Information technology and Indian Navy The advent of information technology has not only enhanced the combat capabilities but also revolutionised the communication systems in the Indian Navy, notes Bidanda M Chengappa.
Today modern fighting navies the world over rely on Information Technology (IT) which has emerged as an effective ‘force multiplier’ or tool to increase combat capabilities in contemporary warfare. Essentially armed forces everywhere face a paradoxical situation because they need to fulfil their tasks with decreased resources and reduced manpower. This necessitates working smarter and looking for ‘force multipliers’ and IT is increasingly used to manage this paradox.
Accordingly, the Indian Navy (IN) also emphasises the importance of IT especially in communication, information warfare, weapon systems, network centric warfare, logistics and simulation. Also the nature of warfare has become information driven like activities in other spheres of life.
Communication Networks: An effective and reliable communication network is a vital asset for any organisation. The Indian Navy has implemented a state of art data network connected up to the field units. The Naval Enterprise Wide Network (NEWN) links up the command headquarters at the apex to field units or warships at the fighting end. Warships at sea are now being linked to this network. This network is based on the latest IT concepts with enough security overlays and is meant to handle futuristic trends in communication for the next decade. Apart from this, various access network technologies particularly the satellite communication are being used for credible real time data linkage and communication within the Indian Navy.

Information Warfare: Information warfare is an emerging area in the IN's plans. The concept of Information Warfare (IW) is not new. It basically comprises defensive methods of denying enemy access to our own information systems as well as offensive methods of getting into enemy systems to disrupt their smooth flow of information. Today the methods for entering the enemy's decision making cycle and gaining insights into his strategy are powered by Information Technology. Also information of superior quality is required to be made available to oneís own commander in real time, thereby enhancing his battlefield awareness.
Therefore IW envisages a large gamut of activities in a future war scenario. It is only another tool which makes warfare more complex. It is a different approach to warfare and is likely to make heavy demands in the future. The success of IW largely depends on the technological superiority, the extent of one's dependence on electronics for warfare and the extent of networking of its information systems. The Indian Navy has realised the importance of IW and large thrust is now being given to strategic studies, technology up gradation and research work in this field.
Naval Weapon systems: rely on split-second decisions often made by human elements for activation. But before and after the decision is made, the weapon system has to perform extreme computations which have to be extremely fast and precise. Therefore at the heart of every weapon system is a computationally intensive control system which has to be fast, accurate and overly reliable. To meet these requirements deftly engineered embedded systems are being employed which run customised implementation of rugged Real Time Operating Systems.
Network Centric Warfare : (NCW) visualises a paradigm shift from the normal platform or ship-centric warfare to a network centric warfare at sea. It basically relates to linking of combat units at sea like warships, submarines etc into a common shared awareness network in order to obtain information superiority and enhance decision-making. In contrast to traditional operations that are considered to be platform-centric, network centric warfare focuses on passing information rapidly among different entities to increase their ability as a whole to respond to threats. NCW sees the combat elements of the navy as "nodes" in a network. The capability of such a network is typically defined by the Metcalfe's Law on networks, which asserts that the "power of a network is proportional to the square of the number of nodes in the network". The IN is now working towards an effective networked environment at sea. However it calls for deft organisational planning and effective use of high end technology. The Indian Navy has realised this and is currently working towards NCW.
Logistics: Apart from all the operational related areas, the Navy also successfully uses the networked environment and IT prowess for managing its logistics, maintenance and other day to day administration. Navy runs successfully an "Integrated Logistics Management System" to effectively manage its vast inventories required to maintain warships, submarines and aircrafts.
The repair yards use centralised data banks and a large number of web enabled services akin to an in-house Enterprise Resource Planning system.
Training
Today the Indian Navy can boast of 100 percent IT literacy and men who are enrolled into the organisation are given the basic IT training at the entry level training itself. The Southern Naval Command (SNC) with its headquarters at Kochi has realised the need for IT training in a modern navy and the same is imparted at various levels of training. The Naval Institute of Computer Applications (NICA) located in Mumbai, conducts various types of high end and working level courses on IT for navy.
Simulators and Emulators
With the prices of computational power dropping, audio visual simulators capable of simulating any scenario has not only become affordable, it has become an effective substitution to the costly live equipment for training. Thus today, a student officer can sit for hours on a console as in a bridge of a warship and navigate his ship through a selected port or control his weapon console as in an operations room of a warship. The real scenario with all internal and external factors and even the environmental factors like wind, physical shocks, spatial orientation etc are accurately simulated.
e-learning
The Indian Navy has now embarked on a very ambitious project of e-learning. The project envisages a back bone which connects standardised information portals of the various schools and access nodes located all over IN units. The project also provides facilities like distance learning, on line examinations, video conferencing etc.
