The Danuvia VD.01, also known as the Forte VD.01, is a Hungarian machine pistol.
The VD.01 was designed by Robert Vörös in the 1980s, and he received a patent for the weapon in 1989, with Danuvia later purchasing the patent in 1994. Laszlo Paulenka, the then-director of Magyar Fegyvergyarto KFT in Hungary, provided great assistance during the experimental stages of the weapon, with several prototypes hand-made and shown off at DM4500. When Danuvia purchased the patent, they made modifications to the weapon's design and designated it the VD.01, however production for the weapon was stopped in 1998 due to financial reasons, with Intermodul Weapon Shops, an export/import weapons dealer, purchasing all rights, machinery, unsold guns and parts and marketing the weapon. Approximately 100 VD.01s were made before production was halted.
The weapon uses a simple blowback system to fire. It accepts proprietary 33-round helical magazines. It has a cyclic rate of 330 rounds per minute.
- The VD.01 has gained attention due to its odd shape and distinctive helical magazine.
