Overview
- Reporting on Oct. 15–16 shows Pentagon planners drew up additional strike packages that explicitly list the GBU-43/B Massive Ordnance Air Blast (MOAB) as a possible munition against Iranian targets.
- The options identify targets such as energy infrastructure and the suspected underground site known as Pickaxe Mountain but inclusion in plans does not mean the president has authorized a strike.
- Military and technical experts noted the MOAB detonates above ground to produce a wide blast and is not designed to penetrate thick rock, so it is unlikely to destroy deeply buried facilities that require bunker‑busting warheads.
- Officials and analysts warned the bomb’s large blast radius could cause civilian casualties and prompt Iranian retaliation, and some internal planning documents frame options as a symbolic “fireworks show” timed before withdrawal.
- The MOAB was used once in 2017; planners continue to weigh alternatives such as deeper‑penetrating munitions and to balance political pressure around the midterm elections with the risks of escalation.
