Research Project/s summary/description:


Modern Surface Combat Vessels are required to carry out a wide range of missions including mine warfare (MIW), Anti-Surface warfare (ASuW) and Anti-Submarine Warfare (ASW). Modern warships are required to be agile with increasing level of speed and manoeuvrability to improve both their offensive and defensive capabilities. The defensive systems employed in the design and construction or combatants, are both passive and active in nature.


The passive systems influence survivability by the prudent arrangement of fire, blast and ballistic boundaries, shock qualification of the primary structures and installed equipment, adequate watertight division, redundancy of distributed systems, and redundant command and control positions.


The manoeuvrability and speed of a platform sometimes referred to as the agility, also influence survivability of a platform. It is recognized that the specific physical and structural arrangement of a naval combatants may be classified; however the relative improvement in survivability of varying commercial vessel arrangements may be compared to assess the relative change in survivability with varying passive systems and agility.


Active Systems rely on a layered self-defence approach with Anti-Ship Missile Defence as a ship capability or provided by other ships within the battle group. Other active systems include electronic warfare (EW) systems such as laser warning and sonar, communications and radar interception. Decoy Systems may also be utilised to protect the vessel from a variety of threats. The specific performance of various active systems available in the public domain shall be compared to establish the relative improvement in survivability against a variety of threats.

The proposed research project is intended to assess the relative importance, via a detailed analytical and statistical analysis of passive defensive systems versus active defensive systems. The project aims to examine if improvements in the survivability of a vessel can be afforded through significant changes to the design arrangement and compared against active defence systems.


This research will undertake an assessment of the survivability and the reduced damage envelope of a typical standard vessel design and examine the improvements in survivability that can be achieved through changes in design arrangement and the use of ballistic systems against a prescribed range of military threats. A similar range of military threats will be used and a comparison will be undertaken to examine the relative improvements in survivability that may be achieved with active defence systems. These will be based on public domain or assumed system performance data. The ultimate goal is to develop design optimisation tools to support design trade off decisions and better inform future naval designs.
