view of 100 Littoral Combat Ship

Als ® Class 100 Littoral Combat Ship is designed to have the following main characteristics:

  • Suitable for operations in littoral waters and in open ocean areas
  • High speed and maneuverability
  • Sufficient displacement with high autonomy range and endurance
  • Capable to operate in a multi target environment and to cope with any kind of asymmetric threats
  • Has strong defence capability against any type of threats like missiles, aircraft, helicopter and submarines
  • Stealth design with reduced acoustic, thermal and magnetic signature, without unreasonable increase of the cost
  • Innovate CODAG or CODAD Propulsion with a speed of up to 30 knots
  • Installation of any state-of-the-art weapon system and sensor suit, corresponding to the multi purpose mission of the vessel, including the capability of installation of SM-2 missiles
  • Designed for ASW (Deployment of special forces and organic 10 t helicopter)
  • 3D Air & Surface Surveillance Radar or Integrated Mast (I Mast 400 - which incorporates most of the sensors and communication systems). Other masts with different radar and sensors suit can be also easily incorporated
  • Accommodation for up 113 persons plus 16 special forces
  • Designed in accordance with Standards for Naval Surface Ships
  • The design of the vessel can be easily adapted to the specific requirements of the customer
  • Due to its flexibility, the design can be adopted from many navies resulting to the reduction of the development the building cost.

Platform Design

State of the art hull lines based on stealth shape requirements. For ship’s resistance reduction a bulbous bow is incorporated. Particular attention is paid to the design of the aft end lines to achieve smooth inflow to the propellers, to reduce propeller induced vibration and to optimize propulsive efficiency.

Material construction

Main hull: High tensile steel
Superstructure : Steel or Aluminum

Used standards

Germanischer Lloyd Rules for Classification and Construction.

For cost reduction commercial standards throughout, except in the areas where naval standards are considered necessary for safety, survivability and operability reasons (shock requirements, NBC Citadel, etc.) can also be used.


Optimized radar signature by using the shaped hull form (Stealth design). For reduction of the Infra-red (IR) signature an injection system for cooling of the exhaust gases of the propulsion engines and a spraying system for pre-wetting of the outside areas in case of NBC condition are provided.

Reduced acoustic signature by flexible couplings and resilient mountings.

The vessel has sufficient displacement and endurance combined with operational capabilities to cope with all assumed types of threats within the specific mission area.

The Corvette is suitable for operations in littoral waters and in open ocean under harsh weather conditions.

The vessel has strong self defence capability against any type of air threats like missiles, aircrafts helicopters, UAVs.

The Corvette is based on a balance of mission payload, capacity, manoeuvrability, signature reduction and survivability to ensure tactical superiority.

Main roles

  • Surveillance
  • Law enforcement
  • Patrol and Surveillance,
  • Peace support operations,
  • Maritime Search and Rescue
  • Fishery Protection,
  • Command & Control

Warfare missions

  • Anti Surface Warfare (ASuW),
  • Anti Submarine Warfare (ASW),
  • Anti Air Warfare (AAW) - capability according to the no of ESSM missiles and the tracking and illumination radar
  • Littoral Warfare / Asymmetric Warfare,
  • Naval Gunfire Support,
  • Electronic Warfare (EW)


Optimum design

Optimum relationship between price and performance is achieved with the proper combination of commercial and naval standards.

Flexible platform

A flexible and reliable basic platform in which the desired level of equipment and armament is accommodated in such a way that an optimum relation of accommodated systems and equipment to vessel’s size is achieved.

The flexibility of the design enables the final product to be customized to the Customers’ requirements.
