The design has been directed to minimizing the optical and infrared signature, above water acoustic and hydro acoustic signature, underwater electrical potential and magnetic signature, pressure signature, radar cross section and actively emitted signals. The hull material is a sandwich construction comprising a PVC core with a carbon fiber and vinyl laminate. The material provides high strength and rigidity, low weight, good shock resistance, low radar and magnetic signature.
It is ideally suited for recon and scouting, and works well alone or grouped with more conventional ships. When traveling with a fleet, the 205 Ymekydun is often found on the fleet’s outer perimeter scouring the waters for mines and submarines.
For its main gun, the 205 Ymekydun uses the versatile HIA 24c autocannon, which is mounted on its bow in a stealth cupola. The HIA 24c utilizes a 57 mm x 76 caliber round, and is even capable of firing smart munitions. For increased accuracy, a small radar is mounted on the gun’s barrel, which measures muzzle velocity for fire control purposes. The gun’s accuracy, range, and 220 rounds per minute rate of fire make it valuable as an artillery piece, AA gun, or CIWS.
(Older vessels had a dual barrel rotation arrangement that featured both a 57 mm gun and a 76 mm gun. This system was later replaced.)
To supplement its main gun, the 205 Ymekydun is equipped with numerous torpedo tubes and missile launchers. For reasons of stealth, these weapons are stowed below deck, and are fired through hatches on the sides of the ship.
The ship features an integrated Fire Control and Friend or Foe Identification System (FCFFIS). This tool collects the ship's sensor data, and is capable of using that information to manage the ship’s weapons and decoys. With the processing power and information available to it; this system is capable of tracking, prioritizing, and eliminating threats with efficiency.
Managed Defensive Systems R4 Surface to Air Missiles - R4's are able to engage enemy aircraft and missiles at a range of 50 km. They are designed to destroy hypersonic anti-ship missiles, and excel in that role. Given the missile options available to the 205 Ymekydun, it carries between 0 and 64 R4's. HIA 24c Autocannon – Given the gun’s range and high rate of fire, it is perfectly capable of serving as the ship’s CIWS. As such, the ship’s FCFFIS system can be programmed to integrate the HIA 24c into its automated aircraft and missile defenses if desired. ESM/ECM: VCI Avitronics SME 100/200 ESM & ELINT Decoys: 2x 48 VCI Avitronics MRL (96 decoys)
Specifcations Crew: 43 Cargo: 2,000 tons of nonessential equipment and supplies. Each enlisted crew member has a small locker for personal items and uniforms. Ships officers have more space for personal items. Most of the ship's spaces are taken up by extra ammo, armor, troops, weapons, and engines. Displacement: 650 tons Hull Material: sandwich construction carbon fiber reinforced plastic
