What is the PrSM missile used by the US in Iran?

The United States has deployed Precision Strike Missiles (PrSMs) for the first time in its ongoing conflict with Iran, as confirmed by US Central Command (CENTCOM). This marks a significant escalation in the war, which has now entered its seventh day with ongoing attacks across the region. PrSMs, developed by Lockheed Martin, can strike targets over 499km away and are intended to enhance US long-range strike capabilities, replacing the Army Tactical Missile Systems currently in use.
