"The Bayandor Destroyer will join the naval fleet on May 24 after undergoing major repair work and being equipped with various weapons systems," Sayyari told reporters on Thursday.
He said that Iran can use the destroyer to carry out missions in international waters in the future.
Sayyari said the destroyer is fitted with state-of-the-art equipment such as missile, torpedo, artillery, sonar and other information and communication systems.
In recent years, Iran has made great achievements in its defense sector and attained self-sufficiency in producing essential military equipment and systems.
Iran's first home-made destroyer, Jamaran, was launched in late February 2010. The Mowdge Class vessel has a displacement of around 14,000 tons and is equipped with modern radars and electronic warfare capabilities and is armed with a variety of anti-ship, surface-to-surface and surface-to-air missiles.
Iranian defense ministry officials had said earlier that the third generation of the home-made vessel, Jamaran-3 destroyer, will come into operation by the end of the current Iranian year (March 21, 2013 - March 20, 2014).
