MİLDEN Submarines will have a length of around 75-80m, a beam of 7m, a draught of 6.5m, and a submerged displacement between 2,500-3,000 tons.
Unlike the REİS Class, MİLDEN Submarines will have at least one Reformer. Preferred for long-range missions, Reformer is preferred for large (over 2,000 tons) submarines. Both PEM Fuel Cell modules and Reformers to be used in MİLDEN submarines to be equipped with 300kW (400hp) AIP System will be designed and produced nationally, and the systems will also be developed domestically under the Submarine Propulsion System Components Development Project.
The PEM Fuel Cell modules, which will be manufactured locally by the company to be selected under the project, are intended to replace the BZM120 modules currently used in REİS Class Submarines in the following years. Unlike the Type 214 Class, which has two Siemens product BZM120 PEM Fuel Cell modules (each generates 120 kW power), Dolphin-II Submarines, as in Type 212A Submarines, have 9 (one backup, eight active) BZM34 PEM Fuel Cell modules that generate a total of 306 kW (400 hp) power.
Unlike the REİS Class, MİLDEN Class is expected to use locally produced Lithium-Ion (Li-Ion) batteries (LIB) with higher power and capacity instead of lead-acid batteries.
Unlike REİS Class submarines, which are currently under construction, and AY, PREVEZE, and GÜR Class submarines, which have a single compartment cigar-shaped hull form, MİLDEN class submarines will have a multi-compartment teardrop hull form.
The development activities of the GEZGİN National Cruise Missile are ongoing, and it is considered to be used for the first time on MİLDEN platforms. However, when the missile is ready, I expect it to be used in PREVEZE Class Submarines equipped with MÜREN CMS from the mid-2020s. ATMACA Block-II guided missile (submarine-launched Encapsulated ATMACA version) with both active RF and IIR seekers is expected to be used in both PREVEZE and REİS Class Submarines (CMS software modification is required).
