Background & Summary

The Karzelek Guided-Missile Destroyer is the result of a joint program to produce a vessel capable of screening the large and otherwise vulnerable Achilles and Perun which were already released by the time of the Karzeleks launch.

With ninty-six VLS cells, eight Moskit launchers, four torpedoes in two launchers and two UDAV-1 anti-submarine systems with a single 100mm deckgun the Karzelek offers the user a multi-role destroyer that is capable of offensive against air, land, sea and underwater targets. With SAMPSON, Artisan and SPY-3 the destroyer furthers its capabilities with significant redundancies and incredibly detection, targetting and navigation capabilities.

Tied in with the radars detection systems is the four Type 830 CIWS systems which have a range of 4km and fire the 20mm round. These specifically utilise the SPY-3 system in order to target incoming ordnance in priority and engage them as soon as they enter the firing zone, having targetting them prior to entering it. These Close in Weapon Systems, with the aid of the potential to use Surface-to-Air weapons inside the Ninty-six Mk. 41 cells allow a Karzelek to effectively operate as an Anti-Airborne Warfare (AAW) vessel.

The aforementioned VLS and eight Moskit launchers compliment the 100mm deckcannon in the Anti Surface-Ship Warfare (ASSW) section of its duties in being able to launch an effective offensive against any vessel it might come across. While a Karzelek would rarely dedicate its entire VL system to Ship-to-Ship missiles, it would take up a good chunk of its fore VLS. The Moskits have the ability to target a vessel from 120 km (75 miles) with a top speed of mach 3. This weapon system in particular allows the Karzelek to outrange older vessels while also maintaining a decent amount of destructive force with each Moskit having a total yield of 320 kg (710 lbs) or, on the rare occasion, a 120kt fission-fusion thermonuclear warhead.

The Karzeleks VLS comes into play again with the ships Anti-Submarine Warfare (ASW) capabilities along with its four torpedoes and an extensive SONAR suite. The ship is capable of detecting nearby submarines and launching either a Torpedo or an VL-ASROC at it within a decent engagement window of three to five minutes depending on the Submarines location. While the Karzelek is outfitted at sale for the Mk. 48 torpedo to be launched from its two launchers it is capable of being outfitted for the LY5755 'Charybdis' Heavy Torpedo.

Design

The Karzelek is one of the primary destroyers of the Triumvirate Navies. At a length of 150 metres, or 494 feet, it is a reasonable sized destroyer that fits nicely into the Multi-role category of which it was designed for.

Below the waterline of the vessel it is equipped with a SONAR pod that helps provide a good detection radius to the front of the vessel. The ship is also designed with a stabilisation ribs, two propeller shafts of which are connected to four turbines and two rudders to help manouverability. The hull of the vessel is lined with Kevlar over the more vulnerable areas. The propellers were designed for help reduce the noise emitted and insulated, along with the rudders, to prevent any ice from entering the gaps and freezing in artic circumstances. The four turbines of the ship are capable of propelling the ship to a maximum speed of 35 knots but find a comfortably cruise speed of 20 for a maximum range of 8,100 kilometers. At the rear and above the propulsion system sits the hatch for the 2087 toward array system, which is lifted out by a crane system and deployed/recovered from it. When not in use the 2087 area is covered by a two-hinged hatch to help maintain the safety of the vessel in storm conditions.

Above the waterline, the superstructure of the vessel is divided fore and aft of the main communications array. The fore superstructure is home to the bridge, crew areas and mounts for the SAMPSON, Artisan and SPY-3 arrays. Fire controls for the weapon systems are also present within this area of the ship. Aft of the communications array sits the hangar, rearward VLS an the smoke stacks for the turbines. Walking platforms along either side of the ship run the entire length and move underneath the four Type 830 CIWS systems present.

Capacity and Capabilities

A helicopter facility for a light helicopter is mounted on the aft section of the destroyer. While the ship is theoretically capable of supporting two such helicopters it is fitted at purchase with the ability for one only. This allows refuelling and rearmament facilities greater access to the helicopter in question and allows more room inside the hangar for the aforementioned weapons and fuel or facilities to repair or mount new modules onto helicopters.

Propulsion and Power systems

The destroyer is powered by four Sentenni LE5521 gas turbines which produce 28,340.25 HP each. This allows the ship to maintain a top speed of 35 knots through its two propeller shafts. Each shaft has its own rudder to improve preformance and turning circles which could be a vital component in sea-borne warfare. Its four bladed propellers have been specially designed to help reduce the amount of noise generated and are fully insulated against cold waters, much like the hull of which it is a part of.

Sensor systems

The Karzelek utilises the SAMPSON radar array which is a Solid-state, active electronically scanned array (or AESA) radar that operates to a range of 400 km. It is capable of switching between several modes including long and medium-range search, surface picture search, high-angle search and track, high-speed horizon search and being able to track multiple targets, multiple target tracking and fire control systems. Alone, the SAMPSON is capable of tracking hundreds of targets at any one time. Assisting the SAMPSON is the Artisan 3D Radar. The Artisan is an extremely modular and highly configurable to provide a high-performance radar solution. Artisan provides a 185km detection barrier for aircraft and 50km barrier for missiles and the ability to track over 800 targets at any given time. It's capable of providing a secondary navigation surveillance system, surface gun fire support and IFF interrogation coupled with its jammer suppression and surveillance abilities make it a logical addition to the Karzelek destroyer.

SPY-3, which is a radar capable of operating on the S and X bands for navigation and targetting with a range of over 321km. While the SPY-3 can perform most of its functions in either frequency band, for functions such as horizn search or precision tracking the band can be selected for current atmospheric, target characteristics and other factors such as anamalous and multipath propagation. Each of the eight SPY-3 radar plates on the Karzelek are capable of controlling Surface-to-air missiles and transmitting information to the CIWS onboard computers to allow them to reduce targetting time.

Its functionality is optimal for low-altitude propagation effects, narrow beam width for best tracking accuracy, wide frequency bandwidth for effective target discrimination and the target illumination capabilities for surface-to-air missile systems.

A SONAR house was mounted just behind the bulbous nose of the Destroyer to allow for a decent front-angle coverage with a 2087 towed-sonar array mounted at the rear of the vessel, below the helipad. The intention for providing the destroyer with such a indepth system was to compliment its ability to preform ASW roles with its VL-ASROC and torpedo launchers. This system, along with its abilities to engage air and sea-borne threats, help to improve its usefulness in a wise range of combat roles.

Weapon systems

The Karzelek is a Multi-Role destroyer, meaning that it is capable of fielding weapons effectively against both air, land, sea and underwater threats. It's VLS cells and 100mm deckgun are capable of engaging both land and sea-borne threats with the VLS cells being capable to further engage airborne and underwater threats using SAM missiles or the VL-ASROC Anti-submarine system. The Karzelek is also equipped with eight P-270 Moskit launchers which are capable of engaging Sea-borne threats from 120 km (75 miles) at a speed of Mach 3 and an explosive force of 320 kg (710 lb) of explosives or a 120 kt fission-fusion thermonuclear warhead.

The class also comes with four torpedoes in dual-launchers either side of the vessel and a total of four Type 830 CIWS systems which are capable of engaging targets 4km away at a rate of fire of 10,000 to 12,000 rounds a minute. Each Type 830 is capable of firing the 30mm round in HE-frag, Frag-T, APT, AP or Cargo-Carrying format. The CIWS is assisted with the SPY-3 radar system which allows the CIWS to target incoming ordnance or aircraft at a much greater distance before they enter firing range, allowing them to reduce response times.

The Karzelek is also equipped with two UDAV-1 Anti-submarine systems between the Moskit launchers, just in front of the bridge. The rocket system, while theoretically capable of engaging submarines, is intended to provide a multi-layer defense against both torpedoes and frogmen. Each system has a total of 60 missiles, including reloads, for 120 Anti-submarine and torpedo kill weapons aboard each ship. Each system consists of an ammunition loading device, firing controls and ground support for crew manning each of the weapon systems. Despite this hardlinks between the two launchers and the Bridge exists for operation from both the safety of the bridge in bad weather conditions or in active battle. In a summary, the UDAV-1 consists of the following;

A KT-153 remotely controlled multi-barrel automated rocket launcher with indirect elevation/traverse stabilisation;
111SG depth-charge rockets with HE warhead and impact-time fuze to engage underwater targets;
111SZ mine-laying rockets with hydroacoustic proximity fuze for remote mining of a water area to make a barrier for incoming torpedoes;
111SO decoy rockets to divert homing torpedoes from the surface ship by creating false acoustic target;
