The designs were unveiled for the first time at IDEF 2023, which was held in Istanbul between 25 and 28 July 2023. All of the designs are in the conceptual phase, and the development process is still ongoing.
LCSUB
The Dearsan LCSUB (landing craft submarine) is designed to support amphibious operations by taking aboard 60 Marines and delivering them undetected to shore. The submarine is also capable of monitoring, detecting, and gathering intelligence on the amphibious operations area.
According to information provided by officials at the Dearsan booth, the submarine has two pressure hulls, just like the Typhoon-class submarines. Although the submarine is in the design phase, development is still underway, and CONOPS have not yet been defined, it could be used on large amphibious ships with a pool, such as the TCG Anadolu, given the size and range of the boat.
LCSUB is expected to have high maneuvering capability in shallow waters and be capable to enter restricted waters and littoral areas undetected. It’s capable to operate independently or as part of a group.
It will be equipped with a navigation and maneuvering system for safe navigation surfaced and underwater. The boat will also have damage control, stability and trim control, platform control and management systems.
LCSUB Specifications:
- Length: 29.9 m
- Beam: 5.2 m
- Height: 4.65 m
- Displacement: 180 tons
- Crew: 5 + 8
- Marines: 60
- Propulsion System: Electric
HDA-700
The amphibious submarine also has an attack variant called HDA-700, which is larger than the amphibious version and can be used in ASW and ASuW missions. HDA-700 will be a first-strike platform that can penetrate limited waters and coastal areas undetected.
The HDA-300 will be forward deployed and able to operate independently on missions lasting 10+ days without replenishment. The attack variant will be armed with 6×533 mm torpedo tubes for torpedo and missile engagement, while it can be capable to deploy mines and UUVs.
HDA-700 Specifications:
- Length: 36.5 m
- Beam: 8.1 m
- Height: 7.2 m
- Displacement: 700 tons
- Crew: 16 + 8 SFO
- Propulsion System: Diesel Electric optional AIP
AMT SEAL SUB
AMT SEAL SUB is a 19-meter-long, small submarine designed to deploy special forces and conduct special operations. The submarine has a displacement of 85 tons and can dive up to 75 meters deep. The propulsion system will generate power of 100 kW, which will allow a speed of more than 10 knots. The submarine has a beam of 2.5 meters and a draft of 1.7 meters.
XLUUV variant
Dearsan officials told Naval News that AMT SEAL SUB has an unmanned variant equivalent to an XLUUV. Naval News learned that the XLUUV concept is still under development. It could fulfil missions such as ASW, ISR and mine warfare.
