Last Updated: November 30, 2025, 06:29 IST America wants its unexploded GBU-39B smart bomb found in Lebanon immediately back. Washington fears that if this bomb reaches Iran, it will copy its technology through reverse engineering. Iran has already similarly recreated US and Israeli drones. America’s unexploded bomb has now become a headache. America is worried about one of its bombs. A bomb that didn’t explode and now the risk of it falling into the wrong hands has increased. A US GBU-39B Small Diameter Bomb (SDB) failed to explode during an Israeli attack on Hezbollah-held areas of Lebanon and was reportedly found completely safe. This is what scares America, because if this bomb falls into the hands of Iran, then there is a possibility of copying it through reverse engineering. This bomb falling into the hands of the enemy is nothing less than a headache for America. Can Iran reverse engineer? If anyone thinks that Iran will not be able to understand such high-tech American technology, then he is wrong. June reports show that when Israel attacked Iran with ‘Hermes’ and FPV drones, many of those drones were not destroyed. Iran picked them up and reverse engineered them into similar drones, and in many cases even better ones. Iran has already created its own stealth drone line by copying the US RQ-170 stealth drone. That is, if this GBU-39B bomb reaches Iran, it can prepare a similar smart, long-range, GPS-guided munition by understanding its blueprint. What did America do about GBU-39B? According to media reports, America immediately contacted the Lebanese government and demanded that this unexploded bomb be returned. Washington’s fear is not only that these munitions will reach Iran, but also that any of Iran, China or Russia could copy them through reverse engineering. Lebanese reports said the GBU-39B was part of an Israeli strike targeting the Hezbollah stronghold of Harat Harak. Not one bomb exploded and the entire system including guidance unit, GPS module, electronics were found intact. What is the power of GBU-39B bomb? This bomb is small, weighs 113 kg, but the technology is very advanced. It has a guidance system that is not affected by weather or smoke and can hit targets with great accuracy up to 40 nautical miles away. America does not want to allow this technology to reach Iran or its allies under any circumstances. America’s concern is clear, if Iran gets this bomb, then it can open it and understand the engineering of each part and then increase its missile and drone capability distribution. And this ability of Iran is not a guess, but has been proven many times. The Lebanese government has not yet clarified whether it has the bomb or not, and how it will deal with America’s request.
