweight bomb.
• 🚀 The bomb had to be downsized for delivery using an F-111 fighter, and precision machining was carried out at Watervliet Arsenal.
• ⚙️ The development and manufacturing process involved numerous engineering design changes, with 15 changes estimated to have been made throughout.
• ✈️ The bombs were successfully test dropped and operationalized, with only one test drop necessary before deployment.
• 💥 The GBU-28 bunker buster proved to be highly effective, leading to a hasty ceasefire and potentially contributing to Saddam Hussein's decision to withdraw from Kuwait.

Questions & Answers

Q: How did the US military overcome the challenge of destroying deeply buried concrete bunkers in Operation Desert Storm?

The US military developed the GBU-28 bomb, using Army Howitzer barrels and precision machining techniques to create a heavyweight bomb capable of penetrating the bunkers' concrete structures.

Q: What were the key features of the GBU-28 bomb?

The GBU-28 bomb had a casing made from modified Army Howitzer barrels, a laser-guided head, and stabilizing fins attached to the rear. It was designed to be dropped from high altitudes, using its kinetic energy to penetrate deep into hardened targets.

Q: How did the manufacturing process of the GBU-28 bomb adapt to changing specifications?

The manufacturing process involved multiple engineering design changes, with specifications being phoned in while machining was in progress. The bomb's body was machined from Howitzer barrels, and the nose cone was secured through a heat shrink operation.

Q: How did the GBU-28 bomb prove its effectiveness before operational deployment?

The GBU-28 underwent a test drop in Nevada, burying itself over 100 feet deep. It also successfully punched through a 22-foot thick stack of reinforced concrete slabs during a rocket sled test, confirming its penetration capabilities.

Q: What impact did the GBU-28 bomb have on the Gulf War?

The GBU-28 bomb was used to strike a command and control bunker, leading to smoke pouring out of the bunker's vents and later verified by bomb assessment photos. It is believed that this decisive blow contributed to Saddam Hussein's decision to surrender and marked the end of the Gulf War.

Summary & Key Takeaways

• During Operation Desert Storm, the US Air Force faced the challenge of destroying deeply buried concrete bunkers in Iraq that were immune to conventional bombs.

• A team of US Air Force engineers and Lockheed Missiles and Space Company designed a heavyweight bomb using Army Howitzer barrels to penetrate the bunkers.

• The bomb, called GBU-28, was successfully manufactured in a short timeframe and deployed, leading to the surrender of Saddam Hussein.
