MiDLAS (an acronym for Milli Dikey Atım Lançer Sistemi; English: National Vertical Launch System) is a vertical launching system (VLS) developed and manufactured by the Turkish defense contractor Roketsan for the Turkish Navy. It is designed to store and fire a variety of guided missiles, including surface-to-air, surface-to-surface, and anti-submarine warfare missiles from naval surface combatants and potentially submarines.
The system was developed as a domestic alternative to the American Mark 41 VLS following export restrictions. It was first integrated into the TCGİstanbul(F-515), the lead ship of the Istanbul-classfrigates. The VLS system is also offered for export.
Development
The development of MIDLAS began to ensure the independence of the Turkish Navy's strike capabilities. While the Ada-class corvettes were designed without a vertical launch system, the subsequent Istanbul-class frigate program initially planned to utilize the US-made Mk 41 VLS. However, following the imposition of CAATSA sanctions by the United States on Turkey in 2020, the procurement of the Mk 41 became restricted. In response, Roketsan accelerated the development of a domestic launcher that could interface with the Turkish-designed ADVENT combat management system.
First Ground Test: On December 3, 2022, Roketsan successfully conducted the first firing test of the system from a ground-based test rig using a Hisar-O missile.
First Sea Trial: On March 12, 2024, the system was successfully tested aboard TCGİstanbul(F-515), firing a navalized Hisar-D missile.
First Interception: In August 2025, the system successfully intercepted a Banshee Jet 80+ target drone using a Hisar-D RF missile fired from TCG İstanbul.
Design and specifications
MiDLAS is a modular, below-deck launching system featuring an open architecture that allows for the integration of various missile types. It uses a canister-based storage method, where missiles are loaded into individual cells. The system is designed to support both "hot launch" (where the missile ignites within the cell) and "cold launch" (where the missile is ejected by gas before ignition) techniques, although current integrations primarily utilize hot launch.
The system communicates with the ship's combat management system via Ethernet, specifically the Turkish Navy's network-enabled ADVENT system.
Configurations
Roketsan produces MIDLAS in two primary vertical configurations, along with single-cell variants for flexible deployment:
Tactical Version: Designed for medium-range air defense and anti-ship missiles.
A standard module consists of 8 cells with a footprint of approximately 6 square meters. The system supports "quad-packing," potentially allowing up to 32 smaller missiles to be carried in an 8-cell module.
Integrated Missiles
MIDLAS is designed to be compatible with a wide range of indigenous Turkish missiles:
Hisar-D RF: Medium-range air defense missile (Naval version of Hisar-O+).
