I always wondered why not used Hybrid power plants on Large Aircraft career. I understand India does not have nuclear reactor large enough for aircraft career. Why not used the one on Arihant for exclusively powering Aircraft launching mechanism and auxiliaries. While main propulsion could be conventional ? I know this is Jugaad. but why not go for Jugaad for another "relatively" quick career - rather than wait decades for technology to fructify.

Better to go for IEP instead of that. Otherwise you'll add all the negatives of the reactor (most importantly the difficult and costly refueling in around 15 years) and none of the benefits (no sustained high speed cruise).

But thinking about it, French CDG carrier has two 150MWth reactors. So our IAC-2 class, being around 50% heavier) might be able to make do with two CLWR-B2 reactors that are being made for the Project-75A SSN. Those two are 190MWth each. If there is still a shortfall, we can have three reactors. Maybe one CLWR-B1 and two CLWR-B2?

Since Project-75A has already started, CLWR-B2 should be ready in time for IAC-2. Wonder why this is not being pursued. BARC simply said the reactor for such a ship isn't ready.

For reference, future French carrier is 75,000 tons and propelled by two 220MWth reactors. So our 65,000 ton carrier being propelled by two 190MWth reactors sounds fine.

yeah - this too sounds fine. All I wanted to say was why are we hesitating have this jugaad. Heck Navy could have used this reactor and validated its ship usage - by having first built for a battle cruiser.

USN Ford class carriers have reactors of the 385 MW type. They said they only anticipate using half of the reactor's output during the lifetime. They built in a margin in case there are technological upgrades that significantly require more electrical power as a way of future proofing the carriers against technological advances.

like maturation of rail gun, or Laser CIWS

Rail gun is a failed project for now. Laser CIWS has yet to fully mature.

correct- thats why i said maturation of these or some other tech. Anyway Americans like to overdo anything - side effect of having surplus economy.

Japan is building. We are not going to be no.3 any time soon.

Looks like they are building a ship to deploy a Gundam, missile load out would be interesting.

Where are our Nilgiri Class Ships...Sab launch ho rahe hai but ek bhi bhar nahi nikal raha...Ita high time now.

Mortar round ?

 

[Blood+]

Mortar round ?

I think it's for AFVs.

 

[binayak95]

Nothing in comparison to phalanx

But very useful all the same with RF proximity fuse 40mm shells against drones, swarms and helos

 

[binayak95]

Vikrant had Indian gearbox!? Does that mean P-17A has Indian gearbox as well?

Why is this news? ELECON has been making gearboxes for warships for years now

Unnecessary complications. Reactor ops mean a tonne of additional infra for radiation sealing, protection of crew, safety SOPs, et al.

If you are going to have a reactor on board, go full in and have enough power for all operations, instead of complicating logistics and having reactors + Diesel/GT combination like Kirov class. Waste of space, waste of tonnage, expensive, complicated.

Smoke grenades for Tanks, AFC and IFV.

MDL and GRSE are waiting for you to rant on DFI so that they can rush to MoD and say @SUPERPOWER has said it, we must BUILD AS FAST AS FUCK BUOI

Its BMD ship to free the Kongo/Atago and Atago + AEGIS DDGs for fleet tasking

 

[Okabe Rintarou]

These are going to be responsible for BMD of entire Japan. And with only two ships proposed, they'll have to rotate so that only one ship will be on station at a time. Binkov's analysis that these might be moved to defend Senkaku or even Guam is misplaced. India doesn't need such ships as our primary BMD is land-based and Next Gen vessels equipped with AD-1 and AD-2 will suffice for ship-based BMD tasks.

Just for reference, INS Dhruv is 15,000 tons. Without the VLS.

It was news for me because I remember reading about how are destroyers all use Russian GT and gearboxes.
