1. HJ MILITARY NEWS: INDIAN NUCLEAR
SUBMARINE INS ARIHANT BEGINS SEA
TRIALS

2. India’s first nuclear attack submarine
Arihant began Sea Trials on December
15th with naval personnel and
defence scientists on board showing
both caution and confidence.

4. • Arihant's sea trial will include the firing of the
indigenous Bo5 missile that has a 700-km range and
can carry a one tonne nuclear warhead. It can carry
12 such missiles.
• 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.

6. • The vessel, the lead ship of the Arihant-class submarines, was
launched in 2009. Its design is based on the Russian Akula-
1 class submarines and its 83MW pressurised heavy water
reactor has been built with significant Russian assistance.
• While its 100-member crew has been trained by Russian
specialists, Indian scientists at Mumbai's Bhabha Atomic
Research Centre have received significant expertise in
reducing the size of the reactor to help it fit into the 10 metre
diameter hull of the submarine.
