'Iran Gift'), formerly known as the Arya Rakhsh, was a Japanese-built landing craft used by Iran to lay naval mines during the Iran–Iraq War.

[3] Built in 1978, the 614-ton, 54-meter ship was powered by two diesel engines and featured a bow ramp for unloading cargo.

On 21 September 1987, U.S. forces involved in Operation Prime Chance – the covert part of Operation Earnest Will, the mission to protect U.S.-flagged petroleum-carrying ships in the Persian Gulf – tracked Iran Ajr and dispatched United States Army helicopters from the United States Navy guided-missile frigate USS Jarrett (FFG-33) to shadow her.

[citation needed] A team of United States Navy SEAL commandos later boarded the ship, confirmed the presence of mines, and detained the 26 surviving Iranians.

This evidence of Iranian involvement in the mining of Samuel B. Roberts led to the biggest surface-warfare naval battle since World War II, the retribution campaign of 18 April 1988 called Operation Praying Mantis.
