"Sahand" is armed with cruise anti-ship missiles and has a helicopter deck and electronic warfare systems.
"Sahand" was said to have twice the defensive and offensive power of , with upgraded torpedo tubes, various types of anti-air and anti-surface weapons, surface-to-air and surface-to-surface missiles, and a point-defense system. "Sahand" is equipped with an anti-submarine system and a stealth system, and enjoys higher maneuverability and increased operational range. The ship has four powerful engines, an improvement on "Jamaran".
"Sahand" was capable of sailing on turbulent waters and distant oceans for 150 days while accompanied by a support vessel.
Irani also said that Nawab, a domestically-developed medium-range surface-to-air missile system, was installed on the Sahand destroyer. Point-defense weapon systems for detecting and destroying incoming missiles and enemy aircraft and anti-missile systems have also been used in the indigenous destroyer. He also added that efforts were underway to install Abu Mahdi naval cruise missile on Iranian military watercraft, noting that the country’s destroyers would be equipped with more powerful cruise missiles. He explained that the Iranian Navy’s surface-to-surface cruise missile power had doubled and that the country’s destroyers will be deployed to high sea for the first time with 8 cruise missiles mounted on them.
History.
"Sahand" was unveiled to the public in late November 2012. All that was shown was pictures of the completed hull and superstructure. The ship was not outfitted with weapons, electronics, or other essential military equipment. These systems were due to be installed in one or two years. The ship entered service on 1 December 2018. "Sahand" is named in the memory of the original "Sahand" that was sunk by the U.S. in Operation Praying Mantis during the Iran–Iraq War on 18 April 1988.
In June 2021, "Sahand", accompanied by IRINS "Makran" (a naval-converted oil tanker), were the first Iranian naval ships to reach the Atlantic without docking in an international port, according to official Iranian sources. Early media report incorrectly suggested they were bound for Venezuela, but the ships were bound for Saint Petersburg to attend Navy Day to commemorate the 325th anniversary of the Russian Navy foundation. "Makran" was reported to be carrying several Fast Attack Craft. 
Sinking, Salvage &amp; Restoration.
On 7 July 2024, "Sahand" capsized during repairs in Bandar Abbas, reportedly due to a technical fault. Several people were hospitalized from the incident, and part of the ship became submerged. Immediately after the capsizing, the head of Iran Shipbuilding &amp; Offshore Industries Complex (ISOICO) said "there was still a possibility" of repairing the ship and restoring it to operation. Later on 9 July the ship entirely sank after the rope holding the capsized ship broke. Reportedly salvaged on 13 July, but also reportedly sank again on an even keel in slightly deeper water. On 22 July 2024, the ISOICO led salvage operation was successful and "Sahand" was finally pulled out of water completely. Iran Navy said the sinking incident was due to the ship losing its balance due to water ingress while undergoing repairs at the wharf. Reports say additional fitments like SAMs might have affected the ship's stability. The ship has now been towed for repairs at same port of Bandar Abbas, where restoration work will be carried out. However, the volume of damage and the estimated time needed for completing the restoration of the ship has not been disclosed.
