Comments: Flat Nested Threaded Embedded Oldest First Newest First EMAL !!!!!! By harsha_06 on Tuesday, October 20, 2009 (EST) Good wish by the Indian Navy ! But at what cost will this technology come. Will the US give the nod for selling the technology to India? What will be the cost for fitting it on a 50K ton ship ? Reply to this Comment EMALS By shaz001 on Wednesday, October 21, 2009 (EST) Exact costs of EMALS are not known but is projected to be lot cheaper and easier to maintain than STEAM CATAPAULTS.EMALS is expected to have 122Kj of energy enabling it to launch all future aircraft as compared to 90-95Kjouls of steam catapaults.DRAWBACKS: Electro-magnetic interference with other electronic equipment.It can be easily be fitted on our project 71 aircraft carriers of heavier displacement(60-70,000 tons). Reply to this Comment EMALS By shaz001 on Wednesday, October 21, 2009 (EST) I Think U.S would be more than willing to give us this tech in light of emerging partnerships and signing of EUMA by INDIA.Recent such examples are P-8I DEAL and offer of E-2D HAWKEYE which are futuristic and cutting edge platforms offered to us at same time as U.S FORCES induct them into their armoury.HOWEVER there has been lot of sceptissism/concerns by U.S senators/reps. about the viability and matuarity of such a technology.

B4 they decide on deploying it on my of the future ACs, they should first look into what types of systems will go into the ACs. If it affects the performance of the defensive systems on the ships , then they have to think twice. MO , do a case by case study on each of the ACs and see if it is feasible to deploy EMALS coz who knows we might have a future US/ russian / french defense hardware that we might be interested in and this systems frequency or e-specs might not go well with the EMALS system. ************************************************ It can be easily be fitted on our project 71 aircraft carriers of heavier displacement(60-70,000 tons). ************************************************* How much time will our shipyards take to build this much size ACs ? 20yrs, 40yrs ?????? Reply to this Comment EMALS By shaz001 on Saturday, October 24, 2009 (EST) EMALS is still evolving and is moving towards operalisation on FORD class carriers primarily because the U.S navy seems quite sure of it inspite of critics among influential decision makers. Yes,electromagnetic interference is an issue but benefits outweigh drawbacks:EMALS weighs less,no need for freshwater to generate steam,more energy for launches. Reply to this Comment FUTURE INDIAN AIRCRAFT CARRIERS By shaz001 on Saturday, October 24, 2009 (EST) The 2nd indeginous aircraft carrier is expected to be 60-70,000 tons displacement and enough indications to this has been given by our honourable defence minister recently.The work is expected to begin once the first IAC is launced in 2010. The second IAC is expected to be commissioned by 2017-2018.

The question is not benefits vs drawbacks or what advantages EMALS provides. EMI is a critical factor in designing any electrical hardware. Each electrical system has its own level of tolerance or limits to take any kind of EMI and work properly. Most of the E-Engineers who work on designing or building electrical systems or subsystems from component level know this. Also the level of EMI given out by EMALS may be classified. Now the point is how good is it to leave a big ship like a 60-70K ton aircraft carrier defenseless or with half or some part of its defense systems useless while launching an aircraft. Lets say when launching an aircraft from an EMALS using carrier, one of the ships horizon tracking radars goes offline or if its radar screen gets blurred for a few seconds or if one of its CIWS is down and if an enemy launches a supersonic missile ( in our case the only adversary that has supersonic ASHM missiles is China ) , then the ship and all of its planes are done for. Thats the reason I say it has to be a case by case basis and not a blind approach to take EMALS on every of our future aircraft carriers. Reply to this Comment
