Defence & Security Current Affairs
Indian Coast Guard Ship ARUSH Commissioned
- The Indian Coast Guard ship Arush, the seventeenth in the series of twenty Fast Patrol Vessels (FPVs), designed and built by Cochin Shipyard Limited, was commissioned on May 26, 2016 at Kochi.
- The 50 m indigenous FPV can achieve a maximum speed of 33 knots with an endurance of 1500 nautical miles at economical speed of 13 knots, equipped with state-of-the-art weaponry and advanced communication and navigational equipment.
- The special features of the ship include an Integrated Bridge Management System (IBMS) and Integrated Machinery Control System (IMCS). It is an ideal platform for undertaking multifarious close-coast missions such as surveillance, interdiction, search and rescue and medical evacuation.
- The ship has been named ICG.S Arush, literally meaning first ray of sun, and will be based at Porbandar under the administrative and operational contrql of the Commander, Coast Guard Region (North-West).
INS-Tarmugli Commissioned into Indian Navy
- The Indian Navy on May 23, 2016 commissioned INS-Tarmugli at Eastern Naval Command in Visakhapatnam. The ship is named after an island in the Andaman group.
- It is built by Garden Reach Shipbuilders and Engineers Limited (GRSE), INS-Tarmugli is the first follow-on Water Jet Fast Attack Craft (WJFAC), is an improved version of WJFAC, earlier constructed by GRSE. It is having the 320 tonnes weight, measures 48 m in length and can achieve speeds in excess of 30 knots.
- The ship is capable of operating in shallow waters at high speeds and is equipped with enhanced fire power. Built for extended coastal and offshore surveillance and patrol the warship is fitted with advanced MTU engines, water jet propulsion and the latest communication equipment.
Hypersonic Technology Successfully Tested in Australia
- Hypersonic technology was successfully tested in the Australian desert by a joint US-Australian military research team on May 18, 2016.
- The scientists involved in the programme called Hypersonic International Flight Research Experimentation (HIFiRE)] are developing an engine that can fly at Mach7. HiFiRE is made up of a scramjet engine attached to a rocket booster.
- Scramjet is a supersonic combustion engine that uses oxygen from the atmosphere for fuel, making it lighter and faster than fuel-carrying rockets. This is helpful for flying at hypersonic speed—Mach 5 and above.
- These engines have no moving parts. Instead of the rotating compressor and turbine in a jet engine, air is compressed and expanded by complex systems of shockwaves under the front of the aircraft, inside the inlet and under the fuselage at the rear.
