Sensors
- All radars are controlled by Washi I-Commander fire control system merging together data from multiple sensors and displaying it on screens of relevant officers.
- Situational awareness is provided by Type 515 radar. Designed to be the primary radar aboard small vessels, Type 515 is a solid state 3D AESA radar composed of four antennas, each facing a different direction. Both multi-beam and pulse-doppler techniques are employed during the operation. It is highly resistant to ECM. The radar operates on S-band (IEEE), which compled with advanced signal forming techniques makes it efficient at detecting low-RCS targets. Maximum detection range is 250 kilometres for high flying targets, and 25km for low flying cruise missiles. Up to 300 targets can be tracked at once. Type 515 provides support to fire control, being capable of detecting splashes and guiding anti-air missiles.
- 3x Type 115 Model 4 Fire Control Radar is a fire control radar operating in I and J bands. This radar provides continuous illumination for weapon system it is linked to. It is capable of illuminating a target up to 300km away against a high flying target.
- 2x Type 111 navigation radar operating in E, F and I bands.
- Washi Wa-18 Electro optical system contains an integrated EU, IR, laser rangefinder and designator all combined to be able to be operated by a single operator. The system is capable of operating automatically, intelligently auto-adjusts for threat evaluation and weapons adjustment. It is capable of spotting targets at maximum range of 50km and designating targets via laser at 8km.
- Type 71 bow mounted sonar is a active - passive sonar system mounted inside the bow. The system provides automatic detection and tracking of both surface and submerged targets. Maximum detection range is 35 kilometres.
- Type 50 anti-saboteur sonar is a lightweight sonar designed to detect asymmetric threats. It can detect a swimmer at 300 meters, swimmer with delivery vehicle at 400 m with resolution up to 5 meters.
- Type 80 Towed Array Sonar is a long cable full of microphones towed behind the ship. It is capable of detecting targets 120km away.
Countermeasures
- Washi A-16 is a mortar-style countermeasures launcher designed to launch decoy and chaff. It is composed of 6 130mm mortar tubes in parallel rows. Each launcher holds from 12 to 36 rounds, depending on type and size. Two sets in total have been installed.
Current ammunition option include:
* V21 Active Aecoy Round
* V18 Floating Decoy
* V71 Chaff Round
* V19 TALOS Flare
- Type 132 ECM suite is a ECM suite for light warships. It is designed to intercept emissions of airborne and shipborne tar-get acquisition radars, weapons control radars and anti-ship missile radar seekers. The system automatically tracks and classifies the detected emissions and is capable of covering spectrum from 2 GHz to 18 GHz. Maximum detection range is 900km. It's composition are several ESM antennas and a laser warning receiver.
- 1x Type 113 CIWS is a close in weapons system built around seven barrel 31x167mm gattling gun. The gun is gas operated allowing it theoretical rate of fire of 6 000 rounds per minute, but can be programmed to fire in 1 000, 2 000 or 4 000 rpm mode. Maximum firing range is 5 kilometres. Each CIWS contains two ammunition boxes with 1200 rounds. The system has it's own fire control radar capable of engaging targets up to 15km away as well as an electro-optical system with a laser rangefinder.
- Washi T-16 is a towed anti-torpedo countermeasure. The towed system contains acoustics projector connected to the warship via a cable. The system detects the torpedo's ping frequency and amplifies it 2-3 times, aiming to lure the weapon away from the ship.
Armaments
- The ship is equipped with 24x "Kin" VLS cells, 16 at the bow, 8 mid-ship.
First introduced in 2001, "Kin" VLS system comes in four variants. There is Kin-3, frontal VLS tubes are of, and Kin-4 for the mid-ship tubes - the versions differ on length of missile accepted. The system comes in 8 - cell modules, each module weighting 12 tons and having cells of 56 x 56 cm diameter. A hot launch method is used with exhaust gases being released via uptake hatch. Up to eight missiles can be launched within 10 seconds. Kin-3 is capable of accepting missiles up to 5 meters in length. For Kin-4, that length increases to 7 meters.
- Six "Tsurihito" lightweight torpedoes have been installed. Tsurihito is a 325mm torpedo weighting 300 kilograms with length of 2.9 meters. It is capable of engaging targets from 10 to 25 km away depending on speed, and targetting submerged objects up to one kilometer underwater. It is powered by an electric pump jet, and capable of "silent" running. Responsible for destroying the enemy is 35 kilograms shaped charge warhead designed to penetrate titanium/double hulls of communist submarines. Maximum speed is 50 knots. Target is acquired via active / passive acoustinc hoping. Advanced electronics allow discrimination below actual and perceived threats, decoys and f anechoic coatings. On client's demand another model of torpedo can be installed.
- The corvette is fitted with a single Arakawa Type 1986 78mm naval gun. First fielded in 1986, Type 1986 is intended to counter both surface and air targets; it fires 78x640mm rounds and is famed for it's high rate of fire - 110 rounds per minute. The design is split in both over-deck and below-deck elements; the turret is made from composites and fully unmanned, thus reducing size and allowing placement on even smallest ships. The crew is composed of a gunner and three loaders. Below the deck is located a magazine housing 80 rounds in two rows; loading can be done even during firing. The rounds are stored vertically. The ammunition weights around 12 kilograms. HE, HE-FRAG, HE-AP and HE-SAPOMER rounds are available. 400 rounds are carried.
- Two 13.2 mm HMGs are installed. Type 1960 is a gas operated heavy machine gun capable of shooting 700 rounds per minute up to 2000 meters.
- Four general purpose machine guns located all over the ship.
- One hangar for medium sized ASW helicopters at the stern.
