F22P Zulfiquar Class Frigate
The F-22P or Sword class frigate is a 2,500t multi-mission, conventionally powered frigate built for the Pakistan Navy. Design and construction of the F-22P started after a $750m deal was signed in 2005 between Pakistan's Ministry of Defence Production (MoDP) and China Shipbuilding Trading Co (CSTC).
The deal involved an order for construction of four F-22P frigates for the Pakistan Navy's fleet. The deal included an order for four to six Harbin Z-9EC helicopters and ammunition for the frigates. The first of the frigates, PNS Zulifqar, was delivered in September 2009.
At basics, it is an updated model of the type 053H3 or Jiangwei-class frigate built by China since the 1990s. The F-22P's hull contains China's type 054 frigate's radar cross-section reduction, which helps prevent detection by radars mounted on other ships, aircraft and anti-ship missiles.
The frigates can operate in multi-threat environments and are equipped with long-range surface-to-surface and surface-to-air missiles, which are capable of attacking multiple targets simultaneously. They are also equipped with under-sea sensors that can detect nuclear and conventional submarines at long range. Powered by four main diesel engines, the F-22P frigate can accommodate about 200 personnel.
The frigates have long-range sensors, navigational radars and trackers, sonars, electronic warfare systems, counter measures (ESM/ECM) systems and advanced command and control systems.
Powered by its four main diesel engines, the F-22P frigate can accommodate about 200 personnel.
Armaments :
F-22P frigates are equipped with a single 76.2mm main gun, eight C-802/CSS-N-8 anti-ship missiles, an eight-round FM-90 surface-to-air missile (SAM) and two hangar-top type 730B 30mm close-in weapon system (CIWS) units. They also feature RDC-32 anti-submarine rockets, two triple ET-52C torpedo tubes, state-of-the-art homing weapon systems and depth charges. ET-52C is the Chinese development of the Italian Alenia A244-S light ASW acoustic homing torpedo, and is considered by many domestic Chinese sources as Chinese equivalent of the A244-S Mod. 2 version. ET52 is essentially the A244-S torpedo with technologies of US Mk 46 Mod.
The main gun was developed in China and is based on the Russian AK-176M. The Chinese variant contains a redesigned stealth turret to reduce radar cross-section. The gun can engage other ships and aircraft and defend against anti-ship missiles.
The anti-ship C-802 subsonic surface-to-surface missiles are carried in two containers with four cells each, installed between the main deck and the hangar. The two containers can also carry CY series anti-submarine rockets and be loaded with anti-ship and anti-submarine weapons. It is an improved version of the C-801 which employs a small turbojet engine in place of the original solid rocket engine. The weight of the subsonic (0.9 Mach) Yingji-802 is reduced from 815 kilograms to 715 kilograms, but its range is increased from 42 kilometers to 120 kilometers. The 165 kg. (363 lb.) warhead is just as powerful as the earlier version. Since the missile has a small radar reflectivity and is only about five to seven meters above the sea surface when it attacks the target, and since its guidance equipment has strong anti-jamming capability, target ships have a very low success rate in intercepting the missile. The hit probability of the Yingji-802 is estimated to be as high as 98 percent. The Yingji-802 can be launched from airplanes, ships, submarines and land-based vehicles, and is considered along with the US "Harpoon" as among the best anti-ship missiles of the present-day world.
The FM-90N SAM system is installed between the main deck and main gun. The system has eight cells containing one missile each. The system is set up on a mount that can be lifted in the direction of the threat. The FM-90N can engage different targets by using different guidance modes. These targets can even include supersonic and sub-sonic sea-skimming missiles. The system is also designed to engage small targets such as unmanned aerial vehicles (UAV). FM90 has Command + Electro-Optical Tracking guidance system and can engage targets with mach 2.3 at range of 15 km and altitude of 6 km.
The 730B CIWS is fitted on the aircraft hangar and contains two seven-barrel Gatling guns of 30mm calibre. The CIWS employs type 347G radar and an OFC-3 electro-optic director. It can also be equipped with the FL-3000N fire-and-forget missile system by fitting up to two single-round FL-3000N launchers on each CIWS gun mount.
Ada Class Corvette
The general characteristics of the class is a displacement of approximately 2,300tons at full load, length of 99.5m, beam of 14.4m, maximum speed of +29 knots and a range of 3,500n.m. with the cruising speed of 15 knots. The crew is only 93 people while there is accommodation for 106 passengers including flying crew and technicians (11 people). The propulsion is combined diesel and gas (CODAG) propulsion system, which consists of a gas-turbine and two diesel engines delivering a power of around 30,000kW. The ships carry one medium helicopter (S-70 Seahawk) which can be accommodated in a hangar. Additionally, each corvette carries two rigid-hulled inflatable boats (RHIB). The ships feature a steel hull and fragmentation resistant composite superstructure. Fore and aft masts and the funnel have been constructed with sea resistant aluminum alloys. The warships of the MILGEM project are designed to fully operate at sea state 5 and partially operate at sea state 6. Reduction and management of the ship signatures was taken as the major input during the whole design phase. Many classified precautions were taken in order to reduce hydrodynamic, acoustic, magnetic signature, Infrared Signature (IR), Radar Cross Section (RCS), and therefore, to achieve the specified level of stealth feature. Collective Protection Zones are designed to ensure the ships ability under NBC conditions. Locally designed degaussing system minimizes the magnetic signature for protection against the magnetic mines. The design focused on reduced Life Cycle Cost while the configuration is easily adaptable to technological improvements and changes due to operational requirements.
Armaments :
Each ship of the class is equipped with a fully automatic OTO Melara Super Rapid main gun of 76mm/62cal fitted with a stealth cupola and located on the bow deck. The gun is capable to intercept air and surface targets at a distance of 16 km (the effective range is between 5 and 8km) unleashing 120 rounds per minute weighting greater than 6 kg each.
Except the main gun, for the purpose of asymmetric warfare and coastal defense, the corvettes are equipped with two Aselsan Stabilized Machine Gun Platform (STAMP) with 12.7mm heavy machine guns. STAMP incorporate advanced features, such as remote operation, built-in electro-optic sensor system, day and night operation, automatic target tracking (detect, track and fire on the move) stabilized turret and ballistic computation. The infrared and daylight TV cameras of the system enable detection and recognition of targets that would not be possible with naked eye. The system is capable of ballistic calculation and automatically tracking the targets and enabling a high hit probability by accurate firings. STAMP System has a stabilized turret which enables the line-of-sight of the gun to be aimed at the target at all times.
For specialized anti-aircraft and anti-missile defense (CIWS), the vessels of the class have one Mk 49 Guided Missile Launching System (GMLS) with 21 missiles each ready to launch RIM 116 Rolling Airframe Missile (RAM). The launching system is located atop the helicopter hangar. Together, missiles and launching system comprise the RAM Mk 31 Guided Missile Weapon System (GMWS). RAM is a class-leading weapon system providing a full perimeter protection to the vessel operator. The Block 1A missile has infrared guidance system that enables it to intercept missiles that are not emitting any radar signals while the Block 0 passive radar homing capabilities have been retained. The range exceeds the 9 km and the speed surpasses the 2 Mach.
Each corvette is equipped with eight Boeing RGM -84L Harpoon anti-ship missiles in two Mk141 quad launchers amidships. Turkey is one of the few countries in the region (and perhaps the only one) that have this advanced variant (Harpoon Block II missiles are designated -L-) in their military inventory. Harpoon Block II offers an expanded engagement envelope, enhanced resistance to electronic countermeasures and improved targeting.
For Anti-Submarine Warfare (ASW) the ships are equipped with two twin Mk32 (Mod 9?) 324mm torpedo launchers in fixed positions for Honeywell Mk46 Mod 5 or Mk54 active or passive/active acoustic homing lightweight torpedoes. The Mk46 torpedoes have a range of approximately 8,500-11,000m at 45 knots (maximum speed) and they carry a very powerful warhead of 44.5kg for this category of lightweight torpedoes. They are designed to attack fast submarines and to engage them even over 400m below sea level as well as surface targets (latest variants such as Mod 5). The Mk54 torpedo is the next generation of Mk46 torpedo as it combines the expensive Mk50 search and homing system with the propulsion system of the Mk46 torpedo for optimized performance in the most challenging littoral scenarios. It has a speed over than 40 knots and it carries the same warhead as the Mk46.
The corvettes of the class are equipped with the British Ultra Electronics Sea Sentor Surface Ship Torpedo Defence (SSTD) system. The system consists of an acoustic passive towed array, a towed acoustic countermeasure, a single-drum winch, a processing cabinet, two display consoles, two expendable acoustic device/countermeasures launchers (port and starboard) and 16 expendable acoustic devices (8 in each launcher). The passive acoustic towed array is specifically designed to detect torpedoes and has additional in-built non-acoustic as well as acoustic intercept sensors.
General Comparison of Salient features
I just arranged general information in a comparison with bit graphical modification so improvements are welcome, particularly regarding radars and sensors of F22P.
