CHILDREN had the chance to bake and learn about food that sailors on a submarine would have to eat.

The Royal Navy Submarine Museum in Haslar Road, Gosport, invited children of all ages to take part in a summer activity.

Sammy Sardine’s Summer School had children discovering the food that sailors ate on board a submarine during the Second World War.

On board HMS Alliance, children got to see a Frog in the Bog, also known as Toad in the Hole, illustrated by the museum’s Horrible Science of a Submarine exhibition.

Gareth Brettell, education manager at the Royal Navy Submarine Museum, said: ‘Everyone had a great time cooking the different cakes inspired by the submarine.

‘They got to pick their favourite that others had made, then they had the chance to cook their own.

‘They enjoyed making their little cakes with different parts of the submarine in different flavours and ingredients.

‘We had a tropical fruit cake and a coconut and chocolate cake which the kids loved.’

As well as the cooking classes, families who visit the museum can also learn old ways to communicate.

Kids will have the opportunity to learn Morse code, semaphore and how to write using invisible ink.

Once they have mastered this, they can write secret messages and send a signal across the museum.

The communications day is on August 13.

Gareth added: ‘There is something for everyone this summer

Reactor of India’s first nuclear submarine INS Arihant goes ‘critical’

2 Replies

New Delhi: In a major step towards completing its nuclear triad, India activated the atomic reactor on board the indigenous nuclear submarine INS Arihant, paving the way for its operational deployment by the Navy.

“The nuclear reactor on board the INS Arihant has been made critical (activated) last night,” sources said on the development of the nuclear submarine.

Nuclear triad is the ability to fire nuclear-tipped missiles from land, air and sea.

After the nuclear reactor is activated, the agencies concerned can work towards readying the warship for operational deployments soon.

INS Arihant has been undergoing trials at Navy’s key submarine base in Vishakhapatnam and would be launched for sea trials soon since the nuclear reactor has gone critical.

The DRDO has also readied a medium-range nuclear missile BO-5 for being deployed on the Arihant and its last developmental trial was held on January 27 off the coast of Vishakhapatnam.

The nuclear submarine will help India achieve the capability of going into high seas without the need to surface the vessel for long durations.

Conventional diesel-electric submarines have to come up on surface at regular intervals for charging the cells of the vessel.

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.

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