Trump Needs A-10s to Go After Iranian Speedboats and Patrol Ships
The Trump administration has imposed a naval blockade of Iran’s ports, allowing only non‑Iranian vessels to transit the Strait of Hormuz. To counter Iran’s 3,000‑4,000 missile‑armed speedboats and 133 patrol ships, officials argue the A‑10 Thunderbolt II is the most suitable platform, yet only about 30 are currently deployed in the region. The Air Force could reactivate roughly 60 retired A‑10s from the boneyard, potentially tripling the theater fleet to over 90 aircraft. Analysts estimate the blockade could cost Iran up to $13 billion per month, threatening the rial and its economy.
