The USS Sirocco recently caught a vessel carrying an illegal weapons cache across the Arabian Sea. The haul? Thousands of Iranian guns en route to Yemen.

In total, sailors walked away with 1,500 AK-47s, 200 rocket-propelled grenade launchers and 20 .50 caliber machine guns. The weapons were probably supposed to arm Iran-backed Shiite insurgents in Yemen. According to a Navy press release, this is the third weapons bust that intercepted Iranian guns bounded for the warring country.

While Iran has capitalized on its illegal capture of stranded American sailors, American sailors allowed the Iranian vessel and crew to depart safely, albeit with no cargo.

Here are some more released photos of all those guns. Enjoy.

160331-N-KL526-362 ARABIAN SEA (March 31, 2016) A cache of weapons is assembled on the deck of the guided-missile destroyer USS Gravely (DDG 107). The weapons were seized from a stateless dhow which was intercepted by the Coastal Patrol ship USS Sirocco (PC 6) on March 28. The illicit cargo included 1,500 AK-47s, 200 RPG launchers, and 21 .50 caliber machine guns. Gravely supported the seizure following the discovery of the weapons by Sirocco’s boarding team. This seizure was the third time in recent weeks international naval forces operating in the waters of the Arabian Sea seized a shipment of illicit arms which the United States assessed originated in Iran and was likely bound for Houthi insurgents in Yemen. The weapons are now in U.S. custody awaiting final disposition. (U.S. Navy Photo/Released)
