L&T Developing Bond-Style Mini-Sub For Navy?

Indian private firm Larsen & Toubro indicates it is designing and building a swimmer delivery vehicle (SDV). This poster was up at the L&T stand at DefExpo. Under development by L&T Heavy Engineering, this image depicts it as a dry type delivery vehicle for up to four marine commandos.

Executives I spoke to at the stand said it was being developed and built in-house and would be offered to the Indian Navy once it was complete (like the Adamya AUV).

Separately, it is known that in 2012, the Indian MoD approved a navy requirement of four special operational vessels (SOVs) for the MARCOS, apparently to be built at the Hindustan Shipyard Ltd in Visakhapatnam. It is not clear if L&T is involved with that classified programme.

Any idea of endurance??

Everything in India is so filmy? Lol..

Any idea of endurance??

Won't be much.. These types of *SDVs* aren't used lik conventional subs ... Or even midget subs/.

why not GI Joe styled subs

 

[GURU DUTT]

isnt the US navy & mariens using a smillar platform to transport its navy seals commados from there subs to shore

I think they're little different than this.... We've similar ones with our MARCO too i guess

I think this will be something like Advanced SEAL Delivery System (ASDS) ( dedicated for Special Operations),but probably smaller.generally,these kind of subs has range around 100-150 NM.so,you can expect an endurance from 3-4 days to an Week.there are similar subs,but they use wet insertion,not Dry,which is significantly challenging and needs different vehicle than one used for wet insertion.

great news by the way..

Pathetic title but what does one expect from Mr Shiv Aroor?

Nothing all that noteworthy from this news, the MARCOs have had such mini-subs for about 2 decades, they got new ones back in 2012/13 (as noted in the article).


See them in use in this vid:

@SpArK the endurance won't be exceptional as they will be electrically powered (for stealth reasons) and also these are tiny, you're not going to expect Spec Op operators to travel 100s of KMs in these are you?

Not really. The current ones are 'wet'. This is a dry type...the chaps sit in a dry chamber and do not get wet.

This makes very little difference. It means these have slightly extended ranges because hypothermia isn't an issue but that's about it. Nothing huge over what the IN already has for their SOFs.

It's not a midget sub .. Midget subs carry such vessels themselves and can you tell us which midget sub India procured in 12-13?

My terminology was wrong- the IN has had such special operational vessels (SOVs) for some time and these are what the IN procured in 2012/13.

The difference, my friend is on the physical tiredness (fatigue) of the operators, if I may call it, once they hit the insertion point.

INR106 crores for Personal Submarine to let you 'Fly' Underwater
Adventurers with deep pockets can now explore the hidden depths of the ocean, thanks to a futuristic submarine that lets users "fly" underwater.
The DeepFlight Super Falcon, developed by California-based Hawkes Ocean Technologies, is a two-seater, winged submersible that can take passengers on undersea joyrides. The custom-built underwater vehicles are designed to dive below the surface, swim amongst marine animals, deftly navigate through underwater canyons, and even perform aquatic barrel rolls, reported the San Francisco Chronicle.
"It is like an airplane with wings upside down," Graham Hawkes, founder and chief technical officer of Hawkes Ocean Technologies, told the Chronicle. "It is like flying in the air, but we are flying underwater."
The submarine is 21 feet (6.4 meters) long, and has a wingspan that stretches nearly 9 feet (2.7 m). The submersible can carry two or three passengers, depending on the configuration of the vehicle, and can dive to a depth of about 394 feet (120 m). [See Photos of the DeepFlight Super Falcon Submersible]
Traditionally, submarines are constructed with an inner shell and an outer shell. To dive, submarines fill the space between the two shells with water, changing the ship's density and creating so-called negative buoyancy — when the gravitational tug on the sub is greater than the force of buoyancy. When submarines remain on the water's surface, the area between the two shells is filled with air, which again changes the vehicle's density and enables it to float.
The Super Falcon, however, dives underwater like a whale, using thrust to generate "downward lift" to help the vehicle descend below the water's surface. Essentially, the submarine uses lift and drag — the principles of regular flight — to "soar" underwater.
This means the Super Falcon is always positively buoyant — or remains floating unless some mechanical device or additional weight is used — which is a key safety feature of the winged submersible, according to company officials. If an emergency occurs, or the vehicle loses power underwater, it will simply float back to the surface.
"It looks like a James Bond wild machine, but it is positively buoyant, so it's really safe," Karen Hawkes, Graham's wife and the vice president for marketing, told the Chronicle.
Hawkes Ocean Technologies, founded in 1996, got its start designing submersibles for the military and scientific communities. In the mid-1990s, the company began developing winged submersibles aimed at the luxury market.
The Super Falcon currently retails for $1.7 million, and includes on-site pilot and operations training. The vehicles are among the latest high-tech items geared at the super-rich, and the company already boasts some famous clients: Sir Richard Branson, the billionaire British tycoon, has already made several dives in the DeepFlight Super Falcon, and famed American adventurer Steve Fossett commissioned a single-seater sub capable of diving to the bottom of the Marianas Trench before his untimely death in 2007.

Don't you think that there is obvious operational gap between so called wet - special operations vehicles , midget subs to ,conventional diesel subs , nuclear powered subs ....?

I personally feel any technological advancement which can fill this gap ...should be welcomed .

such small sub with less endurance , and less capacity but one that comes with smaller price tag and less maintenance headaches ...may well find itself purpose in broad objectives of Indian navy .

Not all our enemies at sea ..are that well advanced .

do you think that such small sub may be of use in anti piracy operations?

do you envisage any other role for such sub in naval warfare ?
do you think that such sub may have some role in preliminary training ?



I find these mini submarines submarines stunning and charming .

I am sure they can have some naval application ....
