VICTA
Where innovation, technology and experience combine to create the world's most advanced diver delivery unit – VICTA.
VICTA combines the characteristics of a fast surface craft with those of a submersible. It moves quickly and seamlessly from surface to sub-surface and this transition, along with its performance in both domains is enabled by an innovative fly-by-wire control system.
Impressive performance on the surface (c40kts and 250nm endurance) is matched by equally striking specification under water where 4hrs endurance is sufficient to navigate 2 crew and 6 divers for 25nm.
Compatibility with a standard ISO shipping container make it widely deployable and the experience of a former Special Forces operator and SDV pilot with over 28 years surface and sub-surface operational experience has enabled a design that reflects the needs of the operator.
VICTA enables the inconspicuous insertion and extraction of mission-ready capability at range and as such, it broadens the spectrum of operational options on offer to commanders of Maritime, Joint and Special Operations.

Defence application: concept of operations
Easily transportable intra and inter theatre using in-service strategic and tactical lift assets (fits in a standard ISO shipping container), VICTA is designed to operate independent of strategic assets and particularly from vessels and ports of opportunity. Able to deliver a team of Special Forces operators up to 250 nm on the surface and, transitioning to the subsurface mode 12 nm from the target area, it can deliver the team close to their operating area using personal rebreathers for the final infiltration to ultimately deliver land effect.
Future development of the Diver Delivery Unit family will deliver full autonomous capability both on the surface and sub-surface. As such, this technology will deliver across the full spectrum of maritime capability from intelligence, surveillance, reconnaissance and target acquisition to maritime interdiction operations, delivery of sensors to kinetic action. The Diver Delivery Unit family is equally relevant in the home land security and constabulary roles as more traditional defence roles.
