The TDI Vector (also known as the KRISS Super V) is a new breed of submachine gun that intends to revolutionized the way all future submachine guns are designed. Beginning in 2006, a 5-year joint development period alongside the experts of the US Army ARDEC Picatinny Arsenal ultimately produced a revolutionary new system to which KRISS USA marks as "the first major breakthrough in weapons operating systems in more than 120 years". The firearm subsequently entered production under the banner of Transformational Defense Industries (TDI) beginning in 2009. The Vector is expected to generate interest from special forces/military forces, security groups and the civilian market worldwide. In the military and security markets, the Vector showcases promising qualities for CQB (Close-Quarters Battle), particularly in urban settings. The Vector may also prove suitable for second-line logistical units as well as vehicle crews needed potent, compact firepower with accuracy.

Submachine guns have long held a distinct existence on the battlefield as well as in service with security and police forces worldwide. They came into their own during the close-quarters battles of World War 2, being fielded by all sides in several noteworthy examples to include the British Sten, the German MP40, the American "Tommy Gun" and the Soviet PPSh-41. Submachine guns helped to fill the void between service rifle and squad support machine guns by providing for machine gun-like repeating firepower within a compact pistol-like form. Since their large-scale introduction and subsequent use in combat, the concepts behind submachine guns had remained largely unchanged with a few minor exceptions.

What makes the Vector unique in the world of small arms is its use of the KRISS Super V System (KSVS) recoil absorption system. The firearm is designed utilizing an "in-line" approach in which the major internal working components and firing function follow an imaginary line from barrel to stock. The idea behind the approach is the centralizing of physical forces to work in conjunction with the operator's grip to help reduce inherent recoil and muzzle climb - two detrimental factors to the accuracy of any firearm. The design approach reportedly results in greatly increased accuracy, recoil reduction (by as much as 60%) and nearly no muzzle climb whatsoever even when the weapon is fired on full-automatic.

Traditional submachine guns have relied on a recoil absorption method that has always included the operator's body, particularly the shoulder region, to help brace the weapon. This undoubtedly would lead to variable results in accuracy and muzzle climb reduction becomes dependent upon the operator himself and can lead to readjusted aim and repositioning of the weapon during periods of sustained fire - either in burst and full-automatic fire functions where round-by-round accuracy is always desired. The Vector, on the other hand, utilizes its in-line profile as a means to maintain a straight line between weapon action and operator to help deliver more rounds against a target in repeated fashion. In fact, landing one round directly behind the other had been achieved utilizing a KRISS 2-round burst in tests.

The Vector makes use of the Delayed Blowback firing operation and is chambered to fire the .45 ACP or .40 S&W cartridge depending on model. Outwardly, the Vector takes on a very distinct, somewhat futuristic form. The trigger unit and integrated pistol grip are set to the rear as in any conventional firearm. The major working components, however, are all situated in the forward lower portion of the receiver, including the all-important barrel. The weapon is conventionally fed by way of a 13-round detachable box magazine but a 30-round extended magazine version is available as an option. Sights consist of a flip-up iron front and rear installation and a base MIL-STD-1913 Picatinny rail appears standard across the top of the receiver (as well as a shorter rail area below and forward) for the use of specialized optics and accessories (forward vertical grip, flashlight, etc...).

At the time of this writing, the Vector family comes in three production forms: the "Vector SMG", the "Vector CRB/SO" and the "Vector SBR/SO". Vector SMG is the base model that sports a 5.5" length barrel as well as offering selective fire. The Vector CRB/SO and SBR/SO are carbine forms with the latter being a short-barreled version - 16" barrel and 5.5" barrel respectively. The CRB/SO is easily identifiable by its longer protruding barrel and both of these models are semi-automatic in nature. All three models sport a folding stock assembly for increased portability and all three systems weigh in at less than 6lbs. Civilian-minded models naturally come in only semi-automatic fire modes.

A .50 caliber heavy machine gun product is currently in development between TDI and the US Army ARDEC Picatinny Arsenal to produce a highly modified, accurized version of the fabled Browning M2HB heavy machine gun system. Like the Vector before it, the end-product will feature a version of the KRISS recoil reduction system as the project intends to reduce the inherently violent recoil of such a heavy gun system by as much as 90%.
