Janes: Iranian Navy Effectively Destroyed; 4 of 7 Frigates Sunk, Missile Output Drops from 300/Day to 10/Day

Janes satellite imagery analysis confirmed four of Iran's seven Alvand/Jamaran-class frigates sunk or crippled, with CENTCOM reporting over 30 Iranian ships destroyed by March 5. The IRGCN's flagship Soleimani-class catamaran was sunk. US ATACMS and HIMARS were used against naval targets on at least five separate days. Iranian ballistic missile launch capacity dropped from approximately 300 per day at war's start to roughly 10 per day by week two, indicating severe degradation of launch infrastructure.

Analysis
Prior INTSUM (0706) reported CENTCOM claims of 5,000+ targets struck and 'offensive capability down 40%.' Janes' independent satellite verification—4/7 frigates confirmed sunk, missile output collapsed to ~10/day—provides the first authoritative open-source validation of the campaign's destructive effect.
