The Signus Systems KJJ-108 Typhoon (Zhenian: KJJ-108 태풍), commonly the KJJ-108 Typhoon Armored Fighting Vehicle (AFV), is a line of tracked armored fighting vehicles developed in Zhenia. Developed for service in the Greater Eastern Union Defense Forces and as a replacement for existing tracked armored vehicles in service, it was developed into numerous variants, although the infantry fighting vehicle and armored personnel carrier variants are the most notable; the former was developed with the intent to defeat other infantry fighting vehicles and some tanks in mind, while the armored personnel carrier variant focused on personnel protection, survivability and networking more than its predecessors. As an infantry fighting vehicle, it is capable of transporting eight fully-armed infantrymen into battle, while the vehicle itself is normally operated by three crew members.
Development
Work on the KJJ-108 Typhoon initiated around the late 1990s, when the existing KJJ-80 Cyclone, although it had superb amphibious capability and was geared towards rapid, expeditionary warfare, was starting to become outdated. There were concerns regarding the survivability of the Z11, amid the development of infantry fighting vehicles and anti-vehicle weapons around the world; soon, it became clear that the KJJ-80 Cyclone, although a well-built platform aimed for fast-paced warfare often involving weapons of mass destruction, was not suitable and survivable in the battlefield of the 21st century.
With such circumstances in mind, proposals for what would eventually become the KJJ-108 Typhoon mainly focused on increasing survivability, even at the expense of amphibious capability; while the KJJ-80 Cyclone had waterjets for amphibious operations and had restricted its weight to under 25 tons, such design restrictions were removed when working on the new vehicle. While logistical restrictions - including its capability of being transported aboard the C-21 Cheonma - remained, selected proposals included a further emphasis on armor and survivability than overall mobility, allowing for the development of a platform that could serve a variety of tasks including APC, IFV, air defense and light tank roles.
The initial prototype vehicle, dubbed the Z21, was released in October 2006, its power pack issues, as well as the integration of caseless ammunition into the logistics network, delayed its introduction into service to December 6, 2008, when it was finally given its designation code KJJ-108. Prior to its introduction to service, however, the vehicle underwent an array of testing in extreme conditions, including both cold and hot weather testing.
Design
Layout
The KJJ-108 Typhoon, although following a similar general layout with existing infantry fighting vehicles, incorporates cutting-edge technologies developed after the KJJ-80, with a higher emphasis on modularity and survivability, evident with the existence of modular armor and the compartmentalization of the cabin with additional composite armor to ensure survivability. The vehicle is normally operated by three crew members - commander, gunner and driver - with the commander and gunner in the turret, while the driver is located on the frontal left side of the hull, just left of the power pack. Although the roles of three crew members is clearly distinguished, the commander can at times override controls over the turret (and in later variants, the vehicle itself) in emergency situations, theoretically allowing for the vehicle to be operated by only one or two crew member at times. More recent variants have even introduced unmanned turrets, effectively ensconcing all crew members within the well-protected hull, at the expense of its passenger capacity.
The basic chassis of the KJJ-108 line is designed with modularity in mind, allowing for one variant can be readily modified into another in a relatively short amount of time. The 3+8 crew capability allows for adequate space for other auxiliary equipment, such as command & communications consoles, 120 mm mortar systems, mobile gun systems and the like. In its infantry fighting vehicle configuration, it is air transportable via tactical airlifters within service of the GEUDEF.
Armament
Although a variety of armament options are available for other variants, the infantry fighting vehicle variant of the KJJ-108 Typhoon is equipped with a two-person turret, armed with a 40 mm autocannon capable of firing an array of rounds, including APFSDS, high-explosive, smoke, multipurpose and air-burst rounds. With the main gun directly connected to the vehicle's fire control system and gun stabilizer, the vehicle is capable of engaging moving targets while the vehicle itself is on the move with a great degree of accuracy. Later upgrades have allowed for the gun to fire caseless telescoped ammunition (CTA) rounds, adding to the vehicle's adaptability to various combat situations.
The multipurpose munition, in particular, can be configured on site via the onboard fire control system into a variety of modes depending on the situation, including armor-piercing, fragmentation, air burst and proximity. Each round contains a programmable fuse system that receives on-site information from the fire control system, allowing for a greater diversity of targets it is capable of engaging.
In addition to the 40 mm gun, the turret is equipped with the Eagle's Nest 12.7 mm RWS and a 7.62 mm coaxial machine gun as its secondary armament: unlike its predecessors and other vehicles, it was equipped with the 12.7 mm RWS since its introduction to service, minimizing the need for the vehicle-operating crew to exit the vehicle. A separate compartment towards the rear of the turret contains a total of four anti-tank guided missile launchers, augmenting its anti-tank capabilities.
