IRIS Neyzeh (P231)

IRIS Neyzeh is a Kaman-class fast attack craft in the Southern Fleet of the Islamic Republic of Iran Navy.

Construction and commissioning
Neyzeh was built by French Constructions Mécaniques de Normandie at Cherbourg, as one of the second six contracted on 14 October 1974. Her keel was laid down on 12 September 1977 and on 5 July 1978, she was launched. Together with IRIS Khanjar and IRIS Tabarzin, Falakhon was delivered in c. 1980, but remained at the shipyard due to an embargo in effect by the French government. France decided to release the three, and all were commissioned into the fleet on 1 August 1981.

Service history
On 1 December 2013, Neyzeh was put into service again after an overhaul that took 30 months. Reportedly, she has been equipped with Gader missiles. In 2014, IRIS Khanjar and Neyzeh were deployed for a joint drill with Pakistan Navy in the Gulf of Oman. Between 2–16 October 2018, she was deployed for an anti-piracy mission to the Arabian Sea and Gulf of Aden, along with her sister IRIS Khanjar and support ship IRIS Bushehr. On the way back home, they made a port call to Karachi and participated in a two-day joint littoral search and rescue drill with Pakistan Navy. She was among Iranian naval vessels participating in the four-day joint wargame in December 2019, with Russian Navy and the People's Liberation Army Navy of China, named 'Marine Security Belt'.
