The United States is preparing to escalate its military campaign against Iran by deploying a large portion of its most advanced long-range strike weapons, signalling a shift toward a more intense and high-risk phase of the conflict.
According to reports, the US plans to commit a significant share of its inventory of JASSM-ER (Joint Air-to-Surface Standoff Missile–Extended Range), a stealthy cruise missile capable of striking targets from over 600 miles (965 km) away. These weapons are designed to hit heavily defended targets while allowing aircraft to remain at safer distances, reducing exposure to enemy air defences.
This move follows strong rhetoric from Donald Trump, who recently warned of massive strikes on Iran, indicating a more aggressive operational posture. The decision also comes after recent battlefield setbacks, including the reported loss of US aircraft in Iranian airspace, which has challenged claims of complete air superiority.
To support this escalation, missiles are being repositioned from various global stockpiles, including the Pacific region and US-based reserves, to forward-operating locations under US Central Command and bases in the United Kingdom. In addition to the extended-range variant, a large portion of standard JASSM missiles—with a shorter range of around 250 miles—is also being allocated to the conflict.
However, the strategy is placing considerable strain on US military inventories. Reports suggest that over 1,000 JASSM-ER missiles have already been used in the campaign, leaving significantly reduced global reserves. A portion of the remaining stock has also been deemed unusable due to technical issues. Rebuilding these inventories could take years at current production rates, raising concerns about readiness for other potential conflicts.
The reliance on long-range precision weapons reflects a tactical adjustment. Iran has demonstrated that it retains the capability to threaten manned aircraft, reportedly shooting down advanced platforms and targeting drones and helicopters. As a result, the US is increasingly favouring standoff strikes using bombers and cruise missiles to minimise direct risk to personnel.
At the same time, the scale of operations remains substantial. US forces have already conducted thousands of strikes targeting Iranian military infrastructure, including missile systems, naval assets, and defence facilities. The continued use of high-end munitions indicates a prolonged and resource-intensive campaign.
Overall, the repositioning of these advanced missiles suggests that the conflict is entering a more dangerous stage, with heightened intensity, increased resource consumption, and growing strategic implications for both regional stability and global military balance.
