The nine metre by 7.4 metre vessel uses an Italian made ‘Black Scorpion’ torpedo system with a range of 3,000 metres.
It has a top speed of 50mph on water and 31mph while submerged, with a maximum dive depth of 250 metres.
Kronos is powered by a hybrid engine using an electric battery and diesel system – and has a 36-hour air supply for extended special op missions.
Onboard are high-tech reconaissance devices including an underwater drone and a quadcopter for aerial intelligence gathering.
The pilot navigates the sub using interior digital screens, but it can also be operated remotely as a stealth drone.
A Highland Systems spokesperson says sea tests have been ongoing for the past year. They said: « It is ready and tested, and is now undergoing modernisation and upgrades after results.
« We are installing a more powerful and quieter engine and electric batteries. »
The company say they cannot confirm Ukrainian deployment at this time, « but have other countries customers ready for placing orders. »
Upgrades to the vessel are expected to be completed by September, the spokesperson confirmed.
