South Korea’s HD Hyundai Heavy Industries (HHI) and Peru’s state-owned shipbuilder SIMA have unveiled the HDS-MGP, a next-gen submarine concept for the Peruvian Navy.
After the basic design phase was completed, the project has moved towards industrial qualification and construction, which has laid the foundation for a Latin American submarine construction and sustainment hub.
Derived from HD Hyundai’s HDS-1500 export design, the HDS-MGP (Hyundai Design Submarine – Marina de Guerra del Perú) is a 65 m long and 1,500-tonne submarine.
This design has been customised for the Peruvian Navy’s experience and requirements in sync with the oceanographic conditions on the Pacific Coast.
The project not only aims to replace Peru’s old submarine fleet, but also highlights the country’s aim to build independent defence manufacturing capabilities.
This also marks a progression in the alliance between HHI and SIMA. Following a 2024 contract to build 4 surface vessels for Peru, the companies signed a submarine development MOU and formalised a joint development agreement in late 2025.
