US Deploys Suicide Unmanned Surface Vessels in Iran Strike, Shifting Naval Warfare

The US military recently conducted its first-ever operational use of suicide unmanned surface vessels (USVs), known as Corsair, in a strike against an Iranian naval base in Bandar Abbas. The attack, carried out between Sunday and Monday, targeted an Iranian Ghadir-class submarine and maintenance facilities, destroying them with precision and causing a massive explosion. The Corsair USV is a 7.3-meter-long unmanned boat capable of carrying 450 kilograms of explosives over distances exceeding 1,000 nautical miles. It is operated by Task Force 59, a US Navy experimental unit that integrates artificial intelligence into daily operations.

Unmanned surface vessels (USVs) are remotely controlled or autonomous boats used for various military purposes, including reconnaissance, mine detection, rescue, and offensive suicide missions. The US leads Western powers in developing large USVs for long-range surveillance and attack, while Ukraine has pioneered extensive use of low-cost, fast suicide USVs to disrupt the Russian Black Sea fleet. Iran and its proxies, such as the Houthi rebels in Yemen, also deploy armed suicide USVs to threaten commercial shipping and military targets.

USVs offer significant advantages including reduced risk to human life, lower costs compared to traditional warships, stealth capabilities due to their small size and low radar signature, and the ability to enable asymmetric warfare. These vessels allow smaller or less powerful forces to challenge major naval powers effectively.

For Israel, maritime security is critical as over 90% of its trade passes through sea routes. The Israeli Navy has been an early adopter of USVs, primarily for defensive purposes such as patrolling coastal borders and protecting strategic gas platforms using vessels like Rafael's Protector. However, Israel faces threats from Iranian-supplied USVs used by Hezbollah and the Houthis, necessitating continuous upgrades to detection and weapon systems on its new Saar 6 corvettes.

This development marks a transformative moment in naval warfare, highlighting the growing role of autonomous and remotely operated vessels in modern conflicts and the evolving nature of maritime security challenges worldwide.
