A flechette cartridge is provided, containing a plurality of flechettes, capable of firing the flechettes in a concentrated and accurate spread pattern upon firing. In particular, both low and high velocity flechette cartridges are provided, which accurately disperse flechettes in a concentrated spread pattern. The flechette cartridge minimizes the parasitic launch mass to maximize flechette payload, flechette velocity and kinetic energy, and to maximize target effects. The flechette cartridge provides a robust means for reliably stripping the flechette payload cup.

1. A flechette cartridge comprising: (a) a cartridge case having: (i) a base; and(ii) a cartridge case body having an outer circumference adjacent the base, and an inner circumference opposite the outer circumference, said inner circumference defining a smooth-bored cartridge barrel, the smooth-bore
1. A flechette cartridge comprising: (a) a cartridge case having: (i) a base; and(ii) a cartridge case body having an outer circumference adjacent the base, and an inner circumference opposite the outer circumference, said inner circumference defining a smooth-bored cartridge barrel, the smooth-bored barrel having a open mouth at one end thereof; and(b) a sub caliber payload cup slidably disposed within the smooth-bored cartridge barrel, the sub caliber payload cup having: (i) a payload cup body having an outer base, an outer circumference adjacent the outer base, an inner circumference opposite the outer circumference, and an inner base opposite the outer base; and(ii) a flechette retainer for retaining flechettes, disposed within the inner circumference; and(iii) a plurality of flechettes retained within the flechette retaining means; and(c) a tether in communication with the cartridge case at a first end, and with the payload cup adjacent an end opposite the first end,wherein, when the flechette cartridge is fired, the subcaliber payload is propelled from the smooth bored cartridge barrel and, at a predetermined distance from the smooth bored cartridge barrel, the tether acts upon the subcaliber payload cup to strip the payload cup from the flechettes, and allow only the flechettes to continue direct forward travel. 2. The flechette cartridge of claim 1, wherein the payload cup body further comprises a metal disk disposed therein, within the inner circumference of the payload cup body, adjacent the inner base. 3. The flechette cartridge of claim 1, wherein a barrel ridge is formed on the smooth-bored cartridge barrel, and a payload cup ridge is formed on the payload cup, adjacent the outer base thereof. 4. The flechette cartridge of claim 1, further comprising an ogive cap removably disposed on the cartridge case adjacent the open mouth of the smooth bored barrel. 5. The flechette cartridge of claim 1, further comprising a metal disk disposed within the cartridge barrel between a low pressure chamber disposed within the cartridge case and the payload. 6. The flechette cartridge of claim 1, wherein an empty volume is present within the cartridge barrel between the payload cup and the open mouth of the smooth-bored barrel. 7. The flechette cartridge of claim 1, further comprising a closure disk disposed within the cartridge barrel, adjacent the flechettes and flechette retaining means of the sub caliber payload cup.
