Survivability – Signature Reduction
ADA Class Corvette is designed with maximum domestic contribution utilizing state of the art technologies to reduce Radar Cross Section(RCS) Infrared Signature(IR), Magnetic Signature and Underwater Noise Level. In order to achieve this goal, a “Signature Management” methodology has been applied since the initial ship design phase.
Hull and superstructure geometry have been assessed with computer aided RCS estimation tools and necessary measurements have been taken during the design to have a low IR signature profile to reduce the diffrence beetween Ada Class Corvette’s IR signature and the environment. Ada Class Corvette has an IR signature management system both to display real time IR signature and to assist deceding the best signature reduction measures.
Design efforts have been greatly focused on minimizing vessel’s acoustic signature to improve sonar system effectiveness and to reduce the detection range of the passive sonars of the hostile submarines.
A nationally designed and developed Degaussing System has been installed to minimize the magnetic signature for protection against the magnetic mines.
Collective Protection Zones are designed to ensure the ships ability under NBC conditions.
Hull Structural Design
Turkish Loyd Rules for Naval Ships (2004) and national/international naval architecture and survivability standards and norms have been applied for hull structure design.
Domestic Product High Strength Steel (DH36) has been used for hull and superstructure construction.
Fore and aft masts and the funnel have been constructed with sea resistant aluminum alloys.
Advanced engineering techniques have been applied for scantling and analyzing hull structures.
A fully 3-D computer model has been developed for construction, outfitting and ergonomic design.
Main Propulsion System (MPS)
A total of 32 MW propulsion power generated by one gas turbine and two diesel engines is transmitted through two controllable pitch propellers via cross connected gearbox. Engine overhaul intervals are increased and the life cycle cost is decreased due to the capability of one diesel engine driving two shafts at the cruising speed. The reliability of the MPS at all conditions has been kept at the maximum possible level.
Design of electrical system of ADA Class Corvette is based on high reliability and survivability. The ship is equipped with 4 service diesel generators with 560 kW output power each.
Power distribution system complies with NATO standads.
- 440 V, 3 phases, 61 Hz is output of generators and main source for systems and devices
- 220 V, 60 Hz is used for lighting and appliances
- 115 V, 60 Hz is used as a secondary source for systems and devices
- 115 V, 400 Hz is obtained by static converters for power requirements of helicopter and electronic devices
- 24 V DC emergency system will supply electrical power for vital systems in case of a failure of main sources.
The power generation and distribution systems are designed and manufactured by the domestic industry.
Integrated Platform Control and Monitoring System (IPCMS)
ADA Class Corvette is equipped with a highly sophisticated Integrated Platform Control Monitoring System (IPCMS) to maintain continuous and reliable operation, reduce reaction time and simplify ship management.
Main propulsion system, electrical power production/distribution system and other ship service systems will be controlled, managed and monitored by IPCMS.
Human machine interfaces are configured via user-friendly Graphic User Interfaces. Users can apply changes on IPCMS graphic monitors and control parameters, form new pages and add new control parameters.
Increased availability of the system is obtained by redundant data transfer lines and operation of the user stations in multi server concept. In case of damage in one of the data lines, the system is designed to operate with an alternate data line without any interruption.
Ada Class Corvette is designed to accommodate 106 own personnel and flight crew in total.

- TS 6415 “Workspace and Human Dimensional Factors in Design of Military Materials” have been taken as guidelines in design.
To achieve NATO-ANEP-24 criteria, a minimum distance between mess rooms and galley has been aimed. For this reason, officers’, chief petty officers’ and petty officers’ mess rooms are located at the same deck with the galley. An elevator is fitted for food transfer to the lower deck where Ratings’ mess room and deep freeze. supply stores are located.
The ship has an infirmary and auxiliary facilities like laundry. barber shop, canteen etc.
Ship Handling-Maneuvering&Mooring Spaces
The ship has four maneuvering spaces. Under forecastle and port-starboard maneuvering spaces are designed as closed regions in order to reduce radar cross section. The helicopter platform is also used as aft maneuvering space.
There are two Rigid Hull Boats (RHIB) onboard. One of them with its davit is located at port side of the ship. The second RHIB is located over the steering gear room with a boat ramp.
