US Concerned Iran Is Deploying Advanced Anti-Ship Ballistic Missiles
Washington fears Iran is deploying Qassem Basir and Khalij Fars missiles with advanced electro-optical guidance to target US warships, potentially aided by foreign intelligence.
Washington is increasingly concerned that Iran may have begun deploying advanced anti-ship ballistic missiles equipped with sophisticated electro-optical guidance systems, raising the stakes in ongoing regional hostilities. According to US intelligence assessments and recent reports, the primary weapons causing alarm are the Qassem Basir and the Khalij Fars. US officials fear that Tehran is attempting to inflict severe damage on American naval assets in the Middle East as the severe economic sanctions take a heavy toll on the Iranian economy.
Advanced Guidance Systems and Moving Targets
At the center of US apprehension are two distinct missiles with shared technological traits: the Qassem Basir, a relatively new medium-range ballistic missile, and the Khalij Fars, an established anti-ship ballistic missile. Both systems feature electro-optical and infrared terminal guidance systems designed to locate and track moving targets in flight. While stationary ground targets rely purely on pre-programmed coordinates, naval vessels constantly maneuver, making terminal guidance critical for precision strikes.
While definitive proof of active combat deployment against US warships remains under review, recent waves of attacks in the Persian Gulf and surrounding waters have heightened military alert levels. Analysts note that Iran views military escalation and potential disruption as preferable to enduring the suffocating US-led economic blockade indefinitely, seeking to challenge Washington before upcoming political milestones.
Technical Profile of the Qassem Basir and Khalij Fars
Unveiled in May 2025 and named after slain Islamic Revolutionary Guard Corps Quds Force commander Qasem Soleimani, the Qassem Basir is a two-stage solid-fuel ballistic missile. It boasts an estimated range of 1,200 kilometers and a warhead weighing approximately 500 kilograms. Iranian state media claims the missile is resistant to electronic warfare, bypasses traditional GPS reliance through optical tracking, and features a maneuverable warhead during atmospheric re-entry.
The Khalij Fars, deployed since 2014 and derived from the Fateh-110 family, represents an older but proven maritime strike platform. With a range of roughly 300 kilometers, a 650-kilogram warhead, and solid-propellant propulsion, it achieves speeds up to three times the speed of sound, covering its maximum distance in under five minutes using inertial and terminal electro-optical navigation.
Intelligence Sharing and Strategic Concerns
«The primary American concern extends beyond missile accuracy to Iran's ability to locate vessels far out at sea in the first place.»
Even the most advanced electro-optical seeker requires precise pre-launch targeting data to approach a moving warship. US military officials emphasize that recent airstrikes and naval engagements in the Strait of Hormuz were intended to systematically dismantle Iran's long-range radar, surveillance, and observation infrastructure.
Intelligence reports suggest that Beijing and Moscow may be covertly assisting Tehran by supplying critical satellite imagery and tracking data. Although President Donald Trump has previously downplayed the direct impact of foreign intelligence cooperation, the US Treasury Department imposed sanctions in May on Chinese entities accused of funneling reconnaissance data to Iran, underscoring the delicate balance of modern maritime deterrence.
