To date, different types of carbon and alloy steels have proved to be the main materials of choice for naval ship construction around the world. While composites, titanium and aluminium alloys have been utilized for making hulls of smaller vessels such as patrol boats, these materials do not meet the …

Naval Warships now faces wide spectrum of threats from hypersonic missiles, ballistic and cruise missiles, cavitating torpedoes, rail guns, lasers and UAVs. Anti-Ship Missiles are guided missiles most of them of the sea skimming variety, and many use a combination of inertial guidance and active radar homing. A good number …

The US Navy’s “Littoral Combat Ship” program developed a new generation of affordable surface combatants that could operate in dangerous shallow and near-shore environments, while remaining affordable and capable throughout their lifetimes. LCS was designed for countering Asymmetric and A2/AD threats. However according to experts expressed doubt about its power …

ViDAR, or visual radar, is the term coined by Australian computer vision specialist Sentient for a newly developed sensor that combines a high-definition electro-optic (EO) camera with automatic target detection algorithms to detect small maritime targets.   The ScanEagle drone from Insitu  equipped with the ViDAR payload showcased its newest …

A team from Lloyd’s Register, QinetiQ and the University of Southampton in the U.K, has looked towards the future of technology and provided a glimpse of the future these evolving technologies may provide by 2030 in their report “Global Marine Technology Trends 2030.” As humanity is faced with challenges, such …

In recent years, a number of groups have begun researching and building vehicles that can smoothly transition from water to air and back again.   Among these new platforms are the Naviator, a multicopter unmanned aircraft system (UAS) from Rutgers School of Engineering, a quadrotor called CRACUNS built by Johns …

China is developing ever-advancing anti-access, area denial capacity and capabilities, through deployment of long-range aircraft equipped with anti-ship cruise missiles, submarines, surface ships with long-range missiles, and land-based ballistic missiles, putting into risk, any carrier operating within 1,000 miles of the Chinese coast. It is also employing advanced integrated air …

A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of cells, which can hold one or more missiles ready for firing. Typically, each cell can hold a …

Researchers at Penn State Applied Research Laboratory are developing a new system using a technique called supercavitation. Supercavitation is the use of cavitation effects to create a bubble of gas inside a liquid large enough to encompass an object travelling through the liquid, greatly reducing the skin friction drag on …

The US Navy announced  that it will deploy its leading-edge early-warning surveillance aircraft E2D to Japan in February. The Hawkeye will deploy from the USS Ronald Reagan, the aircraft carrier assigned to the Asia-based Seventh Fleet. The Hawkeye can detect cruise-missile and ballistic-missile launches from long range, potentially allowing for the missile …
