F-22P Zulfiquar Class Frigate - Design

Design

The F-22P hull uses many of the radar cross-section reduction features of China's Type 054 frigate to help it evade detection by radars mounted on other ships, aircraft and anti-ship missiles.

The 76.2 mm calibre main gun is a Chinese development of the Russian AK-176M, the main difference being that the Chinese variant adopts a re-designed stealthy turret to reduce radar cross-section. The gun is designed to engage ships, aircraft and anti-ship missiles. In front of the main gun are two 6-cell RDC-32 anti-submarine rocket launchers.

The frigate's primary surface-to-surface missile armament comprises eight C-802 subsonic anti-ship missiles carried in two launchers with four cells each, fitted between the foremast and the funnel. These containers are also compatible with the CY series anti-submarine rockets and may be loaded with a combination of anti-ship and anti-submarine weapons.

The FM-90N surface-to-air missile (SAM) system is fitted between the main deck and main gun. The launcher has eight cells each containing one missile and is fitted on a mount that can be elevated and traversed in the direction of the threat. The FM-90N can engage several targets, including supersonic and sub-sonic sea-skimming missiles, using different guidance modes simultaneously. The system is also designed to engage small targets such as unmanned aerial vehicles (UAV). However, the FM-90 has limited engagement angles as compared to a SAM fired from a vertical launch system. Also, the FM-90 has inferior range,and is also non-reloadable, hence it is not suited for blue water patrol

A close-in weapon system (CIWS), the Type 730B, is mounted on the aircraft hangar. Comprising two seven-barrel gatling guns of 30 mm calibre, the F-22P is believed to be the first ship armed with the Type 730B, which uses off-mount sensors such as the Type 347G radar and the OFC-3 electro-optic director. The guns are mounted side-by-side on the aircraft hangar, with the off-mount sensors in between. The CIWS can be upgraded with the FL-3000N fire-and-forget missile system by installing up to two single-round FL-3000N launchers on each existing CIWS gun mount.

The Harbin Z-9EC anti-submarine warfare (ASW) helicopter is equipped with a surface-search radar, low frequency dipping sonar, radar warning receiver, doppler navigation system and armed with torpedoes. The helicopter can be armed with one torpedo on the starboard side. A small antenna on the roof may provide a data-link, allowing the Z-9 to act as a relay for targeting data between the ship and long range anti-ship missiles such as the C-802.
