The Submarine TS1700 is a diesel-electric submarine of which conceptual design we developed. It is propelled with an Electric Motor, two diesel generators assisted with an air-independent propulsion (AIP) system. The platform can dive more than 300 m in depth. It can accommodate 25+6 SF personnel for 90 days at sea on double elastic platforms which prevent the personnel and the devices from devastating effects of underwater explosions. It enables the launch of a variety of 16 modern heavyweight torpedoes and guided missiles from its 8 tubes.

The submarine has a length of 60,14 m, a beam of 13,4 m, and can reach speeds of more than 20 knots.

Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel).
