Soooo many!!!!Does India Have any Naval Engines Or Radars
We use a mix of imported and indigenous ones.
Soooo many!!!!Does India Have any Naval Engines Or Radars
Agree with u, i think tejas is a competitor for grippen. But i think grippen navy is for vikrant follow up ac, cuz there is no logic in having this aircraft in ins vishalDon't know why , but I don't really like this SAAB , Specially giving Gripen priority which going to be NG version will surely put doubt on Tejas quality in export market if we ever consider this . Tejas can surly send Gripens export ambition along with intention to replace all existing Mig 21 back to Sweden and can be great export success only if we shows the world that worlds 4th largest airwing trust it.
It will be very bad move , seems Rajib Gandhi era bureaucrats still lobbying for corrupt Sweden and it's 3rd class company whose contribution to Gripen even less that our Indigenous contribution in Tejas .
God sve our country from these mafias.
Does INS Kolkata use one ................Soooo many!!!!

Yes, again a mix!Does INS Kolkata use one ................
WTF INDIA dosent have any s band radarYes, again a mix!

For warships(including aircraft carriers) I have an idea. Instead of flying platforms (helicopter or airplanes with AEW&CS radars) that guzzle fuel and don't give 24/7 coverage, a high powered tethered drone (quad or octo copter) should be employed, perhaps 10,000ft-15,000 ft above the ship! The drone can carry an AESA radar and optical/thermal scanners.The drone will be continuously powered by the ship (and also run a fibre optic cable from the sensors down to the ship) - this will give round the clock coverage!!! These will be dirt cheap and employable on all Frigates, Corvettes, Destroyers and Offshore Patrol boats (both Navy and Coast guard)!!! This is similar to the Aerostats (Nakshatra) that IAF intends to deploy along the borders - but I feel aerostats are too big/clumsy to be carried by ships, where in fact the quad/octo copters would be compact and really cheap and easily maintainable on board!!!
There are currently 75+ large ships (1000+ tonnes) that might qualify for such tethered drones, and in the next few years that number will be 100+. If each of these ships were to have say 250 kms radius of coverage via the tethered drones then just imagine how much of the skies and seas/oceans will be under coverage!!!
Smaller drones (with lesser radar coverage) could be put on some 100+ other smaller patrol boats (200+ tons) of Navy and Coast guard too!!!
The aircraft carrier could still carry an AEW&CS aircraft (if they can - but neither Vikrant nor Vikramaditya can do that!!!). Helicopter based AEW&CS is the only option for Vikrant and Vikramaditya - which could still be used in conjunction with the Tethered drone option. No ship based flying AEW&CS platform can give you 24/7 coverage!!! That's a fact!! They might be of help a couple of hours a day!!!Interesting proposition but I see a flaw in the theory.
The advantage of a carrier-borne AWACS is that if a ship's radar range is 300 kms, then the AWACS can fly ahead and potentially increase it to 500kms.
For a tethered drone to do the same even with a smaller range with 360 degrees coverage, the radar it needs to carry to potentially give a 500 km range needs to be massive to the point that it will be unsustainable for even a high power drone to carry. Just look at the Kolkata's MF-Star radar which gives a 250+ km range and is huge in size.
Thus while a tethered drone is possible it cannot provide any benefit vis a vis an AWACS because it will be to large to efficiently increase radar range and will put a stress on the ship's power as it will need to power 2 high power radars.
I was answering with respect to an AC which carries AWACS but what you say is also pretty sound as well especially with respect to Vikramaditya/Vikrant.The aircraft carrier could still carry an AEW&CS aircraft (if they can - but neither Vikrant nor Vikramaditya can do that!!!). Helicopter based AEW&CS is the only option for Vikrant and Vikramaditya - which could still be used in conjunction with the Tethered drone option. No ship based flying AEW&CS platform can give you 24/7 coverage!!! That's a fact!! They might be of help a couple of hours a day!!!
No radar (however powerful) that is fixed to the ship is a substitute for a high altitude radar. MF-Star may have 250+ km range but it can only see (objects close to the water surface) about 10-15 kms till the horizon, beyond which the earth curves away!! Aircraft and anti-ship missiles (including Brahmos) make use of this fact. They start flying at high altitude and as they approach the ship they keep lowering their altitude until they're skimming the surface of the sea, so that they're invisible to the ship's radar until the aircraft/anti-ship missile is just few tens of kilometers away!!! Further the ship's radar cannot see other hostile ships beyond the horizon!!
Even a low powered radar and a decent electro/optic pod would provide the ship an immensely increase the coverage both on the surface and the 'low altitude sky' that's hidden beyond the horizon!
Airborne AEW&CS platforms (rotary or fixed winged), if available could still be used to peek at farther distances. But continuous coverage via Tethered drone is a force mulitiplier!!! Also, not all ships can carry a helo with AEW&CS radar!!!
Power maybe scarce on a fighter jet, but on a 2000+ tonne ship power is a plenty (especially when you're talking about an additional radar and a drone!!!). In the worst case even if the ship's speed is lowered by a knot (even though unlikely), it is nothing compared to the advantage that the high altitude radar/sensors will provide.
I too wish DRDO could build a prototype and test this out. With about 100+ large ships, the surface and sky coverage the Navy/CoastGuard could get is immense. Not to mention the ships being able to detect low flying anti-ship missiles/aircrafts and hostile ships way ahead in time during combat!!!I was answering with respect to an AC which carries AWACS but what you say is also pretty sound as well especially with respect to Vikramaditya/Vikrant.
Unfortunately ideas such as these can only be verified if they tested out in the field.
Lets hope we see drone projects like these in future from DRDO.
Till then check out this link. Its about radars on UAVs you might enjoy it.

Nope as expected..................................................RIP LCA and gripen
anybody surprised ................................................???????:biggrin2::biggrin2::biggrin2::biggrin2::biggrin2::biggrin2:
well i will rip for gripen but not for lca. As we know Indian version have tendency to get back to life from ICU...............Nope as expected..................................................RIP LCA and gripen
Indian Navy is still operating with the old doctrine of needing only twin engined aircraft for carriers!! With today's reliability of jet engines, single engined jets are pretty good too!!!

All the media houses wanted her scrapped like INS Sindhurakshak. Bloody turncoats.INS Betwa on Even Keel: to be Fully Operational by Apr 2018
INS Betwa, a P-16A Class frigate has been made upright by the unstinted efforts put in by the Naval Dockyard, Mumbai and the salvage firm M/s Resolve Marine, specially contracted for the operation. It may be recalled that, the ship which was undergoing major repairs, had keeled on to her side during her undocking on 05 Dec 2016.
The salvage operations were progressed on a war footing and the initial stabilisation of the ship was achieved by 29 Dec 2016. The complete salvage operation involving complex hydrodynamic calculations and rigging up of intricate measuring and monitoring systems was completed in less than two months.
As the ship was undergoing major refit and mid-life up-gradation since Apr 2016, majority of the equipment/ machinery had already been removed for routine servicing/ replacement with upgraded equipment.
