The Selah Shipyard Logistic Support Vessel is designed to enhance naval operational sustainability by ensuring continuous logistical support for surface combatants. In modern naval doctrine, the effectiveness of frigates, corvettes, fast attack craft, and mine countermeasure vessels depends not only on their combat systems but also on uninterrupted fuel, maintenance, and supply chains. This vessel directly supports that requirement.

Operational Role and Mission Profile

The ship is capable of:

• Providing shore power supply to naval vessels at port or anchorage
• Transporting fuel (marine diesel and JP-5 aviation fuel)
• Supplying fresh water
• Carrying ammunition and general cargo
• Deploying repair and maintenance teams
• Supporting SAT (naval special operations) units

Its operational concept focuses primarily on port and anchorage support but extends to limited at-sea refueling operations through a stern float system. This capability reduces dependency on fixed naval bases and enhances operational endurance of task groups.

Platform Architecture

The vessel follows a conventional auxiliary ship architecture optimized for volume and cargo efficiency. Key architectural elements include:

• Segregated fuel tanks for marine diesel and JP-5
• High-capacity fresh water storage
• Heavy-duty 18-ton service crane
• Helicopter landing deck rated for 15-ton general-purpose helicopters
• NATO and Turkish Armed Forces communications integration

The helicopter deck enables vertical replenishment (VERTREP), personnel transfer, and medical evacuation operations. Publicly available sources do not specify whether a hangar facility is present.

Survivability and Self-Protection

As an auxiliary platform, the vessel is not heavily armored. However, it is equipped with a 12.7 mm STAMP remote-controlled weapon station, providing protection against asymmetric threats such as small boats or low-level security risks.

The system is intended for defensive deterrence rather than high-intensity naval combat. In high-threat environments, the vessel is expected to operate under escort of combatants.

Advantages and Limitations

Advantages:

• High fuel and water capacity relative to vessel size
• Capability for limited at-sea refueling
• Helicopter support capability
• Multi-role logistical flexibility

Limitations:

• Limited speed (12 knots maximum)
• Minimal organic air or missile defense
• Not designed for independent operations in high-threat combat zones

Publicly available information does not specify total production numbers or detailed deployment history.
