New Delhi, Aug 10: India on Friday night activated the miniature reactor on board the country's first indigenous nuclear submarine INS Arihant.

With this, the country has moved a step towards completing the nuclear troika - capability to launch nuclear weapons from land, air and sea.

According to a news channel report, all systems of the indigenously-made 83 MW pressurised light-water reactor are "go" after many rounds of checking and re-checking.

The 6,000-tonne submarine at the secretive ship-building centre at Visakhapatnam will soon be launched to sea on the Eastern coast.

India is the only nation in the Indian Ocean region to have a nuclear submarine and the sixth in the world to have the capability to design and construct a nuclear submarine

The orange beacon atop the conning tower came to life on July 26, 2009, as Prime Minister Manmohan Singh's wife Gursharan Kaur had pressed the button to symbolise the launching of the vessel into water.

In the middle of the body - comprising an outer hull through which the water goes in and an inner pressurised hull - on the starboard side are two rectangular vents, meant to take in water when the vessel dives into the sea. It is like a "cocoon within a cocoon", an official had explained.

INS Arihant is longer than any of the submarine in the Indian Navy's fleet so far. A nuclear submarine is powered by a nuclear reactor, which generates tremendous heat driving a steam turbine. It has unlimited underwater endurance and speed twice that of its conventional counterparts.

The submarine can carry 12 nuclear missiles K-15. Keeping in line with its "no first use policy", the submarine will help India in developing a "credible second strike capability" in case of nuclear attack, said officials.

Indian Navy has been operating conventional diesel-electric submarines, which have to surface to charge their batteries.

In yet another setback to the Congress party amid the ongoing Lok Sabha elections, its candidate from Indore Akshay Kanti Bam withdrew his nomination on Monday, April 29, days before voting.

Interestingly, he had reached the Collector's office with BJP MLA Ramesh Mendola to withdraw his nomination. He also reportedly joined BJP. 

Senior BJP leader and state cabinet minister Kailash Vijayvargiya in a post on X said Bam was welcome to join the BJP.

"Congress Lok Sabha candidate from Indore Akshay Kanti Bam is welcome in the BJP under the leadership of Prime Minister Narendra Modi, party national president J P Nadda, Chief Minister Mohan Yadav and state president VD Sharma," he said in the post.

The Congress had fielded Bam against sitting BJP MP Shankar Lalwani from the Indore Lok Sabha seat, where polling will be held on May 13.

Kolkata: Defence Minister Rajnath Singh or Transport Minister Nitin Gadkari could have been the prime minister, said Trinamool Congress supremo and West Bengal chief minister Mamata Banerjee, subtly taking a dig at the Bharatiya Janata Party leaders relegated to the second rung of the organisational echelons.

Banerjee’s nephew and the TMC general secretary Abhishek Banerjee, on the other hand, attempted to stoke trouble within the BJP’s unit in West Bengal, saying that at least 10 more state legislators of the saffron party were keen to join his party and in touch with him.

"You (Rajnath Singh) are surviving at the mercy of Modi (Prime Minister Narendra Modi). You are saluting Modi daily to save your chair. You or Nitin Gadkari could have been the PM (prime minister) today," the TMC supremo said in an election rally at Ausgram in Bolpur Lok Sabha constituency on Wednesday. "There would have been no problem...at least there would have been a gentleman in the chair who knows minimum courtesy," she added.

Banerjee was responding to Singh’s diatribe against herself and the TMC government led by her. The defence minister, who had addressed an election rally in Murshidabad on Sunday, had criticised the TMC government for alleged corruption and anarchy in West Bengal.

Singh had referred to the attacks on the Enforcement Directorate officials on January 5 during a raid at the residence of the TMC leader Sheikh Shahjahan at Sandeshkhali in North 24 Parganas district of the state. It was followed by an agitation by local women protesting against atrocities by Shahjahan and his aides known to be owing allegiance to the TMC.

Singh questioned how the state government, led by a woman as the chief minister, could allow such atrocities on women to take place. He went on to say that Banerjee had lost all ‘mamata’ (affection and compassion) for people.

Banerjee shared a cordial relationship with Singh since the days when they both were ministers in the central government led by then Prime Minister Atal Bihari Vajpayee. Singh avoided personally criticising Banerjee in the past.

He, however, went ballistic against Banerjee on Sunday, triggering a strong response from the TMC supremo on Wednesday.

"The BJP is trying to get into the game of breaking parties, but they can't win in it. They poached two of our MPs, and we replied by taking two of their MPs, Arjun Singh and Babul Supriyo. Recently, by using ED raids, they inducted Tapas Ray. At least 10 top leaders of the BJP are in the queue to join the TMC," Abhishek said in another election rally in Murshidabad on Wednesday.

Maharashtra Leader of Opposition Vijay Namdevrao Wadettiwar waded into controversy after he alleged that an RSS-affiliated cop, and not terrorist Ajmal Kasab, killed former state anti-terrorism squad (ATS) chief Hemant Karkare during the 26/11 Mumbai terror attack.

In a video statement released on Saturday, the Congress leader alleged that the bullet that killed IPS officer Hemant Karkare did not come from the gun of Ajmal Kasab or any of the other nine Pakistani terrorists involved in the attacks.

Instead, he claimed it came from the weapon of a police officer allegedly "dedicated to" the Rashtriya Swayamsevak Sangh (RSS).

Wadettiwar also accused Ujjwal Nikam, the special public prosecutor in the case and a BJP Lok Sabha candidate from Mumbai North Central, of suppressing this information, labeling him a "traitor."

He questioned the BJP's decision to nominate Nikam for the Lok Sabha polls, accusing the party of protecting traitors.

“During the probe, key information was out. However, it was suppressed by Ujjwal Nikam, who is a traitor. My question is, why is BJP protecting a traitor and nominating such a person for Lok Sabha polls? By doing this, BJP is protecting traitors," Wadettiwar alleged, Times of India reported.

These allegations drew strong responses from Nikam and Deputy Chief Minister Devendra Fadnavis.

Nikam condemned Wadettiwar's statement as "baseless and irresponsible," expressing pain at the doubts raised over his integrity.

He emphasized the legal steps taken to convict Kasab, calling Wadettiwar's remarks an insult to the victims of the 26/11 attacks.

“What a reckless statement is being made. I am pained by such baseless allegations, raising doubts over my integrity. It clearly reflects the level of electoral politics. I never thought politicians will stoop to such low levels. For political gain? He (Wadettiwar) is insulting not me, but the 166 departed souls and all persons injured in the 26/11 attacks," Nikam said.

He added, “They (Congress) hold Kasab as innocent. Even Pakistan had accepted that Kasab was involved in the conspiracy and in the terror attack on India and was guilty".

He said Indians very well know the legal steps he had taken to ensure Kasab’s conviction.

Nikam said citizens of the nation would on 4 June, the day of results for Lok Sabha polls, give their reply to such allegations, adding he wished not to dignify the “desperate disinformation” with a further response.

Meanwhile, BJP leader and Deputy CM Fadnavis said, “Our alliance is with Nikam, while Congress has joined hands with Kasab".

Shiv Sena spokesperson Kiran Pawaskar said NIA should arrest Wadettiwar and ask him why he was defending Kasab.

Pawaskar criticized the Congress for allegedly supporting terrorists and expressed surprise at the silence of Shiv Sena chief Uddhav Thackeray on the matter.

“From Wadettiwar’s statement, it appears Congress is supporting terrorists who attacked Mumbai. More shocking is the fact that Sena (UBT) chief Uddhav Thackeray has maintained silence over the episode,” he said.
