Navies of various countries have announced making their warships and submarines  propelled with an electric propulsion system. Instead of driving the ship’s propellers directly, diesel engines turn electric generators, which in turn power electric motors that drive the propellers. This arrangement enables diesels to be placed away from the shafts and …

A nuclear submarine is a submarine powered by a nuclear reactor. The performance advantages of nuclear submarines over “conventional” (typically diesel-electric) submarines are considerable. Nuclear submarines are more powerful than diesel-powered submarines because nuclear reactors powering them can run for years without the need for refuelling. Nuclear propulsion, being completely …

The maritime sector is on the verge of a digital disruption. As digital transformation of the maritime sector is gathering momentum that will have a major impact on operations and existing business models, simultaneously the threat cyber attacks is emerging. Further the  sector’s infrastructure will be exposed  to more and …

A warship or combatant ship is a naval ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a state. As well as being armed, warships are designed to withstand damage and are usually faster and more manoeuvrable than merchant ships. Unlike …

Today’s naval forces rely primarily on highly capable multifunctional manned platforms, such as ships and submarines. Even the most advanced vessel, however, can only be in one place at a time, making the ability to respond increasingly dependent on being ready at the right place at the right time. With …

The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative proposals in maritime communications with an emphasis on undersea and cross-domain (above sea to below sea and vice versa) communications. The Defense Advanced Research Projects Agency wants to build an undersea network so that the military can have situational awareness …

Naval Warfare depends a large extent on lethality and survivability of submarines, its principal weapon, therefore Navies have been researching new ways to make them quieter and increasing their underwater endurance. Propulsion system plays an extremely important role in the functioning of a submarine for the completion of its desired …

Cooperative Engagement Capability (CEC) is a sensor network with integrated fire control capability that is intended to significantly improve battle force air and missile defense capabilities by combining data from multiple battle force air search sensors on CEC-equipped units into a single, real-time, composite track picture (network-centric warfare). This will …

Autonomous Underwater Vehicles (AUV), also known as unmanned underwater vehicle, conducts its survey mission without operator intervention. Their autonomy allows AUVs to be used for missions where a surface vehicle or manned submersible would be at risk, such as mine countermeasure (MCM),  under-ice operations or underwater survey missions such as …
