Indian Boomer Enters Seal Trials

Speaking or Indian defense upgrades, the first Indian built SSBNs has entered sea trials:

In a major step in validation of indigenous defence technologies, the Indian built nuclear-powered ballistic missile submarine Arihant completed its harbour trials and entered the sea here on Monday.

Built under the highly secretive Advanced Technology Vessel project monitored directly by the Prime Minister’s Office, the nuclear-powered submarine emerged from the breakwaters of the Visakhapatnam Harbour under the watchful gaze of a low flying helicopter. The 112 metre, 6000 tonne partially submerged Arihant glided into the Bay of Bengal as part of its sea trials, sailing north along the coast before disappearing into the mist.

The Arihant class is kind of an odd hybrid: It only carries 4 Polaris class missiles or 12 shorter range missiles, and at 6000 tons it's on the smallish size for a missile boat.

It is also the first indigenously designed and built nuclear submarine for the Indians, so it represents a big step forward.
