Background and Design
The Dolch Raketenpanzer, or "Dagger Rocket Tank," is a heavily armored Self-Propelled Air Defense (SPAD) vehicle based on the Feurig 2A2 platform. Dolch's early development followed immediately after Wolf Armaments' unveiling of its 2018 upgraded Panther Flakpanzer it referred to as the "Panther 2 Flakpanzer;" it featured a new sixty millimeter gun system and significant equipment/electronic upgrades. Realizing the gap present between tactical and long range air defenses within the Imperial ground arsenals, the TECT Imperial Army petitioned the Armed Forces Ministry for permission to seek out and acquire a vendor willing to deliver a longer ranged, highly mobile anti-air vehicle it could utilize in conjunction alongside its Panther 1 and now Panther 2 systems. Wolf Armaments, already in the process of developing an export platform of its own similar to specifications requested by the Imperial Army, was granted a contract tasking them with delivering a modified version of their platform that could be utilized on Panther/2A2 hulls. By the end of 2019, the "Raketpanzer" seen today became the finalist in the selection process created by the Imperial Army and the soon to be "Dolch" (Armed Forces corrected model with some modifications) would be approved for use within the Armed Forces. Delivery of the first wave of Dolch SPADs took place in early 2020, equipping many of the Imperial Army's armored forces with Dolch SPADs. After several waves of deliveries and minor modifications along the way, the Dolch SPAD has been approved for foreign export as of late 2022.
Similar to its older sibling the Panther Flakpanzer, Dolch was designed around concepts on mobile air defense strategies. Unlike traditional missile based air defense that is largely stationary, Dolch would be utilized more often not in mobile formations in order to avoid easy targeting from hostile forces. Such formations are intended to deny enemy aircraft access to airspace using mobile platforms that could accurately target aircraft and munitions while remaining flexible or temporarily stationary at will. This concept allowed vehicles like Dolch and units they would be deployed with access to complex layers of air defense even while on the move in active battlefields, something units often sacrificed mobility for in the past. Where the two air defense vehicles part, however, is the type of aircraft they specialized in targeting and how they take them down. Dolch, equipped with Harpune Tactical Air Defense Missiles (or "Harpune TADM"), was outfitted from the beginning to target high-flying, often long distance aircraft/munitions that were simply out of range for traditional air defense vehicles armed with either guns or MANPAD systems, or both; the Panther for example could detect most of these threats too but could not effectively engage them until they got within range of its guns and MANPAD systems. These types of targets often include faster flying objects like high flying fighter jets and drones, small and swift artillery missiles/rockets, smart ballistic/cruise missiles and rockets, air-to-ground missiles, and even low RCS or stealth aircraft/munitions. While the Panther did have its place within air defense, especially within TECT's mobile air defense strategies, it could not fulfill all the roles those strategies required. Heiliger Blitz, operating as a missile launching platform in this scenario, had fulfilled the role of long range and tactical range air defense up until this point within the TECT Armed Forces. Although capable, Heiliger Blitz lacks the necessary mobility, protection, and requires time to setup for fire missions and pack-up after those fire missions are over. Most importantly, it could not fire while on the move nor could it operate individually in almost all scenarios. As such, the Imperial Armed Forces required a stopgap to fill the roll of mobile platform and tactical range air defense if its air defense forces were to excel.
Dolch, built around the 2A2 platform, was largely based on the Russian Tor Missile System. Mounted to a heavily armored vehicle, the Tor System itself is a complex turret platform which utilizes turret-mounted radar guidance equipment and a missile magazine storing 9M330 missiles to shoot down guided weapons and aircraft. Tor's worth was proved over the years as operators worked to develop numerous different vehicle-based variants, land-based and naval variants, and clones/potential successors like the Dolch SPAD. Wolf Armaments originally began developing the Dolch in order to sell the system as an upgrade or replacement to Tor for countries using them, but the Empire's interest in the design altered the company's original plans significantly. Although largely inspired by Tor, Dolch was designed as an inspiration rather than a clone of Tor. While Tor focuses on defense against guided weapons, Dolch is utilized against most munitions and aircraft. Dependent on its selection is missiles, Dolch is can specialize on short, medium, and even long range air defense thanks to its missile magazine system and extensive guidance/communications equipment. These features also mean Dolch is far more capable than merely being an air defense vehicle.
Starting from top to bottom, Dolch utilizes a special electrically driven turret system that's truly the main feature of the Dolch. Capable of speedy full rotations, the Dolch's turret is unmanned but is equipped with most of the tank's operational equipment. Both radar systems, communications equipment, weapons systems, and even storage containers can be found on or within the turret. Mounted atop the turret is the Dolch's S-Band search radar system. Along with general improvements such as power output and equipment upgrades, this is the same 3D S-Band radar system found on the Panther 2. On the face of the Dolch, just like the Panther 1 and 2, is the Dolch's Ku-Band system which can be found on the newer Panther 2's face as well. Combined with optical sensors, the Ku-Band is a face-mounted tracking radar/optical system designed to track targets within visual range and improve the user's tracking efficiency while also increasing the number of targets capable of being tracked at any given time. Also found on top of the turret are the exit ports for the Dolch's missile magazine. Nearly as tall as the vehicle itself, the Multi-Platform Missile Magazine System or MMS is comprised of an empty mounting space capable of fitting most (if not every) known magazined/celled missile system available on the market. Operators can choose to mount cell-by-cell, or install the entire magazine into the turret. Although capable of utilizing most available missile systems, missile canisters must be three meters tall and wide; the entire magazine is fifteen meters long by twelve meters wide. Furthermore, numerous storage and equipment cases can be found surrounding the turret. These cases either fit actively used equipment (such communications or ECM equipment) or can be used to store field equipment crews may require while on deployment. Lastly, while not intended to be within reach of enemy ground forces, the Dolch comes standard with active protection systems on its turret. Standard systems include sixteen multipurpose eighty millimeter launchers and eight "shotgun" pellet dispensers that make up the "Shield" Active Protection System. For armor, the Dolch is protected from standard small caliber firearms and resistant to cannon rounds (14.5+)/RPGs.
Underneath the turret is the familiar Panther Flakpanzer chassis. Identical to the Feurig 2A2's chassis, the Panther's original chassis featured little changes aside from modifications to the turret layout. In the Panther 2, however, the turret section became completely unmanned. The entire section was replaced with automatic turret components and the crew moved to an armored "bath tub" where the driver's seat used to only be. Dolch, sharing the same chassis as the Panther 2, utilizes the same unmanned turret layout and crew space located at the vehicle's front. Aside from modernization upgrades made during the mid 10s, Dolch's chassis includes new sensor, camera, and lighting equipment. Furthermore, newer alloys used in the construction process has improved the Dolch's durability and weather resistance.
Armaments & Protection
Lacking in specified armaments unique to itself, the Dolch is a battlefield and theater support asset utilizing missile systems mounted within its magazine. The Multi-Platform Missile Magazine System (MMS) is an internal magazine system based off the Heiliger Blitz's cradle system. Rather than specializing in operating one single missile system, cradle systems like the Heiliger Blitz's and magazines like the Dolch's are optimized to use almost any missile system so long as their canister fits the correct dimensions. Marketed originally and primarily as an air defense tank, the Dolch is largely optimized for radar guided and command guided surface-to-air missiles. Only one missile in particular was developed for the Dolch during development and that was the Harpune Tactical Air Defense Missile, or "Harpune TADM." Detailed better in its own description bellow, TADM is a "tactical" medium ranged surface-to-air missile designed primarily for larger ground based air defense platforms. TADM is designed to engage higher flying, more maneuverable targets such as lower flying combat aircraft/drones (ground attack/fighter planes, helicopters, and MALE drones), and fast approaching munitions such as cruise missiles and glide bombs. However, Dolch's usefulness as a modular missile carrier extends its air defense capabilities to other missile platforms as well, such as other medium or long ranged missiles and MANPADS. Therefore, if wishing to fully optimize their loadout, a Dolch user may opt to split their cells between two or more missile systems to engage a wider range of airborne targets.
Another useful and unforeseen quality of the Dolch's MMS is the ability to utilize non-SAM missile/rocket systems, such as surface-to-surface missiles. While not intended to do so originally, an engineer late into Dolch's development noticed that the dimensions of the MMS' cells fit almost perfectly with that of Wolf Armaments' newly developed Spieß LRMSM. Shortly before release, Wolf Armaments tested the Dolch's compatibility with the LRMSM and other surface-to-surface missile systems. They found, much like surface-to-air missiles, there were no significant issues utilizing the LRMSM even while on the move; for example, testers in a Dolch were able to shoot down a slow moving helicopter drone and a moving truck using LRMSM guided by its own command networking. According to extensive testing, the Dolch is capable of utilizing almost all missile systems that are deployed in canisters/boxes so long as they're boxed and are within the MMS' dimensions; the only limitations discovered are that wire guidance is out of the question and hot launches present higher risks to the vehicle if mishandled - stable cold launches are recommended. This means that in theory, so long as guidance is provided when necessary, the Dolch can launch everything from most surface-to-air missiles, to even smaller surface-to-surface projectiles like guided artillery rockets and anti-tank guided missiles. Although some scenarios would require another asset to be networked together with the Dolch to provide guidance or targeting, many guidance equipment (such as optical cameras and emitters) can already be found on the Dolch or installed with relative ease. Missiles requiring visual, radar, or command guidance are fully supported without additional modifications.
Protection of the Dolch (outside of its inventory of missiles) is handled by a passive armor package and an active protection system. Similar to other smaller, heavily armored vehicles designed by Wolf Armaments, the Dolch utilizes the WA-STEEL armor layout. The newer 4.5 Generation of the WA-STEEL layout includes improved ARMOX ADVANCE steel alloy tiles along with improvements to the ceramics used throughout the armor package. However, the biggest upgrade to the package overall is the addition of a second two-layered armor layer protecting sensitive areas of the vehicle, namely the crew compartment and the turret's MMS. This layer is thinner overall when compared to the main tiles and is comprised of ARMOX ADVANCE alloy tiles beneath a softer Ti-5A1-2. 5Li (titanium alloy) layer. Once utilized in some older armor packages from Wolf Armaments, this configuration provides a soft surface that deflects most projectiles and heat-jets while the harder material bellow it full-stops whatever manages to push through the first layer; using this concept, a projectile/heat-jet will be slowed down or deflected/dispersed before hitting the harder surface that would normally be at higher risk of penetration if it were alone or not thick enough. To combat anti-armor munitions before they even make contact with the Dolch, the "Shield" Active Protection System is designed to defend armored vehicles utilizing multiple pieces of equipment mounted throughout the vehicle; by adding on equipment to the system, Shield's net of protection extends further outward, creating layers of protection for the Dolch. In Dolch's case, the vehicle comes standard with over sixteen eighty millimeter multipurpose launchers capable of using a variety of munitions (such as smoke or fragmentation), and at least eight "shotgun" pellet dispensers designed to engage rockets and missiles at very-close ranges before they make contact. To perform efficiently even without their human operators, the Dolch utilizes several cameras and over two dozen other sensors located throughout the vehicle to detect and engage threats automatically and/or manually. These sensors include laser designation detectors, radar lock-on detectors, infrared beam detectors, short ranged radars, and a series of camera systems. While not able to defeat every threat known to man using interference measures, the Dolch's APS includes laser duplicators to confuse laser designation, short range jamming system able to disrupt radars within close range, and the ability to lock onto infrared sources for counter-attack or designation for allied units.
Networking/Electronics
As a dedicated air defense vehicle, Dolch is equipped with numerous networking equipment and electronics that allow it to perform proficiently in its role. It is not only important that Dolch is able to conduct air defense independently, but as a make-shift mobile radar and launcher platform, Dolch should also be able to assume command/control of air defenses systems within any network. Any vehicle hoping to perform in such a position must come outfitted with not only powerful radar systems but also command and networking equipment most air defense vehicles most needn't require. Dolch comes outfitted with several networking and electronic equipment that allow it to independently conduct air defense operations, and to seamlessly integrate itself within battlespace networks in order to enhance its own lethality and boost the network's overall performance. These pieces of equipment include, but are not limited to, search and targeting radar systems, two universal antenna systems, high-performing electrical generator, and numerous computing systems more than capable of handling any battlenet's downloads/upload requirements.
While designed to slot into any existing battlespace architecture, the Eisen-Schloss Combat Network is the primary combat networking suit for TECT designed vehicles. Eisen-Schloss is an integrated and adaptive battlespace network that maximizes combat lethality, performance, and enables command and control on an unprecedented scale in any vehicle, unit, and device that uses it. Information is sourced not only from multiple origin points on the individual platform, but from every Eisen-Schloss equipped friendly vehicle within the battlespace, which provides constant informational updates across a broad spectrum of sources, both known to the operators and those operating below their awareness. At the most basic level, the Eisen-Schloss Combat System aims to accelerate engagement cycles and increase operational tempo at all levels of the battlefield. This acceleration is achieved by providing a mechanism to rapidly gather and distribute data, and rapidly issue directives according to that information or by operators on the network. Eisen-Schloss' ultra-high speed networking permits error-free, high integrity transmission in a bare fraction of the time required for voice-based transmission, and permits transfer of a wide range of data formats, from a multitude of compatible sources. In the hands of an air defense platform such as the Dolch, Eisen-Schloss can provide and even receive valuable assistance in real time that could change the tides of battle. Support assets part of the network, such as AWACS who provide extended radar coverage over a region, can detect and track targets outside of the Dolch's radar range, allowing a Dolch system to fire its missiles at maximum range without ever emitting its own radars and striking targets with guided precision at no cost of retaliatory/SEAD strikes. On the other hand, the Dolch's radar and command infrastructure can provide connected local units (such as MANPADS or SPAAG) access to the Dolch's intelligence gathering tools as well as coordinate fire missions to improve combat effectiveness.
But as with all tactical air defense systems in Imperial use, the Dolch relies on the 'Harpoon' Fire Control System. The 'Harpoon' FCS is an independent targeting & solution computing system for the Dolch SPAD and other air defense systems designed in TECT; it is designed to target detected objects, identify them as friend or foe, and provide ease-of-operation for the operator in target elimination if necessary. 'Harpoon' utilizes every attached information gathering tool along with battlenet information to detect, track, and eliminate identified targets. In the Dolch's lineup, two mounted radar systems are used to detect and track incoming threats from over fifty kilometers away; through the Eisen-Schloss system, Dolch can also track targets detected beforehand and engage them once they are within fire range - essentially eliminating engagement time immensely. For air search and tracking, the Dolch uses an S-Band 3D radar unit mounted atop the rear of the turret. Capable of rotating a full 360°, the Dolch's Tactical Air Scanning & Tracking (TAST) 3rd Generation S-Band is capable of detecting and tracking more than sixty targets up to and around fifty kilometers from the vehicle. Designed to operate in high-jamming environments, the latest 3rd Generation radars used by the Dolch and Panther 2 utilize clutter suppression technology, target interrogation/shifting software, communication antennas linking guidance to missiles directly, and counter-jamming technology to reduce hostile jamming effectiveness. Even while moving, the Dolch's S-Band is easily able to operate on monopulse tracking modes, and even fire missiles while at safe speeds. If need be, the S-Band is capable of folding in either direction for storage purposes. Dolch's second radar suite is the K-Band Targeting Radar System mounted to the turret's face. Specifically designed to operate in heavy jamming environments, the 3rd Generation K-Band along with being a thin PESA system is equipped with all of the upgrades seen on the TAST. However, to increase its reliability in even the heaviest of jamming environments, the K-Band is also equipped with an optical suite designed to compliment the radar system's pulse doppler with multi-spectral visual data.
'Harpoon' as a fire control system allows ease of selection of what weapon system should be used to engage a target by providing detailed information on incoming threats and analyzing them. Lighting fast computation analyzes detected targets and provides both an identity to the target and a solution to bringing it down. This fast response time essentially bridges together quick targeting time and fast engagement responses which in the end only requires the operator's prompt decision on how to proceed unless the Dolch's automated responses are enabled. While not important to Dolch specifically, the 'Harpoon' system also assists in the automated firing of gun systems using gun-mounted sensors and targeting equipment/software to achieve accurate guidance. Rounds are automatically fired "ahead" of targets, meaning gun systems will fire at target solutions in multiple possible fashions to intercept the target by firing farther down path where the target will eventually be. By predicting the path of the flying object and firing on that path, it allows highly accurate munition placement that will destroy the target with vast amounts of scored hits. In Dolch's situation, 'Harpoon' acts as a guiding force determining what missile should be used, how many, and assisting missile guidance systems in intercepting targets. 'Harpoon's' ability to also categorize targets more efficiently at lightning speeds gives the Dolch an edge against potential swarm attacks by isolating non-threatening targets, categorizing incoming targets according to danger they pose, and allowing operators to engage all targets efficiently at high success rates. Not to waste even an already fired missile, 'Harpoon' is even able to redirect already fired missiles if their original target has been determined to have been destroyed (typically tipped off when their speed and altitude drastically stop or they disappear entirely off radar).
These systems, including the Eisen-Schloss Combat System and interaction systems, are protected from electromagnetic interference or EMP-based attacks using encryption and anti-electromagnetic technology. Furthermore, reduction in effective jamming utilizing the above methods drastically improves the Dolch's capability in even the most horrendous battlefields imaginable.
Propulsion/Mobility
Not surprisingly, the Dolch is powered by a VMA Type-75E-3 Liquid-Cooled V-12, Twin-Turbo, Multi-Fuel, Engine - same as its two ancestors, the Panther Flakpanzer and Feurig 2A2. Additional electrical power and electrical storage is provided by the VMA Heavy Duty Series of generators and batteries, which were designed for heavy vehicle applications. Von Maier Imperial Automotive Group, the designer for both the engine and electrical equipment, designed the Type-75 for main battle tanks and other heavily armored vehicles while the Heavy Duty Series was originally developed for VMA's larger construction vehicles. Type-75 was specifically designed in the early 1970s for Wolf Armaments' in-development Feurig 1A1 and would later be used in several other Wolf Armaments armored vehicles; various models of the Type-75 can be found within the Empire and abroad, used in everything from heavily armored vehicles to large construction vehicles. Type-75 engines are known for their high compression and very high power to displacement ratio, allowing it to pour out vast amounts of power even for its smaller comparable size to other twelve cylinder engines; Type-75E-3 has over fifteen hundred metric horsepower and produces just over eleven hundred kilowatts of power at twenty-six hundred rotations per minute. The more recent E models have several improvements including new piston designs and all new fuel injectors that improve fuel efficiency. As with traditional methods, the engine is located in the rear of the tank, strategically placed in the rear half of the vehicle where it is protected and has in-place protection systems to protect the crew from engine failures. Identical to its ancestors the Panther Flakpanzer and Feurig 2A2, the Dolch boasts high mobility and agility compared to previous bulkier generations of Wolf Armament tank designs.
Heavy Duty generators and batteries were more recently developed in 2012, used in some of VMA's largest vehicles and equipment while also being sold to manufacturers in the same line of work. Electricity Military Generator Mark 2 is a vehicle mounted electricity generator part of the Heavy Duty Series designed to be used in or with military vehicles/equipment; notably, the EMG2 is found on a number of Imperial military support vehicles requiring electrical power generation without running their engines. Heavy Duty - Battery 2, similarly, was developed as a long-term, large storage battery for use with heavy vehicles and equipment. Although cranes and other stationary equipment, along with large construction vehicles use the original model, the second model is aimed at storing electricity long-term for military vehicles. Meant to be temporary in case of emergencies, Heavy Duty Series batteries' large storage capacity allows for power hungry equipment, like main battle tanks, to function even without active power sources for often several hours at a time.
EMG2 and HD-B2 can be found adjacent to the Dolch's engine within the same compartment. It serves as an efficient alternative to electricity generation when the engine is not running. Traditionally engines produce enough electricity to not only operate the vehicle, but bleed off extra power that would be either wasted or stored in a battery. Like many less mobile vehicles within the Empire's military arsenal, the Dolch utilizes a special battery that extends its operational times long after shutting down the engine; in fact, for example, the Feurig 2 and 2A2 use similar technology/equipment to store electrical power for operating controls and other electrical equipment without having their engines online. This is because the Dolch will often be parked in one spot for long durations of time. One position could be kept for half a day, a week, possibly even forever if some operators simply have no need for the platform to ever move again. As such, the Dolch utilizes a generator and battery system to maintain electrical power without utilizing the engine. Doing so saves not only fuel in the long-run but also greatly reduces wear and tare on the Dolch's engine components. EMG2 runs off of fuel from the fuel tank and releases exhaust fumes into the same exhaust pipes the engine uses too. While some believe simply running the engine is easier or quicker, EMG2 is vastly more efficient with its energy production since in this scenario it is not powering the vehicle's propulsion. Rather, the EMG2 is supplying the HD-B2 with power to store for operation uses. So while the engine would be faster technically in this scenario, the EMG2 is vastly more efficient in fuel costs and engine part health; a plug-in outlet for heavy-duty charging cables is also present near the engine compartment (covered by a tight-fitting sealed lid) if an operator intends to connect the vehicle to a local power supply. Depending on operator uses, the Dolch's HD-B2 can store enough power to operate between twelve and twenty-eight hours without an active supply of power. Refilling the battery with power can take as long as three to four hours while the system is running on full power. Therefore, a stationary Dolch in low power use is capable of operating on a full tank of fuel for weeks, even potentially a month without needing refueling.
Unchanged from its predecessors, the Dolch uses a dual-padded, dual-plate center-guided track design utilizing both metal and rubber materials. Traveling at top speed, the Dolch can safely reach around seventy kilometers per-hour, especially on roads and other stable terrain. On rougher terrain, the Dolch should practice slower speeds and observe smart pathing due to its heavy load and large turret. Gas capacity is 1,200 litres (264 imperial gallons; 317 US gallons) allowing the Dolch to travel a little over five hundred kilometers on a full tank of fuel. In an attempt to counter inferred signature, exhaust pipes are water cooled and angled off to the sides of the vehicle to create more surface area and disbursement of heat. It is not recommended for the Dolch to conduct water crossings, however it is possible to do so with water standing around one meter in height.
Variants
Dolch System: Rather than buying the system itself along with the vehicle platform, customers may opt to purchase only the system itself, minus the vehicle platform. This works in either remounted turrets (Dolch turrets and air defense systems mounted onto new platforms) or Dolch System integration into other platforms. For example, the Dolch System can replace or bolster air defenses for warships by using its missiles and air defense systems aboard said vessel which has its own radar and air defense systems. Or similarly, a land based air defense system could use the same missiles, new launchers, and other radar equipment combined with Dolch System infrastructure to protect areas of interest.
