Schottel announced today that it will supply the full propulsion package for a new RoRo cargo vessel under construction at Bollinger Shipyards, Amelia, La. The vessel, named SpaceShip, is being built for United Launch Alliance (ULA) and is scheduled for completion in 2026.
Propulsion will be provided by three Schottel SRP 460 LE RudderPropellers, each rated at 2,814 hp (2,100 kW) with a propeller diameter of approximately 8.5’, Schottel said in a press release. The SRP units are electric L-Drive variants, with compact motors integrated directly into the thruster’s azimuth module. The setup is designed to reduce the mechanical complexity and footprint of the propulsion system while maintaining 360-degree steering capability, Schottel said. The vessel measures approximately 364’x82’ and is expected to reach a maximum speed of 15 knots.
Schottel noted that two STT 1 transverse thrusters, each rated at 500 hp (373 kW) with a propeller diameter of 4.3', will be installed to support maneuvering during docking and low-speed operations.
Schottel said it will also provide its MasterStick control system, which allows all five propulsion units to be operated simultaneously with a single joystick.
Electrical engineering for the propulsion system will be provided by elkon, a member of the Schottel Group. elkon will supply Active Front End drive technology, main switchboards, a power management system, an alarm control and monitoring system, and motor control centers. Bridge and engine control consoles and power distribution panels are also included in the scope of supply.
The Vulcan rocket is a heavy-lift launch vehicle developed by ULA. It is intended to replace the company’s Delta IV and Atlas V rockets. First launched in January 2024, Schottel said it can be equipped with up to six solid-fuel boosters, depending on mission needs.
