Why are the Indians so high about their Brahmos？

The missile is REALLY nothing compared with China's YJ-12 and YJ-18，with the former having a range of well over 400km and a cruising speed of Mach 4 plus。This got confirmed in a CCTV programme shown yesterday：

They are not cruise missiles. YJ-22 is, and dont take it personal, your missiles cruise and attain the speed of sound only in the terminal phase, but BRAHMOS's entire flight is supersonic and the fun part is, it takes different trajectories.

And please, we all know what CCTV is capable of. It can even make subsonic missile cruise at the speed of light.

You are wrong。YJ-12 is a supersonic anti-ship missile akin to the Brahmos。The major differences lie in the range and flight speed of the 2 missiles。The YJ-12 is said to have a range of well over 400km（550km according to some sources）and a speed （NOT only terminal stage）exceeding M4。

What about YJ-12B? I heard it has speed of 7M and can go for 2000km.

CCTV is exaggerating things so that you can sleep fitfully. YJ-12's max speed is around Mach 2.5 only. The Mach 4 thing is a myth.

If YJ-12 is so capable, ask your PLAN why no real warship has been integrated with it?? You still carry around the Mach 0.8 C-802 (180km) on most ships. YJ-12 may never have went into mass production thats why so far Ive seen only a small no. of JH-7s with it.

FYI, BrahMos Block-III's range has also been increased to 500-550km -

New modified BrahMos with 500km range | defence.pk

And top speed is Mach 3. You know there are 1,316 BrahMos missiles under construction with many hundred inducted already into IA/IN, and soon in IAF as well. YJ-12 is a failed missile that never went into mass production and its numbers are so small, maybe less than 20.

And its speed is Mach 2.5 not Mach 4.

What about YJ-12B? I heard it has speed of 7M and can go for 2000km.

Most of the chinie cruise missiles will go to sh!t the moment the Mach 7-8 BrahMos-II is tested.

You said it. YJ-12 is said to have a speed of Brahmos. But Brahmos has proven it in every test it has conducted. No matter how long you take this argument, I stick to what I say, your missiles attain Supersonic speeds not before terminal phase.

Vikramaditya to be handed over to India mid 2013

KALININGRAD, November 10 (Itar-Tass) —— The Vikramaditya aircraft carrier (formerly Russia’s The Admiral Gorshkov) will be handed over to India in the middle of next year, the vice-president of the United Shipbuilding Corporation, Sergei Forafonov, told the media in Kaliningrad. He took part in the ceremony of the transfer to the Indian Navy of another frigate (The Tarkash), build at the Baltic shipyards Yantar.

“The negotiations with the Indian side are practically over. The Vikramaditya aircraft carrier will be handed over to the customer in the middle of 2013 after the insulation of boilers has been replaced,” Forafonov said.

He recalled that the insulation of the aircraft carrier’s boilers failed during sea trials.

“It was not designers’ mistake. The insulation materials were used at the request of the Indian side. The partners had not taken into account the factor of vibration and the hull’s deformation while the ship is on the move,” Forafonov said. “As a result, we have the result that we have.”

Forafonov said the boilers would be covered with a different sort of insulation. The Indian partners agreed with that and put their signatures to the specifications of the new coating.

The work will be done at the Baltic shipbuilding plant, which had manufactured the boilers for the aircraft carrier.

“Next year the Vikramaditya will be fully restored and handed over to the Indian side,” Forafonov said, adding that that might happen in June 2013.

Indian naval ship arrives at Indonesian city

Jakarta : An Indian naval sail training ship, which is retracing the route along the monsoon winds, Saturday arrived at Indonesia s Manado city. INS Sudarshini set out on the voyage from Kochi Sep 15 to retrace the sailing trade route of yore along the monsoon winds and arrived at its last port of call in Indonesia at Port Bitung, Manado Saturday, said a press note from the Indian embassy.

Manado is the capital of North Sulawesi province and is known for its breathtaking panoramas of lush mountains, coffee and coconut plantations, orchid gardens and terraced hillsides.

INS Sudarshini s journey to Association of Southeast Asian Nations (ASEAN) member states is part of ongoing celebrations to commemorate the 20th anniversary of ASEAN-India dialogue partnership. Indonesia is the first stop in its historic journey through ASEAN member states.

A colourful welcome ceremony displaying traditional dances from the Manado region was accorded to the crew of INS Sudarshinie. School children wearing colourful dresses played the band welcoming the crew. Raveesh Kumar, deputy chief of mission, embassy of India in Jakarta said the visit of INS Sudarshini will go a long way in strengthening the cultural, economic and diplomatic linkages across the Indian Ocean and reinforcing people to people connectivity.

He was glad that INS Sudarshini received a tremendous ovation during its course of journey through Indonesia for the past one month.

The ships captain, Commander N. Shyam Sunder said that his mission to build bridges across oceans through people to people connectivity has been amply demonstrated by the overwhelming response they received from the Indonesian government and its people at all three ports of call in Indonesia.

Ambassador of India to Indonesia and ASEAN, Gurjit Singh, accompanied by Commander Shyam Sunder would also call on the governor of North Sulawesi.

NEW DELHI: Enhancing its
firepower, the Indian Navy today
commissioned 'INS Tarkash', the
second of its three stealth frigates
being built in Russia, at the Yantar
shipyard in Kaliningrad there.
The warship, which is expected to
sail into Indian waters in
December, was commissioned by
Western Naval Commander Vice-
Admiral Shekhar Sinha, the Navy
said in a release.
The first warship of the series, INS
Teg, had joined the naval fleet
earlier this year.
Armed with the 290-km range
supersonic BrahMos cruise missile,
the warship is part of the follow-
on Talwar class project.
It is also equipped with upgraded
100 mm medium range gun,
optically controlled 30 mm close-
in weapon system, torpedoes,
rocket launchers and advanced
electronic warfare suite.
"The induction of stealth frigate
with an advanced combat suite and
blend of Russian and Indian cutting
edge technologies, will bolster our
role as a key facilitator in
promoting peace and stability in
Indian Ocean region," the Navy
said.
"The warship is commanded by
Captain Antony George -- an anti-
submarine warfare specialist, and
will join the Western Fleet by
December end," it said.
Ambassador of India to Russia, Ajai
Malhotra attended the induction
ceremony along with senior
officials of the Russian government
and the United Shipbuilding
Corporation.
The Russian Navy has also placed
orders for three warships with a
similar configuration for its own
requirements with the Yantar
shipyard.

Stealth Group

Introduction


In the early 90s, the IN formed a stealth team at the Navy's Design Organization to imbibe stealth technologies applicable to warships through study of open source literature on the subject.

The team studied UK's Type 23 frigate, Germany's F-123 frigate, Nato's NFR project, Israel's Sa'ar 5 missile corvette and IN's SNF class destroyer.

The group evolved guidelines for implementing stealth in IN warships.

To implement stealth in its P-17 frigates, the stealth group carried out special studies in collaboration with Ms IABG of Germany for RCS reduction, Ms IR Davis of Canada for IR management, Defense Evaluation and Research Agency (DERA) of UK for acoustic signature management.

The group also mastered the use of signature evaluation software such as RAMSES, NTCS and Auto-SEA-1.

Use of Stealth in IN Ships


Most anti-ship weapons track and home on to a target by sensing its radar, IR or acoustic signature. Stealth primarily involves reduction of these signatures to make detection and tracking of the ship difficult and allow the stealthy ship to detect and engage the enemy ship before being itself detected.

Anti ship missiles typically use their target's radar signature to track and destroy it.

Radar signature of a ship is minimized through Radar Cross Section (RCS) reduction, achieved by shaping of external surfaces such that they deflect most of the radar waves, instead of sending them all back to the radar transmitter. Use of radar absorbent paint can and concealment of exposed deck fitting, weapons and sensors can further reduce reflected radar energy.

Submarines detect, track and attack an enemy ship by its acoustic signature.

Acoustic signature is minimized be reducing the noise generated by a ship's propellers, engines, generators and other operating machinery. If the noise generated loud, not only is the ship more easily detectable, its ability to detect any submarine threat through the use of its own sonar is considerably reduced.

Use of less noisy machinery and low frequency noise and vibration mounts can considerably reduce the acoustic signature, which can be optionally further dampened using visco-elastic material.

Many anti-ship missiles use a ship's IR signature in tandem or as an alternative to its radar signature to attack it.

A ships IR signature is generated primarily by the hot plume emanating from its diesel or gas turbines driving the engines and from solar heating of its deck.

Infra Red Signature Suppression (IRSS) devices are used to reduce the IR signature of a ship's gas turbine and / or diesel engines, as also seawater injection in its exhaust.

Seawater can also be sprayed on superstructure surfaces, mast and funnel to cool them and create mist that diffuses their IR signature.
