Leonardo DRS provides integrated electric drive (IED) and hybrid electric drive (HED) ship propulsion solutions. HED arrangements can be gear-mounted or shaft-mounted.
Our motor and drive systems provide advantages in flexibility, modularity and commonality; supporting requirements for fuel savings and growing power efficiency demands on future ships.
Regardless of fuel prices, the more often you have to re-fuel a ship - when you are alongside the re-fueling ship - you are more vulnerable. The HED propulsion system gives you more time on station and less time at risk.

1.7 MW Shaft-Mounted Hybrid Electric Drive (HED) Motor
Leonardo DRS power dense low speed (120 rpm) permanent motor with large air gap allows for bearing-less configuration, which simplifies the propulsion shaft.
1.5 MW Gear-Mounted Hybrid Electric Drive (HED) Motor
Leonardo DRS lightweight permanent magnet motors allow for direct mounting onto the gear.
36.5 MW Integrated Electric Drive (IED) Motor
Leonardo DRS’ full electric drive permanent magnet motor.
Power-dense 625HP Hybrid Electric Drive (HED) Motor
Selected to provide hybrid electric drive propulsion for the U.S. Coast Guard Offshore Patrol Cutter program, the power-dense, water-cooled PA44 is only 395 lbs and rated up to 625HP providing 1,100 ft-lbs. @ 3000RPM.
Shaft-Mounted Hybrid Electric Drive (HED) Motor Configuration
Lower noise signature than gear-mounted motor.
Gear-Mounted Hybrid Electric Drive (HED) Motor Configuration
Compact arrangement with high shock capability.
