Marichka (Ukrainian: Марічка) is a Ukrainian-made multi-purpose autonomous underwater vehicle (AUV) capable of performing underwater attack missions, as well as cargo transportation and reconnaissance.
Marichka is designed to be capable of hitting landing ships, boats, submarines and missile corvettes, as well as coastal fortifications and bridge supports.
Outside of strike applications, the AUV can also transport military and civilian cargo, and perform reconnaissance missions.
The manufacturer claims that Marichka can be concealed from hydroacoustic search scanners and can withstand electronic warfare countermeasures.
