Key facts

  • Iran’s Islamic Revolutionary Guard Corps (IRGC) said it is preparing to unveil a weapon called the “Father of All Bombs.” (per WION, 8am.media, The Jerusalem Post).
  • IRGC spokesperson Hossein Mohebi said Iran’s missiles had improved in range, destructive power and accuracy (per 8am.media).
  • Mohebi said Iran’s military strategy would focus on asymmetric warfare and that Iran would respond offensively to attacks (per 8am.media, WION).
  • The GBU-43/B weighs around 9,800 kilograms and is one of the largest non-nuclear conventional bombs in the U.S. arsenal (per WION, 8am.media).
  • WION and 8am.media reported that the IRGC announced its planned weapon unveiling on Wednesday, October 21 (per WION, 8am.media).

The brief

Iran’s Islamic Revolutionary Guard Corps says it is preparing to unveil a weapon it calls the “Father of All Bombs,” while describing a military strategy that would emphasize asymmetric warfare and offensive action. IRGC spokesperson Hossein Mohebi made the announcement on Wednesday, October 21, according to WION and 8am.media.

Mohebi also said Iran’s missiles had improved in range, destructive power and accuracy. Those statements describe the IRGC’s claims about its capabilities; the accounts do not independently assess the missile changes or provide supporting measurements. The announcement followed remarks by U.S.

President Donald Trump about the possible use of the GBU-43/B against Iranian nuclear facilities. WION and 8am.media report that Trump raised the possibility on Friday. The Jerusalem Post’s headline characterizes his remarks as a “threat,” while WION and 8am.media describe the possibility of using the bomb without adopting that label.

The GBU-43/B, also called the “Mother of All Bombs,” weighs about 9,800 kilograms, or 21,600 pounds, and is among the largest non-nuclear conventional bombs in the U.S. arsenal, according to WION. 8am.media also gives its weight as approximately 9,800 kilograms and describes it as one of the largest conventional non-nuclear bombs in the U.S. military arsenal.

The names “Father of All Bombs” and “Mother of All Bombs” place Iran’s planned unveiling alongside the U.S. weapon in the public discussion. The sources do not establish that the planned Iranian weapon matches the GBU-43/B in size, function or destructive power, and they provide no technical specifications for Iran’s weapon.

The Jerusalem Post headline links Iran’s announcement to what it calls Trump’s “MOAB threat.” WION and 8am.media likewise connect the announcement with Trump’s comments, but neither excerpt reports details about the circumstances of those remarks.

NDTV Profit’s headline frames the announcement as a warning, and The Times of India headline describes Tehran as threatening with the weapon; those headline characterizations go beyond the direct detail in the excerpts, which report the IRGC’s planned unveiling and Mohebi’s stated strategy.

WION also describes a banner seen in Tehran on September 9, 2026, bearing the words “We will kill Trump” in English and Persian. The excerpt does not identify who put up the banner or connect it to the IRGC’s announcement. The reporting gives no account of the weapon’s development timeline or of a specific next step beyond the planned unveiling.

Why it matters

  • The stated possibility of using the U.S. GBU-43/B against Iranian nuclear facilities and the IRGC’s planned weapon unveiling put military capabilities at the center of the public exchange; the bomb cited in the coverage weighs about 9,800 kilograms.
  • Iran’s population and U.S. personnel or civilians near any future military action could face physical harm, but the reports provide no casualty figures or account of an attack tied to this announcement.
  • The U.S. and Iran express opposing military positions in the coverage: Trump raised possible use of the GBU-43/B against Iranian nuclear facilities, while Mohebi said Iran would emphasize offensive action and asymmetric warfare.

What to watch next

  • Whether the IRGC carries out the announced unveiling of the “Father of All Bombs.”
  • Whether the IRGC provides technical details about the planned weapon.
  • Whether Donald Trump makes a further statement about possible use of the GBU-43/B against Iranian nuclear facilities.
  • Whether Iran’s military puts Mohebi’s stated emphasis on asymmetric warfare and offensive action into practice.
