CATOBAR:Indian Navy to use US aircraft launch system in ship

Image result for catobar

 Indian Navy is likely to use advanced catapult-based aircraft launch mechanism (CATOBAR) from United States for its second indigenous aircraft carrier (IAC-II), which is on drawing board

 In this regard, both countries have held several rounds of discussions in joint working group (JWG) on Aircraft Carrier Technology Cooperation (JWGACTC) under Defence Technology and Trade Initiative (DTTI) set up by them.

 EMALS

 For some time, India was exploring possibility of installing US electromagnetic aircraft launch system (EMALS). The US has offered India its latest latest EMALS technology, developed by General Atomics Aeronautical Systems Inc. EMALS uses electric motor-driven catapult instead, which allows launch of much heavier aircraft and reduces stress on aircraft whereas older-generation CATOBAR is powered by steam catapult. It will allow Indian Navy to operate heavy surveillance aircraft, in addition to heavy fighters. However, the system is expensive, something that needs to be factored in

 Background

 The IAC-II has been envisaged to be around 65,000 tonnes and capable of carrying over 50 aircraft. Indian Navy is keen on nuclear propulsion, which will give it unlimited range and endurance, its development in time seems doubtful. India’s first domestic carrier, Vikrant, weighing 40,000 tonnes, is in an advanced stage of construction in Kochi (Kerala). It is scheduled to be launched by 2018-end. It works on Short Take-Off But Arrested Recovery (STOBAR) mechanism similar to that in present carrier INS Vikramaditya, with an angular ski-jump.

Scientists link new virus to kala-azar Scientists have found that parasite called Leptomonas seymouri hosting virus called Lepsey NLV1 may be also responsible for spread of kala-azar  (visceral leishmaniasis). Earlier it was believed that parasite Leishmania donovani (sandfly) alone is responsible for spread of the dreaded infection Kala-azar or visceral leishmaniasis (VL), also known as black fever and Dumdum fever is most severe form of leishmaniasis. It is zoonotic  (or parasatic) infection transmitted by sand fly (Leishmania donovani), a blood-sucking pest, which is one-third size of mosquitoes and found in moist  (humid) mud and sand and in close proximity to livestock.
