INS Vikrant Aircraft Carrier (IAC)

[binayak95]

Any idea why INS Vikrant doesn't use bulbous bow?
The bulbous bow modifies the way the water flows around the hull, reducing drag and thus increasing speed, range, fuel efficiency, and stability.
Large ships with bulbous bows generally have twelve to fifteen percent better fuel efficiency than similar vessels without them.

And they increase the acoustic signature of the ship - generate more noise.

Nimitz was a old design.
Gerald R. Ford-class aircraft carrier do contain bulbous bow.

Bulbous bow is advantages for big ships like aircraft carriers.

I believe we should add Bulbous bow to our our next generation destroyers and frigates as it not only improves performance, fuel-efficiency and stability but also helps with sonar performance.

Bulbous bow is found more commonly on commercial ships because they cruise at a set design speed and bulbous bow shapes create destructive interference thereby reducing wave drag. Key word "design speed". You go at a different speed and it might end up causing more harm than good because it creates constructive interference, multiplying the wave drag.
.
So if Indian Navy is not using it on frontline combtants even though our shipyards build ships with bulbous bows for commercial ships regularly, it might be because of a design choice tied to tactics or other operational realities. I'd rather trust the design choices of our Navy here.

circa 2013 an excellent post on the bulbous bow on this forum

Unbanned now, Personal talks are better in PM.. Off-topic ranting on ongoing thread is not allowed.. Sir...Kunal Ji banned him ..!!!

TL;DR
Bow design, indeed Ship design is quite complex and best left to the experts at WDB (erstwhile DND).

Wow, 1 hitjob a day! So Rahul Bedi is also dalal? Never really looked at his work closely. Isn't he the dude that rights for most foreign publications like Janes and The Diplomat?
Maybe we need a thread on DFI to track all dalal defence media persons.

Some good news with regards to INS Vikrant.

"Cochin shipyard to install dozens of Barak-8 missile (LR-SAM) and MF-STAR long range AESA radar onboard INS Vikrant."

After its commissioning?

After its commissioning?

Commissioning doesn't mean that it is ready for active service. Vikrant aircraft carrier still needs radar, weapons, and aircraft to carry.

Why Mototok is the future of pushback tugs

Pushback operations can be time consuming procedures – not least because of conventional pushback tugs.

One question, can we name this thread to just INS Vikrant instead of Indigenous Vikrant class Aircraft Carrier?

So its
2x Kolkata Class
2x Talwar Class
2 x Brahmaputra Class
1 x Deepak class tanker
Can anyone name those 2 smallest ships at the back, behind Brahmaputra? Its not clear.

It's 3 Brahmputra class frigates.

That last one I think is either Saryu class or Kora class.

Saryu likely kora are in eastern fleet
