Iran's state TV says the country's powerful Revolutionary Guard has received its first three squadrons of radar-evading flying boats which were developed to collect intelligence and perform attack missions.
The plane was unveiled on the last day of the Islamic Republic's Sacred Defense Week marking the Iran-Iraq War.
Iranian Defense Minister Ahmad Wahidi said the new development improves Iran's aerial and naval capabilities.
"Arming the navy with advanced weapons boosts stability and security in the region and increases the Islamic Republic's deterrent power," Wahidi said.
The development comes after Iran in 2009 said it had successfully tested the domestically made craft. A flying boat is a fixed-winged seaplane with a hull that allows it to land on water.
It's part of Tehran's efforts to boost its arsenal and military capabilities despite international sanctions over the country's controversial nuclear program.
Iran's military achievements cannot be independently verified.
The state TV broadcast footage of the craft in operation in the air and sea. Tuesday's report says the plane - dubbed Bavar-2 or Confidence-2 - can be used for surveillance. It can also carry guns and transmit data.
