PNS Azmat is the lead ship of the Azmat-class missile boats of the Pakistan Navy based on the Chinese design Type 037II Houjian-class.

[1] Azmat was commissioned on 24 April 2012 at Tianjin, China[2][3] after being launched on 20 September 2011.

PNS Azmat FAC(M) is a green water vessel and does not have blue water capabilities, and so it is mostly used to patrol the coast, and to assist the Coast Guard in any special operations that require extensive firepower.

The vessel uses a fully automatic 23 mm gun.

The decision to install the 23 mm gun was due to lack of hull space, which meant less storage area for 75-100 mm rounds required for larger guns and weight requirements.
