The Jerusalem Post reports: “Two Iranian ships carrying a chemical ingredient crucial for missile propellant will sail from China to Iran within the next few weeks, security sources from two Western countries with knowledge of the matter told the Financial Times. 

The Iranian cargo vessels – the Golbon and the Jairan – will reportedly carry more than 1,000 tons of sodium perchlorate, a key ingredient to make the missile propellant ammonium perchlorate. 

The officials said the sodium perchlorate on the ships could produce up to 960 tons of ammonium perchlorate, which is enough to fuel 260 mid-range Iranian missiles. 

Ammonium perchlorate makes up approximately 70% of propellant for solid-fuel missiles…”
