Technical Specifications
General information
| Length | From 1.8m (Base Vehicle) depending on configuration (Typical MCM 2.2m --2,3m depending on Navigation selected, Survey 2.7m) |
| Weight in air | From 49 kg (Base Vehicle) (Typical MCM 62kg, Survey 79 kg) Exact weight can vary |
| Diameter | 200mm |
| Depth rating | 500m or 1000m |
| Max speed | 5.5+ knots |
| Endurance | Dependant on configuration and speed. Typical: 6 hours at 3 knots (MCM configurations) and 4 hours at 3 knots (Survey configuration) With one battery module. This can be augmented by adding an additional battery module or by field swapping battery modules. |
